Abstract

Biorefinery models which incorporate the utilization of waste as a bioresource, support the transition to a circular bioeconomy. This chapter discusses some key aspects of circular waste-based biorefinery development, including the recirculation of resources in terms of their reuse and recycling, as well as requirements and challenges for the transition from a linear economy to a circular economy. The circular economy concept underpins the green chemistry and bio-processing approach which involves the use of (bio-)benign renewable resources, including waste resources in benign reaction media, to develop processes and products in an environmentally friendly manner. In the context of a bio-based economy, a major concern for the adoption of a circular economy is exploring the role of renewable resources. The chapter describes case studies of food waste and textile waste-based biorefineries, particularly in the context of Hong Kong, for the production of high value-added products such as chemicals and materials.
