Abstract
The increasing trend of food waste is one of the serious challenges throughout the world. The purpose of this study is to investigate the status of edible oil waste (EOW) from farm to table using the SWOT (strengths, weaknesses, opportunities, and threats) analysis in Iran (2021). First, semi-structured, interviews were conducted with 11 experts in the edible oil industry. Then a cross-sectional study was done on 40 restaurant managers through telephone interviews about the restaurant’s discarded edible oils. Finally, an online study was undertaken among 121 households regarding their waste cooking oil at home. Two categories in five themes with 20 subthemes were explored based on the participant’s perspectives. Lack of up-to-date knowledge and appropriate technology were the main reasons for making waste from farm to factory. EOW is used optimally in other industries. The results showed that 92% of the restaurants sell the EOW for poultry feeds without refinement. The majority of the households [52%] throw EOW in the garbage and 21% dump their discarded oils in the sewage. By SWOT analysis, the challenges of EOW from farm to table were identified. There is no specific policy plan for collecting and recycling EOW. The waste oil used in poultry feed without refinement can enter the human body and the possible oxidation toxicity of this waste can pose public health risks. Policymakers can use the SWOT analysis for setting laws and regulations for EOW to ensure its safe disposal and promote its use for biodiesel to provide a healthy community.
