| Research Abstract |
Recycling is currently one of the key issues for many industrial firms. It is obvious that the goal of 'zero-emission' is impossible in view of thermodynamics and the practicalities of engineering. The only way to achieve true sustainability on the planet, therefore is to set industrial activity to within some equilibrium magnitude of energy supplied to the planet by the solar system. Engineers, more often than not, fail to consider aspects of their design that impact on the global balance of a particular consumable resource, but instead concentrate on more local aspects of consumption and price. While it is true that many virgin materials have a world market price such as copper, zinc, lead and aluminum, this is not necessarily the case with recycled materials. This stems from the fact that the cost of recycling is very much dependent on local labor costs, as the collection and sorting of recyclable materials tends to be labor intensive.
Although the concept of Life Cycle Assessment (LCA) is very nice, there have been some problems to work well. In the present project, man-made resources are defined and recycle systems and techniques of metals in the man-made resources have been investigated from a view point of physical chemistry as a basic research. Most base metals such as Fe and Cu and a few rare metals such as Ni are handled in this project.
