Knowledge for better food systems

Showing results for: Waste and resource use

Food waste is common in both developing and developed countries. Estimates of the scale of waste and loss are between 30% to 40% of all food produced. Waste loss occurs during production, distribution and at the consumer stage. In richer nations, more food is wasted at the consumer level than in poorer countries: in Europe, an average of 95 kg of food is thrown out by each consumer each year. In developing countries much produce is lost due to a lack of suitable packaging and storage facilities (so called post-harvest losses). According to the FAO, consumers in rich countries waste almost as much food (222 million tonnes) a year as the entire net food production of sub-Saharan Africa (230 million tonnes). Food waste also represents a waste of all the embedded resources involved in producing it (land, water, fossil fuel inputs, agro chemicals) and in this sense is also a source of 'unnecessary' GHG emissions.

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).

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.

Free-range eggs in the Agbogbloshie slum in Ghana are contaminated with some of the highest levels ever measured (in eggs) of certain toxic substances due to the illegal dumping of electronic waste from Europe, according to this report from Swedish non-profit IPEN and US non-profit Basel Action Network.

This paper maps the potential for different subnational, national, or regional areas to reduce their agricultural dependence on imported phosphorus fertiliser by recycling manure or urban waste (including both human excreta and household and industrial wastes).

FCRN member Tom Quested of resource efficiency organisation WRAP Global recommends the REFRESH Community of Experts, which is an online platform to find and share information (such as best practices) on food waste prevention.

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 paper traces mass, energy flows and emissions in the beef, poultry and pork supply chains in Germany (including all emissions from the animal production stages, and emissions from energy use at subsequent stages). It outlines the potential of different strategies to reduce consumption-based emissions. It finds that the greatest emissions reductions could come from dietary change, i.e. replacing some meat consumption with consumption of soybeans and nuts, or replacing some meat consumption with offal consumption.

8 April 2019

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.

26 March 2019

In this paper, FCRN members Christian Reynolds and Tom Quested review the effectiveness of different consumption-stage measures to reduce food waste. Examples of successful interventions include serving food on smaller plates (which can reduce food waste by up to 57%) and changing school nutritional guidelines (which reduced waste of vegetables by 28% because fewer students selected vegetables and those who did select vegetables ate more of them).

20 March 2019

This report from the UK’s Sustainable Restaurant Association reviews the current state of sustainability in the UK food service sector. The three main challenges it identifies are reducing the amount of meat on menus, reducing food waste, and using less single-use plastic packaging.

This booklet, by FCRN member Imke de Boer, sets out the scientific basis for the 2018 Mansholt lecture by Louise Fresco, President of the Wageningen University & Research Executive Board. The lecture discussed how the concept of circularity can be applied to agricultural production.

29 January 2019

This report from the Ellen MacArthur Foundation outlines three ways in which cities can promote a circular food economy: source food grown regeneratively and (when appropriate) locally; reduce waste and use by-products; and design and market healthier food.

15 January 2019

The UK government has set out a waste and resources strategy for England, aiming to eliminate all avoidable waste by 2050 and promote a circular economy. Proposed measures include taxing plastic that contains less than 30% recycled material and providing food waste collection to all householders and relevant businesses.

The World Resources Institute has published a new report outlining solutions for feeding 10 billion people without increasing emissions, fueling deforestation or exacerbating poverty.
