Pineapple loses its crown: Sainsbury’s sells leafless version to cut waste

Removing leaves will mean they can be replanted or shredded for animal feed and could reduce emissions

The pineapple has been dethroned: Sainsbury’s has announced it will start selling a crownless version of the tropical fruit from Wednesday.

The spiky, green leaves that grow from the top of the plant are a unique feature of the exotic fruit. But, says the supermarket, they are typically thrown away by customers, contributing to up to 700 tonnes of food waste a year.

Food waste: Australian households throw out more than $2,000 of shopping a year

One in three households is wasting the equivalent of a shopping bag full of food each week, according to survey

One in three households is wasting the equivalent of a shopping bag full of food each week, a new study has found, despite food waste costing Australians more than $2,000 each year.

Nearly half of Australian households (42%) said they are throwing away as much food or more than they did this time last year, the study from climate action group Wrap and Mayonnaise brand Hellmans has shown.

Co-op to ditch use-by dates on its yoghurt to cut waste

UK consumers urged to use their judgment rather than chuck away products that are safe to eat

The Co-op is removing use-by dates from its own-brand yoghurt in an attempt to address the problem of millions of pots that are still safe to eat being wasted each year.

Instead, starting next month, the Co-op’s own yoghurts will carry a best-before date, with shoppers encouraged to “use their judgment” to gauge if they are edible. About 42,000 tonnes of yoghurt – £100m worth – is thrown away in British homes each year because it is out of date, according to the food waste charity Wrap. Half are dumped in unopened packs.

Why the ancient art of gleaning is making a comeback across England

Volunteers are picking leftover produce on farms to reduce waste and help food banks

“It’s like a vegetable treasure hunt,” says Jenni Duncan, 54, ankle deep in mud, looking at the rows of cauliflower plants stretching out in front of her as the Cornish drizzle gets heavier by the minute.

This field near Hayle in west Cornwall has already been harvested, but not all the produce met supermarket standards and so some was left unpicked. This is where Duncan and her team of volunteers come in, working down the rows, peeling back the leaves of plants that have been left behind, hoping to find small but perfectly formed cauliflowers still tucked deep inside.

Eat this to save the world! The most sustainable foods – from seaweed to venison

What should we be scoffing if we want to help fight the climate crisis from our kitchens? The question has never been more important or confusing – here is a guide to help you get started

Was ever a word so misused as “sustainable”? “Healthy” comes close, and indeed the two are often bandied around together, in trite “good for you, good for the planet” taglines that often appear on foods which are anything but. The question of what we should eat to help combat climate change and environmental degradation has never been more important – nor so confusing. In July, the government will publish its National Food Strategy, based on a year-long independent review, which should shed some light on the matter. In the meantime, there are some foods which, with caveats, you can scoff with a clear conscience.

“Good eating starts at home, and one of the most important things we can do for the future of the planet is to minimise food miles – so our staples should be foods that can grow perfectly well in this country,” advises Patrick Holden, chief executive of the Sustainable Food Trust. Another basic principle is to do your best to understand the story behind what you’re eating – be it plant or animal: “If you know who produced your food, they are accountable to you, and more likely to care.”

Coronavirus measures could cause global food shortage, UN warns

Exclusive: Protectionist policies and shortage of workers could see problems start within weeks

Protectionist measures by national governments during the coronavirus crisis could provoke food shortages around the world, the UN’s food body has warned.

Harvests have been good and the outlook for staple crops is promising, but a shortage of field workers brought on by the virus crisis and a move towards protectionism – tariffs and export bans – mean problems could quickly appear in the coming weeks, Maximo Torero, chief economist of the UN Food and Agriculture Organisation, told the Guardian.

From no recycling to zero waste: how Ljubljana rethought its rubbish

Fifteen years ago, all the Slovenian capital’s waste went to landfill, but by 2025, at least 75% of its rubbish will be recycled. How did the city turn itself around?

Words and photographs by Luka Dakskobler

From the lush green hill you can see Ljubljana, the capital of Slovenia, in the distance. Populations of deer, rabbits and turtles live here. The air is clean and the only signs that we are standing above a 24-metre (79 feet) deep landfill are the methane gas pipes rising from the grass.

Ljubljana is the first European capital to commit to going zero-waste. But fifteen years ago, all of its refuse went straight to landfill. “And that is expensive,” says Nina Sankovič of Voka Snaga, the city’s waste management company. “It takes up space and you’re throwing away resources.”

The study is based on research for Champions 12.3, a group of political, business, NGO and farmers’ leaders from across the world who have united to tackle waste, using data taken from 114 restaurant sites across 12 countries.
