Read the question carefully and give me right solution according to the question
Extracted text: In an industrial area, about 44 tonnes of energy intensive materials were recycled, 26 tonnes of organic wastes were composted to produce fertilizer, and the remaining waste (i.e. 25kg) was disposed to landfill. The substitution efficiencies of recycling and composting are 95%, and 70%, respectively. Determine the Zero Waste Index (ZWI) of this waste management system. (Calculated value should be a number of 2 decimal points and dont write any unit or % after the number)
