Question

One ton of municipal refuse has a calorific value between 6 and 12 MJ/ kg. Collecting and disposing of it require about 5000 MJ/ton. Calculate the number of toe corresponding to 1 ton of refuse. In France, a city of 100,000 inhabitants generates about 35,000 tons of refuse per year. Calculate the amount of energy potentially available and the quantity of oil equivalent.

Accepted Answer

1 toe = 42 GJ. Therefore 1 ton of refuse is equal to 0.14 – 0.3 toe. 35,000 tons of municipal waste corresponds to values between 210,000 GJ = 58 GWh (5 ktoe) and 420,000 GJ = 117 GWh (10 ktoe). Per inhabitant, the potential energy contained in refuse is on the order of 50–100 koe.

We have the following data: 1 toe = 42 GJ = 11.6 MWh. The combustion of 1 toe gives 3.7 tons of CO2 . One ton of dry wood equals 5.22 MWh. Since there is space between the pieces of wood, the volume corresponding to 1 ton is about 2 m³. Assume an oil-fired boiler has an efficiency of 80% and a ...
