Waste to Energy to Desalination

(w2e + dsal) :

New Yorkers produce, on average, 3 lbs trash per person per day for a hypothetical  50,000 people:
450,000 lbs MSW per day = 225 tons MSW per day = 135,000 kWh per day

Based on the desalination plant in the city of Santa Barbara:
49 gallons of water are desalinated by 1 kW/hour. The plant desalinates 23 million gallons per day using 135,616 kW/hours per day on 2.1 acres of land which supplies 150,000 people with 150 gallons a day.

Based on industry standards for waste to energy:
1 ton municipal solid waste = 600 kWh + 10% remaining fly ash
fly ash is 5% of original weight of material.
Bottom ash is 15% of original weight.

Based on the Marchwood Waste 2 Energy plant located in UK:
165,000 tons of municipal solid waste per year are processed on 2.5 acres.

One Brooklyn block is approximately equal to 3 acres 37 3-acre sites serving 150,000 people of w2e + Dsal for Queens and Brooklyn.

Doubling the size of these plants, we arrive at 18 plants which serve 300,000 people each.  if we add in NYC’s expected share of climate refugees, 600,000 people, we need 4 more.  The fly ash byproduct of the plants can be used in concrete and in asphalt.

For all 22 plants, 399 cubic yards of fly ash /day and 1197 cubic yards of bottom ash / day are generated.

The volume of new construction will require 20 million cubic yards of concrete for eventual buildout - more than utilizing the ash.
