The Cellulose Pilot and Processing Lab (CPPL) is a biorefinery research and commercialization facility operated as a university-industry partnership between the Wisconsin Institute for Sustainable Technology (WIST) and American Science and Technology Corporation (AST). Both AST and WIST operate facilities comprised of processing units for production of pulp, cellulose-sourced sugars, bioplastics, and green chemicals. 

The AST facility houses a two-ton-per-day pilot biorefinery to process forest and agricultural biomass into sugar, lignin, and green chemicals using processes developed and patented by UW-Stevens Point.

Building from central Wisconsin’s powerful economic engine of timber and agricultural processing, and the innovative research at WIST, the CPPL brings together scientists, academics, and entrepreneurs to support existing bioprocessing industries in developing and adapting new bio-based technologies.  The ultimate goal is to accelerate the development of new renewably-sourced products, and provide a much-needed experimental and research facility.
