Food waste is a matter that rarely attracts the same attention as climate change or renewable energy, yet its consequences for communities, the economy, and the environment are profound. Earlier today, a report on Times Radio highlighted the staggering quantities of food that are wasted each year, and recent research confirms that nearly one-third of all food produced globally is discarded. This amounts to an estimated 2.5 billion tonnes annually, corresponding to approximately 40 per cent of food produced for human consumption and resulting in 5.8 trillion meals lost, even as millions of people suffer from hunger.
 
In the United Kingdom, approximately 9.5 million tonnes of food are thrown away each year, a volume that could feed roughly 30 million people, while 8.4 million live in food poverty. This disconnect reveals a fundamental systemic issue, as a significant share of edible food is consigned to waste rather than redirected to those in need. The economic ramifications are equally alarming, with consumers and households collectively spending nearly £19 billion on wasted food each year and each household losing an average of £470. In addition, food waste in 2022 was responsible for around 18 million tonnes of greenhouse gas emissions, an impact comparable to removing one in every five cars from the road.
 
The problem spans the entire food supply chain. Households generate approximately 70 per cent of the overall food waste – around 6.7 million tonnes per year – with each individual discarding roughly 70 kilograms of food, equivalent to 140 meals, annually. Manufacturers contribute about 16 per cent, while the hospitality and food service industries account for roughly 12 per cent, and the retail sector, although responsible for only about 2 per cent of the waste, sees large supermarkets discarding up to 270,000 tonnes each year.
 
Food waste manifests in various forms across the supply chain. There is plate waste, consisting of unfinished meals or uneaten portions, and food that is discarded after passing its ‘best before’ date or having spoiled from improper storage. Additionally, waste is generated during food preparation from trimmings, peels, and by-products, and perfectly edible items are often rejected by retailers for failing to meet strict cosmetic standards. For instance, bread is one of the most wasted food products in the United Kingdom, with approximately 900,000 tonnes discarded annually, while other commonly wasted items include potatoes, milk, bananas, and salad vegetables. Factors such as overproduction, stringent aesthetic requirements, consumer confusion over date labelling, overbuying, and ineffective storage practices all contribute to this crisis.
 
The consequences of food waste extend beyond financial loss and food insecurity. Wasted food contributes significantly to climate change, not only through the energy expended in production and transportation but also through the greenhouse gases released as it decays in landfills. On a global scale, the loss of 2.5 billion tonnes of food each year represents a squandered resource and a missed opportunity to alleviate hunger.
 
Addressing food waste necessitates a reappraisal of the entire relationship with food, from production and distribution to consumption and disposal. When millions remain in hunger while vast quantities of edible food are discarded, every decision made at home or within business operations is vital to building a more sustainable and equitable food system. Reducing food waste not only conserves financial resources and mitigates climate change by lowering greenhouse gas emissions, but it also provides an opportunity to nourish communities and protect the planet.
 
To address these challenges at a household level, careful meal planning, purchasing food in smaller quantities, proper storage, and the creative reuse of leftovers can make a substantial difference.
