  • Project Sponsors: Defra Renewable Materials LINK programme & HGCA
  • Project Title: Production of Bioalcohols From Lignocellulosic Waste Materials Produced in the Agri-Food Chain

The challengeCellulose microfibrils

Waste lignocellulosic biomass is produced in abundance throughout the global agri-food chain. Its efficient conversion to biofuel can reduce dependence on fossil resources, increase energy security and reduce competition of energy crops with the food industry.


Lignocellulose is derived from plant cell walls. It comprises a complex of carbohydrate polymers (cellulose and hemicellulose) tightly bound to lignin. Its structure makes it resistant to enzymatic degradation – a challenge that must be addressed in order for it to be broken down into simpler sugars and then fermented into bioalcohols.


All this must be achieved against a background of rapidly evolving issues, including climate change, energy balance, the size of the carbon footprint and engine performance.

The project

The 4-year research programme, funded by the Defra Renewable Materials LINK programme & HGCA, aims to develop, evaluate and support the commercial exploitation of tailored approaches for converting different sources of agri-food-chain waste lignocellulose into so-called second-generation bioalcohols for the automotive industry.
