Compact system for wastewater sludge utilisation

Spreading sewage sludge on arable land pollutes the earth with heavy metals, microplastics and antibiotics. It also produces high methane emissions and odour or sanitation issues. Large scale incineration often requires long haul transportation and is subject to high gate fees.

Empyrio offers a low-cost solution for small and medium cities of 20,000 to 200,000 inhabitants: compact onsite sewage sludge utilisation systems for small and medium-size wastewater treatment plants. Ash from Empyrio sludge utilisation processes may be used for the recovery of phosphorus.
