Solid-waste management is a major challenge in urban areas throughout the world. Solid waste management is associated with controlling the generation, storage, collection, transfer and transport, processing and disposal of solid wastes in a manner that is in accordance with the best principles of sustainability. It includes all administrative, financial, legal, planning and engineering function...

The University of Texas Medical Branch (UTMB) at Galveston is a large academic medical center with about 12,700 employees, 350 radioisotope research labs and 200 permitted radioactive materials users. Consequently, UTMB generates a fairly large amount of radioactive waste. The majority of this waste contains short-lived radionuclides, such as 32P, 33P, and 35S, which are held for decay and then...

This work reports the feasibility of applying emulsion pertraction technology (EPT) aiming at zinc recovery and waste minimization in the zinc electroplating processes that include Cr (III) passivation. The assessment consists of firstly the lifetime extension of the passivation baths by selective removal of the tramp ions zinc and iron, and secondly, the recovery of zinc for further reuse. Spe...

To eliminate hazardous hexavalent chromium from a brass wire-mill waste, hydrogen peroxide was examined In place of chromic acid for pickling, first in bench-scale tests and then in plant tests. Nthough the elimination of chromic acid requires more rigid control of the ~ wastewater treatment operation and increases the zinc content of the waste-treatment effluent, the economic benefit of substi...

Wastewater, spent solvent, spent process solutions, and sludge are the major waste streams generated in large volumes daily in electroplating plants. These waste streams can be significantly minimized through process modification and operational improvement. In this endeavor, extensive knowledge covering various disciplines is required, which makes problem-solving extremely difficult. Moreover,...
