Superefficient sludge handling

Presenting a revolutionary new way to convert wet sludge into biofuel

 

Wastewater sludge, industrial sludge, wet biomass – it's a problem that has to be dealt with. We have developed a robust industrial-strength process to convert sludge into a valuable asset called hydrochar.

We use a proven method – hydrothermal carbonization – but with several innovations to make it into what is probably the most efficient sludge disposal method for the 21st century.

Features

Our goal is to turn hydrothermal carbonization (HTC) into a modern and cost-effective solution for almost any wet biomass sludge problem. Through innovation and modern industrial design, we believe our Zero Energy HTC solution will become the new environmental benchmark for nearly all sludge disposal problems. 

 
 

Impressive Dewatering

Go from 70-90 % water content down to 30 %, without using any external heat. It's simply the most efficient way to dry large quantities of wet biomass!

Zero HEAT HTC

Our patented invention that changes conventional, energy-intensive HTC into a process with no need for external heat energy.

Hygienic

High pressure and temperature levels eliminates bacteria, fungi, and viruses. The result is an odor-less and sterilized hydrochar.

 

High capacity

Processes up to 10 tonnes of sludge per hour on a space equivalent to 5 parking spaces.

Making fuel

Zero Energy HTC turns wet sludge into a dry economic biofuel with excellent energy properties. It's ideal for use in a biofuel heat and power plant.

Continuous

The Zero Energy HTC process is continuous, and uses our own patented FracFlow reactor design. Easy to use and better performance than traditional HTC.

Hydrochar

A VALUABLE BIOFUEL

This is what hydrochar looks like. Our HTC process efficiently turns wet biomass into a dry hydrochar product using a minimum of external energy. The process eliminates bacteria, fungi, and viruses, and immediately stops greenhouse gas emissions caused by organic decomposition.

Hydrochar is perfectly suited as a biofuel in a modern heat and power plant.

 

Characteristics

Dry | moisture level around 30 %.

Valuable | high-energy content equal to standard wood-based biofuels.

Sterile | hygienic, safe and easy to transport.
