It all started with individuals making changes in their lives to avoid single-use plastic, then moved to small shops offering plastic-free shopping. Nothing wrong with that says the UK version of Wired, but what is really needed more is for large supermarket chains to get on board.

Nicole Kobie writes at Wired, “Plastic-free, zero-waste shops — which include Bulk Market and Harmless in London, and Refill Store in Truro, Cornwall — are a utopia for people looking to ditching single-use plastics, and have even inspired (or shamed) some larger retailers into following their lead and cutting down on packaging. …

“Using reusable containers has benefits; it avoids the environmental costs of manufacturing and disposing of single-use plastic packaging and reduces littering. [But] says Simon Aumônier, principal partner at Environmental Resources Management (ERM). ‘The issue is it’s not always as simple as that.’ … The overall environmental impact can be small compared to other choices, such as reducing meat consumption.

“Here’s how to make the most of shopping plastic-free, and why it matters what you buy, where you buy it, and how you carry it home.

“Plastic-free stores require shoppers to bring their own reusable containers (or buy them in-store) in which to ferry home their pasta, nuts and other dry goods.

Shunning single-use plastic means it doesn’t end up in landfill or choking a turtle. ‘Every time you use your own container, you’re cutting down the amount of plastic you would have been responsible for,’ says Clare Oxborrow, a campaigner at Friends of the Earth.

“However, as with the plastic bag versus reusable tote debate, it matters what you use in place of the single-use plastic packaging, and how often you use it. …

” ‘Replacing a piece of single-use plastic packaging with a Tupperware container means you’ve got maybe ten times the material — therefore you need to reuse it maybe ten or 20 or 100 times before it’s a better solution in material consumption terms,’ says Aumônier. …

” ‘Glass and metal are more robust for the long term and can often then be recycled at the end of their life much more easily than plastic can,’ says Oxborrow. ‘Because of the way the system is set up, only about nine per cent of plastic ever made has been recycled. [We] have to stop using so much plastic in the first place.’ …

“There is a reason single-use plastic is used for packaging: it works. One study shows that cucumbers wrapped in plastic stay fresh for up to two weeks longer than ‘naked’ ones. And a cucumber that gets chucked in the compost bin is a waste of water and transport (and related emissions), regardless of how it was packaged. … Pasta, nuts and the like have a longer shelf-life, so are less likely to be wasted once brought home, and less likely to get damaged in store. …

“Biodegradable plastics are seen as one solution, but [Helen Bird, resource management specialist at WRAP] warns they aren’t necessarily as green as they may seem, as they also require fossil fuels to produce and often aren’t actually compostable. ‘To a large degree, the infrastructure that we have in place at the moment in the UK is not set up to make those plastics actually compost,’ she says – meaning they end up in landfill or are incinerated.

“Budgens in Thornton swapped paper for plastic bags on bread, Bird notes, but that led to problems as shoppers couldn’t see what they were buying. Sales slumped. … The supermarket has now found the right balance, with one store offering 1,700 plastic-free products, showing alternatives can be found.

“Plastic-free stores are usually locally-run businesses, and stock locally-produced food. While that has social benefits, whether local production has environmental benefits depends on the food in question. … How you get to the store also matters. If you’re walking or taking the bus to a local zero-waste store, you’re doing it right. …

“Local, simpler shopping doesn’t require a zero-waste store, of course — old-fashioned local butchers and greengrocers also fit the bill, though many high streets now lack them. ‘A lot of them shut down because they can’t compete with the supermarkets,’ notes Oxborrow. And that means we get into cars and drive to buy plastic-wrapped cucumbers instead. …

“Sarah Laidler, an analyst at the Carbon Trust, notes it’s best to buy locally grown and in-season, and to eat fruits and vegetables quickly so packaging isn’t required. ‘But vegetables don’t account for the bulk of carbon emissions in most people’s diets.’

“And then there’s processing. Those jars of dry beans and other ingredients are light to transport and easy to store, but require home cooking. …

Rather than try to calculate the merits of canned chickpeas versus dry, it makes more sense to make changes we know work, says Aumônier, such as only boiling the amount of water needed for a cup of tea and putting a lid on a saucepan to keep heat escaping.

” ‘These things can dramatically multiply the impact of the food and they’re easily overlooked.’ Laidler adds: ‘A key step Pepsi took to reduce the emissions of its Quaker Porridge Oats was to cook them more in the factory, so it was then cooked less at home.’ …

“And that’s the core issue at the heart of plastic-free stores: there are bigger changes we could make more easily. That doesn’t negate the positive impact of zero-waste shops, notes Bird, as they act as gateways to encouraging people to think when they shop — and they help shame larger supermarkets into action.

“Supermarkets are starting to clean up their act, albeit slowly. [It’s] better for everyone if the supermarkets themselves also change their practices, so the least amount of single-use plastic is used even for those who aren’t within striking distance of progressive shops in Dalston or Cornwall. ‘Ultimately we need to see the supermarkets embracing reuse culture,’ Bird says.” More at Wired, here.

And for coffee drinkers who compost, consider Dean’s Beans. However, you do need a really robust compost pile to break the bags down, we’ve found.

Part of the movement to bring your own containers to takeout restaurants or as a “doggy bag” after dining out is a shop is in Providence, RI.

Once again, Sweden is ahead of the curve, as it tests two versions of an electric road. The idea is to move away from fossil fuels and creative a more sustainable energy future.

Green Car Congress is a website that covered the story in June.

“Sweden inaugurated a test stretch of electric road on the E16 in Sandviken, thus becoming one of the first countries to conduct tests with electric power for heavy transports on public roads.

“The test stretch on the E16 is two kilometers long. The technology is similar to light rail, with contact lines 5.4 meters over the roadway. The truck has a pantograph on the roof that feeds 750 VDC to the truck’s hybrid electric system. The current conductor can connect automatically at speeds up to 90 km/h (56 mph). The test stretch is equipped with posts 60 meters apart that hold up the electric lines over one of the lanes.

“At a rest area, there is a transformer for low-voltage direct current of the same type as in the light rail network. Other traffic on the road will not be affected. …

“An electrified road is one in which the electricity supply for vehicle propulsion is continuously supplied in order to keep the vehicle moving and to avoid recharging requirements. …

“The technologies for electric roads have developed rapidly over the last few years, and are now mature enough that some of them can be tested. Last year, the Swedish Transport Administration, in consultation with Vinnova [Sweden’s innovation agency for sustainable growth] and the Swedish Energy Agency, decided to give support to two test facilities. The two systems differ as to how electric power is transferred to the heavy vehicles.

  • The test on the E16 in Sandviken is being carried out by Region Gävleborg, and involves a pantograph on the roof of the truck cab feeding the current down to a hybrid electric motor in the truck.
  • Outside Arlanda, the eRoadArlanda consortium company will test a technology that involves an electric rail in the roadway charging the vehicle during its trip. …

“The tests will continue up through 2018. They will provide knowledge of how electric roads work in practice, and whether the technology can be used in the future. The experiment is based on the Government’s goal of energy efficiency and a fossil fuel-free vehicle fleet by 2030, and will contribute to strengthening Sweden’s competitiveness.”
