Environmentally-friendly

Concrete is a mix of cement, an aggregate such as gravel, and water. For added strength, steel fibers are often added. Now, scientists are claiming that a new type of fiber-reinforced concrete could soon serve as a lighter and greener alternative.

A new juice kiosk recycles its own orange peels into the cups used by the customers.

Microfluidic chips are typically made out of plastic, but scientists are now taking a more eco-friendly approach, using wood.

​Living in the soil, roundworms can infect plants via their roots, which is why many plants have evolved to produce an immune response when the worms are detected. Now, scientists have harnessed that response to create an eco-friendly form of crop protection.

​An estimated 429,000 people die from malaria annually. And while it's tempting to spray heavily for the mosquitoes that spread the disease, conventional insecticides are also toxic to humans and other animals. Now, however, a neurotoxin has been discovered that only kills the offending mosquitoes.

​It was a year ago that we first heard about Transcend Air Corporation's Vy 400, a vertical take-off and landing (VTOL) aircraft that will ferry passengers in and out of cities. Now, the Boston-based company has announced plans for floating environmentally-friendly landing pads for the aircraft.

​Do meal kits have a larger carbon footprint than regular grocery store shopping? A team of environmental researchers set out to crunch the numbers ​discovering that despite the extra plastic waste meal kits may produce less environmental emissions than conventional grocery shopping.

​Given that they're applied to items such as furniture and home insulation, it would really be best if flame-retardant coatings didn't emit toxic fumes. That's why scientists from Texas A and M University have developed a non-toxic alternative, made from natural renewable materials.

The Ocean Cleanup barge is currently on its way to tackle the Great Pacific Garbage Patch, but it never hurts to find ways to reduce plastic before it gets into the sea. In that vein, Danish beermaker Carlsberg has announced the Snap Pack, a simple alternative to plastic six-pack rings.

​Some of the earliest houses in Northern Europe were made out of slabs of peat, as it was a cheap and abundant building material. Now, Estonian scientists are revisiting the idea of peat houses, only this time they're looking at 3D-printing the things.

​Although chlorine-free public natural swimming pools have become popular in Europe, so far there has only been one in North America – the Webber Park pool in Minneapolis. That's about to change, however, when the Borden Natural Swimming Pool opens in Edmonton, Alberta later this week.

To make concrete more environmentally friendly, the industry has been adding by-products from coal-fired power plants, but doing so had its own problems. Now, Rice researchers have developed a new composite binder that requires no cement, and reduce waste from power plants at the same time.
