Pyrolytic Behavior of Major Biomass Components in Waste Biomass

Pyrolytic sugars from cellulosic biomass.

Depolymerization of cellulose offers the prospect of inexpensive sugars from biomass. Breaking the glycosidic bonds of cellulose to liberate glucose has usually been pursued by acid or enzymatic hydrolysis although a purely thermal depolymerization route to sugars is also possible. Fast pyrolysis of pure cellulose yields primarily the anhydrosugar levoglucosan (LG) whereas the presence of natur...

Polyhydroxyalkanoates production from waste biomass

Polyhydroxyalkanoates (PHAs) is a group of biopolymers that are extensively researched for such purpose due to the biocompatibility with mammal tissue and similar properties with conventional plastic. However, commercialization of PHA is impended by its high total production cost, which half of it are from the cost of pure carbon source feedstock. Thus, cheap and sustainable feedstocks are pref...

Biodiesel Oil Derived from Biomass Solid Waste

Oils of a significant value both as fuels as well as for cosmetic applications can be extracted from the fruits of the jojoba plant. After extracting the oil, the remains of the fruit can still be further utilized as a solid fuel in furnaces or feedstock to animals. In the present work, the solid waste jojoba remains have been processed chemically to extract more biodiesel oil. The physical and...

GASIFICATION vs COMBUSTION OF WASTE/BIOMASS IN FLUIDIZED BED REACTORS

This paper presents a comparison of commercial fluidized bed gasifiers and combustors used to recover energy from municipal solid wastes and biomass. The work reported here is excerpted from four case studies prepared for the International Energy Agency’s Bioenergy Agreement, under Task 23 (Energy from Thermal Conversion of MSW and RDF, 1998-2000) and Task 36 (Energy from Integrated Solid Waste...
