Abstract Lignocellulosic biomass is a renewable source containing three main components: cellulose, hemicellulose, and lignin. The three main components can be processed into products that have high added value. Sources of lignocellulosic biomass includes wood, grass, industrial waste, and agricultural residu. Compared to other source, industrial wastes have a higher potential to be utilized without competition for other needs and assist industry in waste treatment. The production of sugar palm starch generate biomass waste which is disposed into the environment which disturbs the surrounding community and is not utilized. To utilize lignocellulosic biomass, pretreatment is a very important step. Hydrothermal is an environmentally friendly pretreatment, without using harmful chemicals in the process. The purpose of this study was to determine the level of solubility of hemicellulose in the hydrothermal pretreatment process of sugar palm starch industrial waste. The hydrothermal method used is liquid hot water with temperature and time parameters, optimization analysis using response surface methodology (RSM). The result obtained is that the liquid hot water pretreatment method is effective in dissolving the hemicellulose from the sugar palm starch industrial waste. The relationship between variables on hemiselulosa response is modeled Y = 7.7-3.04 X1 – 5.67X2 + 0.4250 X1X2 + 1.06 X1 2 + 3.61 X2 2. The optimization results showed the optimum temperature at 195.91°C for 36.725 minutes, with a hemicellulose dissolution of 81.59% and the level of desirability is 0.852.

Full textAbstract:
Bioremediation is a treatment that uses naturally occurring organisms to break down hazardous substances into less toxic or non toxic substances. The microbes are effective in control of pollution due to waste water. The industrial and municipal waste water is analyzed for different Physico-Chemical parameters such as pH, Temperature, TDS, BOD, COD, Total Alkalinity, Chlorides. The collected waste water samples were serially diluted and pour plated on Nutrient Agar medium and incubated at 37˚c for 24 hours. Among 12 bacterial isolates, 4 isolates namely Bacillus subtilis,Bacillus cereus, Escherichia coli and Staphylococcus aureus showed high reduction in BOD&COD in selected waste water sample.The results shows that the COD is removed maximum by Bacillus cereus in textile and sugar mill waste water about 62.88% an 51.7% respectively and 74.21 % removal by Escherichia coli in municipal waste water. The maximum removal of BOD is 82.83% in municipal waste water by Bacillus subtilis. Escherichia coli and Bacillus cereus removed 80.83% and 77.77 % respectively.

Full textAbstract:
The production of polyβ-hydroxybutyrate (PHB) byBacillus subtilisNG220 was observed utilizing the sugar industry waste water supplemented with various carbon and nitrogen sources. At a growth rate of 0.14 g h−1 L−1, using sugar industry waste water was supplemented with maltose (1% w/v) and ammonium sulphate (1% w/v); the isolate produced 5.297 g/L of polyβ-hydroxybutyrate accumulating 51.8% (w/w) of biomass. The chemical nature of the polymer was confirmed with nuclear magnetic resonance, Fourier transform infrared, and GC-MS spectroscopy whereas thermal properties were monitored with differential scanning calorimetry. In biodegradability study, when PHB film of the polymer (made by traditional solvent casting technique) was subjected to degradation in various natural habitats like soil, compost, and industrial sludge, it was completely degraded after 30 days in the compost having 25% (w/w) moisture. So, the present study gives insight into dual benefits of conversion of a waste material into value added product, PHB, and waste management.

Full textAbstract:
The sugar industry must be managed in a manner that encourages innovation with regard to the waste generated throughout the process. The organic load of sugar mill waste is high, as is its potential to pollute water bodies at various stages of the production process, including cooling bearings, mills, sugar cane washing, bagasse waste and cleaning products. It is therefore necessary to identify treatment mechanisms that not only reduce this waste but also return purer water to the environment, combining the reuse of water in various applications. The objective of this study was to analyze the results of the physical and chemical properties of the effluents generated and the principal treatment technologies employed for the remediation of industrial wastewater from sugar factories. The wastewater from Mozambique’s sugar mills has high levels of dissolved or suspended solids, organic matter, pressed mud, bagasse and atmospheric pollutants. The BOD/COD ratio is low (<2.5), indicating the need for secondary treatment or, more specifically, biological treatment. This can be achieved through humid systems built from stabilization ponds, with the resulting water suitable for reuse in agricultural irrigation. In this work, an educational proposal has been developed for engineering students where they learn to calculate and optimize, among other parameters, the natural wastewater treatment and compare it with a conventional wastewater treatment.

In the process of processing agricultural crops, a large amount of waste is generated. Most of them can be used as sources of energy, fertilizers, feed ingredients, raw materials for food, pharmaceutical and other industries, etc. Thus, one of the most promising directions for the development of the agro-processing sector of Ukraine is the implementation of waste transformation technologies into products with high added value. The production of sugar from sugar beets is accompanied by the formation of a large amount of various lignocellulosic wastes, the disposal of which constitutes a major environmental problem. In order to formulate further ways of implementing resource-saving beet sugar production technologies, promising methods of using its waste were studied in detail. The article presents the methods of valorization of sugar production due to the use of molasses, beet tops, and pomace. The development of the agro-industrial complex of Ukraine will be related to the bioprocessing of various wastes, biotechnological methods today are a powerful way to increase the profitability of many food industries, including sugar. A separate important problem of reducing the burden on the environment is the development of technologies for the use of renewable energy sources, the article shows the perspective of using sugar production waste as a source of clean, efficient technologies for obtaining energy, valuable chemicals, including biofuel. The possibility of obtaining ethyl alcohol, food acids, enzymes, protein, baker's yeast, pectin, food additives, biofertilizers, valuable feed components, etc. on the basis of sugar waste has been demonstrated. Some recent research on water purification using hydrogels and photocatalysts, as well as bioplastics based on beet pulp is highlighted. All these technologies are based on the ability of sugar production wastes to ferment quite easily with the formation of a large variety of final and by-products, most of which are useful in various types of human activities. An economic assessment of the feasibility of implementing these technologies with a view to Ukrainian realities requires a more detailed study.

This study investigates the performance of concrete incorporating various recycled fine aggregates, including recycled brick aggregates, Fly Ash (FA), and Sugar Cane Bagasse Ash (SCBA). The test results showed that the mechanical properties were adversely affected when utilizing recycled brick or concrete aggregates, whereas FA or SCBA enhanced them. The water absorption potential of recycled bricks was proportional to the reduction in mechanical properties. FA and SCBA enhanced compressive strength and increased flexural strength up to 175.72% and 225.51%, respectively, at 20% replacement. The inclusion of recycled brick and concrete aggregates raised water absorption, while FA and SCBA significantly lowered it, improving the overall performance.

Full textAbstract:
Pollution of water, waste disposal, and their management is big problem faced by the world today. Industrial waste, agricultural waste, and household waste are best substrates for energy generation. India is one of the leading producers of sugar and dairy products in the world. These industries discharge a bulk amount of wastewater per day without proper treatment during working seasons. Sugar and dairy industry wastewater has high COD and BOD, which is hazardous for aquatic life and human use also. MFC have earned importance in the last few decades due to its ability to generate bioelectricity from all renewable sources, Most of the MFCs have been used to treat different kinds of wastewater, such as sugar, dairy, brewery, domestic wastewater, distillery, rice mill, paper and pulp, swine wastewater, etc.

According to current estimates, industrial effluent discharge has contaminated around one-third of INDIA’s water, solid waste, and other hazardous waste.The bulk of these defaulting industries are petrochemicals, sugar mills, distilleries, leather processing industries, paper mills, agrochemical and pesticide manufacturing sectors, and pharmaceutical businesses.For these industries, surface water is the major waste disposal method.Untreated or ostensibly treated effluents have raised the quantity of surface water pollution by up to 20 times the acceptable limit in 22 seriously polluted locations throughout the world. Almost all water bodies in INDIAwas found to be contaminated by industrial activity. Although the strict guidelines of the Central Pollution Control Board(CPCB) apply to all industries in India, the current state of the environment is far from ideal.

This study aimed to analyze potential industrial solid waste that can be added to soil-cement blocks. A narrative literature review was conducted in the Scopus academic database, using as the search criteria keywords related to the topic, such as soil-cement, building materials, soil-cement blocks, soil-cement bricks, physical and mechanical properties, solid waste, life cycle analysis, and civil construction. A variety of industrial solid waste that can be incorporated into soil-cement blocks was observed, such as waste rock, sludge from water treatment plants, wood sawdust, polyethylene terephthalate fibers (PET), vegetable fibers from loofah, hemp fibers, rice husks, brachiaria grass, poultry eggshells, sugar cane bagasse, wheat and barley straw, welding slag, foundry sand, waste from quartzite mining, construction, and demolition, mechanical turning, pulp industry grains, and steel mill co-products. Among the investigated wastes, those that improved the physical and mechanical properties of the soil-cement blocks were grains from the cellulose industry, rice husks, Brachiaria grass, steel by-products with granulated soil-cement blocks and blast furnace slag. The waste that produced no satisfactory results was sludge from a water treatment plant, sugarcane bagasse, and vegetable loofah. Through this research, it was possible to verify that the behavior of soil-cement blocks is influenced by several factors in their manufacture, mainly regarding the type and percentage of incorporated waste. However, it is important to be concerned with its application in waste blocks so as not to increase the environmental impacts in the long term.

In the recent years there has been a growing concern over the problem of municipal and industrial waste disposal. In India city sewage, distilleries, tanneries, breweries, sugar mill and food processing units are the major source of organic pollution in water resources. Our growing concern about the availability of clean environment/water makes us more conscious to develop effective and beneficial treatment technologies for the liquid wastes. Anaerobic treatment of liquid waste, having high concentration of biodegradable organic matter, is a competent method to overcome this problem. With the aid of anaerobic treatment technology such wastes can be used to extract some useful products/by products and energy, like-biogas. Biogas is a clean and effective substitute of other conventional energy sources, i.e. coal. The paper highlights major issues of anaerobic treatment along-with the cost economics.

Abstract: Zeolite synthesized from fly ash are crystalline micro porous alumino-silicates solids containing cavities and channels of a molecular size. By introducing extra framework species into these alumino-silicates matrix depending on the type of species introduced, the physicochemical properties and the reactivity of the resulting material can vary drastically. The extra-framework species of fly ash aluminosilicates were modified by ion exchange treatments to prepare materials in which transition metal species are well-dispersed, well-mixed and highly accessible to reactants. The adsorption behavior of the zeolite materials synthesized from coal fly ash for waste water treatment. The zeolites used were zeolite HY and zeolite HZSM-5. Waste water samples were collected, from the bore wells of sugar factory affected areas of Nanded District and effluent waste water along the sugar industry effluent stream. Then water samples were treated with zeolite material by conventional ion exchange method and again analyzed for the comparison. In order to achieve the greatest efficiency of the process and to optimize the degree of removal during the application of the sorbent material for effluent treatment, the effect of type of adsorbent, the effects on adsorption of the solid to liquid ratio during the ion exchange, and effect of contact time were tested. Water samples were collected before and after treatment were analyzed for the various parameters like pH, EC, COD, TDS, hardness etc.

The main goals for the design of waste water treatment plants are high efficiency, high operational reliability and minimal costs. The challenge to have very low investment costs especially exists for industrial plants which are only in operation for several months every year as e.g. in the beet sugar industry in Central Europe. A case study of an Austrian sugar factory treatment plant shows that using very simple and low-cost structures does not affect the efficiency of the treatment. This factory is also one of the rare cases where biologically treated effluent is recirculated to reduce fresh water consumption. Special emphasis is put on the start-up process, the influence of shock loadings in the influent, and design and operation of the plant.

Managing liquid waste from the laboratories of Integrated Agricultural Unit (IAU) of Zuénoula (Côte d´Ivoire) is a major concern for the decision-makers of the company, who are working to solve this problem in their sustainable development policy. This work aims at quantifying liquid waste from the agronomic laboratories and factory of IAU of Zuénoula and to assess their level of pollution. The quantities of waste produced daily are estimated at 28.5 L, 52.6 L and 2600 L respectively for waste from the agronomy laboratory, the factory laboratory and from the rinsing water from latter's glassware. The following parameters were analyzed, temperature, pH, conductivity, turbidity, total suspended solids, COD, BOD5, total nitrogen, total phosphorus, zinc, copper, lead and mercury. The results of these analyzes generally showed that waste produced did not comply with national standards. In particular, the level of lead was very high in these liquid wastes and reached 160 times the standard value. These results require a waste treatment system, which would reduce all the parameters, in particular those of the most noxious metals (lead and mercury).Keywords: Heavy metals, Pollution, Industrial unit, Ivorian standards, Wastewater.

The Bio-Circular-Green Economy initiative adopted in Thailand encourages using sugar mill by-products for food production, benefiting both farmers and the environment. This study assesses the feasibility of applying by-products from the sugar mills and distilleries into sugar plantations for irrigation, fertilization, and soil conditioning. It addresses challenges in sustainable waste utilization and offers recommendations. This study reviews literature, conducts preliminary surveys, and analyzes samples from sugarcane fields in Kanchanaburi, Thailand. The findings reveal that while vinasse and filter cake demonstrate promise as soil conditioners, their application requires careful consideration of soil type and pre-treatment processes. Vinasse, rich in essential nutrients, can benefit sandy soils by improving microbial activity and nutrient availability. Filter cake exhibits positive effects on soil texture, water permeability, and mineral content. Treated wastewater can be used for ferti-irrigation. However, about one-third of farmers lack confidence in its use due to concerns about limited nutrient availability, high transportation costs, and potential negative impacts on health, agriculture, and the ecosystem. To enhance farmer adaptability and ensure the successful utilization of waste, several challenges must be addressed, including: (1) assessing financial and technical feasibility of waste transportation and value-added products, (2) overcoming regulatory barriers related to transportation and utilization of industrial wastes, (3) disseminating knowledge to farmers regarding proper fertilization and waste utilization practices, and (4) implementing long-term monitoring on ecosystem health and conducting sustainability assessments of the waste utilization to affirm sustainability attainment.

The problem of proper disposal of solid waste generated in different industrial processes is one of worldwide environmental concerns nowadays. Thus, this study aimed to establish a new alternative for the disposal of two agro-industrial residues employing them to produce particleboard for different purposes in building construction. The focus was given to the reuse of the sugarcane bagasse (SB) originated during the processing ofSaccharum officinarumfor sugar and ethanol production, and bamboo stem leaves ofDendrocalamus giganteus(BB). For this, six particleboards were produced in the following compositions: with 100% SB, 75% SB + 25% BB, 50% SB+50% BB, 40% SB +60 BB, 25% SB+ 75% BB and 100% BB in the total mass of the composites. The particleboards physical characterization followed Brazilian Standard ABNT NBR 14810-3 to density, moisture content and water absorption. Results showed these raw materials are compatible to particleboard production.

Industrial wastewaters often contain heavy metal ions that are toxic to many living species. Therefore, economic treatment methods are investigated, involving the sorption of metal ions onto wastes or natural materials. In the present work, the ability of sugar beet pulp, a common waste of the sugar industry, to remove Pb2+ polluted waters is investigated. The kinetic and equilibrium experiments were performed in batch reactor in order to determine the Pb2+ adsorption mechanisms onto the polysaccharide. The dynamic studies of Pb2+ fixation onto the natural polysaccharide involve an adsorption reactor coupled with microfiltration membrane in order to confine the adsorbent particles. A mass balance model based on the Langmuir equilibrium isotherm was used to describe the Pb2+ breakthrough curves. This model successfully simulated the entire breakthrough curves whatever the operating conditions used. It provides a useful tool for process simulation and optimisation.

Reducing sugars produced from agro-industrial wastes by means of hydrolysis represent a promising alternative of chemicals and energy. Yet, large scale production still struggles with several factors involving process complexity, sugars degradation, corrosion, enzyme recyclability, and economic feasibility. More recently, sub and supercritical water hydrolysis has been reported for the production of reducing sugars as a readily available alternative to acid and enzymatic biomass hydrolysis. Accordingly, in this work, the results of batch and semicontinuous lab scale subcritical water hydrolysis experiments of agro-industrial wastes of pea pot and corn stover are discussed. Experiments were carried in the temperature range 250 to 300 °C, pressures up to 3650 psi, residence times up to 30 minutes in batch mode operation, or water flowrates up to 12 mL/min in semicontinuous mode operation. Produced sugars were assessed in the effluent of each experimental run by means of dinitrosalicilic acid method (DNS). A maximum total reducing sugar (TRS) yield of 21.8% was measured for batch pea pot subcritical water hydrolysis experiments at 300°C, 15 minutes, 3650 psi, and 1:6 biomass to water mass ratio. Semicontinuous subcritical water hydrolysis of corn stover showed a maximum TRS accumulated yield of 19% at 290 °C, 1500 psi, and water flowrate of 9 mL/min. The results showed the feasibility of producing reducing sugars from agro-industrial wastes currently discarded through subcritical hydrolysis.

The paper evaluates the question of whether a combined anaerobic-aerobic or a solely aerobic treatment of some particular industrial wastewaters leads to better results. Therefore three different industrial wastewaters were treated in two different process lines: one line consisted of anaerobic treatment prior to aerobic treatment and in the other, only aerobic treatment was applied. The experiments were run with wastewater from:–the pectin industry–the sugar industry (beet sugar)–the animal pulp industry. The data presented in this paper were gained from experimental work which was conducted over a period of two years. Different scales of treatment plants were used. The anaerobic treatment was done in full- and semitechnical scale reactors, while the aerobic treatment took place in labscale and semitechnical scale plants. Surprisingly in all three cases the solely aerobic treatment led to slightly better results in terms of residual pollution. Finally the paper presents data gained from a recently built, full-scale anaerobic-aerobic process which treats pectin waste. The aerobic stage of the process was designed on the basis of the results from the experimental work which was mentioned above. The results from the former experimental work and from the full-scale operation are compared.

The feasibility of producing hydrogen from various industrial wastes, such as vinasses (sugar and tequila industries), and raw and physicochemical-treated wastewater from the plastic industry and toilet aircraft wastewater, was evaluated. The results showed that the tequila vinasses presented the maximum hydrogen generation potential, followed by the raw plastic industry wastewater, aircraft wastewater, and physicochemical-treated wastewater from the plastic industry and sugar vinasses, respectively. The hydrogen production from the aircraft wastewater was increased by the adaptation of the microorganisms in the anaerobic sequencing batch reactor.

Spatial and temporal changes in the pH, electrical conductivity (EC), TDS, TSS, BOD, COD and concentration of toxic metals viz. cadmium (Cd), iron (Fe), chromium (Cr), lead (Pb), nickel (Ni), zinc (Zn) and copper (Cu) were assessed in the waste water contaminated with untreated or inadequately pretreated industrial effluents from pharmaceutical industries located in Selaqui area and sugar industry and distillery located in Doiwala area of Dehradun. Four effluent samples A, B, C, D collected from manufacturing and processing industries located in the study area and two ground water samples E1 & E2 contiguous to Selaqui industrial hub and Doiwala industrial stretch respectively, were analyzed using standard physico-chemical methods. In order to delimit the temporal changes in parameters, samples were collected in three batches at three consecutive seasons of a year. Analyses at STP condition revealed that pH values of ground water samples remained fairly unchanged at 7.01 + 0.14 & 6.98 + 0.04 for E1 & E2 respectively, for two regional variations and three seasonal variations. EC (mmho/cm) varied non-uniformly with highest value of 0.479 observed for sample A in batch 1 whereas lowest value of 0.122 recorded for sample D in batch 3. TDS in effluents of distillery and sugar industry were found to be 3-6 folds higher than the same for effluents from pharmaceutical industries across all seasons. BOD and COD values for the effluents of distillery and sugar industries were recorded unexpectedly higher than corresponding values in effluents from pharmaceutical industries in all the three batches. TSS was very high in the range of 1500 to 4500 mg/l in all the effluent samples except the ground water samples. Highest concentration of heavy metal detected was iron with concentration of 10.80 mg/l. Cr, Pb, Cd and Ni were found to be above the permissible limit recommended by WHO standards. A plausible analysis is made to interpret the wide range variation of the parameters in the light of spatial and temporal change aspects and necessary pretreatment measures to bring down the magnitude of contamination within consent level are suggested.

Abstract <strong>Background/Objectives:</strong> Irrigation water at Phuleli and Akram canals carry the waste of Hyderabad city and other places on the way to rice fields at lower part of Indus Plain. The long term use of arsenic contaminated irrigation water can accumulate arsenic in rice soils. This study evaluated total arsenic in irrigation water and transported load to rice sites, in addition to the arsenic concentration in main canals and waste sites on the way to Badin. <strong>Methods:</strong> Atomic absorption spectrophotometer equipped with hydride vapor assembly was used to analyze the arsenic concentrations in irrigation water. <strong>Findings:</strong> Currently, the irrigation water quality was generally within the permissible limits of FAO for rice. All types of wastes (14.62-37.2 µg L<sup>-1</sup>) entering the Phuleli and Akram canals (7.08 µg L<sup>-1</sup>) on the way contributed to total arsenic (6.30-57.12 µg L<sup>-1</sup>) in irrigation water at the entrance of rice sites. However, higher arsenic contamination in irrigation water was due to sugar industry waste (37.2 µg L<sup>-1</sup>) and lowest due to city waste of Badin (14.62 µg L<sup>-1</sup>). The data indicated that mean total arsenic concentration from irrigation water would load 0.12 and 0.14 mg kg<sup>-1</sup> of arsenic annually in soils on the basis of net 1000 and 1300 mm a<sup>-1 </sup>water application to rice, respectively. <strong>Applications/Improvements:</strong> The results clearly indicated that waste added from different sources may aggravate the arsenic contamination of canal water and yet the accumulation in rice fields will keep on increasing. It is suggested that waste must be treated before releasing to prevent contamination of rice field. <strong>Keywords: </strong>Arsenic load, City waste, Contamination, Industrial waste

The disposal of untreated industrial effluent into receiving water courses has become a major environmental challenge being faced by most of the developing countries. The high-strength and toxic wastes are responsible for a variety of water-borne diseases. In Pakistan numerous industrial units that dispose their effluent directly into receiving stream without any treatment. This study was, therefor designed to assess the wastewater characteristics of some major industrial units in the surrounding area of River Kabul, which is one of the most signifi cant resources of water in the north region of the country.The main objectives of this study were to evaluate the wastewater characteristics of some major industrial units in terms of BOD (Biochemical Oxygen Demand), COD (Chemical Oxygen Demand), and TSS (Total Suspended Solids) etc. For this purpose, various representative samples were collected from the major industrial units like sugar, paper, ghee (Butter) and textile mills, and were analyzed using standard laboratory techniques. The results indicates that the BOD of sugar, paper, ghee (butter) and textile mills is in the range of 2235mg/L, 1150mg/L, 844mg/L and 745mg/L, respectively. Whereas, the COD of sugar, paper, ghee and textile mills was noticed to be 3945mg/L 2045mg/L, 2240mg/L and 1244mg/L respectively. Owing to the disposal of such highstrength wastes water without treatment, a remarkable increase in the TSS from 96 to 382mg/L, and decrease in DO (Dissolved Oxygen) concentration from 8.8 to 6.7mg/L of River Kabul was observed. The results of this study suggest that all the wastewater coming from the industrial sources should be properly treated as an integral part of their production before their fi nal disposal into River Kabul to secure its natural water quality.DOI: http://dx.doi.org/10.3126/hn.v8i0.4924Hydro Nepal: Journal of Water, Energy and Environment Issue No. 8, 2011 JanuaryPage: 44-47Uploaded date: 23 June, 2011

Currently, need for wood as a raw material for making boards has increased, which has reduced the availability of forest resources. To overcome this problem, industrial waste or other lignocellulosic materials are used to make particle board with the aim of efficient use of wood. Particle board has advantages, namely the use of raw materials can be either wood or non-wood waste. Therefore, particle board processing can overcome the problem of handling wood waste which has not been optimally carried out. This research aimed to analyze the physical properties of particle board made from bamboo and sugar palm waste. This study used an experimental method with a completely randomized design (CRD) with one factor (adhesive content), namely 10%, 12%, and 14%. The results of this study showed that physical properties of bamboo particle board at adhesive content of 10%, 12%, and 14% ranged from, respectively: water content (10.26%, 9.96%, dan 9.79%); density (0.69 gr/cm3, 0.68 gr/cm3, dan 0.71 gr/cm3); thickness swelling (21.57%, 20.07%, dan 19.23%). While the palm sugar particle board with adhesive content of 10%, 12%, and 14% respectively: water content (11.29%, 10.91%, dan 10.22%); density (0.70 gr/cm3, 0.69 gr/cm3, dan 0.71 gr/cm3); thickness swelling (26.00%, 22.90%, dan 22.85%). From the physical properties of the two types of particle board, the water content and density of particle board fulfilled JIS A-2003 standard, while thickness swelling did not fulfilled JIS A-2003 standard. Based on the value of moisture content and density, the use of bamboo particle board and palm sugar is suitable for interior materials.

Coconut plants are very potential commodities, all parts of the coconut plant are beneficial to the needs of human life. All parts of coconuts are not wasted and can be used to produce industrial products. The partners are coconut farmers who sell peeled coconut and coconut flesh. Farmers in Margomulyo village have difficulty in handling the waste of untreated coconut water. Sometimes the coconut water causes inundated land without being used. Sometimes when the coconut water is not directly absorbed in the ground, it will cause bad odor in the environment. Therefore, the use of coconut water is a way to optimize the use of coconut fruit. The content of sucrose sugar in coconut water will be used by Acetobacter xylinum as a source of energy, as well as a carbon source to form metabolite compounds such as cellulose that form Nata de Coco. In conclusion, Nata de coco making training in Margomulyo village gave positive response for the community to establish business unit. The barrier to the implementation of this activity was that there was no solution for handling waste production of Nata de coco of which aroma was quite disturbing. Thus, the implementation of nata de coco waste treatment program will be overcomed in further implementation of community service program which will be held in the next period

In the present investigation the effect of the urban environment of the city of Xalapa, Ver., México in the depth carbonation in Sustainable Concrete made with Agro-Industrial and Industrial Waste Materials like Sugar Cane Bagasse Ash (SCBA) and Silica Fume (SF), was evaluated. The Sustainable Concretes and the Conventional Concrete (Concrete of reference) were designed for a relation water/cement= 0.65 according to the indicated for the ACI 211.1. The Conventional Concrete was elaborated with 100% of Portland cement, and the Sustainable Concretes with partial substitution of Portland cement for the waste of SCBA and SF in percentages of 10, 20, 30, 40, and 50%. The results through the application of phenolphthalein, indicate that the Carbonation depth is proportional to the increase of the substitution of Portland Cement for agro-industrial and industrial waste. The sustainable concrete with 50% of substitution of SCBA-SF presents the worst performance, with a carbonation depth of 1.48 cm, which represents an increment of more of 350% than the conventional concrete at being exposed for one year to the present environment of study.

The evolution of lignin, five- and six-carbon sugars, and other decomposition products derived from hemicelluloses and cellulose was monitored in a sulfite pulp mill. The wastewater streams were characterized and the mass balances throughout digestion and total chlorine free bleaching stages were determined. Summative analysis in conjunction with pulp parameters highlights some process guidelines and valorization alternatives towards the transformation of the traditional factory into a lignocellulosic biorefinery. The results showed a good separation of cellulose (99.64%) during wood digestion, with 87.23% of hemicellulose and 98.47% lignin dissolved into the waste streams. The following steps should be carried out to increase the sugar content into the waste streams: (i) optimization of the digestion conditions increasing hemicellulose depolymerization; (ii) improvement of the ozonation and peroxide bleaching stages, avoiding deconstruction of the cellulose chains but maintaining impurity removal; (iii) fractionation of the waste water streams, separating sugars from the rest of toxic inhibitors for 2nd generation biofuel production. A total of 0.173 L of second-generation ethanol can be obtained in the spent liquor per gram of dry wood. The proposed methodology can be usefully incorporated into other related industrial sectors.

The degradation of agro-industrial waste-based particle boards reinforced with sugar cane bagasse was evaluated by comparing their physical and mechanical properties. The particle boards were prepared with sugar cane bagasse particles (85% by weight of composite) and mixed with bi-component polyurethane resin based on castor oil (15% by weight). After mixing for 2 to 3 min, the resulting mixtures were pre-pressured. Standard molding conditions were: temperature, 100°C; pressure during heating, 5 MPa; and heating time, 10 min. The dimensions of the particle boards produced in the laboratory were 0.40 m x 0.40 m x 0.01 m. The boards were cut into testing specimens with dimensions 0.25 m × 0.05 m × 0.01 m. The accelerated aging test was carried out based on the ASTM D 1037 standard in order to determine the main factors that cause degradation and to identify their influence. The test consists of cycles of six treatment steps, i.e., immersion in water at 49°C for 1 h, steaming at 93°C for 3 h, freezing at-12°C for 20 h, drying at 99°C for 3 h, steaming at 93°C for 3 h, and drying at 99°C for 18 h. This cycle was applied six times for all specimens. Modulus of rupture (MOR), modulus of elasticity (MOE), internal bonding strength (IB), water absorption (WA%) and thickness swelling (TS%) were measured before and after the cycles of accelerated aging. The performance of the particle boards before accelerated aging presented acceptable mechanical performance, MOR: 21.86 ± 2.16 MPa, MOE: 2.77 ± 0.26 GPa, and IB: 1.18 ±0.40. The performance of the particle boards decreased after accelerated aging showed, MOR: 6.25 ± 0.70 MPa, MOE: 0.52 ± 0.10 GPa, and IB: 0.15 ± 0.07. The results were influenced by the temperature, relative humidity and warm water. After the accelerated aging process, the materials showed mechanical behavior similar to Low-Density grade Particleboard (LD1).

Cassava solid waste (Onggok) is a by-product of the starch industry containing a lot of fiber, especially cellulose and hemicellulose. It has the potential to be converted to bioethanol. This work aimed to evaluate the effect of feedstocks ratio for the optimal bioethanol production via enzymatic and acidic hydrolysis process in a batch fermentation process. The effect of alpha-amylase and glucoamylase activities was studied. The sulfuric acid concentrations in the hydrolysis process in converting cassava into reducing sugar were also investigated. The reducing sugar was then fermented to produce ethanol. Enzymatic and chemical hydrolysis was carried out with the ratio of onggok(g)/water(L), 50/1, 75/1, and 100/1 (w/v). In the enzymatic hydrolysis, 22.5, 45, and 67.5 KNU (Kilo Novo alpha-amylase Unit) for liquefaction; and 65, 130, and 195 GAU (Glucoamylase Unit) for saccharification, respectively of enzymes were applied. The liquefaction was carried out at 90-100⁰C for 2 hours. The saccharification was executed at 65 ⁰C for 4 hours. Meanwhile, the acidic hydrolysis operating condition was at 90-100 ⁰C for 3 hours. The fermentation was performed at pH 4.5 for 3 days. Fourier Transform Infra-Red (FTIR) analysis was conducted to evaluate the hydrolysis process. The highest ethanol was yielded in the fermentation at 8.89% with the ratio of onggok to water 100:1, 67.5 KNU of alpha-amylase, and 195 GAU of glucoamylase. Ethanol was further purified utilizing fractional distillation. The final ethanol concentration was at 93-94%.

The utilization of sugar beet fiber (SBF) and rice-based distillers dried grain (RB-DDG) as a source of food ingredients is a prime focus of this short study. SBF and RB-DDG are extracted from waste sugar beet pulp produced in the sugar industry and grain-based distillery respectively. The mixture of SBF and RB-DDG has been given the name HNFP (Healthy nutrients-rich fine powder). The oven drying, grinding, mixing, and mesh screening were used for the preparation of HNFP from the two raw industrial wastes. HNFP has components, Carbohydrates, proteins, fibers, vitamins, and minerals. Which has the potential to be utilized as an essential food ingredient. The prepared HNFP has obtained results that show cation exchange capacity, water holding capacity, and oil binding capacity as 0.5 mEq/gm, 8.5 gm/gm, and 1.95 gm/gm respectively, or the average swelling capacity 12 ml/gm was obtained. These properties complete the requirements of good food ingredients for the human gut system. This communication is the first article that represents an idea that will analyze the use of HNFP as a food additive extracted from sugar beet fiber with a combination of high nutrients rich rice-based distillers dried grain (RB-DDG).

Waste management is a major problem to which the agricultural and food industries must find solutions. The latter use pineapple in most of the processes for the manufacture of fruit juices. These processes result in tons of waste that are often abandoned on dumps near the processing plants, polluting the water table and the quality of surface water after drainage by rainwater. Our study therefore proposed to find an efficient solution to this problem by valorizing agro-industrial pineapple waste in animal feed. Thus, the physicochemical parameters of pineapple peelings and soybean cakes were determined following protocols of French standards. From the results obtained, it appears that pineapple peelings are rich in fermentable sugars, especially cellulose, a source of energy (34% DM) but poor in total nitrogenous matter (6.86%). As feed is a source of protein, soybean meal was added to pineapple peels for enrichment in total nitrogenous matter. The characterized soybean meal showed that it contains 33.46% of total nitrogenous matter. A more complete characterization of the formulated feeds will have to be carried out for their better use in animal feed.

The present study was undertaken to formulate and compare the nutritional worth of conventional urea molasses multinutrient block (UMMB) with UMMB containing spent sugar syrup (SSP) from aamla (Phyllanthus emblica) preserve (murabba) industries, sundried waste bread (WB) and/or tomato pomace (TP) in buffaloes. The wheat flour and oil mustard cake in the conventional UMMB were replaced, respectively, with WB and TP on nitrogen basis, while molasses was replaced by SSS on weight by weight basis. The blocks were iso-nitrogenous and iso- caloric as indicated by comparable CP and EE contents in different UMMBs. Male Murrah buffaloes (12; 5–6 yr old; 456.8±5.3 kg body weight) randomly distributed into 3 equal groups were offered either conventional-UMMB, UMMB containing SSS (SSS-UMMB) or UMMB containing SSS, WB and TP (SSS-WB-TP-UMMB) for 45 days. In addition to the respective UMMBs, the animals in all the groups were offered 1 kg conventional concentrate mixture, 5 kg green fodder and 9 kg wheat straw. The daily intake of block varied from 0.49 kg (SSS-UMMB) to 1.08 kg (conventional-UMMB). Simultaneously, each diet was fed to 3 rumen fistulated male buffaloes to assess the impact on rumen metabolites. The DM and water intake, digestibility of nutrients, concentration of rumen metabolites, blood profile, urinary purine derivatives and N-retention were statistically comparable in all the groups. All the animals maintained their body weights. It was concluded that agro-industrial wastes like spent sugar syrup, waste bread and tomato pomace could be incorporated into UMMBs without any adverse effect on palatability, nutrient utilization or health of animals. Above all the preparation of UMMB could be economized and conventional ingredients could be spared for more vulnerable species.

Full textAbstract:
The sugar factory located in Palleko Village can produce air pollution and waste which is suspected to pollute the environment and waters. Environmental pollution in the form of lead metal can contaminate water and soil around industrial plants. Environmental pollution in water is thought to be higher than on land because it is polluted from mining processes and industrial waste. Lead metal is thought to be able to contaminate plants in water, for example kale, which is a mediator of the spread of heavy metals in living things due to the entry of these metals into plants through roots and leaf mouths (stomata). Water spinach that grows around industrial factories is at risk of being exposed to pollutant substances such as lead (Pb). Lead consumed can cause symptoms of chronic poisoning, paralysis, can affect the circulatory system, nervous system, urinary system. This study aims to identify lead (Pb) in water spinach (Ipomoea aquatica forsk) in Palleko Village, North Polongbangkeng District, Takalar Regency. This research was conducted by laboratory observation with purposive sampling technique using the color reaction test as many as 9 samples. The results showed that of the 9 samples of water spinach (Ipomoea aquatica forsk) examined, the results were all negative for lead metal. it was concluded that water spinach does not contain lead so it is safe for consumption according to the Decree of the Director General of Drug and Food Control Number 03725/B/SK/VII/89 concerning the maximum limit of metal contamination in food is 2.0 mg/kg.

Lignocellulosic fungi are highly versatile organisms with valuable applications in bioremediation processes, including the biodegradation of agro-industrial effluents. In this work, the use of a native strain of the white-rot fungus, Pycnoporus aff. sanguineus, in the bioremediation of the sugar industry waste called vinasse was studied, originating from the San Martín del Tabacal Sugar Mill, located in the north of the Salta province, Argentina. We studied, under controlled laboratory conditions, the bioremediation process of three concentrations of vinasse (5, 10, and 25% in distilled water) with a native isolated strain. The results showed biomass growth at all three tested concentrations, with a maximum at the highest vinasse concentration (25%), while the percentages of color and Chemical Oxygen Demand (COD) removal indicated that the most efficient treatment was with 10% vinasse. The results obtained are promising for the treatment of effluents from the sugar industry using white-rot fungi, considering the valuable subproducts of Pycnoporus spp. biomass.

Full textAbstract:
Waste solid residue from the hydrothermal extraction of pectin derived from sugar beet pulp was used as feedstock in the production of 5-hydroxymethylfurfural (5-HMF). The depolymerization of pectin-free sugar beet pulp (PF-SBP) to monosaccharides and their dehydration to 5-HMF were conducted in subcritical water using a batch reactor. The experimental design methodology was used in order to model the hydrothermal process and to optimize the operational parameters of the reaction, namely temperature and holding time. These parameters are required to achieve the highest yield of 5-HMF. The model predicts, in good agreement with experimental results (R2 = 0.935), an optimal yield of 5-HMF (of approximately 38% in relation to the cellulosic fraction content in the PF-SBP) at a temperature of 192.5 °C and a holding time of about 51.2 min. 5-HMF was successfully isolated from the reaction mixture using the liquid–liquid extraction method. The results are suitable for industrial upscaling and may become an incentive to introduce a new, environmentally friendly, uncomplicated, and efficient waste treatment method. The method would be used to treat products from the sugar refining industry, the treatment of which has proven to be problematic until now.

The high and increasing environmental concern about chemical surfactants triggers attention to more eco-friendly compounds, which are capable of presenting low toxicity and biodegradable nature. This study has evaluated the emulsifying potential of broths obtained from production of rhamnolipids by Pseudomonas aeruginosa AP 029/GLVIIA using different agro-industrial wastes as carbon source, and the influence of using produced water in the culture medium then acting as an inducer. There were used residues of coconut, cashew, sugar cane, carnauba, and moringa seeds. These materials were chemically characterized and used in the production of biosurfactant broths. The emulsifying activity and the surface tension were used as indirect analysis for determining the production of rhamnolipids on biosurfactant broth. For coconut and cashew residues the pH emulsion was observed along time at different temperatures such as 4ºC, 25ºC and 40ºC The emulsification index of all broths were assessed with and without presence of produced water in the culture medium and has indicated the stability of the emulsion along time. Coconut and cashew residues showed a better stability of oil/water emulsion than the other ones, evidencing their potential surfactants. The lowest surface tension about 40 N/m and the highest contact angle (approximately 69 o) were observed for the coconut residue.

Increased water pollution due to industrial, household, and agricultural waste has triggered the need for environmentally friendly technologies for water purification. Eco-enzyme, a solution fermented from various kinds of fruit and vegetable kitchen waste with the addition of sugar and water is recognized to have anti-bacterial and anti-fungal properties effective in decomposing toxic substances and improving water quality. Utilization of waste enzymes is emerging as a viable strategy to treat contaminated water as well as organic fertilizer in the cultivation of family medicinal plants. This training activity on eco-enzyme making and pouring was carried out in the framework of community service activities and the 2024 eco-enzyme festival. Training on making eco-enzymes was carried out using socialization and demonstration methods. Then the finished eco-enzymes were poured into the river behind the campus of 'Aisyiyah University Yogyakarta and watered in the cultivation of Family Medicinal Plants in Sidoagung village, Godean sub-district, Sleman. Based on the evaluation of the activity, participants were very enthusiastic about understanding new knowledge and were able to practice the results of making eco-enzymes. In addition to creating a clean environment, pouring eco-enzymes into the river reduces the contamination of pollutants. In addition, the application of eco-enzymes to the cultivation of family medicinal plants can function as a liquid organic fertilizer that fertilizes the soil and optimizes plant growth.

Higher aquatic plants (HAP) provide more effective tertiary wastewater treatment in biological ponds. They also accelerate the clean-up process with simultaneous increase of hydraulic loading. There was observed not only high removal efficiency for domestic organics, but also for various universal pollutants such as oil, synthetic surface active substances and phenols. Our findings have demonstrated that HAP stabilization ponds may be used successfully for industrial waste water treatment. We have also shown it expedient to apply the method in biological, biochemical and vitamin production plants and sugar refineries. HAP of reed, cane and rush proved to be the most effective plants to use.

Carbon dioxide (CO2) is a gas which causes both impact to atmosphere (one of greenhouse gases) and decrease heating value of gaseous fuel (such as natural gas, biogas, landfill and sewage gas). Hence, there are many investigations to find solutions for gas treatment and carbon dioxide absorption from researchers. Catalyst or synthesized materials is to optimize processes of CO2 treatment and absorption to obtain the best benefit for factories and community. This study utilized industrial wastes of red mud and bagasse in combination with bentonite to synthesis the novel material (absorbent) responding requirements for the process of gas treatment. More specially, raw materials are impacting negatively on the environment. In which, red mud is solid waste of Bayer process from bauxite mining which is being the hard problem to have solutions for its management and utilization and bagasse is industrial waste of sugar factories. Wet pressing method was applied to form the absorbent samples by mixing red mud, bagasse, bentonite, and water in mixtures. The samples were put in furnace for heating process at 300°C for 2 hours. The final samples were characterized for microstructure using X-ray diffraction (XRD) and fourier transform infrared spectroscopy (FTIR). And then the absorbents were tested for gas absorption capacity of carbon dioxide. The results showed a potential application of the novel absorbent materials for gas treatment.

The biosynthesis of sugar esters, molecules with biosurfactant properties, can occur through the esterification of sugars with fatty acids by enzymatic catalysis. An alternative to reduce the impact of raw materials on the final cost of biosurfactant production and reuse industrial waste is to use residues from vegetable oil industries as source of FFA (Free Fatty Acid, such as oleic acid) and lignocellulosic residues of 2G ethanol as source of sugar (xylose). In this scenario, the present work aimed to model the production process of biosurfactants via heterogeneous biocatalysis by lipase, using oleic acid and xylose. Product separation and purification was performed using a sequence of precipitations (by adding ethanol, water and methyl ethyl ketone). Simulation was performed using the equation-oriented software EMSO (Environment for Modeling, Simulation and Optimization), which is CAPE-OPEN compliant. The percentage of biosurfactants in the product was around 86%, with recovery of 88% in the purification. Regarding the study of energy expenditure, it was observed a value of -604.1 kW of heat associated with cooling and a value of 137.6 kW associated with heating. Developed mathematical models successfully described the process. The initial economic analysis of the process indicates a minimum biosurfactant selling price of US$72.37/kg.

The increasing industrial waste was caused problems for the environment. Bagasse is a solid waste produced from the sugar industry. Vinasse is bioethanol industry liquid waste from molasses which contains much nutrients. The vinasse and bagasse in this study was developed into biochar. This study aimed to determine the effect of vinasse addition on biochar characteristics. The yield and characteristics of the biochar were then compared. Based on gravimetric, pH, and SEM-EDX analysis, the result indicated that adding vinasse to the biochar was increasing yield, water content and ash content, lowering pH, and tend to increase nutrient levels (carbon, nitrogen, and potassium). The biochar produced from bagasse and vinasse by pyrolysis had a yield of 6.682-9.406%; water content of 7.0-8.2%; ash content of 4.8-13.6%; at pH 8.4-88; carbon content (C) of 65.07-80.88%; nitrogen (N) content of 2.06-8.66%; and potassium (K) levels of 0.00-2.15%, while phosphorus (P) levels were not detected in SEM-EDX analysis. Based on the consideration of the highest levels of nitrogen and potassium elements needed by plants, the optimum biochar was obtained from bagasse with a vinasse of 7.5%.

Globally organic wastes are generated from fruits, vegetables, and their peels. It is mostly decomposed in landfills or by composting methods. Food processing industries, vegetable markets, and restaurants produce a huge amount of organic waste daily, generally disposed of in the environment or composted. Producing an eco-enzyme from organic kitchen waste was an innovative solution for domestic waste pollution. It is an enzyme solution obtained from an organic waste substance that contains organic acids, enzymes, and mineral salts. It is produced by performing a simple batch fermentation that involves a mixture of brown sugar, fruit or vegetable waste, and water in the ratio of 1:3:10. Two types of the eco-enzyme were produced by a fermentation process using vegetable and fruit peels for about 90 days involving Saccharomyces cerevisiae. The ultimate liquid or enzyme obtained was brown. Eco-enzyme 1 from (Cucurbita maxima) contained hydrolytic enzymes like amylase and lipase. The microbial diversity was observed, and bacteria like Yersinia sp., Bacillus sp., and fungi like Trichoderma sp. and Penicillium sp. No enzymes and microorganisms were observed in Eco-enzyme 2 (Citron). Eco-enzyme 1 with 50% dilution effectively reduced various parameters like BOD, COD, TDS, Nitrate, Nitrite, and Ammonium in the effluent. Also, it promoted plant growth within 10 days compared to the control. Therefore, the present study outlines how the eco-enzyme could be used to treat industrial effluent cost-effectively and environmentally friendly.

The advancement of an environmentally friendly setting is complex due to the significant carbon footprint of cement, substantial construction and demolition waste, and large quantities of industrial waste wastewater. This study aims to increase building sustainability by analyzing the long-term durability of recycled aggregate geopolymer concrete (RGC) manufactured using four different wastewaters. To evaluate each wastewater’s effect on sulfuric acid resistance and chloride ion migration (CIM) at various curing times, RGC was used in place of fresh water in the tests. The results revealed that, when it came to acid attack, RGC made with fertilizer industry wastewater had the highest mass loss (41% higher compared to control concrete) and CIM (29% higher compared to control concrete). According to statistical studies, using wastewater from textile, fertilizer, and sugar firms did not substantially alter mass loss from acid attack or CIM.
