Welcome to HTCycle!

It is a great pleasure to welcome you to our website!
We hope you will find here the necessary information about our services, technology and other interesting facts regarding the hydrothermal carbonization process.

HTCycle offers a holistic solution to close nutrients and material life cycles. Our technology represents a different perspective of how we could use the sewage sludge to generate valuable limited nutrients like phosphorus, sulphur, carbon etc.

Combining our engineering skills and driven by the idea that we need to keep our planet green and in the same time to assure an ecosystem balance of fundamental nutrients, we have developed the only clean, sustainable and profitable way for sewage sludge treatment.

Hydrothermal carbonization plant
a solution for residues and biomass
Hydrothermal carbonization is a chemical process for the conversion of organic compounds to structured carbons. The process, which technically imitates the brown coal formation taking place in nature within 50,000 to 50 million years within a few hours, was investigated by Friedrich Bergius and first described in 1913.
additional support for our clients
HTCycle GmbH experts provide additional services like: engineering, consultation and planning for the clients that intend use the hydrothermal carbonization as a waste disposal solution which generates products like coal and phosphor.
