Related Projects: Textile Waste Recycling by Biological Methods

In Hong Kong, there are around 217 tons of textile waste generated daily, this accounts for 1.6% of total municipal solid waste (MSW). Fifty-two percent (52%) of the MSW generated is dumped into landfills. It is estimated that by 2020, all the current landfill sites in Hong Kong will be exhausted. Exploiting textile waste generated by the clothing and textile industry for chemical and material production could create integrated, sustainable and bio-based processes. In this project, we aim to conduct the feasibility studies of textile waste recycling by biological method. We intend to recover fermentable glucose and polyester (PET) fibre from textile waste via bioprocessing. This will contribute to a novel approach of textile waste treatment, especially the pretreatment and the enzymatic hydrolysis process. In addition, the feasibility of re-spin PET fiber recovered from the textile waste will be conducted.
