Vital Materials Co.,Ltd. is an ISO14001 certified producer and adheres to all local and international environmental regulations. We apply the best known available technology and our own proprietary methods in handling our waste. All workshops are connected to scrubbers for gas emission control. Spent process water is treated using a combination of processes which include precipitation, neutralization, filtration, clarification, distillation, crystallization, ion exchange, and reverse osmosis. By applying these series of processes, we have the capability to convert our spent process water to clean process water. We strive to achieve our goal of recycling 95% of our treated water. Most of our solid by-products are either treated on-site or used by other industries for the recovery of metal values. Those that cannot be recycled are handled by qualified and licensed companies for proper treatment and final disposal.
