Dr. Heidi Sieverding
Associate Professor of Practice

Providing integrated technoeconomic and life cycle analyses (TEA and LCA) is a key component to supporting bioprocessing and bioproduct development from laboratory research through to commercialization. Heidi has expertise in evaluating the sustainability of bio-products and their production systems using life cycle analysis. This includes developing life cycle inventories and evaluating the sustainability of feedstock production, supply chains, processing systems, product distribution, and waste disposal. Depending on project needs, Heidi collaborates with Greg Opdahl at Dakota BioWorx to provide combined TEA/LCA reports to clients.
