We throw away more food than we think we do, researchers say
How much food do you throw away
Here are some people who are already pulling their weight when it comes to reducing food waste.
A hearty app-etite
The aptly named Jamie Crummie and his friend Chris Wilson are on a meal-saving mission
If fresh food at shops, cafes, restaurants and street stalls isn't sold, what happens to it? Some donate uneaten sandwiches and the like to charities - but the greater proportion is thrown in the bin.Enter a pair of millennials and their smartphones.Jamie Crummie and his best friend Chris Wilson are behind an app called Too Good To Go, which enables users across the country to buy cut-price meals at the end of trading time.The two entrepreneurs, who met while studying at the University of Leeds, don't see it as just a money-spinner - in fact, Mr Crummie says the ideal goal would be to go out of business because they've raised so much awareness that there is no more food waste."People are already eating at these places, so why not do something awesome at the same time and rescue a meal that would have been wasted?" asks Mr Crummie.

The pair, who teamed up with some like-minded Danish friends to launch the app, have an ambition of eradicating the almost one million tonnes of waste produced by the food and hospitality industry every year - which has a value of more than ?1.5bn."The app is a no-brainer," said Sean Robinson, one of more than 300,000 people to download Too Good To Go since it came to the UK in 2016.Mr Robinson, 30, regularly leaves Sesame Salad Bar in Leeds with a takeaway box full of the shop's leftovers for just ?2.70 - less than half the price of a peak-time portion."It's good for me as well as the customer," said the owner and manager, Ali Felan. "When I don't have to throw food away, it makes me happy. I appreciate the app, I love it."One potential downside is that people have to wait until closing time to eat their meal - although as another user of the app, 26-year-old Jen Wilson, points out, not everybody still has traditional office lunch hours. "The timings are strange but later tends to work better for me."

Joe Halstead, Miha Pipan, Matt McLaren and Fotis Fotiadis came up with the idea for Entomics while at Cambridge University together
A group of scientists believe they could be on the brink of revolutionising the food chain - and that the answer to beating food waste lies (or rather flies) with insects.During their times as undergraduates at the University of Cambridge, Matt McLaren and his friends Joe Halstead, Miha Pipan and Fotis Fotiadis realised there was something special about the larvae of the black soldier fly.The larvae of the insect - Hermetia illucens - have voracious appetites and their digestive systems convert food waste efficiently into useful fats and proteins. In turn, these larvae can be used as cheap, nutrient-rich food on salmon farms.The 10 million tonnes of food we waste each year is linked to the release of millions of litres of greenhouse gas.But the process the young graduates have developed could help reduce these emissions and cut waste. At the moment, the progress of the team's company, Entomics, is restricted by food safety laws.Farmed animals - including salmon - cannot be fed with insects that have eaten manure, even though technically insects can process it.
Could these voracious eaters help us cut greenhouse gas emissions?
"There's a lot of promise but really it's a very difficult regulatory issue," Entomics CEO Mr McLaren explains.The team is therefore using "safer" sources of food for the insects in their research, such as rotting and mouldy vegetables from factories and supermarkets.They have also secured a government grant for ?890,000 to conduct more salmon trials with the University of Stirling."It just shows there's huge promise here," says Mr McLaren, who hopes to find a "truly sustainable animal feed alternative". He thinks there's even a chance humans might one day eat animals that have been fed up with insects that in turn feasted on manure and rotting meat. He said this kind of breakthrough would be a "game changer" in the battle against food waste.

Guy Singh-Watson tries to use every bit of food grown on his farms
Riverford Organic Farmers has gone from being "one man and a wheelbarrow" to supplying organic vegetables to tens of thousands of homes each week.Guy Singh-Watson started growing organic veg on his family farm in Buckfastleigh, Devon, in 1986.A few bumper crops later and the entrepreneur had gone from selling carrots out of the back of his car to supplying Sainsbury's and Waitrose.But something about the business of supplying food started to smell a bit rotten for the eco-friendly farmer."I got very upset seeing our lettuces on the shelves, looking pretty old and tired," the 57-year-old says."They were over-packaged and wasted. You have to grow an excess to meet the demand."So Mr Singh-Watson took matters back into his own hands, cutting ties with supermarkets to slash his waste from an estimated 50% to just 2%.Any leftovers from Riverford's veg box scheme can be used in their restaurants or cafes, or in the staff canteen, and employees can take as much surplus as they like home with them. Food is also donated to local charities and food banks.
Mr Singh-Watson first started selling veg from the back of his car to friends in Devon in the 1990s
The rest is given to the cows on the farms, apart from leeks, garlic and onions, which are composted instead - because if the cows eat them "they make the milk taste a bit funny".But Mr Singh-Watson worries about the sustainability of other parts of his business, which delivers 47,000 veg boxes across England and Wales every week.Competitors such as Amazon Fresh and home delivery from supermarkets mean consumers are becoming impatient with Riverford's delivery policy, which sees customers' postcodes determine the time and date of their delivery.

Is fast delivery a fresh enough idea to tempt customers?
Mr Singh-Watson - who says his staff make up to eight times as many deliveries per mile than supermarkets that have specific time slots - admits he is being "pushed" towards making deliveries more flexible.But the farmer, who sees such a move as an "environmental disaster", said: "We'll hold out as long as we can."
If life gives you apples...

On a cold, rainy day in Brockwell Park, south London, Kath Rosen and her family paint a colourful picture.Brandishing brightly coloured homemade instruments, they are here with a dozen others to take part in the annual "wassail" - an ancient tradition to ensure a good apple harvest."We do lots of banging of pots and make noise to drive the bad spirits out of the tree, and then we pour some cider on the ground and hang bread in the tree to bring the robins, which are associated with fertility," Ms Rosen explains.Behind this ancient ritual is a true food waste warrior.Ms Rosen, 43, is co-CEO of the Orchard Project, a charity dedicated to the creation and restoration of community orchards.
Anyone who donates apples to the Orchard Project gets a third of their fruit back in the form of juice or cider
Perhaps surprisingly, there are plenty in London. But when you consider the definition of an orchard is "a group of at least five fruit and nut trees planted on vigorous rootstocks at low densities in permanent grassland" the situation becomes clearer. These aren't in the rolling hills of the Kent countryside, but nonetheless London has a strong orchard heritage, as evidenced by place names such as Perivale (pear tree valley) and Plumstead (place of plum trees).Last autumn the project harvested seven tonnes of apples from the capital's orchards, using the fruit to make juice and cider at a workshop in Herne Hill.But, as Ms Rosen points out, that was only "the tip of the iceberg""There's so much more fruit in cities which is just left to rot."
