Design of a crushing and agglomeration process for manufacturing bagasse charcoal
In Haiti, wood and wood charcoal are common fuels for cooking. This practice has contributed to deforestation, leading to erosion and fatal floods. The availability of charcoal made from a different source other than wood, such as agricultural waste, might provide Haitians with an alternative, more …

Life cycle assessment of dewatering routes for algae-derived biodiesel processes
Biodiesel derived from algae is considered a sustainable fuel, but proper downstream processing is necessary to minimize the environmental footprint of this process. Algae is grown in dilute liquid cultures, and achieving the low water contents required for extraction represents one of the greatest …
