A multi-year research developed since 2003 between the University of Trento, Italy, and the Politehnica University of Bucharest, Romania, allowed defining a few design criteria useful for the optimization of the energy balance and for the minimization of the environmental impact. The design parameters for the biological process are related to the varying food waste content of the input. Values ...

Wastewater management in two companies representing the pharmaceutical industry was investigated and implemented. The results showed that the integration of the pollution prevention approach followed by an equalization tank reduced the organic load up to 70%, while further chemical treatment using either alum or ferric chloride aided with lime produced a quality of effluent suitable for restric...

This report examines opportunities for the application of economic incentive instruments for the management and reduction of hazardous wastes. The analysis concludes that as long as firms comply with existing regulations and bear potential tort liability, no additional incentives appear to be warranted. There may be significant residual external damages, however, if full compliance cannot be en...

Samples of the waste rock obtained from Marofengin South Africa ground 60, 70 and 80% passing 75µm were leached with cyanide in bottle roll tests. The results obtained showed that the percentage gold dissolution depends more on the ore size consists than on the cyanide concentration with the highest average dissolution rates of 88.75, 94.34 and 95.90% found at 600, 500 and 500 ppm, for 60, ...
