In recent years, amide the rise of fossil fuels price, using of renewable energy resources, one of which is biomass, is becoming increasingly important.

One of the most efficient ways for organic wastes processing is the process of fast pyrolysis. The technology allows processing of biomass in such products as combustible gas, char and pyrolysis liquid – biooil.

Analysis of existing enterprises shows that a key aspect of enterprises for biomass wastes processing is the limited availability of feedstock in a particular geographic area. Increase of feedstock delivery distance is also increasing its price. When the distance exceeds some value, biomass processing is becoming unprofitable. Current technological solutions (circulating fluid bed, fluid bed, and rotating cone) are oriented to large-capacity processing.

The authors hold another opinion about lignocellulosic biomass processing. Our approach allows decentralized processing with increase of biomass energy density and, in near future, integration to current energy systems and petrochemical industry.

At the present time our specialists are working on creation of effective technology of fast ablative pyrolysis. The technology will be realized in mobile transportable modules with capacity up to 25 tons per day. These modules will allow processing of wastes from small and medium agricultural and forest enterprises into biooil.

Now we have pilot plant for lignocellulosic biomass processing by fast ablative pyrolysis. We are working on creation of larger demonstration plant.
