SUSTAINABLE TREATMENT OF WASTE USING RECYCLED CHITOSANS (STOWURC)

STOWURC项目旨在开发可持续的材料和工艺，利用海鲜行业的废物处理废水，并从印刷电路板(PCB)和相关行业回收金属。英国印刷电路板行业对该国具有重要的战略意义，但其化学流程会产生处理成本高昂的废物产品。螃蟹和其他甲壳类动物的壳是一种被称为壳聚糖的材料的来源，它可以吸收金属。因此，它们有能力回收印刷电路板制造废水中的金属。英国的海鲜行业产生了大量的贝类废物，该项目正在利用这些废物生产壳聚糖材料，这种材料可以可持续地处理印刷电路板制造商和生产类似类型含金属废物产品的公司产生的废水。项目合作伙伴已经确定了国际上对使用多氯联苯制造商的壳聚糖材料的兴趣，在包括表面工程在内的其他部门也有更大的应用。处理蟹壳通常很昂贵，这个项目将使它们成为有价值的原材料。

The STOWURC project is aimed at developing sustainable materials and processes that use waste products from the seafood industry to treat effluent and recover metals from the printed circuit board (PCB) and related industries. The UK PCB industry is strategically important to the country but its chemical processes can generate waste products that are expensive to treat. The shells of crabs and other crustaceans are a source of materials known as chitosans which can absorb metals. They thus have the ability to recover the metals that are found in PCB manufacturing effluent. The UK's seafood industry generates large volumes of shellfish waste and the project is using this waste to produce chitosan-based materials that can sustainably treat the effluent produced by PCB makers and companies producing similar types of metal bearing waste products. The project partners have identified international interest in using chitosan-based materials from PCB manufacturers and there are also much larger applications in other sectors, including surface engineering. Crab shells are typically expensive to dispose of and this project will enable them to become valuable raw materials.
