Waste
In integrated production, we minimize waste by feeding byproducts back into the production loop. WACKER endeavors to avoid waste throughout the product’s entire life cycle. Groupwide, we record the volume of waste we generate according to the criteria “to be recycled” and “to be disposed of,” as well as “hazardous” and “non-hazardous.”
When it comes to solid waste, we prioritize prevention over recycling and recycling over disposal. We see it as one of our ongoing tasks to identify new ways of suitably recycling materials within and outside our sites.
It is very important to us that waste is recycled, treated and disposed of in an environmentally compatible and legally compliant manner. To this end, we monitor the disposal companies that we work with for recycling and disposal, performing regular audits.
Our German sites can use our internal Environmental Information System (EIS) to exchange information on these companies.
The amount of waste rose 6 percent groupwide. Possible reasons for this increase include higher quantities of construction waste at the Burghausen and Amsterdam sites and of residual organics from wastewater treatment at Burghausen and Charleston. Changes in production-related waste streams reflect trends in plant utilization.
