Material & Natural features

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.
