The objective of the present waste minimization study for printed circuit (PC) board manufacture is to evaluate solid/liquid separation technologies, engineering data, waste recycling processes, and cost economics to assess the feasibility of achieving significant reduction in the usage of water, the generation of wastewater, and hazardous wastes. Two examples, for small and large manufacturers, demonstrate that an integrated waste minimization scheme can minimize waste by in-process recycling, resource recovery, process modification, and automation. Economic analyses of these two examples show that the integration waste minimization scheme is more profitable than that of the conventional sludge or the zero sludge schemes.
