During the last years the worldwide legal framework has stimulated the biofuel development, causing their production and use to be exhaustively studied. Biodiesel has been mostly produced in European countries, but the agronomic potential of the Latin-American countries has led the effort toward...

Coffee cut-stems (CCS) represent a promising candidate for fuel ethanol production in tropical countries because of their high availability and high biomass yield per hectare. In this work, pretreatment of this agricultural residue with dilute sulfuric acid and liquid hot water (LHW) was...

In this paper a techno-economic analysis for bioethanol production in Africa for Tanzania case is presented. It is shown conversion pathways from sugar cane juice and molasses, at three levels of technological schemes, where the first one includes a selection of widely conventional technologies,...
