Utilization of wastewater from Edible Oil industry, turning waste into valuable products: A review
Trends in Food Science & Technology, 2020Co-Authors: Talha Ahmad, Tarun Belwal, Sudipta Ramola, Rana Muhammad Aadil, Abdullah, Luo Zi-shengAbstract:Abstract Background Increased demand of Edible Oil throughout the world has resulted in establishment of many Edible Oil industries leading to generation of huge amount of wastewater. Wastewater is generated mostly during the processing operations and washing of equipments. This wastewater has high nutrient content, biological oxygen demand (BOD), chemical oxygen demand (COD), lipids (fats, Oil and grease) and organic and inorganic contents, so if disposed untreated it can result in sOil, water and air pollution. Scope and approach This review is aimed to describe different methods used by Edible Oil industries to treat wastewater and their efficiency for removal of pollution. Especially, focuses on different utilizations of wastewater as a resource from Edible Oil industry. Key findings and conclusion Physiochemical (i.e. coagulation/flocculation), biological (i.e aerobic and anaerobic) and electrochemical methods are used for treatment of Edible Oil industry wastewater. These methods can be used alone or in combination for effective treatment Alternatively, utilization of wastewater is the most recent approach which is not only reduce pollution but also lead to the recovery of useful industrial products, such as bioactive compounds, bioplastic, biofuel, biofertilizer, biopesticide, enzymes, single cell proteins and many more. Moreover, bioactive compounds (i.e. polyphenols) can be extracted and used in different food products which leads to generate potential future possibilities for food and agriculture industries.

an analysis of biodiesel fuel from waste Edible Oil in taiwan
Renewable & Sustainable Energy Reviews, 2007Co-Authors: W T Tsai, Chihchung Lin, Chingwei YehAbstract:Abstract Taiwan is a high energy-importing nation with more than 98% of our energy supplied by imported fuels in 2004. The diversification of kinds and sources of primary fuel is becoming vital energy issues in the country. In this regard, biomass energy like biodiesel fuel from waste Edible Oil is thus becoming attractive due to the environmental and energy policies for promoting sustainable development and environmental pollution mitigation in Taiwan. The objective of this paper is to present an analysis of energy utilization from waste Edible Oil for the diesel production in Taiwan. The description in the paper is thus summarized on current status of diesel fuel and Edible Oil supply and consumption, and waste Edible Oils, and then centered on new/revised promotion legislation/regulations especially concerning the waste-to-biodiesel in the measures of environmental protection and economic/financial incentives. Finally, we survey the first demonstration plant in the production of biodiesel from waste Edible Oil including process description and benefit analysis, which has started to be operated in October 2004 on an industrial scale of 3000 metric tons per year.

Regeneration and reuse waste from an Edible Oil refinery.
Environmental science and pollution research international, 2017Co-Authors: Abdelhamid Boukerroui, Lydia Belhocine, Sonia FerroudjAbstract:A spent bleaching earth (SBE) from an Edible Oil refinery has been regenerated by thermal processing in oven, followed by washing with a cold solution of hydrochloric acid (1M). Optimal regeneration conditions have been controlled by decolorization tests of degummed and neutralized soybean Oil. Optimal values of treatment (temperature 350°C, carbonization time 01 h, and HCl concentration 1M) gave a very efficient material. After bleaching Oil by regenerated spent bleaching earth (RSBE), the chlorophyll-a and β-carotenes contained in crude Edible Oil and observed respectively at 430, 454, and 483 nm, value of λ max, are very much decreased. The results obtained after decolorization of Edible Oil by RSBE material indicate, that, during the process, the bleaching Oil did not undergo any changes in the free fatty acid content. The peroxide value (PV) was reduced from 4.2 to 1.8 meq O2/kg, and the color has been improved (Lovibond color yellow/red: from 50/0.5 to 2.7/0.3, respectively). The RSBE material obtained was characterized by several techniques (FTIR, SEM). The results show that the heat treatment did not affect the mineral structure of RSBE, and the regenerated material recovered its porous structure.

Study on the Decoloration Technology of Waste Edible Oil with Activated Clay
2009 3rd International Conference on Bioinformatics and Biomedical Engineering, 2009Co-Authors: Qi Deng, Qifei Huang, Qunhui Wang, Qi Wang, Pinghe YinAbstract:Given more efficient utilization of waste, the social impact of waste recycling is far-reaching in saving resources and reducing environmental pollution, therefore promoting society development. The sources of waste Edible Oil are very complicated. The color of waste Oil after simple recycling and refining is still dark and with strong smell. The amount of a variety of impurities is relatively huge. The pigment in waste Oil affects its stability, industrial use and further processing. In order to meet the requirements of comprehensive utilization of waste Oil, pre-decoloration is absolutely necessary. Activate clay has been reported to have decoloration effect on waste Edible Oil and this paper discussed the factors which influenced the decoloration rate. The optimum conditions of decoloration were established in this research: concentration of activated clay was 5%; initial temperature of decoloration was 60degC; final temperature of decoloration was 120degC and time of decoloration was 25 min. This result of research could provide appropriate material for the utilization of waste Edible Oil in production of detergent by saponification, save the natural resources and economy cost. At the same time, the "waste" became "available resources".

Study on Saponification Technology of Waste Edible Oil
2009 3rd International Conference on Bioinformatics and Biomedical Engineering, 2009Co-Authors: Qi Deng, Qifei Huang, Qunhui Wang, Pinghe YinAbstract:With rapid economic development, resource shortage and environment pollution have increasingly became a bottleneck in the ongoing development of society. The concept of "cyclic economy" has been proposed to build a resource-saving and environment-friendly society. Under this concept, "waste" should be treated as "misplaced resources". Given more efficient utilization of waste can promote society development. The precursor of waste Edible Oil is natural Oil with main component of glycerol ester. The saponification of glycerol ester could produce glycerol and detergent such as sodium, potassium soap, etc. Therefore, the saponification of waste Edible Oil could be used directly to produce soap and washing powder. Practically, there are problems like long period of reaction time of saponification, incomplete saponification or no saponification at all. This paper studied the method and mechanism of saponification of waste Edible Oil and the factors that influenced the saponification degree by analyzing infrared spectrum of the product. Our experiments showed that the saponification processing reached the optimal configuration with four-hour reaction at the temperature of 100degC, the mass ratio of sodium hydroxide solution to the waste Edible Oil was 1:2 and the concentration of sodium hydroxide was 30%. The research of this paper is far-reaching in saving resources and reducing environmental pollution.
