The next generation sustainable Biondoil bio-ethanol refinery
Biondoil develops Bio-Refinery concepts on industrial scale exploring green-field and brown field opportunities. The cornerstone
of our projects is the conversion of lignocellulose biomass into bio-ethanol. Currently the business driver in Europe is the
RED2 renewable energy directive encouraging oil companies to mix biogenetic material in their fuels.
There are two proven technologies to produce bio-ethanol on a substantial scale, basically using different pre-treatment systems:
Pre-treatment based on steam explosion:
- Pre-treatment consist on the smart cooking of biomass using only water and steam (no chemicals are added), operating with
optimized conditions and temperature, pressure and residence time.
- This stage creates large volume of water residue which is cleaned and recycled.
Pre-treatment based on fractioning with biosolvents:
- Fractioning is a separation process in which enzymes is divided during a phase transition, into a number of smaller quantities in
which the composition varies according to a gradient.
- Due to rapid impregnation of the biosolvent into the raw material, cooking takes place quickly and at low temperature. As the
delignification is highly selective, the yield and quality of cellulose, hemicellulose, and lignin are optimal.
With both technologies’ enzymes are used to remove or modify hemicelluloses and lignin protecting the cellulose in the plant cell
wall. Besides extracting a pure cellulosic portion this will enable further valorisation of underutilized biomass fraction to
provide high value bio-alternatives of oil-derived chemical building blocks.
