CURRENT FOCUS

The management and disposal of high-water content biowaste such as sewage sludge is an increasingly difficult problem. Anaerobic digestion provides only a very partial solution.

Concerns about the presence of highly persistent chemicals, pharmaceuticals and micro-plastics in biosolids has meant that spreading on land is now subject to increasing restrictions.

We are therefore very pleased to announce that we are working on a major industrial scale initiative to demonstrate that Hydrothermal Carbonisation (HTC) offers the most cost-effective solution to the problem of high-water content sludges.

HYDROTHERMAL CARBONISATON (WET PYROLYSIS)


Using Hydrothermal Carbonisation, wet biomass feedstocks such as sewage sludge at 3-5% dry solids is dewatered to 15% dry matter with no further drying required.
 
In the HTC reactor the dewatered biomass is carbonized into hydrochar (biocoal) within 4 hours at a temperature of about 180-200°C and a pressure of 20 to 25 bar. The hydrochar / biocoal can then be easily dewatered to 75% dry matter.
 
Hydrochar has an energy content similar to anthracite and can be used as a substitute for fossil fuels in many industrial applications.
