Diagram states --> total waste = 601,150; special industrial = <1%; non-hazardous inustrial = 8%; green (also non-hazardous) = 91%

Total non-hazardous waste = non-hazardous waste industrial + green

Non-hardous waste = 601,150 x 8% = 48,092

Green = 601,150 x 91% = 547,047

Total non-hazardous waste = 48,092 + 547,047 = 595,139 tonnes

conversion to metric tonnes = 539,901
