Waste to Energy
Overview of Waste to Energy
When electricity or heat is generated from a waste source it is utilizing waste-to-energy (WtE) technology, thus reducing the amount of waste that would otherwise go into landfill, or reducing the amount of methane being released into the atmosphere from landfill and sewerage sites. It is necessary to consider the possibilities that WtE technologies present, not only from their energy generation potential, but also from their potential to reduce greenhouse gases.

A number of WtE technologies exist worldwide, with the most prevalent being landfill gas, wastewater gas, incineration and gasification. These will be examined in more detail in the files listed below.
It is important to remember that the most sustainable way to deal with waste is to eliminate it entirely. Reducing the amount of waste generated, reusing discarded items, and recycling and composting are fundamental principles in achieving zero waste. Municipalities should strive to achieve this goal.
