StoPWa – Stormwater purification with construction and demolition waste

Statistics Finland states that Finland produces a staggering 1.6 million tons of construction and demolition waste a year. Brick and concrete waste and mineral wool insulation are difficult to recycle, but LUT is using them to create filtration compounds for stormwater treatment. The first step is to test the materials in soil laboratories in Lahti, Finland. Then, the tests will continue in dammed ponds in Lahti, Estonia, and Latvia.

Water treatment and the recycling of materials may create new business opportunities for local enterprises and help cities and municipalities to build environmentally friendly solutions for the treatment of stormwater.
The project are looking solution for using construction and demolition waste in stormwater filters

1. Reduction of nonpoint emissions of stormwaters and the Baltic Sea pollution burden
2. Improved recycling of construction and demolition waste
