What is the right level of recycling of plastic waste?

One of the main objectives in waste management is the recycling of waste and thereby making use of resources contained in waste to save primary resources and reduce the environmental impact of all activities involved in making primary resources available for the production of goods. Enabling recycling starts with (1) design of products for recyclability, (2) collecting the end-of use material (often called waste), (3) processing the waste in order to get intermediate secondary materials that can substitute primary materials, and finally (4) the actual utilisation of these secondary resources to produce new products. Depending on the material to be recycled and type of waste looked at as well as the prevailing structures of waste management in different parts of the world, the processes involved and opportunities at hand differ very much and need a comprehensive understanding of the situation to enable optimisation of a system that answers the question posed in this article’s title. This special issue of Waste Management & Research focuses on plastic waste and this is one waste stream that warrants further study.
