Examining the potential uses of bottom ash from an energy from waste plant on Prince Edward Island

爱德华王子岛有一个位于夏洛特敦的垃圾发电厂， 固体废物和泵产生的热量到伊丽莎白女王医院和市中心的核心。还剩下什么 焚烧后的剩余物称为底灰。底灰被认为是一种无害的残留物， 目前通过填埋处理。这些底灰残渣正在占用爱德华王子市宝贵的空间 岛屿垃圾填埋场。荷兰学院的环境应用科学计划，与FCMSA公司合作。 将探索新的途径，将这些基本上是惰性的材料转移到其他用途。一 这种底灰的建议用途是作为铺路石的骨料，代替砾石。这些 固体废物焚烧厂被提议在加拿大的其他地点，所以寻找创新的用途， 底灰越来越有价值。有趣的是，不同焚烧炉的底灰差异很大， 加拿大，取决于焚化炉类型。它们可以产生一种底灰，这种底灰还没有得到很好的研究， 作为铺路石的骨料使用，应研究如何处理这种残留物，使其 适合使用。FCMSA Inc.正在探索建立一个收集、处理和 为此目的使用灰，目前需要这项研究，以便进行商业化， 铺路石该项目将测试从夏洛特敦能源公司收集的底灰的渗滤液， 废物处理厂，以确定它是否是一个可行的替代砾石铺路石。

Prince Edward Island has an energy from waste plant located in Charlottetown, which incinerates burnable solid waste and pumps the resulting heat to the Queen Elizabeth Hospital and the downtown core. What is left over after incineration is known as bottom ash. Bottom ash is considered a non-hazardous residue and is disposed of currently by landfilling. This bottom ash residue is using up valuable space in Prince Edward Island landfills. Holland College's Environmental Applied Science Program, in collaboration with FCMSA inc. is going to explore new avenues for this material that is largely inert, to be diverted to other purposes. A proposed use for this bottom ash would be as an aggregate in paver stones as a replacement to gravel. These solid waste incineration plants are being proposed for other sites across Canada, so finding innovative uses of bottom ash is becoming of more value. Interestingly, the bottom ash differs greatly between incinerators in Canada depending on the incinerator type. They can produce a bottom ash that has not been well studied for use as an aggregate in paver stones, and it should be studied how such residue should be treated to make it suitable for that use. FCMSA Inc. is exploring the potential to build a business for the collection, treatment and use of ash for this purpose, and currently require this research in order to proceed to commercialization of paver stones. This project will test the leachate of bottom ash collected from the Charlottetown Energy from Waste plant to determine if it is a feasible replacement to gravel in paver stones.
