A Total Project Solution based on:

1. Agronomy: Field experimentation and best energy crops identified and characterized;

2. Biomass Pre-Treatment and Viscosity Reduction: Continuous process developed and piloted to produce cost-effective and clean fermentable sugars;

3. Hydrolysis and Fermentation: Unique hybrid SSCF process scheme yielding high ethanol concentrations.

PRO.E.SATM Technology: From Biomass to Sugar

Without use of chemicals;

Optimizing C5 and C6 sugar extraction;

Minimizing the formation of by-products/inhibitors;

Using continuous equipment enabling design for

large scale plant;

Minimizing CAPEX and OPEX.

The Continuous Pilot Plant: How it operates…

Biomass agnostic;

No biomass drying / grinding required;

Low level of inhibitor (lower then in P.O.C.);

No use of chemicals (only steam is added);

Reduced enzyme loads;

Rapid liquefaction of the solid material;

High solid concentration (>40%) in the hydrolysis step.

Biomass: Our Experience at Pilot Plant

PRO.E.SATM technology is flexible in feedstock supply: possibility to treat worldwide crops;

Several biomasses were evaluated and tested as potential feedstock for the PRO.E.SATM technology:

Internal analysis according to Chemtex methods

Pre-Treatment Section: Biomass Type

High feedstock flexibility

Energy crops:

Arundo donax (giant reed);

Miscanthus giganteus;

Panicum virgatum (switchgrass).

Agricultural and industrial residues:

Wheat straw;

Rice straw;

Sugarcane bagasse.

Woody species:

Eucalyptus;

Poplar,

Internal data tests at pilot scale

Differences in yield (4 to 5 tons dry biomass/tons EtOH) index mainly depends on feedstock composition;

It is possible to reduce the yield variability optimizing the process condition.

Hydrolysis and Fermentation

High solid concentration enzymatic hydrolysis is needed to guarantee the economics of

ethanol recovery through distillation

The lifecycle performances of bioethanol produced through Chemtex technology at a full industrial scale have also been estimated by means of the GREET model;

Scale benefits will allow a further improvement of the bioethanol environmental profile.
