Value Chain Waste Reduction Results
Delta's waste reduction starts with its own improvements and it
collaborates with the value chain to facilitate effective use of
waste and reduce the production of waste. Delta plants have
quantified value chain collaboration and overall effectiveness.
The total amount of waste generated was 79,865.7 tons, and the
total amount of all waste diverted was 79,466.3 tons, with a
diversion rate* of 99.5%.
*Waste diversion rate = reuse + reduction + recycling + waste
energy recovery + anaerobic digestion + biofuel + composting) /
total weight of waste generated; of which, the percentage of
waste energy recovery must be less than 10%.
Implementing Waste Management
Statistically, the total weight of waste at overall production
plants processed by qualified disposal institutions was
approximately 50,060.9 tons in 2021, of which, non-hazardous
waste accounted for 46,042.2 metric tons (92%), and hazardous
waste accounted for 4,018.7 metric tons (8%).
