Synopsis (short abstract) Food waste (FW) is a key challenge on the sustainable development agenda of countries worldwide. The lack of FW data and insights from its analysis about quantities, causes, and characteristics is a significant obstacle in implementing adequate reduction and prevention interventions for different sectors. The primary purpose of the case studies was to review FW prevention, reduction, and management initiatives. Lessons and best practices that enable and facilitate solutions were identified. Nine case studies were conducted targeting five sectors: food services (one restaurant and one hotel), wholesale markets (one fruits and vegetables wholesale market), retailers (one retail market, one retail shop, and one supermarket), caterers (one hospital), and households (five middle- and five high-income households). The case studies consisted of a FW audit that measured the amounts generated from various processes and identified drivers/causes and current best practices. Quantification involved physical separation, weighing, and categorizing the different food components. The separation classified quantities into edible and inedible portions. The study also focused on assessing the environmental and socio impacts, based on assessed and categorized FW quantities. FW is a complex phenomenon where the amount, causes and consequences are contextually different. It is not easy to compare and contrast country-level data and the individual actors in the same country. Therefore, the case study approach has been used in many FW-related studies. Multiple case studies can be expensive and time-consuming to implement. Under this study, we analyzed nine case studies targeting five sectors: food services (four restaurants, a dessert shop and one hotel), wholesale markets (one fruit and vegetable market ), retail markets (one supermarket, one fruit and vegetable retailer, one Dedicated Economic Center), caterers/institutional canteens (one hospital) and households (five middle-income households and five low-income households). Entities were selected based on willingness to participate and an actual FW reduction need.

    Governance analysis for urban wholesale to households food waste prevention and reduction in Sri Lanka 2022

    This report explores and analyses the governance framework (i.e. policies, laws, and regulations) relevant to urban food waste (FW) prevention and reduction in the wholesale, retail, hospitality (restaurants, hotels), food services (schools, hospitals), and households in Sri Lanka. The project "Innovative approaches to reduce, recycle and reuse food waste in urban Sri Lanka" was implemented from June 2019 to August 2021 under the oversight of the Ministry of Urban Development and Housing and in collaboration with the Food and Agriculture Organization of the United Nations (FAO) and the International Water Management Institute (IWMI). Sri Lanka generates around 7 000 tonnes of solid waste per day. From the total solid waste generated, approximately 65–66 percent, by weight, is organic waste. The proportion of food waste (FW) generated in a local authority (LA) area ranges from 50–69 percent of the total waste with an average of 56.56 percent. According to this average value, the estimated total FW generated in the country is around 3 955 tonnes per day. The country faces many challenges in tackling the FW issue also due to gaps in governance. Governance analysis allows a comprehensive understanding of state and non-state challenges and solutions towards FW prevention and reduction. Currently, the governance framework for food safety and quality and (bio-)waste management is under the umbrella of the central government, provincial council (PC), and local authorities (LAs). Additionally, several central and provincial government agencies perform tasks related to (bio-)waste management. Under the 13th amendment made to the constitution of 1987, LAs are under the purview of PCs. The PCs are responsible to help and guide the LAs in the execution of waste and sanitation-related activities. The PCs are empowered to make all decisions on capacity building, resource allocation, adoption of provincial-level policies, and establishing appropriate institutional arrangements to handle the delegated tasks of waste management.

    Sustainable Development Goal (SDG) 12.3 of the UN 2030 Agenda calls for halving per capita global food waste (FW) from retail to households. Food waste (FW) prevention and reduction play a major role in ensuring the sustainability of food systems as well as effective Solid Waste Management (SWM). A coherent, coordinated, and complementary approach to quantification causes identification, and scaling up feasible solutions is necessary. Awareness-raising and capacity development for food supply chain actors, the public sector, and civil society organizations is required for successful interventions. The Project Innovative approaches to reduce, recycle and reuse FW in urban Sri Lanka was implemented under the oversight of the Ministry of Urban Development, and Housing in collaboration with the Food and Agriculture Organization of the United Nations (FAO) and the International Water Management Institute (IWMI) from June 2019 to August 2021. The project produced a series of reports and papers including FAO and IWMI (2021a), FAO and IWMI (2021b), FAO and IWMI (2021c), and FAO and IWMI (2021d) that were used in the awareness creation and capacity development programmes. The major output of the Project was to facilitate knowledge development for and drafting of the Urban Roadmap on FW Prevention, Reduction, Management in Sri Lanka, that includes a comprehensive Action Plan with Monitoring and Evaluation criteria. The objective of this report is to summarize the proceedings of the consultations and sensitization sessions conducted from June 2019 to June 2021.

    Quantitative analysis of food waste from wholesale to households in Colombo, Sri Lanka 2023

    Currently, in Sri Lanka, strategies to address FW prevention and reduction are being considered by different state and non-state stakeholders. However, in the current scenario, solutions for FW are mostly addressing (bio-)waste management. Quantifying FW is of paramount importance in understanding the magnitude and socio-economic as well as environmental impacts of the problem. A good understanding of the availability and quality of FW data is a prerequisite for tracking progress on reduction targets, analyzing environmental impacts, and exploring mitigation strategies for FLW (Xue et al., 2019). FW quantification aims at creating a robust evidence base for developing strategies, action plans, and policies towards FW prevention, reduction, and management as well as guide prioritization of actions, evaluation of solutions, and monitoring progress (CEC, 2019).
