Eco-friendly flame-retardant coating made from plants and clay

Ben Coxworth February 13, 2019

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.

Flame-retardant coatings exist for a reason, but they may not need to be made from toxic ...

Carlsberg crafts new six-pack holders to cut plastic waste

Michael Irving September 10, 2018

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.

Danish beermaker Carlsberg's six-packs will now be glued together as the Snap Pack

Inexpensive houses could be 3D-printed from peat

Ben Coxworth July 10, 2018

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.

Canada's first public natural swimming pool set to open in Edmonton

Ben Coxworth July 9, 2018

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.

Using the Borden Natural Swimming Pool is said to be like swimming in "a very, very, ...

Coal plant waste helps build environmentally-friendly, cementless concrete

Michael Irving June 18, 2018

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.

Carrots n' beets used to strengthen concrete

Ben Coxworth June 15, 2018

It was back in April that we heard about how scientists had made concrete stronger and more eco-friendly by adding graphene to it. Now, researchers at Lancaster University are reporting that they've achieved even better results using cheaper "nano platelets" derived from root vegetable fibers.

The enhanced concrete contains nano-platelets derived from carrot and beet root fibers

A tobacco-derived insect repellent – for crops

Ben Coxworth June 7, 2018

Although it's associated with nasty cigarettes, the tobacco plant is also a potential source of vaccines, biofuel and antibiotics. Now, a chemical from the plant is also being used as a bug repellent for crops, which could replace eco-unfriendly insecticides.

Blackcurrants could be a green source of hair dye

Ben Coxworth May 29, 2018

Traditional synthetic hair dyes can be quite toxic, not only to our bodies, but also to the environment. As a result, scientists are developing non-toxic dyes based on substances such as graphene. Now, it appears that waste blackcurrant skins can also do the job.

Blackcurrant skins contain pigments called anthocyanins

Environmentally-friendly fabric created from microbial cellulose

Paul Ridden May 23, 2018

Organic cotton, hemp, bamboo and even recycled plastics are being transformed into clothing for eco-aware fashionistas. Australia's Nanollose is going an even greener route with a system that makes use of biomass waste from the coconut industry to create a plant-free fiber.
