Prevent, Recycle, Reuse before Waste to Energy (WtE)?

Quite simply – after separating the recyclable components in the waste stream, using new technology to extract the calorific value (energy) inherent in our waste.
  • The first step in managing our waste is to reduce it through better packaging and more recyclable waste – whether in the home (compost, for example), through repurposing items (e.g. old clothes), or separating out the recyclable components and disposing of these separately.
  • Waste streams that would have been destined for landfill sites or incineration plants are sent to the new waste-to-energy site, any remaining recyclable material is removed and the rest is processed, producing power, fuel, clean water and other by-products.

What is Waste-to-Energy (WtE)?

Waste-to-energy technologies consist of various methods for extracting energy from waste materials. These methods include thermochemical and biological methods.
The Figure below provides an illustration of the various energy pathways for WTE. Of these pathways, most are maturing from early developmental stages. Currently the WTE technologies that are commercially proven world-wide using MSW feedstock are combustion, anaerobic digestion and pyrolysis. All other processes hold high potential for utilizing MSW feedstock, but must overcome various technical, institutional, economic, environmental, and/or procedural challenges to become commercially viable.
The primary challenge facing these technologies is the heterogeneous nature of MSW, which creates a widely varying chemical constituency of the energy products generated from these processes. This variance affects the ability to efficiently extract energy. Solutions are actively being pursued from two angles.
