Solid Residues& Hazardous Residues

The recent publication of the Government Policy for Solid Waste , came to meet a number of shortcomings and challenges in the management of solid waste. Even before the publication, already in place, became even more important, the regulatory standards for industrial waste characterization and for hospitals as well.

The NBR 10004, 10005, 10006, dealing respectively with the evaluation of the crude residue, called "Gross weight", the evaluation of the leachate and the solubilized gross mass. Thus, the three standards propose criteria for analysis and classification of industrial waste, which guide its final destination.

The NBR 10007 establishes criteria for sampling of waste, not exhaustive, but objective.

Whereas the waste generator is jointly responsible for the same irrespective of disposal, nor the lifetime of the residue becomes essential to proper and adequate description of the residue. This description will guide the definition of any additional parameters in the characterization stage, and final destination.

The NBR 12.808 establishes general criteria for wastes of health services, and refers to NBR 10.004 regarding the analytical part.

At the state government of Parana CEMA published Resolution 076/2009 laying down specific criteria for co-processing of waste in cement kilns, seeking replacement of raw material or energy recovery.

In São Paulo, Cetesb in its publication "Executive Decision No 152/2007" also adopted procedures for managing foundry sands. All this accredited by ISO / IEC 17025.
