Our Vision

Our Mission

The global leader inbiomass conversion technology

Reducing GHG emission inplastic production

How does Lignum contribute to UN's SDGs?
‧Lignum technology contributes to the UN’s sustainable development goals.

SDG 2

We produce SSEIF ® Biofiller fromnon-food biomass.

SDG 11

SDG 13We do not emit greenhouse gas
because our feedstock is producedby photosynthesis.

SDG 14,15

Our innovative technology makesbiorefinery industry commercially
viable, creating job opportunities.

Our eco-friendly technology
contributes to making our planet clean
by converting lignocellulosic biomass
into biodegradable products.

PRODUCTS
SSEIF®

SSEIF® Biofiller was designed to enable manufacturers to make lightweight plastics. SSEIF® Biofiller
shows excellent dispersion, MI, and surface properties in the processes of extrusion, injection and blowing.
