Waste exchanges represent another way of reducing waste disposal volumes for waste that cannot be eliminated. Ship to point of use This involves making deliveries of incoming raw materials or components direct to the point where they are assembled or used in the manufacturing process to minimise handling and the use of protective wrappings or ...

However, this formulation, while well-suited for handling emissions or resource use, encounters challenges when dealing with waste.
