Berkeley Lab creates six blends with MSW and biomass

In California, in a new study published in the journal ChemSusChem, researchers at Berkeley Lab created six blends that combined MSW items (non-recyclable paper and grass clippings) with biomass (corn stover and switchgrass). Using an ionic liquid-based process, they converted these blends into methyl ketones, which are chemical compounds that can be used as diesel fuel precursors.

This is the first report on the conversion of MSW to methyl ketones using an ionic liquid process, an efficient biomass pretreatment process that is becoming more sustainable. The research was a collaboration between the Joint BioEnergy Institute and the Advanced Biofuels and Bioproducts Process Development Unit (both established by the Department of Energy and based at Berkeley Lab), where researchers scaled up one of these blends 30-fold and are currently attempting to scale up the process even further.
