This question is related to garbage valorisation. In producing time, materials can be eroded, every three situations (solid, liquid, gas phases). eroded materials don't be considered in any cost statements. But, this situations, direct or indirect, reveal two tips of costs: waste disposal or recycling both internal and external. we focus on internal recycling which is physicallly appears but no value materials.
Hello,
If you are dealing with material linked to the construction market, there is the new European Standard EN15804 which provide you the methodology to take into account the end of life and the recycling potential of each material. I made some publications on that, you can check. hope it will help.
The value of valueless material (Waste of any form) is in the differential between the cost of conversion and the value the application of the converted material. There can be significant ranges in this value as the application and local economics dictate. Attached are three papers showing the ranges in value that a waste stream (organic waste biomass) can have.
Cannot give a concise and generic answer, but definitely this is a very interesting research question. Here at the University of Leeds we have a substantial research programme called "CVORR: complex value optimisation for resource recovery", which includes but also goes beyond monetary values. You can get a feel about the scope of our on-going work on the attached conference paper. So keep an eye for future developments and publications in this area.
