AbstractObjectiveSupply of essential n-3 PUFA is limited worldwide. While fish-oil supplementation effectively improves n-3 PUFA status, it may not be a sustainable intervention. The use of α-linolenic acid (ALA)-rich cooking oils in the household may be a suitable alternative but its effect on PUFA status is unclear. We aimed to compare the effect of providing families with soyabean oil, an ALA-rich cooking oil, v. sunflower oil on whole-blood PUFA levels of children aged 11–18 years.DesignIn a randomized, masked, parallel trial, we assigned families to receive a one-month supply of either soyabean or sunflower oil. Fatty acid concentrations were quantified in whole-blood samples obtained from the children before and at the end of the intervention. Changes in fatty acids were compared between treatment arms with use of linear regression for repeated measures.SubjectsSixty low- and middle-income families.SettingBogotá, Colombia.ResultsSoyabean oil significantly increased ALA concentrations by 0·05 percentage points of total serum fatty acids whereas sunflower oil decreased them by 0·12 percentage points (soyabean v. sunflower oil effect=0·17; 95 % CI 0·11, 0·24). Concentrations of both n-3 and n-6 very-long-chain PUFA, including docosapentaenoic acid, DHA, dihomo-γ-linolenic acid and arachidonic acid, increased significantly in both intervention arms. Levels of oleic acid and palmitic acid decreased, irrespective of oil assignment. Total energy or energy intake from saturated fat did not change.ConclusionsReplacing cooking oils at the household level is an effective intervention to improve essential PUFA status of children.

Full textAbstract:
Minyak jelantah (mijel) is known in Indonesia as waste cooking oil. Even though it is a waste, mijel is still used by consumers for savings. The problem is, if it is used repeatedly more than three times, mijel can cause health problems. In addition to health hazards, if discharged through water channels, it can cause environmental pollution. Lack of public knowledge about the dangers of using the mijel in the end will have a negative impact. To educate the public about the health-risks of using mijel, we held a short training for housewives in Kelurahan Tanjung Agung, Bandar Lampung on July 22, 2020. This training provided the targeted housewives with the knowledge and skills to process the waste cooking oil into laundry soap. The purpose of this activity was to educate and provide training to the community, especially PKK women who interact directly with the use of mijel, about the dangers of mijel and how to manage it. PKK women who participated in the training seemed interested and understood the explanation described, this can be seen from the increase in the average pretest score from 55.7 to 81.3 at posttest. The benefits obtained by the participants are: 1) Understanding that using mijel more than three times can cause health problems for consumers. 2) Processing of waste cooking oil to laundry soap can reduce pollution in the aquatic environment.3) Laundry soap made from waste cooking oil can be a source of family income.

In this study, the machine vision and artificial intelligence algorithms were used to rapidly check the degree of cooking of foods and avoid the over-cooking of foods. Using a smart induction cooker for heating, the image processing program automatically recognizes the color of the food before and after cooking. The new cooking parameters were used to identify the cooking conditions of the food when it is undercooked, cooked, and overcooked. In the research, the camera was used in combination with the software for development, and the real-time image processing technology was used to obtain the information of the color of the food, and through calculation parameters, the cooking status of the food was monitored. In the second year, using the color space conversion, a novel algorithm, and artificial intelligence, the foreground segmentation was used to separate the vegetables from the background, and the cooking ripeness, cooking unevenness, oil glossiness, and sauce absorption were calculated. The image color difference and the distribution were used to judge the cooking conditions of the food, so that the cooking system can identify whether or not to adopt partial tumbling, or to end a cooking operation. A novel artificial intelligence algorithm is used in the relative field, and the error rate can be reduced to 3%. This work will significantly help researchers working in the advanced cooking devices.

Full textAbstract:
Until now, used cooking oil (jelantah) has not been utilized optimally. This study seeks to convert this waste into biodiesel. Used cooking oil usually contains high concentration of free fatty acids which can be converted into methyl esters through trans-esterification by methanol. This effort is in line with the increasing need for renewable energy sources. Because the waste still contains high concentrations of free fatty acids, it is necessary to think about the right process and catalyst in converting it as biodiesel. One heterogeneous catalyst that is thought to excel in biodiesel production is ferrite-based nanocomposites, namely CaO@CoFe2O4 nanoparticles. The advantages of this catalyst are: it has high reactivity, thermal and chemical stability, and can be drawn by magnetic fields. This last property facilitates the catalyst isolation at the end of the process for recycling purposes. The catalytic power is expected to increase through impregnation with alkaline earth metal oxides which have a relatively high basicity, namely CaO. The purpose of this study was to synthesize and to characterize CaO@CoFe2O4, then to study its potential catalytic in biodiesel production from used cooking oil in various weight percent of catalyst. The main steps include: (1) synthesis of CoFe2O4 by coprecipitation; (2) Impregnation of CaO into CoFe2O4 and converted to CaO@CoFe2O4; (3) Characterization of the synthesized material by XRD, BET, and SEM/EDX; (4) application of CaO@CoFe2O4 in biodiesel production from used cooking oil; (5) characterization of biodiesel produced by viscosity measurement, yield and GC-MS analysis results. Based on the results of XRD and SEM/EDX analysis, the CaO@ CoFe2O4 catalyst has been successfully synthesized. Under optimal conditions, the yield of methyl ester produced with the addition of 2% of catalyst was 80.62%.

In the present study storage conditions ensuring better stability of Soybean oil over a period of 180 days were investigated. The study was carried out on 12 samples (4x3) of three brands namely brand A, B and C. After periodic interval of time ‘acid value’ and ‘peroxide value’ for each sample were determined. The result showed that in every case, darkness decreased degradation in oil over the normal condition over the period of experiments. Results were expressed in terms of acid value and peroxide value. For example peroxide values for samples of brand A stored under normal condition and in the dark were 0.88 on first day where the value came up to 128.64 and 33.3 at the end of 180 days respectively. The trend remained the same for the samples of brand B and brand C. In this study an attempt was made to decrease autooxidation in oils when vitamin E was added (1 ml of 200IU d-α-tocopherol per 100 ml of oil). Samples with and without vitamin E were stored under normal condition and in the dark. Results were expressed in terms of peroxide values. Results failed to show a clear trend of decreasing auto oxidation at the end of 180 days irrespective of the nature of storing condition.

Waste cooking oil (WCO) is one of the economical and easiest sources for biodiesel production. The use of WCO in diesel engine is sustainable if they can perform similarly to diesel fuel. Therefore, this paper presents the performance and combustion characteristics of a single cylinder diesel engine fueled with biodiesel from WCO and compared with diesel fuel. In this study, the WCO was blended with diesel fuel at 5% and 10% blending ratio and named as B5 and B10 respectively. The experiment has been conducted at variable engine speed, constant load and at compression ratios of 17.7. The performance parameters that have been analyzed in this experiment were engine power, torque and in-cylinder pressure. In the end, results show that the engine performance of B5 and B10 was slightly similar to diesel fuel and can be used as a diesels substitute.

Resumo: Neste trabalho são analisadas técnicas de produção do biodiesel a partir do óleo residual reciclado, visando a diversificação da matriz energética brasileira e minimização dos impactos ambientas decorrentes do descarte inadequado desses óleos. Antes do início da produção de biodiesel é necessária a realização de um pré-tratamento deste óleo, o que envolve processos de filtragem, secagem e determinação do teor de acidez, seguida de neutralização, pois de acordo com a porcentagem de ácidos graxos livres presentes na matéria-prima é que os métodos para obtenção dos ésteres são adotados. Primeiramente, foram realizados testes laboratoriais em pequena escala para produção de biodiesel, utilizando como matérias prima o óleo residual reciclado e o óleo de soja degomado para efeito comparativo, tendo sido utilizado hidróxido de sódio como catalisador e experimentadas as rotas metílica e etílica, não tendo sido obtidos resultados satisfatórios neste último caso. Em seguida, a produção foi expandida para uma escala semi-piloto, através da utilização de um reator com capacidade de produzir entre 75 e 80 litros de biodiesel por batelada, sendo neste caso utilizado apenas óleo residual reciclado e processo de transesterificação através da rota metílica, tendo o hidróxido de sódio como catalisador. Depois disso, foi feita a caracterização básica do biodiesel produzido, utilizando-se os equipamentos disponíveis, e foram realizados testes comparativos com outros tipos de biodiesel (Comercial, Vegetal e Animal) e frações de misturas (B25, B50, B75 e B100), tendo como base o biodiesel comercial (B5).

Abstract: This study analyzes the technical production of biodiesel from waste oil recycling, aimed at diversifying the Brazilian energy matrix and minimizing the environmental impacts of inadequate disposal of waste oils. Before the production of biodiesel it is necessary to perform a previous treatment of this oil, which involves processes of filtration, drying and determination of acidity, followed by neutralization, because according to the percentage of free fatty acids present in the raw material is that the methods for obtaining the esters are defined. Firstly, laboratory tests were performed on a small scale biodiesel production using raw materials like soybean oil and recycle waste soybean oil for comparison, having been used sodium hydroxide as catalyst and tested methyl and ethyl routes, being no obtained satisfactory results in this last case. Then, the production was expanded to a semi-pilot scale, using a reactor that can produces between 75 and 80 liters of biodiesel per batch, being in which case only used recycle waste oil and the transesterification process using methanol route, with sodium hydroxide as catalyst. After that, a basic characterization of biodiesel had been done, using equipment available, and were conducted comparative tests with other types of biodiesel (commercial, vegetable and animal) and fractions of blends (B25, B50, B75 and B100), with commercial biodiesel like base of comparison (B5). Finally, tests were performed with these fuels in a 6 kVA diesel generator set, varying a resistive load from 0 to 3 kW and determining the specific consumption and temperature of the exhaust gases. Analyzing the results, it was verified that the physical and chemical properties measured are within acceptable limits, with density between 0,871 and 0,910 g/ml, viscosity between 3,9 and 6,1 cSt and flash point between 51 and 183°C,...

Resumo: A produção intensiva e a disposição inadequada dos resíduos sólidos é um problema a ser enfrentado principalmente nos centros urbanos e pode provocar graves prejuízos ao ambiente e à saúde humana. Dentre os vários tipos de resíduos gerados nas cidades encontram-se os óleos e gorduras residuais de frituras (OGR). São inúmeros os danos causados pelo óleo no ambiente, entre eles, a formação de uma película superficial que dificulta a troca gasosa entre o ar e a água e a impermeabilização das raízes de plantas entre outros. Muito embora algumas alternativas de emprego desse óleo já estão sendo utilizadas, a sua utilização na produção de biodiesel aponta benefícios ambientais e econômicos consideráveis. Na década de 1990 começou-se a pesquisar a viabilidade de utilização dos óleos e gorduras residuais como matéria-prima para a produção de biodiesel, porém faz-se necessário a criação de um eficiente sistema de coleta dos OGRs, o que certamente encontra-se distante de nossa realidade atual. Esse trabalho objetiva elaborar uma estratégia para a gestão dos óleos e gorduras residuais de fritura em residências na cidade de Campinas, S.P. Dentre os resultados adquiridos nessa pesquisa estão a quantidade de óleo gerada pelo município, o comportamento da população em relação ao óleo nas diversas classes de renda e um plano logístico de coleta do óleo para o município. Para alcançar estes resultados foram utilizadas metodologias qualitativa e quantitativa
Abstract: Intensive farming and the inadequate disposal of solid waste is a problem to be tackled mainly in urban centers and can cause severe damage to the environment and human health. Among the various types of waste generated in cities are residual cooking oil and frying fat (OGR). This oil in causes an incalculable amount of damage to the environment including the formation of a surface film which hinders the gas exchange between air and water and the sealing of the roots of plants. Although some alternative uses of this oil are already in place, its use in the production of bio-diesel shows considerable environmental and economic benefits. In the 1990s scientists began to research the feasibility of using waste oils and fats as raw material for the production of bio-diesel. However, it is essential that we create an efficient system of collecting OGRs, which certainly is far from our present reality. This work aims to develop a strategy for the management of domestic waste cooking oils and fats in the city of Campinas, SP. Among the results obtained through this research are the amount of oil generated by the municipality, the behavior of the population in relation to residual oil among different social classes and a logistical plan for the collection of domestic residual oil for the municipality. To achieve these results qualitative and quantitative methodologies were used

Full textAbstract:
Biofuels have received considerable attention as a more sustainable solution for heating applications. Used vegetable oil, normally considered a waste product, has been suggested as a possible candidate. Herein we perform a life cycle assessment to determine the environmental impact of using waste vegetable oil as a fuel. We present a cradle to fuel model that includes the following unit processes: soybean farming, soy oil refining, the cooking process, cleaning/drying waste oil, preheating the oil in a centralized heating facility and transportation when required. For soybean farming, national historical data for yields, energy required for machinery, fertilizers (nitrogen, phosphorous and potassium), herbicides, pesticides and nitrous oxide production are considered. In soy oil refining, steam production using natural gas and electricity for machinery are considered inputs. Preprocessing, extraction using hexane and post processing are considered. In order to determine a mass balance for the cooking operation, oil carryout and waste oil removal are estimated. During waste oil processing, oil is filtered and water removed. Data from GREET is used to compute global warming potential (GWP) and energy consumption in terms of cumulative energy demand (CED). Mass allocation is applied to the soy meal produced in refining and oil utilized for cooking. Results are discussed with emphasis on improving sustainability. A comparison is made to traditional fuels, e.g., commercial fuel oil and natural gas. The production of WVO as fuel has significantly less global warming potential but higher cumulative energy consumption than traditional fuels. The study should provide useful information on the sustainability of using waste cooking oil as a fuel for heating.

On April 20, 2010, the Deepwater Horizon oilrig sank in the Gulf of Mexico, resulting in an oil spill of 4.9 million barrels, one of the largest environmental disasters in United States history. In response to this disaster, the X Prize Foundation sponsored the Wendy Schmidt Oil Cleanup X Challenge, with a one million dollar top prize for engineers to develop better ways to clean up oil after an offshore oil spill. Inspired by the oil spill cleanup challenge, a class project was developed for students in a junior-level fluid mechanics course to develop and implement an oil-spill cleanup solution. Students had one semester to design and build an oil spill cleanup device. At the end of the semester final testing took place in a 20-foot long water table, which was filled with water 6 inches deep. Then for each team of 3–4 students 100 mL of cooking oil was dispersed into the water table, and they had 20 minutes to recover as much of the oil as they could. The grading for the project was based in part on the percentage of the oil the students could recover in the allotted time. The students employed a wide range of techniques, including skimmers, scoopers, and absorbers. The students also had to write a report explaining how their model solution in the water table could be scaled up to full-scale use in an actual offshore oil spill.

Full textAbstract:
The use of biodiesel has been widely accepted as an effective solution to reduce greenhouse emissions. The high potential of biodiesel in terms of PM emission reduction may represent an additional motivation for its wide diffusion. This potential is related to the oxygenated nature of biodiesel, leading to a different PM-NOx trade-off. Wide diffusion is also under debate as it may represent a solution to the highly disputed issue of the development of alternative biofuels sources not competing with the food chain. In fact, besides second generation biofuels (e.g. from algae), the transesterification of Waste Cooking Oil (WCO) is another option, that however needs additional insight. In fact, in this case, the effects on particle emissions are still not well assessed, as well as the impact of fuel distillation on engine performance and emissions. In this paper an experimental study on particle emissions of a DEUTZ 4L off-road Diesel engine coupled to a DOC-DPF system is proposed. Experimental data have been gathered at the engine test bench of the University of Rome Tor Vergata, by using baseline fossil fuel (B06) and blends (30% vol) with both distilled and non distilled WCO biodiesel. Data have been acquired with respect to the three most probable engine points referring to the NRTC (Non-Road-Transient-Cycle), upstream and downstream of the AfterTreatment System. Results show that B30 fuels have always lower emission on a mass and number basis, and that distillation process may have an impact especially at high power and torque operation. A slightly better behavior in terms of mass emissions has been observed for the blend with distilled fuel, while a slightly better behavior in terms of particle number has been observed for the blend with non-distilled fuel.

Full textAbstract:
MTU’s HotModule is a High Temperature Molten Carbonate Fuel Cell System. It transfers the chemical energy of the fuel directly to electricity, heat and a useful depleted air with an electrical efficiency in the range of 42 to 52%. It convinces by minimal emissions of contaminants. The produced heat is given by the depleted air at a temperature level of 400 °C; this ensures a multi purpose and valuable utilization of the heat. The HotModule operated with natural gas is demonstrated meanwhile together with our partner Fuel Cell Energy Inc. in approximately 25 field trial plants and reached now a pre-commercial status. It is highly suitable for the utilization of hydrocarboneous gases, such as biogas, sewage gas, coal mine gas, of synthesis gases from thermal gasification processes of different waste material. Such gases are the most important renewable energy resources. In case of a consequent utilization of such gases for Combined Heat and Power Production a contribution of 12% to 15% of stationary consumable energy consumption can be reached. Even lean gases will be converted with high efficiency to electrical power and high exergetic heat. These characteristics recommend the HotModule for applications using the big potential of regenerative and secondary fuels with all their advantages in decentralized consumable energy supply, reduction of dependence on primary energy imports and reduction of greenhouse gas and other contaminants emission. MTU started recently a HotModule fed by methanol from waste material together with BEWAG in Berlin and many experimental work concerning applications with biogas and sewage gas has been performed with promising results. Due to the high electrical efficiency the HotModule saves about 1/3 of CO2 emission in comparison to conventional “prime movers”. If fuels are used, which are originated from renewable sources like biomass via fermentation or gasification, the balance of CO2 is zero within a suitable short period (in comparison to coal, natural gas and oil, where this period is some millions of years). The advantage of the Carbonate Fuel Cell HotModule is, that these fuel gases from the renewable sources can be used with the high performance and efficiency of the HotModule, even they are low caloric gases, which decline the electric efficiency of conventional prime movers significantly. The products of the HotModule are: • Electricity: DC for telecommunication and IT - AC to grid or to stand alone networks - Applications for uninterruptible power supply. • Premium Heat: Heat from HotModule is available in form of the depleted air at a high temperature. This high exergetic heat is valuable for steam production, industrial production processes as well as for many other processes e. g. in hospitals, in the food industry, in greenhouse farming. It can also be used in cascades of steam production for additional electricity generation via steam turbines, medium temperature processes like drying, cooking, and at the low temperature end for water heating and space heating and — may be — pool heating. • Cooling Power: Another important heat utilization is the production of cooling power for air conditioning and food storage facilities by thermal driven cooling systems, e. g. absorption chillers or steam injection chillers with the overlapping of the required energy amounts over the year: Cooling in summer, heating in winter. This leads to a thermal full power operation of the HotModule all over the year decreasing the pay back period of such equipment. • Fertilizing atmosphere: The depleted air consists of nitrogen, a small amount of oxygen, lots of water vapour and a substantial amount of CO2 (in the range of 5%vol). No contaminants, no toxic ingredients, no other loads. Mixed with fresh air, this depleted air is a most valuable atmosphere for greenhouse farming: Plants need the right temperature, the CO2-contents increase the growing rate of the plants (e. g. tomatoes need an average of 2%vol of CO2 in atmosphere for optimal growing; CO2-fertilizer) and the high water vapour content saves humidification water.
