Showa Denko K.K. (SDK) has announced that the company has made a decision to reorganize its industrial waste recycling program, with the incorporation of a companywide program and independent recycle programs supervised by every plant
The companywide program has the objective of advancing the reduction of industrial waste that was produced during the production processes.
Industrial waste reduction is being done in order to minimize the burden in the global environment and improve society’s view on recycling. Reuse of waste plastics and oil as fuels, and reuse of waste alkalis and acids are included in the company’s efforts in minimizing the industrial waste and increasing the resource consumption effectively. These efforts have enabled nine plants to achieve zero emission as of May 2012. The effectiveness of each plant’s independent operation to recycle or process industrial waste has reached its limits and overall, 2.2% of the annual industrial waste is landfilled.
In order to organize the initial phase of the companywide recycle campaign, the company will recycle the organic discharges that originated from domestic plants, with the help of the plastic chemical recycle facility in the company’s Kawasaki Plant. These organic discharges can be reused as raw materials in order to generate liquefied carbon dioxide and ammonia.
SDK will examine the state of industrial waste and facilities of every plant for waste treatment, and advance a companywide recycling program of additional waste and other organic discharges. This effort is targeted at achieving zero emission with reduction in landfill ratio to 1% or less of industrial waste and to minimize the outsourcing expenses to 500 million yen for industrial waste treatment.
