GHT technology solves waste disposal problems.
Green Hydrogen Technology’s production process relies on climate-friendly hydrogen production from sewage sludge, plastic waste and wood waste.

Sewage sludge
In Germany alone, nearly 1.9 million tons of sewage sludge are produced annually (source: Eurostat Data, 2020). Sewage sludge contains valuable phosphate. From 2029, EU law requires that phosphate be removed from sewage sludge before it is disposed of in landfills. So far, there is no economical process for this. Extraction is complex and expensive.
GHT technology uses sewage sludge as a fuel for gas generation. Separation of the phosphate is part of the process and requires no additional effort. This is because the high temperature in the gas burner extracts inorganically bound substances in the form of phosphate slag. Thus, hydrogen production produces phosphate in crystallized form as a by-product.
Wood waste
Despite well-developed recycling systems, a large proportion of wood waste cannot be recycled. In Germany, this amounts to 11 million tons per year (source: Technology for Wood and Natural Fiber-Based Materials. Research project of the Fraunhofer Institute. Data: Federal Statistical Office, 2020). In the GHT process, valuable synthesis gas is produced from wood waste..


Plastic waste
There is no sensible use for plastic waste that cannot be recycled. In Germany, this amounts to 3.8 million tons per year (source: Plastic Atlas, Bund für Umwelt und Naturschutz Deutschland, 2019). These residual materials are incinerated, landfilled or even disposed of in the sea. In the GHT process, valuable synthesis gas is created from plastic waste and thus provides an economic and ecological benefit.
