Material & Natural featuresNatur


In line with the motto "reusing global resources" we at Oberpfaelzer Biotech have developed products that take "ecology" and "transience" as their focal points.

Lignin Extraction

The starting point in developing a material from renewable raw materials that is thermoplastically processable is lignin, which is the second most abundant polymer in nature after cellulose. It forms in tree trunks around cellulose fibres. Lignin is a by-product of the pulp industry with more than 60 million tonnes being accumulated every year worldwide.

By mixing lignin with natural fibres (wood, flax, hemp or other fibrous plants) and subjecting it to heat, a fibre composite material is produced.


Ecological advantages
As they are formed using renewable raw materials, these materials have very positive environmental properties:
  • A closed CO2 cycle, biodegradable / compostable
  • An excellent balance of ecological and energy expenditure
  • Not starch-based
  • 100% natural material and therefore not a WPC (Wood-Plastic-Composite)
  • Environmental certificates in line with: EN71, EN1186, ENV13130, DIN 51731
  • Proven biodegradability verified in accordance with: DIN EN ISO 14851:2004
Advantages of liquid wood

The crucial factor favouring liquid wood is the technical advantage it brings as a high-quality construction material. As liquid wood consists of wood components (lignin and fibres), it has similar mechanical and thermal properties to natural wood.

  • White mould fungus is one of the most effective lignin decomposers and is responsible for breaking down wood
  • High dimensional stability in heat
  • High rigidity
  • Unlike natural wood, the material does not have different properties lengthways and widthways
  • Easily achievable, “wooden”, snap-on fastenings.
