One person’s by-products are another person’s raw materials.

WaVa is a digital marketplace for the sale and buy of industrial by-products (waste)

For sellers

Disposal of industrial waste is a cost for businesses and the environment.

Some of the waste you produce can be a raw material for another industry. By implementing a reuse chain, we enable you to have a new revenue stream.

For buyers

Purchase by-products to secure your supply chain. This will allow you to access a new source at a more competitive price than buying raw materials through standard channels.

By purchasing industrial by-products, we enable you to secure a complementary supply chain and reduce the risk of disruptions.
