Abstract: This study aimed at helping an Acrylonitrile Butadiene Styrene (ABS) resin company to improve its environmental performance and comply with the sustainable development required by Chinese government and corporation itself. The processes of ABS resin production amounts of waste gas, water and solid waste. In the most cases in China, the environmental issues from this industry have been focused on the end of pipe treatments during the last two decades. Recently, with the increasing emphasis on environmental protection from the society and the needs of enterprise self-development, the cleaner production programs have been introduced in some ABS resin companies. In this study, we made a close examination of ABS resin company in Ninigbo, an important light industry base in Eastern China. Base on understanding of ABS resin processes and collecting data of energy consumption, resource consumption and discharged pollutants, cleaner production opportunities for three main steps of ABS processes were analyzed. Cleaner production options were proposed for emulsion grafting process step. The feasibility studies for 4 higher-cost options were delineated in this study. After implementing 30 different independent cleaner production options, the company improved its environmental performance obviously. Material consumption and energy consumption per unit product decreased 10.05 and 15.5 kg tce, respectively. Cleaner production brings remarkable economic and environmental benefits for the company by means of energy saving and pollution reducing.
