UK's Largest Grocer Takes on Food and Plastic Waste

It's been a green week for Tesco, the UK's largest supermarket.

First, the chain said it would remove "Best before" labels from around 70 pre-packaged fruits and vegetables in an attempt to stop customers from discarding still-edible food, BBC News reported Tuesday.


Then it announced plans to ban all non-recyclable plastics by 2019, The Independent reported Thursday.

Both moves honor pledges Tesco has made to limit its environmental impact. Last year, the store said it would end food waste by March 2018, according to The Independent. The plastics decision comes as part of the UK Plastics Pact that Tesco signed a month ago, in which 40 UK businesses committed to eliminate single-use plastic packaging by 2025, among other goals.

The labeling decision was based on a survey by the National Federation of Women's Institutes (NFWI) that found that less than half of customers surveyed understood what "Best before" labels meant. "Best before" labels indicate that food is still safe after the listed date, but quality might suffer, whereas "Use by" labels indicate that food is actually not safe to eat after the date printed. Seventy percent of customers did understand the "use by" label, according to the NFWI.

"We know some customers may be confused by the difference between 'Best Before' and 'Use By' dates on food and this can lead to perfectly edible items being thrown away before they need to be discarded," Tesco's head of food waste Mark Little said.

He added that produce was being targeted for the change because it was one of the most wasted products.

"Many customers have told us that they assess their fruit and vegetables by the look of the product rather than the 'Best Before' date code on the packaging," he explained further.

When it comes to reducing plastic waste, the company has committed to phasing out hard to recycle packaging items like water-soluble plastics, PVC contained in plastic wrap and polystyrene.

Environmental groups welcomed Tesco's plastics decision.

"As the UK's largest grocer, Tesco could be a game-changer on plastic packaging," Greenpeace UK oceans campaigner Elena Polisano told The Independent.

"By pledging to quickly eliminate some of the plastics that are difficult to recycle, it has raised the bar for action on problem plastics," she said.

However, green groups also said the supermarket could go further by reducing the total volume of plastics it produces, as competitors Lidi and Iceland have pledged to do.

Jason Tarry, the brand's chief produce officer, said at an industry event that the chain was "committed to reducing the total amount of packaging used across our business," The Independent reported.

He further said Tesco wanted to work with the UK government to develop a "closed loop" recycling strategy.

But Friends of the Earth plastics campaigner Julian Kirby said that recycling, while important, wasn't enough to combat plastic pollution.

"What's missing is the long-term vision—we need system change, and we need all stakeholders to step out of the comfort zone of thinking we can just recycle our way out of this," Kirby told The Independent.

Roof-to-Garden: How to Irrigate with Rainwater

By Brian Barth

The average American household uses about 320 gallons of water per day, a third for irrigation and other outdoor uses. Collecting the water flowing down your downspouts in rainstorms so you can use it to irrigate in dry periods is often touted as a simple way to cut back. But setting up a functional rainwater irrigation system—beyond the ubiquitous 55-gallon barrels under the downspout, which won't irrigate much more than a flower bed or two—is a fairly complicated DIY project.

Study: Children Have Better Nutrition When They Live Near Forests

Spending time in nature is known to boost mental and emotional health. Now, a new global study has found that children in 27 developing nations tend to have more diverse diets and better nutrition when they live near forests.

The paper, published Wednesday in Science Advances, provides evidence that forest conservation can be an important tool in promoting better nutrition in developing countries, rather than clear-cutting forests for more farmland.

Top Seed Companies Urge EPA to Limit Dicamba

Two of the nation's largest independent seed sellers, Beck's Hybrids and Stine Seed, are urging the U.S. Environmental Protection Agency (EPA) to place limits on the spraying of the drift-prone pesticide dicamba, Reuters reported.

This could potentially hurt Monsanto, which along with DowDupont and BASF SE, makes dicamba formulations to use on Monsanto's Xtend seeds that are genetically engineered to resist applications of the weedkiller. Beck's Hybrids and Stine Seed, as well as other companies, sell those seeds.

For tens of thousands of years, the Wangan and Jagalingou people have lived in the flat arid lands of central Queensland, Australia. But now they are fighting for their very existence. Earlier this month, they took their fight to the United Nations after years of Australia's failure to protect their fundamental human rights.
