Pandemic makes less food waste in the world

Thin Lei Win -

When the coronavirus pandemic forced Rohini Singh to work from her house, she realised the grocery bill was likely to rise since her family of three would be mostly eating at home. She also didn’t want to waste food, with shelves in some supermarkets emptying in the early days of the crisis, and trips to stock up becoming more perilous.

“I think the pandemic made me more conscious about saving money and not wasting (food) if I can help it,” the university professor, who lives in Ohio, said.

To try to achieve both goals, she signed up to Imperfect Foods, which delivers produce and other foods rejected by grocery stores and supermarkets for cosmetic reasons. “Instead of getting thrown out, if (the foods) were to be sent to consumers who don’t mind the bumps and blemishes, it seemed... a way to cut down on waste,” Singh said. Advocates against food waste say the pandemic has made some consumers in rich countries reconsider how much food they bin, a habit they hope will stick even after the health crisis is over.

Rachael Jackson, who runs Eat or Toss — a website that helps people assess if foods such as apples with black spots or sweet potatoes with purple sprouts are still safe to eat — said her traffic tripled between February and May.

“People didn’t want to go out as much, and things they found in their kitchen that normally they would throw away — now they were interested in doing research to find out if it was still okay to eat,” the Washington-based journalist said. Since then, the site’s traffic has neatly followed the US pandemic’s curve, slipping a little when shops and restaurants re-opened and climbing again since July as the virus resurged, Johnson said.

Dana Gunders, executive director of ReFED, a non-profit focused on reducing food waste in the United States, is optimistic pandemic-sparked behaviour changes — such as eating more leftovers and being careful about waste — will last.

“Certainly in the United States this pandemic is stretching out long enough that it is building new habits,” she said. People are likely to continue to eat more at home for the foreseeable future and do more food shopping online, which tends to result in less waste, she said. Before the pandemic, almost a third of the food that makes it to the market was wasted at shops and homes, according to the US Department of Agriculture.

Studies in parts of Europe show food waste declining. A survey of nearly 7,000 people in Belgium, Italy, Portugal and Spain, published on Tuesday by Euroconsumers, a cluster of consumer organisations, found the number of people who said they threw away almost no food doubled to 70 per cent during lockdown. WRAP, a British non-profit focusing on sustainability issues, similarly found in an April survey that households were wasting a third less of four key products — potatoes, bread, chicken and milk — than before the virus lockdown.

Waste figured inched slightly higher in a repeat survey in June, as lockdown eased. Still, the 18 per cent of food purchased that was thrown away in June was lower than the pre-lockdown level of 24 per cent, said Andrew Parry, special advisor for food and drink at WRAP.

“It’s a positive unintended consequence” of the pandemic, he said. “There’s been an increase in the realisation food is precious.”

Climate change concerns are playing an important role too, with more than 80 per cent of people surveyed in June citing this as a worry. However, only 37 per cent said they understand the link between food waste and global warming, Parry said.

With rising food production a major driver of deforestation and a big consumer of fossil fuels for farming, processing and delivery, cutting food waste can significantly cut climate changing emissions, scientists say.

Globally, a third of all food produced — about 1.3 billion tonnes — is lost or wasted along the whole supply chain, according to a 2011 assessment by the United Nations’ Food and Agriculture Organization (FAO).

The UN Environment Programme is expected to put out updated figures on food waste in shops and homes in 2021. Overall, food production accounts for about a quarter of climate changing emissions, according to a 2018 report in the journal Science.

The pandemic has made restaurants more open to tackling food waste to cut costs, said Renata Bade Barajas, CEO and co-founder of Iceland-based start-up GreenBytes, which uses artificial intelligence to predict sales and optimal stock levels.

“Now more than ever, they have to optimise their whole system and cut down unnecessary operational costs,” she said.

Their initial research showed many restaurants in Reykjavik could be throwing away hundreds of kilos of food a month, said Bade Barajas, whose work in the kitchens of restaurants and juice bars during her university studies brought her face-to-face with food waste. “Every day, without fail, you end up throwing away so much food,” she said. “I felt guilty.” — Thomson Reuters Foundation
