Material losses and the genera-tion of lower quality grades do have fi-nancial implications, though. Assumingthat it would be possible to producegrade B without producing lower qualitygrades and wastes, the profit would in-crease by 37% or 10,50€ per tonne offinal product (see best case scenario inTable 2). These figures are fictional as itis not possible to fully eliminate lowerquality grades and waste. Nevertheless,the results imply that paying premiumsfor high quality supplies, which lead toless unwanted products and wastes, isprofitable within a certain margin.
