回顾了通过可回收材料的基本发展以及控制回收利用的技术来实现循环型社会的运动。近年来，以实现循环利用为目标的各种聚合物的生产和技术取得了进展。例如，商品塑料的升级回收，工程塑料的选择性转化，各种聚合物在超临界流体中的选择性解聚，使用可逆反应的交联-解交联控制以及生物质可回收聚合物的开发。尽管这些聚合物和技术在有效性、效率和精度方面取得了长足进步，但仍需进一步改进，以满足容器、包装、家用电器和报废车辆回收的负责任可持续系统的实际要求，所有这些都符合日本的回收法律。
The movement toward a recycling-based society through the essential development of recyclable materials alongside technologies for controlling recycling is reviewed. Recently, there has been progress in producing various polymers and technologies with the aim of achieving circulative utilization. For example, the upgrade recycling of commodity plastics, selective transformation of engineering plastics, selective depolymerization of various polymers in supercritical fluids, crosslinking–decrosslinking control using reversible reactions and developments in biomass-based recyclable polymers. Despite great strides taken in the effectiveness, efficiency and precision of these polymers and technologies, further improvements will be required to meet the practical requirements of a responsible sustainable system for the recycling of containers, packages, electric household appliances and end-of-life vehicles all of which are operated in compliance with the recycling laws of Japan.
