Soluterials is a German startup that developed a new type of aluminum by recycling existing streams, while also improving its strength and durability. SoluteriAL, as the material is known, is durable, has good electricity conduction abilities, tolerates heat better than regular aluminum, while also resisting deformations better. And it can be recycled entirely, as per Tech.eu, making it the go-to-choice for companies that want to implement it in new products.

Maybe recycling fiberglass-made boats isn't on our priority list when it comes to sustainability, but for this Italian startup, it is a great business opportunity. Thus, Nlcomp (Northern Light Composites) uses a proprietary technology to reprocess end-of-life fiberglass materials from boats.

The company recently launched the world's first recyclable production boat, called ecoRacer 30, featuring a thermoplastic matrix that allows the boat to be recycled easier than traditional vessels.

Nlcomp doesn't focus only on making boats, as it currently collaborates with wind turbine company Windcity to develop recyclable wind blades.

PrintyMed is a Latvian startup that focuses on implementing spider silk produced by bacteria in medical applications for things like tissue engineering. These materials are pure enough to be used for things like building artificial nerves, bones and heart fibers, while also having the potential to be used for things like skin reconstruction.

These are just some of the startups that make use of nature's abilities or existing resources to create new products that can enable us to live more sustainable lives.
