Acceptance criteria

For reasons of ecology and immission control law regulations, we cannot accept all kinds of biomass. We only accept waste wood of classes AI to AIII and green waste such as branches, hedges, stools etc.

The waste wood classes are explained here.

Moreover, any biomass delivered must not be contaminated with foreign matter.

Otherwise, we will not be able to accept your delivery.

The following biomass contaminants are not admissible:

  • Glass (e.g. mirrors of cabinet doors)
  • Textile fibres (e.g. residual seat upholstery)
  • Inert materials (e.g. residues of mortar at formwork panels)
  • Plastics (e.g. decorative strips)
  • Stones
  • Soil

Compost, lawn clippings and class AIV waste wood are as a rule not accepted!

Metal contaminants are removed from the biomass by means of various separation methods, so you do not need to dismount metal parts.

Prior to unloading, declare your biomass delivery at the scales and have it checked.

Deliveries of more than 1,000 kg need to be accompanied by a completed waste wood certificate.

For the sample waste wood certificate see here: Waste wood certificate
