‘We throw away half our food’

throwaway food afp AFP A man places bruised fruit in a bin at a market in New York City. A new London-based study byThe Institution of Mechanical Engineers found that as much as half of the food produced in the world ends up going to waste.

London - Up to half the food we buy from supermarkets goes in the bin despite much of it being perfectly edible, a report has revealed.

Experts say a throwaway consumer culture that undervalues food is behind the colossal waste.

They blame confusion over sell-by dates and retailers’ “buy one, get one free” offers that tempt shoppers into buying more than they need.

Across Britain seven million tons of food, worth more than £10-billion, is thrown away annually – costing the average household £480 (about R6 000) each year.

Of the food binned by families, from fresh fruit and veg to tinned and packet produce, £1 billion worth is still within its sell-by date and good to eat.

The report, by the Institution of Mechanical Engineers, says that up to three quarters of vegetables grown in Britain ends up never being eaten, with large amounts being left in the field or rejected by supermarkets for being too ugly.

Author Dr Tim Fox, head of energy and environment at the IME, said that over a lifetime an average household will throw away up to £24 000 worth of food.

He said: “Between 30 and 50 percent of food bought from supermarkets is thrown away. It gets home from the shops, placed in the cupboard or fridge, and then up to half of that food goes in the bin.

“One of the problems is the way supermarkets retail. Consumers end up buying more produce than they need because of special offers. Many of these items have a limited shelf life, so they end up being thrown away.

“And with much of our fresh fruit being imported from around the globe, it does not have the lifespan of locally produced food because it has already spent days travelling.

“There is also confusion over labelling and sell-by dates, with many people opting to throw away perfectly good food.”

The average British family spends only 11 percent of its budget on food, which explains why it is not valued more highly, the report found.

Dr Fox said: “With the shift away from small shops... to large-scale supermarkets, we have lost the sense of value of food.”

Almost a third of vegetables are never harvested and are ploughed back into the field because of overproduction and for aesthetic reasons, according to the report, Global Food: Waste Not, Want Not.

“Many farmers produce more than is necessary as back-up to meet the strict criteria in the supply agreements set by supermarkets,” said Dr Fox.

With a further 30 percent never making it to the supermarket shelf because they are considered too ugly to be sold, only half a farmer’s crop is likely to be sold.

The misshapen produce is either left to rot in the field, sold off to be added to manufactured products such as soup, used as animal feed, or put in composting.

But, once consumer waste is factored in, up to three-quarter of vegetables never make it on to a family’s plate.

Dr Fox said: “It is remarkable that you get any food to the table at all. Up to 75 percent of the veg grown in the UK doesn’t end up being eaten. That’s the bottom line.

“With a lot of vegetables, it is simply the fact that it just doesn’t look right. The crop is not harvested simply because it will not sell, but apart from appearance they are perfectly edible.

“Although schemes are in place to sell some of this veg in different outlets, not enough is being done to tackle this waste.”

The picture remains the same across the globe, with around half of all food produced – two billion tons worth – lost to waste. But in developing countries the issue is one of storage rather than profligacy.

Others have queried the report’s figures, with the food waste campaigners WRAP saying only one fifth of all the food and drink we buy as consumers ends up unused in the bin.

Food waste expert Emma Marsh said: “Our research has shown that 7.2 million tons of food and drink waste is generated by households in the UK each year. Of this, 4.4 million tons is avoidable food waste. This avoidable food waste has a value of £12-billion per year.”

She said that preparing too much food was one reason for waste, while misunderstanding over labels was another factor.

Andrew Opie, director of food and sustainability at the British Retail Consortium, which represents retailers, said: “Using more of the crop to cut food waste and increase sustainable production is an objective for all retailers. This is how we are exceeding Government targets for food waste.

“It was supermarkets that lobbied Europe to relax strict marketing rules on fruit and veg to allow us to sell more misshapen produce. This has led to an enormous increase in the sale of ‘wonky’ veg.

“We’ll continue to work with growers to use more British produce, cut food waste and give customers great value. It’s a win, win, win.” - Daily Mail
