Abstract

Mariwasa Siam Ceramics, Inc.(MSCI) is a manufacturer, exporter and distributor of ceramics,sanitary ware, and building material products for sale in the Philippines and in foreign markets.MSCI holds the distinction of being the first to manufacture both wall and floor in a vast range of colors and sizes in the Philippines since 1966. To comply with the Philippine Environmental Policy, which is defined as the general policies in the pursuit of a better quality of life for the present and future generations and mandates the undertaking in the environmental impact assessments for all projects, which may significantly affect the environment, they established objectives that will support the policy. The general objective of the study is to show how MSCI makes use of their effluent and treated sludge that comes from the Glazing Line in compliance with the sustainable development policy in the country. The study began on April 19, 2010 until May 23, 2010. The study took place at Mariwasa Siam Ceramics, Inc. located at San Antonio, Sto. Tomas, Batangas.To be able to illustrate how the recycling is practiced in MSCI, it is importance to start with how the wastewater is generated. The phases in the operational flow of the Wastewater Treatment Plant (WWTP) were observed. The study shows the effluent quality and tests the bending strength of the tiles produced with recycled treated sludge. It also discusses the cost saved in recycling sludge compared to cost of letting a private firm carry out sludge disposal. With regard to the quality of the effluent coming from the Glazing Line, laboratory tests conducted by Aeronics Incorporated Environmental Laboratory Division showed that MSCI passed the standards set by the Laguna Lake Development Authority (LLDA). On the other hand, the percentage of the recycled treated sludge added to the tiles must not exceed 3% of the total composition of tiles so that the desired properties may not be compromised. the reuse of effluent and treated sludge can be better optimized if further studies and experiments will be conducted to explore on other potential or possible uses. In the recycling practice of MSCI, they actually help in conserving and enhancing to deal with the increasing wastes with depleting available disposal sites.
