Environmentally-friendly

MIT engineers have found a new use for a common plastic, spinning polyethylene into fabric that can passively cool the wearer by allowing heat through and moisture to evaporate. The discovery could see waste plastic bags being turned into sportswear.

Unfortunately concrete production is a major source of carbon dioxide in the atmosphere. Now engineers at Purdue University have developed a new cement recipe that can absorb CO2 twice as fast as usual, hopefully turning it into a useful carbon sink.

While pest insects can have a devastating effect on crops, pesticides can likewise cause a great deal of damage to the environment. That's where CropCoat comes in, as it's designed not to kill harmful insects, but to "hide" plants from them instead.

Just like us, crop plants are subject to bacterial infections. And while antibiotics are often used to kill those microbes, compounds extracted from fly larva fat may prove to be a more eco-friendly alternative.

While 3D printing technology does allow for the quicker and cheaper construction of buildings, such structures are typically made of concrete, which isn't very eco-friendly. Soon, though, it may be possible to print buildings out of local soil.

Although superglues can be quite useful, they're typically made from harsh chemicals, plus it's very difficult to "unstick" them once they've set. Now, however, scientists have created a plant-based superglue that can easily be removed when needed.

Not only are diamondback moths quite harmful to brassica-genus crops such as cabbage, broccoli and canola, but they're also very resistant to insecticides. Help may be on the way, though, in the form of a genetically-engineered version of the moth.

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.
