High Efficient Technology
A High Efficient Waste-to-Energy (WtE) plant is a crucial part of a sustainable waste management chain. It provides a safe sink solution for all waste that otherwise would end up in landfills. Landfills (even sanitary landfills) are a long-term threat to the society, due to greenhouse gas production and leaching.
WtE is not a replacement for recycle and reuse initiatives, and not in competition with that, but rather an essential starting point for sustainable waste management. Its function lies at the end of the life cycles of products where it treats the residual waste which cannot be recycled, but has an energetic value for replacing fossil fuel.
The technology from AWECT, which was developed by AEB Amsterdam, is the most efficient in the world. It can generate 900 KWhof electricity from 1 ton of waste(@ LHV of 10MJ/kg). The emission levels can be as low as 20-40% of EU directive emission levels, making it very clean and partly renewable energy.
High efficiency Waste Incineration built in Amsterdam has been in full scale commercial operation since 2008. It is the largest renewable energy production plant in Amsterdam. The cumulative throughput of AEB HE-plant has been over 5.5 million tons of waste since commissioning. The availability of the plant is proven to be over 92%; as for the boiler/steam part, it is even over 95% .
An incineration plant burns waste at high temperatures to generate heat. The heat makes steam which drives turbines to generate electricity. In this way, a WtE plant turns municipal and industrial solid waste into electricity and/or heat. The mass reduction of this process is more than 99%. The leftover materials, such as bottom ashes, can be reused or disposed in a safe way.
The technology should be evaluated on availability, efficiency and greenhouse gas emissions. The more energy you can produce from residual waste, the more cost-efficient the solution will be for all stakeholders, and the more greenhouse gas emissions will be reduced. The technology provides baseload power to the electricity grid that is crucial in the renewable energy mix with wind and solar, replacing coal fired power plants.
