Aquatic Moss Makes Contaminated Water Drinkable

Algae used to be fashionable, what with eco-friendly biomass algae shoes and green chandelier air purifiers. Something that looks quite similar (though is biologically different), moss, used to be functional and innovative, with equally eco-friendly moss-covered tires that absorb moisture and expel oxygen.

But now moss is just plain genius and essential, as scientists in Sweden discover an aquatic one that purifies water contaminated with arsenic, enough that it even becomes potable.

Researchers at Stockholm University say the aquatic moss, warnstofia fluitans, which flourishes in northern Sweden, can rapidly absorb arsenic, removing as much as 82 per cent of the toxins within one hour in some tests.

Due to mining operations in this part of Sweden, wetlands and water sources used for drinking and for growing crops are often contaminated with arsenic.

Arsenic is known to be a waste product from mining. Mine tailings are often toxic and difficult to separate from waste deposits, and toxin concentrations often end up in water sources. This makes mining a major environmental issue.

“We hope that the plant-based wetland system that we are developing will solve the arsenic problem in Sweden’s northern mining areas,” said Maria Greger, associate professor at the Department of Ecology, Environment and Plant Sciences at Stockholm University and leader of the research group.

The process of cleaning the contaminated water done by the aquatic moss is called phylofiltration. The researchers have also mentioned that sometimes this process takes no more than an hour, which is indeed very quick. If only more humans are inspired to be as quick to act in the name of the environment.

Activists Demand Recyclable Cups From Starbucks

If Starbucks isn’t your go-to for mocha frappuccinos, you’re probably living on another planet. Known for its wide range of flavors and misspelling names, the coffee chain is the largest in the world. With coffee moguls inventing edible coffee capsules, Starbucks still needs to step up its sustainability game. At GeekWire’s annual summit, protesters demanded recyclable cups from the food giant, creating a Cup Monster made with Starbucks products.

“If Starbucks CEO Kevin Johnson is serious about transforming his company into a tech leader, he must first solve his company’s biggest environmental liability: the 8,000 [plus] cups that go into landfills every minute of every day,” said Stand.earth spokesperson Ross Hammond.

What makes Starbucks cups mostly un-recyclable is its inner plastic lining. While the company claims to incorporate post-consumer fibers into its cups, recycling methods vary among different states.

“It’s important to note that what is recyclable varies significantly by municipality and sometimes even by store. We pay local private haulers across the country to collect and recycle hot cups along with our other recyclable products, compost and trash.”

Extremely recyclable? Sort of recyclable? Regardless of how recyclable Starbucks thinks its products are, there is always room to be more eco-conscious.

Scotland’s Wind Power Enough for 5 Million Homes

Attempts at finding alternative energy sources to fossil fuels might seem like everyday news—of course not futile, still of course productive and necessary, though less surprising. Every so often, some efforts make the world extra proud, extra green, and extra clean, like perhaps seeing the biofuel potential of kelp farms in the vastness of the Pacific Ocean and running an entire school in Denmark solely through solar power.

Today, one groundbreaking (or windbreaking?) story brings us a breath of fresh air. Scotland has achieved another wind power record by supplying energy equivalent to the usage of five million homes.

“Renewables have provided an incredible amount of power during the first three months of this year,” Dr. Sam Gardner, WWF Scotland’s acting director, said in a statement. “An increase of 44 percent on the record-breaking equivalent period in 2017 is clear evidence the investment made in this technology has paid off for the economy and the environment, putting Scotland at the forefront of the fight against climate change.”

In the first quarter of 2018, 5.3 million megawatt hours of energy were generated by Scotland’s wind turbines. March 1, considered so far as the best day in the country for wind power, produced 110,000 megawatt-hours of energy that could have provided for 173 percent of the nation’s entire electricity demand.

But WWF Scotland’s acting director is not only proud; he wants the potential of the country’s wind power production to serve as a call to action for the rest of the UK.

“If Scotland’s full renewables potential is to be unleashed to power our economy, heat our homes and charge our cars, then the UK government needs to stop excluding the cheapest forms of power, like onshore wind and solar, from the market,” he said.

With this record and all its implications for Scotland’s—and perhaps the UK’s—future, not only is Scotland taking our breath away, it is set to take the world by windstorm.

Apple Now Powered by Clean Energy

Corporate giants like McDonalds (along with other fast food chains) and Google (along with other tech companies) have been participating in the global venture towards turning green. Recently, another giant techie has joined the cause: Apple has announced that its operations are now completely powered by renewable energy. The company claims that all of its shops, offices, and data centers across 43 different countries are part of the program.

“We’re committed to leaving the world better than we found it. After years of hard work we’re proud to have reached this significant milestone,” said Tim Cook, Apple’s CEO.

“We’re going to keep pushing the boundaries of what is possible with the materials in our products, the way we recycle them, our facilities and our work with suppliers to establish new creative and forward looking sources of renewable energy because we know the future depends on it.”

In a similar vein, Apple has also built an Apple Park campus completely powered by solar energy, as well as other wind and solar projects in China to help counteract its manufacturing wastes. However, Apple products still come from suppliers that the Apple company does not have complete control over. In response to this, the giant has been active in encouraging its suppliers to improve their standards, inclusive of labor conditions and environmental work.

It has encouraged suppliers to follow its lead in using renewable energy, it said, and now 23 of them are committed to working on green power.

If corporate competition between biggies in various industries like food and tech keep happening on the green stage, then one victor would always emerge for sure: our environment. Let’s just hope the battle continues.

Mini Treatment Plant Putting Sewers To Good Use

As the planet is hastily running short of natural resources, communities are looking to waste as an asset. Anything from biochar to human excrement are now staples in energy production. To bring everything together, engineers have created the NEWgenerator, which processes materials found in sewage.

First, the waste is fed into a bioreactor, where anaerobic microorganisms break down the solids and produce biogas.

The methane produced is chemical-free and perfect for cooking and heating. To complete the cycle, USF engineers have also made the most of liquid and solid waste.

The water that passes through is… disinfected with chlorine, and while the end result is probably still not drinkable, it’s clean enough to use to flush the toilets in the block or irrigate crops.

The remainder of the waste can be used as fertilizer. So far, the system is testing waters in India and South Africa. Each device is usable for up to 100 people a day, with future versions projected to reach thousands. Considering that millions are without access to basic amenities, the NEWgenerator is a game-changer for marginalized communities.

Cemented Plastic Makes Concrete Stronger

The existence of eco-friendly, weather-resistant structures such as Thailand’s bamboo building are evidence that designers are saving the planet. To drive a point, MIT students are embedding irradiated water bottles into cement to make concrete more robust and sustainable.

The research revealed that exposing the plastic to gamma radiation actually made it stronger. The irradiated plastic was then ground into a powder and mixed with cement. The subsequent concrete was up to 20 percent stronger than concrete made without the irradiated plastic.

Engineers found the added plastic (only 1.5% of the concoction) made concrete significantly denser. If you’re skeptical about incorporating the mix into future room renovations, don’t worry — it isn’t radioactive. Furthermore, using plastic will potentially relieve a few dozen landfills.

“Concrete produces about 4.5 percent of the world’s carbon dioxide emissions,” says [MIT professor Michael] Short. “Take out 1.5 percent of that, and you’re already talking about 0.0675 percent of the world’s carbon dioxide emissions. That’s a huge amount of greenhouse gases in one fell swoop.”

Environmentalists might campaign for a plastic-free society — but it isn’t the easiest option. Perhaps, now, it’s all about redirecting your waste to where it will be most useful.

China Halts Factory Operations To Fight Pollution

China may be home to one of the world’s great wonders, but it’s also housing something far more dangerous — air pollution. It may be cracking down on carbon emissions with air-purifying bicycles and solar farms, but it seems efforts are lacking. A blessing in disguise, damaging factory activity has forced the country to shut down industrial regions to reevaluate environmental laws.

“After all, factories will be better, more sustainable, and more socially responsible after being inspected,” says [Archie Liu of MKT & Associates]. “It’s better for our supply chain. Then we can tell Walmart, Costco, and other retailers of ours that we’re qualified and that everything we make for Americans are environmentally friendly.”

With 40% of Chinese factories at a standstill, economic impact will be harsh — but totally worth it. Chinese tax bureaus will be taking over environmental groups, meaning greater consequences for law-breakers.

“It’s a huge event. It’s a serious event. I think many of us here believe it will become the new normal,” says Michael Crotty, president of MKT & Associates.

Criminal enforcement may sound overbearing, but in a deteriorating planet, may be just what we need.

Vegan Milk Delivery Service Is Tasty And Eco-Friendly

If going vegetarian is something up your alley, this nutty milk delivery service may be perfect for you. With Mylk Man, ditching dairy has never been simpler.

Mylk Man offers your classic plant-based flavours, like almond, in addition to funkier bottles, like pistachio and sweet chai and turmeric and cashew.

As well as these fancier varieties giving them an edge on supermarket-stocked brands, there’s also the 12 per cent minimum volume of nuts in every bottle – significantly higher than most mass-produced blends.

As a vegan lifestyle is clearly all the rage, Mylk Man should be nothing short of a hit. 500 ml bottles start at £1.75. Glass material makes them easy to recycle or return for future deliveries. Unfortunately for any neighboring European countries, Mylk Man is London-based (but there are talks of expansion).

“Sustainability is fundamental to what we do,” says [business owner] Jamie. “As well as being plastic-free and using glass bottles, we give 10 per cent of our profits to Greenpeace. And we’re stocked in massive tanks at the Bulk Market zero waste shop, in Dalston.”

For a taste, I’d say an impromptu weekend in London wouldn’t be out of the question.

Deep Water Wind Farm Is Powering The Scottish Grid

Following the success of solar power, developers have been harvesting clean energy from other sources. Now that we can accumulate electricity through passing vehicles and even cow excrement, nothing else seems far-fetched. Wind power may be nothing new, but these floating offshore turbines are the first of their kind.

The 30MW installation… will demonstrate that offshore wind energy can be harvested in deep waters… where installing giant turbines was once impractical or impossible. At peak capacity, the wind farm will produce enough electricity to power 20,000 Scottish homes.

The irony behind the nautical wind farm is its contractor — Statoil. The company is a corporate giant notorious for oil drilling. It’s somewhat of a paradox, but I’m a fan. Statoil claims that the wind farm’s offshore location is also beneficial.

The farther out you can place offshore turbines, the steadier and faster the wind is. It also comes with the added benefit of avoiding any community arguments over clean ocean views… [also] unimaginably large rotor components can be delivered by sea rather than by land, where roads have weight limits.

In the end, Statoil is living proof that you can easily give back what you take from nature. While we’d rather leave Mother Nature alone entirely, compensation is better than nothing.

Netherlands Home To 3D-Printed Cycling Bridge

Inner Mongolia’s solar powered Dragonfly bridge may be the walkway of the future — but not soon enough. Filling the gaps is Eindhoven University of Technology, which 3D-printed the world’s first cycling bridge.

“One of the advantages of printing a bridge is that much less concrete is needed than in the conventional technique in which a mould is filled,” it said on [the university] website. “A printer deposits the concrete only where it is needed.”

The bridge is nothing grand in scale, but can reportedly withstand the weight of 40 trucks. While I don’t suppose you can cram that many vehicles onto a 26-foot bridge, the point is clear. The university’s partner company BAM Infra is hopeful that the bridge will inspire more efficient technology.

[BAM is] “searching for a newer, smarter approach to addressing infrastructure issues and making a significant contribution to improving the mobility and sustainability of our society.”

In the 3D-printing world, the Netherlands remains on top of cutting-edge resources.
