Tried and proven, base load renewable energy generation from waste resources
At Phoenix Energy, we only use tried and proven Energy from Waste (EfW) or Waste to Energy (WtE) technologies sourced from reputable technology providers. As a project develpoment company, our philosophy is to minimise technical and commercial risk for project stakeholders by selecting the most appropriate technology for the available waste resources and bringing together an experienced project team. As a minimum, the technologies we select must be proven at a commercial scale, with multiple reference sites processing similar waste feedstocks to those being considered for a local project, and they must be able to meet the most stringent international environmental regulatory standards.
Unlike solar and wind energy generation, Waste to Energy plants
are a unique source of continuous renewable energy generation.
By integrating the disposal of waste with the generation of energy, waste to energy plants provide a solution to two of society’s greatest challenges: waste disposal and energy supply. Thermal waste to energy plants have a minimal greenhouse gas footprint relative to current landfill and landfill to energy practices. With ~1000 grate type thermal waste to energy plants worldwide, there is no doubt that such aspirations are not only achievable but demonstrable in practice.
A large scale waste to energy plant serving a major city will enable the city to achieve two of its long-term strategic sustainability goals: Increasing the generation of baseload renewable energy and also reducing household waste to landfill by up to 100%. Furthermore, by providing an alternative to both landfills (and their associated methane emissions) and coal fired baseload power generation, a waste to energy plant will actually eliminate the generation of greenhouse gases by much more than the carbon dioxide emitted by the combustion of the non-renewable components in the waste feedstock.
Benefits of a modern waste to energy plant
- No need for upfront pretreatment or additional source separation of municipal solid waste, which reduces complexity and cost associated with waste collection and handling, and therefore does not require any change to current 2-3 bin collection systems (i.e. source separation of recyclables and green waste, where a separate collection services is available, from residual household waste).
- An independent North American study has shown that communities which have a waste to energy plant tend to recycle more than communities without a WTE plant.
- Long term waste supply agreements are required, which also give the community stable rates for waste collection and disposal, while also allowing the community to benefit through the local generation of baseload renewable electricity.
- Ferrous and non-ferrous metals can be recovered post-combustion from the solid bottom ash by-product and recycled, thereby further increasing recycle rates and reducing GHG emissions through avoidance of virgin materials production and associated energy consumption.
- Additional full time employment positions would be created for plant management, operation and maintenance. In more established markets in North America, Europe and Japan, companies are developing technologies to reuse the solid ash (or slag) by-product in construction products such as bricks and aggregate for roads, thus offering the potential for zero waste to landfill.
