Ethanol from Biomass Wood Energy

Sep 05, 2019 Environmentally speaking, ethanol has both low carbon and sulfur emissions as well as very little particulates. The large-scale production of ethanol from woody biomass or lignocellulosic biomass, in particular, is important because it would mean less waste when producing biofuels from feedstocks such as corn and cane.

Producing and burning ethanol results in emissions of carbon dioxide (CO2), a greenhouse gas. However, the combustion of ethanol made from biomass (such as corn and sugarcane) is considered atmospheric carbon neutral because as the biomass grows, it absorbs CO2, which may offset the CO2 produced when the ethanol is burned.

AE493/AE493: How Ethanol Is Made from Cellulosic Biomass

Production of ethanol from sugar and corn feedstocks is often viewed as competing with food production and increasing prices of food and fuel. Therefore, ethanol from cellulose-based biomass has been attracting interest because using non-edible biomass as a feedstock to produce ethanol minimizes competition with the food industry. In fact, a US

The Future of Ethanol: Cellulosic Ethanol University

Traditional ethanol production grinds corn kernels to release the starch, which is then fermented. Cellulosic ethanol production starts with the biomass or plant materials and breaks down the cell wall to release the starch or sugars in the plants leaves and stems. These simpler compounds are then fermented into ethanol.
