METHODS FOR PRODUCING BIOMASS-BASED FUEL WITH PULP PROCESSING EQUIPMENT

Title:

METHODS FOR PRODUCING BIOMASS-BASED FUEL WITH PULP PROCESSING EQUIPMENT

Document Type and Number:

WIPO Patent Application WO/2010/093812

Kind Code:

A3

Abstract:

A method for mitigating the costs of establishing a biomass-based pellet manufacturing plant includes identifying an existing pulp processing plant, obtaining permission to access and convert the pulp processing plant, and converting the pulp processing plant for manufacture of biomass-based pellets. Converting the pulp processing plant may include installing a pellet mill in the pulp processing plant, re-routing output from a pulp digester, such that the output enters the pellet mill, and bypassing unnecessary equipment. Biomass-based pellets may be manufactured in the converted pulp processing plant by liberating lignin from biomass-based feedstock via pulp digester and pelletizing the biomass-based feedstock and the liberated lignin to form the biomass-based pellets.
