MC ALOON, ANDREW /et al/ | Colorado [ESTADOS UNIDOS] : National Renewable Energy Laboratory | Technical Report | 2000The mature corn-to-ethanol industry has many similarities to the emerging lignocelluloseto-ethanol industry. It is certainly possible that some of the early practitioners of this new technology will be the current corn ethanol producers. In orde[...]
