摘要

Imagine that you are tasked with improving the waste management system in a country or region that already accomplishes advanced standards in terms of recycling and recovery, as well as of landfill minimisation. What are the opportunities for improvement? Is it a matter of continuous progressive optimisation, or there is room for game-changing solutions? Well, let us take a step back and introduce the framework of this challenge. Like for many other sectors, the management of waste varies widely in different parts of the world, moving from situations where the improper management is cause of illnesses, premature deaths and major environmental degradation to situations where companies are embracing advanced circular economy strategies and earning profits from the recovery of waste. In the former, stopping the leakage of waste in the environment by securing open dumpsites is the top priority; this would limit the pollution of underground and surface water by uncontrolled leaching, the severe air pollution due to uncontrolled burning, the littering into water bodies, etc. In the latter, the industrial strategies based on waste recovery might benefit from further interaction with the producer of materials that will become waste, but on the other hand, they must be able to cope with strategies of waste prevention, thus to discourage continuous and growing waste generation. Such approaches have already become critical in some countries that heavily rely on waste incineration but might in turn involve other increasing waste streams, such as food waste.
