Water Producing Tree Guard: From Demonstrator to Large Scale Production

Project description

Tree guard technology provides its own water supply

Sponsh Water Systems SL is developing a self-watering tree guard based on a hygroscopic temperature-sensitive smart textile. The material can repeatedly absorb water from the air and then release it, using natural temperature cycles of day and night. The EU-funded TreeSponsh project will develop the chemical products and test the technology so that it can be scaled up and used in reforestation projects, commercial forestry and arid farming. The researchers will use their knowledge of substrates and hydrogels to develop the Sponsh manufacturing process and replicate the production line across the world. The goal is to provide water from air for 1 billion young trees by 2040 while also providing affordable water for the local communities.
