Bio-Process Group has developed a proprietary ‘Low Temperature Steep Delignification’ (LTSD) technology that reduces capital and operating costs associated with pulp production and improves yield in non-wood pulping. The process was originally designed and developed as a pretreatment for biomass in the production of cellulosic ethanol over ten years ago. Upon realizing that the process created a very high quality fiber the process has been further developed and optimized over the past five years for making ag-pulp. Our design is zero effluent, low water and energy use, and mostly done under 100 degrees C(atmospheric pressures). Testing the LTSD process on a wide variety of biomass sources has proven the technology to be quite robust.
One area we have focused on is dedicated bio-mass crops. We have run large trials on Miscanthus, Arundo, Switchgrass, and Bamboo with good success.
Bamboo is a very hard substrate which can be converted to a nice high quality long fibered pulp.
Miscanthus is a fast growing grass identified as a possible 'high producing biomass' for celluosic ethanol, but also produces a nice pulp.
Arundo is a fast growing cane type biomass which can be harvested several times a year under correct growing conditions. It also makes a nice pulp as per photos below.
