Material Utilisation, Legal Framework Conditions, Sustainable Recycling

Sewage sludge

Sewage sludge is produced during the treatment of wastewater at sewage treatment plants and contains a high proportion of nutrients - especially phosphorus and nitrogen. However, sewage sludge is also a pollutant sink in the wastewater treatment process. Heavy metals, organic pollutants (as pharmaceuticals and hormonally active compounds) as well as microplastics are bound in sewage sludge and are thus removed from the treated wastewater and the environment. Through agricultural utilisation, these substances once again enter our ecosystem. The pollution of water bodies, sediments and soils with these substances and the effects on humans and the environment are largely unknown.

The material utilisation of sewage sludge has therefore been controversially discussed for a long time. Due to increasing quality requirements, following legal framework conditions, the use of sewage sludge as fertilizer in agriculture has stagnated in recent years. Sewage sludge disposal needs to be rethought.

sludge2energy GmbH is on hand to advise you on developing sustainable and innovative utilisation strategies for your sewage sludge.

Sustainable and innovative utilisation strategies for your sewage sludge

Sewage sludge has many facets

Origination, disposal and utilisation of sewage sludge is a multi-layered and complex subject area that involves various factors and starting points.

For the sustainable, environmentally sound and future-proof handling of sewage sludge as a resource, it is worthwhile to take a closer look at the topics listed below. This holistic approach has contributed significantly to the development of the "sludge2energy process" and thus to disposal safety and environmental protection.
