The combustion strategies produce the greatest energy savings and the largest quantities of
available electricity. Recovering gas from landfills and burning it to produce heat or electricity is
the next most energy-efficient strategy. Recycling achieves some energy savings, but the
quantity is smaller. All mass burning strategies and RDF preparation and direct combustion
strategies include recycling to some degree. The energy savings associated with the recycling
are included in the estimates in Figure 2.1.* Composting is the only technology that produces no
* Recycling in Strategy 2, Mass Burn, consists of recovering about 3% of the weight of the MSW as ferrous metal
