How do you compare the capacity of waste processing plants?
Short answer
Compare the same metric on the same basis. Design tonnes per day describe a plant’s rated capacity. Annual tonnes accepted or processed describe activity during a defined reporting period.
Confirm the denominator and boundary
Check whether tons are metric tonnes or U.S. short tons. Confirm whether the figure covers one line, the full facility, delivered waste, accepted waste, or material fed into a process.
Use realistic operating days
A 600 t/day line running 300 days at its design rate would process 180,000 metric tonnes in that scenario. That calculation is an estimate, and actual receipts depend on downtime, contracts, material quality, and the way the operator reports tonnage.
Ask for the records
Request the permit or engineering basis for capacity, and weighbridge or annual returns for actual throughput. Store dates and sources next to each figure.
