Lignor, like other wood products store carbon. However, being a hardwood it tends to store more. ESB®, ESL® and CLST™ offers the following carbon storing benefits:
- The carbon released from ESB®, ESL® and CLST® production is less than for kiln dried softwood
- The carbon released during ESB®, ESL® and CLST® production is several orders of magnitude less than steel, glass and aluminium. Every tonne of cement manufactured creates 900kg of greenhouse gas emissions.
- The carbon stored in ESB®, ESL® and CLST® is greater than the other Engineered Wood Products by up to 3 times
Lignor EWP when used in house construction to substitute for conventional building products such as concrete, steel, bricks, plastics and aluminum would save approximately 25 t CO2 being released per house . Equivalent to driving a Toyota Prius for .
Net carbon stored in Lignor products is 1-3 times more than softwood EWP. This is due to:
- Less evaporation of water /m3 in eucalyptus and Lignor products vs softwoods Engineered Wood Products.
- Lignor’s biomass has up to 3 times more calorific value than softwood biomass.
- Plantation Eucalyptus trees can be much faster growing, eg. with a sustainable harvest at 8-12 years vs plantation softwoods, leading to faster carbon storage within the plantations and wood products over time. Furthermore, eucalyptus grows up to 60m3/ha pa in the sub-tropics compared to timber in say Northern Scandinavian boreal forests which grow at 1m3/ha pa in good conditions or even less, as low as 0.1m3/ha pa in poor conditions.
Thus Lignor products lead to much more virtuous carbon storage per annum than softwood EWP per m3.
