Although mechanical recycling methods are in place for plastics such as polyethylene terephthalate (PET), the physical and chemical properties are significantly compromised after a number of cycles, and they eventually reach end-of-life and end up in landfill. Chemical recycling is a collection of emerging innovative technologies that transform plastic waste into base chemicals, monomers and feedstocks. This approach complements mechanical recycling, bridging the gap between waste management and the petrochemical industry. However, with regard to the seven types of recyclable plastic, there is currently no clear overview of the suitable techniques. Therefore, we aim to provide a critical perspective on the suitability of different chemical processes towards recycling different types of plastic, by combining fundamental knowledge and research advancements in recent years, with an emphasis on assessing their environmental and economic impacts.

However, the practical implementation of this technique is hindered by issues such as structural fragility, low operational stability, and limited recyclability. Recently, reticular framework materials (RFMs), including metal–organic frameworks (MOFs), covalent organic frameworks (COFs), and hydrogen-bonding organic frameworks (HOFs), have garnered significant interest as functional scaffolds for integration with photoenzymatic systems. These RFMs provide protection and enable reusability for homogeneous photoenzymatic systems. Due to the immense chemical and structural tunability derived from their organic and inorganic building units, RFMs offer opportunities to develop effective and efficient integrated photoenzymatic enzyme/RFM systems. In this review, we first discuss recent progress in RFMs and their applications in enzyme immobilization, as well as categories of photoenzymatic reactions. We then summarize design strategies for RFM-based photoenzymatic systems.
