Process Design and Improvement for Biorefinery Systems
Bio-Process Group (BPG) is a process engineering and contract research practice founded in 1984 at Purdue University, focused on developing profitable process technologies for industrial biorefinery systems. Operating through two specialized branches-Bio-Process Innovation (focused on applied biotech research and development) and Applied Bio-Process (focused on process design and engineering packages)-it provides contract research, feasibility studies, techno-economic process modeling, construction and commissioning support, owner's engineering, and permitting assistance. BPG assists clients in converting biomass, whey, waste paper, and other organic waste streams into high-value fuels, chemicals, and co-products.
