Values and pain-reliefs for our customers

• Reduced sludge handling costs

• Reduced sludge volumes, less handling & transportation

• Significant reduction of CO2-footprint

• Less disturbances from odour and transports related to sludge handling

• HTC-product can be used as a biofuel

• HTC-product is free from biological and pharmaceutical activity
