Carbonisation for Upcycling - Waste and Recycling

Biomass contains much more than just the energy of the future. Selected biogenic residues (SRC wood, silage waste, extract residues, paper fibre sludge…) can be refined into new, valuable products such as biochar, charcoal feed or activated carbon by carbonisation (charring). But even if the material can no longer be refined, you benefit from the carbonisation in the PYREG process.


In the following you will find examples. The list is not exhaustive. Your recycling material is not listed? Talk to us. On behalf of our customers and numerous research projects, we have already tested a wide variety of feed materials. We also generally offer our customers a material test with subsequent analysis of the material, so you can play it safe.

  • Fermentation residues
  • Manure, dry manure
  • Cereals (waste)
  • Finishing, husking
  • Silage (waste)
  • Hay, straw
  • Wood chips
  • Wood pellets
  • SRC wood
  • NaWaRo
  • Branch and shrub pruning
  • Green waste
  • Landscape conservation material
  • Compost sieve
  • Organic waste bin
  • Grape marc
  • Draff
  • Extract residues


  • Nutshells
  • Fruit stones
  • Sawn timber


  • Liquid manure
  • Sewage sludge

  • The input material is completely recycled to carbonates and excess regenerative heat.
  • There are no other by-products to dispose of.
  • Reduction of the input quantity by up to 80% (with a P500 plant of 1,400 t of original substance only approx. 300 t of carbonate remain).
  • The gentle thermal treatment leads to the destruction of pathogenic pathogens and organic pollutants.
  • Carbonisation is active climate protection: A large part of the carbon contained in the input is stably bound in the carbonaceous material and thus removed from the cycle.
  • The generated usable waste heat of up to 150 kWth (P500 system) or 450 kWth (P1.500 system) can be used for heating and drying purposes or for electricity generation.
