Sewage Sludge Utilization: technology with a future

Our Solutions

Our patented process, which has been tried and tested for over 15 years, uses dried sewage sludge to recover electricity and heat. The process is decentralized, for example directly on the site of the wastewater treatment plant. This saves transport costs, protects the environment and is both sustainable and economical.

All solutions are based on the principle of gasification. The energy in the solid sludge is converted under high temperatures and a reducing atmosphere into the gas phase. This synthesis gas can then be converted into usable energy in a much more variable and efficient way, especially when smaller treatment plants are considered.  The differences between the plant types offered occur primarily in the type of synthesis gas utilization, but also in the synthesis gas production, which is adapted to the downstream application.

All our solutions produce the same solid product: a versatile, phosphorus-rich, low-carbon and decontaminated ash in the form of mineral granulate, which can be used as a fertilizer either directly or indirectly, and which can be used as an aggregate for the production of asphalt or as a backfill material in road and civil engineering.

The annual capacity of the plants on offer starts with the smallest Heat Module variants with 1,000 t/a dried solids and reaches a maximum of 15,000 t/a dried solids per line.

The choice of the right SynGas plant is based primarily on the site-specific energy requirement and the annual sludge volume. With the various solutions, we can cover the full range from a turnkey CHP Module for highly efficient power generation, a Heat Module for pure heat utilization to retrofitting an existing incineration plant with a SynGas Auxiliary Firing Module for the co-incineration of sewage sludge with simultaneous separation of the ashes (requirement of the German Sludge Ordinance (AbfKlärV).  We will be happy to advise you personally and draw up an individual offer for you.

Your advantages with solutions from KOPF SynGas at a glance:

  • Economically viable solutions ranging from decentralized, thermal sewage sludge utilization plants directly at the wastewater treatment plant to semi-centralized plants for operation in regional networks.
  • Variable energy utilization possibilities due to the flexible synthesis gas fuel for increased profitability
  • Production of a clean and nutritious ash for fertilizer production, phosphorus recovery or direct use as fertilizer
  • Our ashes are nearly carbon-free (no pyrolysis coke, pyrolysate or similar)
  • The possibility of an energetically self-sufficient wastewater treatment plant, especially in combination with sludge digestion/biogas combustion in a CHP motor.
  • Co-combustion of sludge-derived syngas as an auxiliary fuel in accordance with the new sewage sludge ordinance (AbfKlärV)
  • Long-term, predictable sewage sludge disposal costs
  • 17 years of experience in the field of sewage sludge gasification at KOPF SynGas!
