Superefficient sludge disposal

Presenting a revolutionary new way to convert wet sludge into biofuel

 

Wastewater sludge, industrial sludge, wet biomasses – it's a problem that has to be dealt with. We are busy developing a robust industrial-strength process to convert all that sludge into a valuable asset called biocoal.

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

Features

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

 
 

Impressive Dewatering

Go from 80 percent water content to 30, practically without using any external energy. It's simply the most efficient way to dry large quantities of wet biomass on the planet!

Zero Energy HTC

Our own patented invention to reduce the traditional heavy-energy HTC to a process with basically no need for external energy.

Hygienic

The high preassure and temperature eliminates bacteria, viruses and most complex pharmaceutical residues. The result is an odor-less clean biocoal.

 

High capacity

Small footprint. High capacity.

Process 60 tons of sludge per day on a space equivalent to 5 parking spaces.

Making fuel

HTC turns wet sludge into a dry valuable biofuel with excellent energy properties. It's ideal for use in a biofuel power plant.

Continuous

Our Zero Energy HTC process is a non-batch process, and uses our own FracFlow reactor design. The result is ease-of-use and better performance than traditional HTC.

Biocoal

The new sludge

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

The biocoal is perfectly suited as a biofuel in a modern power plant.

 

Characteristics

Dry | moisture level around 30 percent.

Valuable | energy content equal to regular wood chips.

No smell, inert, easy to transport.

But for now, we'd like to keep things under wraps a little bit longer. Our team has extensive experience with industrial process design, and we know the time required to design a product for heavy industrial use. And we want to make sure that we've tested (and retested) everything so that we can offer the best product possible.

However, if you're interested in our unique HTC solution for sludge disposal, or have a pressing sludge problem that has to be solved, please don't hesitate to contact us! We have plenty of more information to share after an initial contact.
