Lignin Bioaerogel AKL - green high-performance insulation

Our lignin bioaerogels are derived from non-food biomass and by-products from agriculture, forestry, and marine industries.

Thanks to our energy-efficient production technology and green raw material base, we anticipate an excellent sustainability footprint footprint.

With our lignin bioaerogels, we are setting new standards in sustainable material technology, offering solutions for numerous industrial applications.

Lignin Bioaerogel AKL is 100% bio-based and super-insulating. Lignin Bioaerogel AKL enables conversion of the side stream lignin into a high-performance material.

Lignin Bioaerogel AKL is still in development. Sample quantities are available at lab scale.

Typical properties

Thermal conductivity (at 10°C, particle bed): 0.021-0.023 W/(m*K) (hydrophilic)

Particle size: 1-2 mm

Density: 50-100 kg/m³ (adjustable)

Internal surface area: 250-350 m²/g

Pore volume (< 100 nm): 1.9 cm³/g

Porosity: >90%

Hydrophilic, not water-stable, sensitive to humidity

Lignin Bioaerogel AKL can be ground into powder and compressed into board form. In the laboratory, we have achieved a record low thermal conductivity of 0.017 W/(m*K), making it ideal for high-performance insulation.
