Next-Gen Feedstocks- Breeding, Engineering, Handling

Plant-based feedstocks are starting materials for many biomass conversion or bio-based production process, however C1, syngas, and other non-biomass feedstocks are gaining increasing attention in commercial operations. This track focuses on advances in the manipulation, analysis, and collection, storage and handling logistics of biomass-based and alternative feedstocks. Engineering or selection of feedstocks to enhance thermal, chemical, enzymatic or microbial plant cell wall deconstruction reaction rates or yields are of particular interest.

The following lists non-exclusive topics of specific interest for this track:

  • Genetic and environmental manipulation of biomass feedstocks for improved conversion traits

  • Analytical methodologies for characterization of feed stocks in the laboratory or field
  • Development of captive, waste-based, and alternative feedstock conversion technologies
  • Biogas, syngas, CO2 fixation, natural gas, and other non-biomass derived feedstocks
  • Comparative analyses or evaluation of the performance different feedstocks in preprocessing and/or conversion processes
  • Geology, geographic, climate, and soil impacts on biomass recalcitrance
  • Enhanced agricultural, silvicultural and land-use practices for growing and harvesting renewable feedstocks more efficiently
  • Harvesting, storage, pre-processing and transportation of feedstocks, particular ly in supply logistics for commercial plants

Engineering Operations for Biomass Processing

A commercial biomass conversion plant encompasses a wide array of unit operations designed to make feedstocks more manageable and susceptible to conversion, as well as conversion and product recovery technologies. These operations have a huge impact on the Life Cycle and Technoeconomics of plant operations and preference will be given to abstracts addressing these aspects. Of particular interest are recent advances and novel technologies that decrease costs by increasing rates and yields of conversion products or by lowering equipment (CAPEX) and operating (OPEX) costs.

Specific areas include:

  • Mechanical, thermal, and chemical methods to fractionate plant-materials into their major constituents (cellulose, hemicellulose, starch, other polysaccharides, lignin)
  • Novel and improved unit operation (reactors, fermenters, separation) designs for economic commercial-scale bio-based production
  • Improvements in pilot, demonstration- and commercial-scale operation of integrated bio-based chemicals and/or fuels production, both technical performance characterization and improvement and economic assessment
  • Development of new or improved on-line (real time) measurement of bioprocess performance

  • New or improved processes for separating or cleaning up intermediates and recovering products
  • Process designs, techno-economic assessments and life-cycle analyses of integrated bio-based production

Deconstruction, Fixation, and Bioproduct Formation

Enzymatic and chemical catalysis are central to biological production of fuels and chemicals from renewable plant-based feedstocks, whether through deconstruction of lignocellulose, conversion of biomass-derived intermediates to products, or via autotrophic carbon fixation. This Topic Area highlights enzyme and chemical catalyst discovery, chemical & physical characterization and kinetic analysis, protein engineering, and structure- and model-driven understanding of catalytic reaction mechanisms. Of particular interest are advances in improving and understanding holistic enzymatic deconstruction of biomass, the application of petrochemical-based catalytic cracking technology to biomass conversion, and chemical and thermal processes for upgrading biomass-derived compounds to higher value products.
