The answer is 1960.

Answer 2

The total waste to energy that was generated in the United States is 211.11 million metric tons.

How to calculate the MSW generated?

From the table, the percentage of the MSW generated is 27%, therefore 73% will be unrecycled.

Therefore, since 27% of recycled MSW is 57 metric tons. Then 100% of MSW will be:

= (57 × 100)/27

= 211.11 million metric tons
