Supermarket food promotions do not contribute to household waste, according to the British Retail Consortium (BRC). Offers on food such as three for two or buy one get one free (BOGOF) are preventing customers from wasting food. A spokesman said: Charging consumers more for food in order to reduce waste seems a rather dubious approach. Price promotions dont contribute to waste, they actually prevent it by encouraging consumers to purchase and use perishable products. The supply of fresh fruit and vegetables isnt turned on and off like a tap. Supermarkets make orders and farmers start growing produce months in advance. When the weather is bad, as it has been this summer, some products, like summer fruits, can be more difficult to shift at precisely the time you start to get more of them. Sometimes you have to offer consumers extra incentives to buy. However, according to a recent Waste & Resources Action Programme (WRAP) report, food waste is a big problem in the UK. Its estimates show that we throw away a third of all the food we buy. WRAP suggests that part of the problem are the BOGOF offers, tempting people to buy more than they actually need. WRAP has committed itself to working with retailers and consumers to try to reduce consumer food waste by 100,000 tonnes by March 2008. WRAP will try to do this by launch a new consumer facing food waste campaign this autumn. Supermarket giant Tesco, said that promotions encourage customers to buy fresh fruit and vegetables. A spokesman said: We find promotions like these are well received, particularly by those families on lower incomes as it makes their money go further. It shouldnt be forgotten that many such promotions are on food which can be frozen. The clearly marked sell by dates on our products enable customers to plan the amount of food they need to buy.
