The old process is 200 tons more than the environmental protection limit, and the new process is less 100 tons.

So the old process is 200+ 100=300 tons more than the new process.

New is better than old =2 to 5.

So each serving is 300 divided by (5-2) =100t.

So the new process 2 times 100=200 tons, and the old process 5 times 100=500 tons.
