Abstract:

Rapid changes in the field of information technologies, growing production and consumption forced by economic growth lead to growth of waste causing the new challenges to waste management. All these fields are widely analyzed by scientists as separate scientific, technological, environmental or economic problems as well as integrated questions. Waste management is analyzed comprehensively and systematically as well as individual questions of waste generation, waste forecasting, waste storage, and other questions. The information technologies (information systems) are engaged in different stage

Abstract:

The treatment, disposal and management of municipal solid waste strongly depend on the composition and characteristics of municipal solid waste. The Physical composition of MSW and its influencing factors were investigated and analyzed in the residential of Beijing area. The result showed that the composition of MSW in four seasons was similar, and the kitchen was the main composition of MSW, accounting for 69-74% of the total amount of MSW. The average age of families, educational backgrounds, family income and building area have a great influence on the physical proportion of MSW. As the ave

Abstract:

One of today’s major environmental and economic challenges is the fight against both agro- and industrial-waste. Almond production and industrial processing exemplifies this issue, as it generates tons of waste and by-products, with hulls and shells accounting for about 70% of the total fruit’s weight while skins represent about 6% of the shelled kernel. Since the edible kernel, about 23% of the total fruit weight, holds the highest commercial value, there has been growing interest within the scientific community in exploring the potential of these by-products. However, almond by-products cont

The ineffective management of household solid waste (HSW) in most developing cities in Africa including Monrovia has become a major issue threatening the environment and public health. In response to these waste challenges, developed countries have embarked upon major environmental reforms, and have made advances in best practices and sustainable management of their Municipal Solid Waste (MSW). However, in most developing countries like Liberia, such environmental reforms have not been initiated and therefore the situation has become compounded; this is due to several factors impeding the deve

In modern economic conditions, waste management and food security are important areas of sustainable development. Currently, there are many technologies for organic waste recycling. One common method of processing is aerobic fermentation. Food waste is difficult to process due to its physicochemical and organoleptic characteristics, unstable composition, high moisture, and various pH values. This significantly limits the choice of processing technologies. One way to improve efficiency is by combining different types of waste.

Abstract:

Composting is an environmentally friendly treatment technology that recycles and sanitizes organic solid waste. This study aimed to assess the evolution of nutrients, maturity, and microbial communities during the composting of different plant-derived wastes. The composting process was conducted over 49 days using three types of plant-derived waste: wheat bran (WB), peanut straw (PS), and poplar leaf litter (PL). This process was examined through physical, chemical, and biological parameters. The results revealed that after 49 days of composting, the three groups experienced significant change

The results of the studies on the justification of technological processes providing recycling of the warehoused ferruginous quartzites of complex composition and waste non-ferrous metals allowing to receive additional commodity products are given. The example of amphibole and biotite varieties of ferruginous quartzites of CMA and tailings of copper-zinc sulphide Ural ores determines the reasons of ineffective use of traditional technology solutions for recycling. The reasons of environmental hazards concerning varieties of technogenic mineral substances to the environment are identified. The

A grouting material pressure effect simulation device (FSD) was used to study the performance of grout considering grouting pressure, slurry rheology, clay ash, slurry concentration and particle size composition of waste stone powder (FSD influencing factors). After the effect of filter pressing, the alkaline environment of the slurry became stronger, the number of active particles increased, and the CaCO3 and clay crystals were fully agglomerate, and the degree of crystallization increased. The cation exchange capacity increased, and the formation of calcium-silicon-aluminum matrix phase and

Abstract:

Machining operations of cast parts usually generate considerable amounts of waste in the form of chips (usually 3–5% of the casting weight). Traditionally, swarf is sold to scrapers and remelters, but this option is quite expensive because the selling price is roughly 30% of the acquisition price of the commercial 2nd melt raw material. For most aluminium foundries that incorporate machining operations in their products, reusing aluminium chips as raw material for the melting stocks is perhaps the best option as waste management policy in what concerns to economical and technical aspects.

Abstract:

Kiwifruit seeds are usually discarded as waste in the kiwifruit processing industry. However, kiwifruit seeds are rich in oil, which implies their value as a potential resource. Therefore, three-phase partitioning (TPP) using ammonium sulfate and n-butanol has been developed to extract kiwifruit seed oil (KSO) from discarded kiwifruit seeds. The factors influencing the extraction process have been investigated. The highest extraction yield of 36.06% for KSO was obtained under the following conditions: an extraction time of 18 h, a liquid-solid ratio of 4:1, an amount of ammonium sulfate of 28.

Each food category has a unique composition, responsible for its chemical and physical attributes, which directly influences the stability of powdered products. The drying method used is essential to obtain the desired characteristics of the powdered food, and the choice of each technology can provide unique morphological properties regarding size, shape, and density, among other factors. Furthermore, rehydration properties must also be investigated,

Municipal Solid Waste (MSW) disposal is among the most crucial environmental issues for both developed and developing nations. Landfilling is the most universally applied methods of waste disposal because it's inexpensive and relatively easy. As MSW degrades anaerobically in landfills, it generates a combination of gases called landfill gas (LFG), which is mostly methane (45–60%) and carbon dioxide (40–60%), along with traces of VOCs, oxygen, nitrogen, and hydrogen sulfide. Methane, with more than 25 times the greenhouse warming potential of CO₂ over 100 years, is a serious environmental and p
