Biorefinery was an effective way to convert biomass resources into energy and diversified valuable biomass products. It was also an effective way to high-value utilizeraw material and resource "three wastes" (waste gas, waste water and waste industrial residue). Paper industry provides an important platform for developing biorefinery. This paper emphasizes several feasible models in conjunction with traditional pulp & paper industry and biorefinery, relevant technology application and development trend. ©, 2015, China Technical Association of Paper Industry.

The washing and bleaching were designed to use integrated technology and its equipment, such as the extrusion-diffusion replacement washing, the closed hot screening and fans defoaming etc in a reed pulp mill. Compared with the traditional black liquor extraction technology, the integration technology significantly improved extraction rate, concentration and temperature of the black liquor. It provided a practical basis for effectively optimizing the extraction of black liquor in straw pulping process.
