Reinventing the liquid waste disposal process

Project description

A pioneering sewage sludge treatment solution

The adoption of strict rules aiming to protect the environment has rendered the treatment of sewage sludge a problem for small and medium-sized wastewater treatment plants (WWTPs). As a result, WWTPs are urgently seeking environmentally friendly and cost-efficient solutions for sewage sludge treatment. The Swiss company TreaTech has developed a pioneering technology that can transform different types of liquid waste into useful products such as biogas, clean water and mineral salts. The solution offers lower CAPEX and OPEX for the plants and leads to 94 % lower CO2 emissions than existing technologies. Moreover, it requires less space and only a few minutes to generate up to 80 % more renewable gas. The EU-funded WAS2VAL project will prepare the introduction of the new solution into the market.
