Instead, dem dey throw amay. Experts talk say food dey waste for both rich and poor countries, but for different reasons.

Elliot Woolley teach sustainable manufacturing for Loughborough University for Britain. E tok for di Global Conference on Sustainable Manufacturing, wey happun earlier dis month for Vietnam.

Mr. Woolley talk say for poor countries, food dey loss for di field or during storage and transportation. E tok say na because food producers for dia no dey efficient. Dem no fit operate well without waste materials, time or energy. But e add say once food dey sell for developing countries, people dey chop everything wey dem buy.

However, people for developed countries dey throway as much as half of di food wey dem buy. For US, big contributors to waste include supersized portions wey customers no fit finish, and "eat as much as you want" offers for restaurants. For UK, over-conservative sell-by dates on labels and two-for-one offers of perishable items dey important, e dey encourage consumers to buy too much food and throway items wey don reach dia sell-by date, but wey still fit chop. And efficient farming methods, transport and storage mean say most of di wastage dey happen through retail and customer behavior. Di British researcher call dis custom "a disgrace".

Elliot Woolley don create smartphone app wey e say dey show users di food wey dem buy and when di food dey almost spoil. E still give information on how people fit combine di foods wey dem get to make food. Di software program dey call "Pantry App".

Mr. Woolley talk say people wey use di app reduce di amount of food wey dem waste by one third. But dis result na from limited experiment -- users only follow dia food use for one week.

Jeremy Bonvoisin na student for di Technical University of Berlin. E attend di recent conference for Vietnam. E talk say one way to solve di problem of wasting food na to persuade people to stop buying too much food for di first place. E say people dey buy more food than dem need because e dey less costly. Dem waste so much food because dem buy pass wetin dem need.

E say di new app fit help those wey already wan change di way dem dey use di food wey dem buy. But e dey also fear say e fit make people waste more food because dem no go dey pay attention to how much dem don buy.``` <response>: 1. Elliot Woolley
