DRACO is a HydroThermal Carbonization (HTC) solution for sludge volume reduction. It reduces sludge volume by 80% and up to 90% with a dryer preventing sticky phase reducing overall energy costs.
When combined with an anaerobic digestor, DRACO system increases biogas production by over 30%.
DRACO can also be integrated with heat-generating plants such as incinerators, coal-fired power plants, and cement plants. By utilizing waste steam from these facilities as a heat source, it operates without the need for external energy input.
In addition, DRACO retrofits existing sludge dryer process, eliminating sticky phase issues, stabilizing dryer operation, and reducing 70% of energy costs.
Don’t be surprised — DRACO can operate as either THP or HTC, depending on your objectives and configuration. It’s designed to adapt, not compromise.

DRACO HTC undergoes the same initial hydrolysis phase as DRACO THP, followed by dehydration and decarboxylation to complete the reaction process

DRACO is a patented HTC system using a batch process with stepwise heating, pressurizing, cooling, and depressurizing of biosolids. Components include: Hopper, Pre-heating Tank, Reactors, Decompression Tank, Heat Exchanger, and a Filter Press line.
DRACO can process sludge regardless of water content through effective mixing and high heat transfer efficiency, using a patented multi-point steam injection technology.
- Improved contact between sludge & steam through the use of an agitator
- Enhanced heat transfer efficiency through patented multi-point steam injection technology
- Uniform heat distribution enables complete reaction of organic waste
- Heat transfer efficiency validated through 3D flow analysis
