In the first step, each company's Waste Productivity is calculated for 2012. Waste Productivity is defined as Revenue ($US) / [Total waste generated (metric tonnes) _ waste recycled/reused (metric tonnes)]. Each company_s Waste Productivity is then percent-ranked against that of all Industry Group peers in the CKC research universe and multiplied by 0.75. In the second step, the change in each company_s Waste Productivity from 2010-2012 is calculated and percent-ranked against that of all same-industry group peers within the CKC research universe. If the company_s percent-ranked 2012 Waste Productivity is top quartile, their percent-ranked change in Waste Productivity for 2010-2012 is multiplied by 1 and then by 0.25. If the company_s percent-ranked 2012 Waste Productivity is second quartile, their percent-ranked change in Waste Productivity for 2010-2012 is multiplied by 0.75 and then by 0.25. If the company_s percent-ranked 2012 Waste Productivity is third quartile, their percent-ranked change in Waste Productivity for 2010-2012 is multiplied by 0.5 and then by 0.25. If the company_s percent-ranked 2012 Waste Productivity is bottom quartile, their percent-ranked change in Waste Productivity for 2010-2012 is multiplied by 0.25 and then by 0.25. In the third step, the values from the first and second steps are totaled.
