Coal power plants have the highest emissions of carbon
The old part of the plant is less efficient
The new part doesn’t haven’t to process the trash before burning it.
- the difference in technology allows them to be more efficient
- The new plant can hand more waste and different types
300-400 trucks come in with trash and 20-25 trucks leave with ash per day
- 90% decrease
Landfill will only take things unrecyclable or noncombustible

- crane has to move trash back to leave space on the tipping floor
- Put trash on the hopper to keep fuel
- Can hold 5,000 tons, 2 total so 10,000 ponds total at the plant

One of the only plants that takes trash and sewer sludge and deal with them separately
If it went to the landfill it would be 80 worse releasing greenhouse gases

When the economy goes down, trash goes down

Each town had their own dump site in the 1940s so their are about 60 abandoned dump sites

They only use non-drinking water for their plant
- good because of the drinking water shortageEn savoir plus
