A product is a new tree in the world

Trees are essential elements of the planet, benefiting both people and the environment. They assist us by purifying water and air, and creating better social conditions. They support the environment by providing habitats for various life forms, mitigating climate change, and improving soil quality.

At String Project, we believe it is our duty to take care of the Earth and take concrete actions to restore the balance and vitality of our planet’s forests. Joining the Tree-Nation project is just the beginning of our commitment to contribute towards this important goal.

For this reason, we have decided to plant one tree for every product sold.

Plastic Recycling and Recovery

Plastic pollution is one of the most serious environmental threats of our time. Every year, between 8 and 12 million tonnes of plastic end up in the oceans, where it accumulates to form huge floating islands.

For this reason, we decided to partner with Plastiks.io, a Greentech company that improves plastic recovery and recycling rates by connecting companies with recovery projects around the world.
