Iowa State to manage biorefinery projects for new Manufacturing USA Institute

Green Car Congress

Iowa State University will bring its expertise in biorenewable technologies and pilot plant operations to the country’s 10th Manufacturing USA Institute. The so-called autothermal process increases the rate that biomass can be converted to products, allowing construction of smaller and simpler reactors suitable for modular systems.
