Helping Landowners with Waste Wood While Improving Agribusiness and Energy
Every year, millions of tons of wood waste produced by commercial timber harvests and forest restoration burn in open piles that send untold amounts of carbon dioxide into the atmosphere. Is there a more feasible and economical way to utilize this waste wood? Follow this link to learn more: http://www.nsf.gov/discoveries/disc_summ.jsp?cntn_id=126349&org=NSF&from=news

Woody Biomass Sulfite Pretreatment to Overcome Lignocellulose Recalcitrance for Biofuel Production (SPORL) – Patent
UW-Madison researchers have developed an improved pretreatment process for robust conversion of biomass. This process, known as Sulfite Pretreatment to Overcome Recalcitrance of Lignocellulose (SPORL), reduces the energy consumption needed for size-reduction processes, required before enzymatic hydrolysis, by more than tenfold.
