The iCRAB Project

Biorefining produces higher value products than other routes for biomass utilisation but often involves more processing with additional costs. To ensure economic sustainability all inputs need to be converted to useful products with minimum processing steps. Crustacean shell, the major by-product from scampi, prawn and crab meat processing contains 20-30% chitin. Chemically extracted chitin is …

The Value Chain of Biomass Waste

According to the well-established waste hierarchy model of sustainability the re-use and, below re-use in the hierarchy, the recycling of manufacturing waste is a more environmentally sustainable approach to the handling of waste than its disposal or conversion to energy (e.g. biogas). For waste biomass this delineation in the waste hierarchy is not so clear. This is …

Chitin and Chitosan

Chitin is the second most abundant polymer in nature after cellulose. It is a sustainable natural resource that is ubiquitous but still relatively under-exploited commercially. Chitin is a structural polysaccharide found in the cell walls of fungi, the cuticle of insects, shells and the exoskeleton of crustaceans – its main commercial source. In crustaceans, single-strands …
