Note 21: Raw materials efficiency


Effective waste management helps to increase raw material efficiency in our manufacturing operations, while reducing both costs and our environmental footprint. Our focus is on reducing total waste and eliminating hazardous waste to landfill. The exception is asbestos waste – mainly from demolishing old equipment and buildings – where the preferred current safe disposal route is properly designed landfill facilities.

A program for waste prevention through alternative outlets for obsolete paint is in place. These are sent to processors and distributors and can prevent waste streams up to 10 percent of the company’s total.

  • Total waste per ton of production generated and leaving our sites is down 11 percent to 11.6 kg/ton (2010: 13.1 kg ton). The total waste volume came down to 217 kilotons (2010: 258 kilotons), a decrease of 16 percent. This was partly due to the divestment of the National Starch business in 2010 and the site closures of Grand Quevilly in 2010 and Emmerich in 2011, and partly to many improvements at our manufacturing sites as part of the operational eco-efficiency program
  • Hazardous waste to landfill per ton of production is down 33 percent to 0.16 kg/ton (2010: 0.24kg/ton) and the total figure is down 36 percent to 3.0 kilotons (2010: 4.7 kilotons). This is mainly due to the divestment of the calcium carbide business in 2011
