【题目】CThere are energy saving to be made from all recyclable materials,sometimes huge saving. Recycling plastics and aluminum. forinstance, uses only 5% to 10% as much energy as producing newplastic or smelting(提炼) aluminum.Long before most of us even noticed what we now call "the...
precipitation formation was found to be Fe3+<Fe2+<Dy3+<Nd3+<Pr3+.Fe3+ was selectively precipitated by the precipitation titration method.Nd metal and a part of oxides in electrodeposits were identified by XPS.The recycling process of RE from VCM wastes was proposed as a saving energy method...

This is one of the best yet most ignored reasons.If most people recycled metal and metal items regularly, it would be less costly to produce metal in terms of energy and the ore required.This will mean that the actual cost of buying metal will be reduced, saving you some money. ...
Battery green recycling routes are responsible for the wide-spread use of SSLBs due to minimizing environmental contamination, reducing production costs, and providing a sustainable solution for resources, e.g., saving rare earth elements (La, Ta, etc.). Herein, a solid-state recycling strategy ...
The energy-saving strategy for air-preheating mode is to use the residual heat of the system to –preheat the air entering the burner for combustion. In the basic method (BM), heat from high-temperature parts directly exposed to the environment in the system is wasted and the residual heat...
The energy received on Earth from the Sun is plentiful and totally renewable. Therefore, its use has attracted the interest of mankind since ancient times [1,2]. Nowadays, the direct conversion of solar energy into electricity seems to be one of the most feasible future solutions for the incr...
