Research and development of processes and operation of demonstration plants
Aluminum recycling without salt: Tilting rotary furnace plasma; Stationary plasma furnace with circulating bath for electromagnetic pump.
Power generation: Thermal processing of biomasses and waste industrial and urban.

ConclusionsThe process of transforming waste into products
based on their financial, environmental and social impacts, is a key factor in the change of positive and negative externalities in this way contribute to the aluminum industry sustainability;
The literature is rich in studies of technological application for the RB, but little or nothing has turned into sustainable commercial activities;
A roadmap of activities to transform waste into products is very important in directing the efforts of the aluminum industry;

Conclusions
The targeting of efforts to transform the raw material into a RB to be sold in the market can not generate results;
The aluminum industry should think about adding value to the RB within their own generating plants RB, transforming it into a product, before being transported;
This paper attempts to serve as a gateway to an approach of applying RB broader, involving from the beginning trade and market variables.
