Showing results for: Food waste/surplus food
This book presents case studies and guidance on extracting high-value compounds from waste and by-products from foods such as dairy, meat, sweet potato, cereals and olive oil.
This report from the UK charity Waste and Resources Action Programme (WRAP) provides the latest estimates for food losses and food waste in primary production (i.e. on farms) in the UK. It finds that 3% of food harvested is wasted at the farm stage (sent to waste treatment such as composting without first being used for another purpose, or left in the field) and 4% is surplus (material intended for food uses that ends up being redistributed to people, fed to animals or used for other purposes), making a total of 7%.
This report from the Food and Land Use Coalition proposes ten critical transitions that could enable the food system to provide healthy diets for nine billion people by 2050 while also protecting the climate and biodiversity. The transitions are estimated to provide over 15 times more social benefit than their investment cost, which is likely to be less than 0.5% of global GDP.
This paper quantifies the carbon emissions, water use and land use associated with the consumption of food excess to requirements, on the basis that overnutrition has sometimes been classified as a form of food waste. It finds high geographical variation in the environmental impacts of so-called excess food consumption, with impacts being an order of magnitude greater in Europe, North America and Oceania than in sub-Saharan Africa.
Over 100 food organisations, including many supermarkets, have signed the “Step up to the Plate” pledge (organised by the UK’s Department for Environment, Food and Rural Affairs) to halve food waste by 2030, support a week of action in November 2019, empower citizens and change their individual habits so as to reduce food waste.
According to this paper, households in the Netherlands wasted 41kg of solid food per person in 2016 - a 15% decline since 2010. Furthermore, 57 litres per person of potable liquids such as coffee, tea and milk are disposed of via the sink or toilet each year. Rice, bread, pasta, vegetables and pastries are among the food types most likely to be wasted (as a percentage of purchased quantity).
This book synthesises the academic literature on sustainable food supply chains and offers quantitative models on topics such as shelf life, vehicle routing and waste management.
This book offers a cross-disciplinary collection of perspectives on the many sustainability issues facing the global food system today. Topics include food insecurity, healthy diets, organic food, food among refugees and food waste management strategies.
Wageningen University and Research has formed a consortium together with several private companies to research the use of co-products and residues from the food sector and industry as animal feed. A particular research focus will be on increasing Europe’s self-sufficiency in feed materials.
This paper calculates the environmental impacts (climate change, acidification, eutrophication, land use, and water use) caused by either making a meal by using a meal kit (which contains pre-portioned ingredients for cooking a meal) or by buying the ingredients from a grocery store.
This book by Darrin Qualman argues that, to avoid the collapse of civilisation, the global economy must reshape its material and energy flows away from linear, extractive patterns towards a circular model. The book includes a chapter on food production.
This policy briefing from EU food waste research project REFRESH outlines policy options for reducing food waste at the consumer level, based on both desktop research and a survey of households in four countries.
This policy briefing from EU food waste research project REFRESH outlines how ‘Voluntary Agreements’ between stakeholders throughout the supply chain can be used to reduce food waste, and makes policy suggestions to favour the creation of such agreements.
This blog post in Foodprint (part of US food advocacy group GRACE Communications) explores how food safety scares and recalls can cause food waste. In addition to the disposal of contaminated food items, other items of the same type are often disposed of to be sure of removing all affected items. New supply chain traceability technologies could reduce the amount of food disposed of during recalls.
This paper provides an assessment of the environmental impacts of converting waste streams from the food industry into products such as fertiliser, pet food, livestock feed or feed additives using the larvae of Hermetia illucens, the black soldier fly.
