by PH2 plant engineering

PH2 Technology GmbH is specialized in highly innovative plants for sewage sludge drying, phosphorus recovery and the production of green energy from sewage sludge and biogenic residues.

The sewage sludge drying of PH2 is carried out in the most efficient way by using low temeperature. This reduces disposal costs by 30 to 70 % compared to current methods.

The PH2 recycling process of phosphorus is characterized by very high recovery rates and the avoidance of MAP formation which very problematic for wastewater treatment plants.

Energy - produced from waste.
Efficient, eco friendly, self-sufficient.

A sustainable process is used to produce green hyrogen, green methanol or green methane from sewage sludge or biogenic waste.

The processes patented by PH2 Technology GmbH improve the processes currently available on the market in the field of energy efficiency and cost reduction many times over.

Our partner company Proemtec Behnke Präzisionsmeßtechnik GmbH has been developing and refining the CO2-neutral processes since 2016. PH2 Technology GmbH will be founded in 2023 for the renewable energy sector.

In this way, customers of PH2 Technology GmbH make an important contribution to decarbonization and climate protection with their systems.
