Biopulping process
WebLignin and hemicelluloses are removed selectively during early growth of WRF that produces enriched cellulose, known as selective delignification. Biopulping is considered … Webcommercial operation of the process. Based on the electrical energy savings and the strength improvements, the process economics looks very attractive. Several independent economic evalua tions of biopulping have now been completed by both university and industry economists and engineers and are in agreement.
