A waste-to-energy (WTE) plant is constructed in TWO (2) PHASES:
1. PHASE 1is elimination of the waste by gasification (incineration). This Phase 1 represents 10% to 15% of the full Waste-to-Energy plant cost. With normal tipping fees it is quickly paid for and profitable. Construction completion is very rapid.
2. PHASE 2 is the energy recovery or electricity generation, and it can be constructed at any time following Phase 1. This power generation is 85 to 90% of the cost of the full WTE plant. This Phase 2 is more easily justified after Phase 1 is operational, and when the value of recovered energy is established.
If garbage cleanup and elimination is critical and the most important issue for a city, a two phased construction may be financially and practically advantageous. The Phase 2 energy recovery can be added any time later, when it is more easily afforded and justified.
In addition the initial Phase 1 portion can be fabricated locally, saving construction and shipping costs and providing local employment.
Clean up following Natural Disasters such as hurricanes, floods, or oil spills may also benefit from a rapid and affordable Phase 1 installation.
