General objectives
05/06/2018 3
Achieve favourable techno-economic and environmental performances
for the production of 2G ethanol in small-scale industrial plants.
Identify feedstock with sustainable and reliable supply conditions for the
evaluation and selection of business cases in Latin America and Europe.
Provide all the necessary data for the selected business cases so that
the new technology can be realistically evaluated and the project scaled-
up to demonstration level.

New pretreatment process of the biomass
• Performance of pretreatment and enzymatic impregnation / pre-hydrolysis in one reactor.
• All the operations necessary to increase the access of the hydrolytic enzymes to the carbohydrates
(deconstruction, defibrillation and depolymerisation) and to start the solubilisation of sugars are carried out
in a twin-screw extruder.

Extrusion relies on the force exerted by the tight rotation in the same direction of two identical
intermeshing screws mounted on a splined shaft, inside an eight-shaped stationary barrel.

BABET-REAL5 new business model
2G Ethanol business models under development in the world
Big size production plants: 50-100,000 m3 Ethanol
Requires: 200-350,000 t dry biomass in small catchment areas
High investment: 100-200 M€ or plus
Not applicable to regions not able to supply and concentrate such quantity of biomass
Big investment difficult to achieve without significant public funding support
Find solutions
for regions that cannot provide such high amounts of concentrated biomasses
for producing ethanol without needing major public funding
Suitable for rural development, decentralized energy production & the autonomy of the territories
New approach of business models based on small-size industrial plants economically
viable from 30,000 t/year DM biomass collected in small catchment area
(10,000 m3 Ethanol)
