Despite numerous discussions between scholars and policymakers, food waste (FW) remains a great concern. European Union alone discards 88 million tons of edible food annually, and when energy, inputs from technosphere and nature, labour, waste management of edible as well as inedible parts are assessed, it amounts to significant environmental and economic impacts. Additionally, food waste is considered a social problem and a matter of food security. Since food waste is a problem of the whole foodstuff supply chain, a holistic approach for its management must be taken. For this reason, an industrial ecology (IE) concept can provide a systemic approach that might be an interesting solution for tackling issues associated with such a biogenic food waste stream. The application of IE brings novelty to the research, because the IE approach is typically used for heavy industry that is concentrated in close proximity. The idea behind the IE approach is to prevent as much food waste as possible, then exploit homogenous sub-products for value added product (either food product or not), and, eventually, to obtain energy (or value added products) via fermentation and produce organic fertilizers of a great agronomical value. The results of investigation showed that numerous prevention and technological solutions can be applied to reduce environmental impact, and when available practises are coupled with IE elements, it brings the management approach close to natural ones. The key IE elements in the model are dematerialization and industrial symbiosis; however, other elements, such as restructuration of energy systems and policy alignment, are also present. As a result of the model application, an economically sound, zero food waste management could be obtained in a region

The environmental impacts of five waste management scenarios for polylactic acid (PLA)-based bioplastics and food waste were quantified using life cycle assessment. Laboratory experiments have demonstrated the potential for a pretreatment process to accelerate the degradation of bioplastics and were modeled in two of the five scenarios assessed. The five scenarios analyzed in this study were: (1a) Anaerobic digestion (1b) Anaerobic digestion with pretreatment; (2a) Compost; (2a) Compost with pretreatment; (3) Landfill. Results suggested that food waste and pretreated bioplastics disposed of with an anaerobic digester offers life cycle and environmental net total benefits (environmental advantages/offsets) in several areas: ecotoxicity (−81.38 CTUe), eutrophication (0 kg N eq), cumulative energy demand (−1.79 MJ), global warming potential (0.19 kg CO2), and human health non-carcinogenic (−2.52 CTuh). Normalized results across all impact categories show that anaerobically digesting food waste and bioplastics offer the most offsets for ecotoxicity, eutrophication, cumulative energy demand and non-carcinogenic. Implications from this study can lead to nutrient and energy recovery from an anaerobic digester that can diversify the types of fertilizers and decrease landfill waste while decreasing dependency on non-renewable technologies. Thus, using anaerobic digestion to manage bioplastics and food waste should be further explored as a viable and sustainable solution for waste management.

Socio Demographic Factors

Most local authorities in Malaysia spent as much as 60-70 percent of their annual budget to dispose food waste together with other municipal solid wastes to landfills. It is time for Malaysians to start reducing food waste through sustainable method, as it is becoming an uphill task to manage food wastes generated in Malaysia. When households reduce the amount of food waste generated in a sustainable way, it could help reduce cost, and other related bills for households, and as well in running their other daily activities. The main objective of this study is to assess how sociodemographic factors of households in Selangor and Terengganu influence their behaviour towards participation in sustainable food wastes management program. The study applied purposive nonrandom sampling consisting of 333 respondents, 257 were from Selangor and 76 from Terengganu. Primary data was collected through structured questionnaire. Descriptive and logistics regression model analysis were used to analyze the data. Findings have shown 48.7 percent of Terengganu respondents spent not more than RM100 on food per week, while Selangor had 41.2 percent within the same period who spent such amount. 35.4 percent of Selangor respondents spent between RM101-200 compared to Terengganu which spent same amount at 30.3 percent within the same periods. The survey shows 43.2 percent of Selangor households disposed 1-3kg food wastes, while Terengganu on the other hand had 51.3 percent who disposed same quantities of food wastes per week. Respondents with higher education, those on government jobs, small family size and ethnicity have significant impacts on the respondents' behaviour towards participation in sustainable food waste management program.

Environmentally Sound

Management of Waste Electric and Electronic Equipment (WEEE also called e-waste) has become an issue of critical importance recently also in the frame of industrial ecology besides waste management per se, mostly due to their content in hazardous materials and the extensive implications of any intervention in a broad industrial spectrum. The effectiveness of any landfill diversion scheme depends on its acceptance by the local community and the industry, as well as adequate funding. This paper presents a contingent valuation approach in order to examine public environmental awareness and to assess the willingness-to-pay (WTP) for the environmentally sound management of WEEE in Greece, based on a suitable, customized and easy-to-comprehend questionnaire. The survey revealed a still relative public ignorance on the subject and a reluctantly limited WTP. The latter is mostly triggered by the fact that respondents believed that associated expenses should be covered either by authorities or manufacturers (protest votes). However, based on the responses of those declaring a positive WTP, the average fee respondents are willing to pay exceeds the current recycling fee. Thus, existing recycling fees could be potentially increased in order to cover additional expenses for the development of infrastructure in areas not currently included in the national WEEE recycling program, as well as to provide the public with a dense network of disposal sites/bins in an effort to boost participation and WEEE recycling rates.

Resource Input

North America is a big consumer and consequently a big producer of waste. For the purpose of this project, we were primarily interested in collecting information in North America, focusing on Quebec primarily. The main research question was risen up during the fieldwork and assistance with the Canadian company. It clearly presents the enterprise readiness for obtaining a smart solution on organic/food waste problem. It is believed, how organic/food waste can be a resource of a high value. There is a capacity of creating a new path, where organic/food waste could become the important as plant/field nutrient supply. The circular approach to organic waste management is urgently needed in a way how the organic waste should be reduced and returned as productive resource input into our economy. The paper presents a new value towards a sustainability process that Canada is building at the moment. It represents the innovative approach, which is highly accepted in some cities in Quebec with the obtained pilot projects and excellent results. This paper is not only a simple research paper, but it is also the very important original innovative document which can be highly used on the level of each municipality, region and federal level.
