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.

爱德华王子岛省在夏洛特敦有一座垃圾发电厂，焚烧可燃物 固体废物并将产生的热量泵送到伊丽莎白女王医院和市中心。还剩下什么 焚烧后的剩余部分称为底灰。底灰被认为是无害残留物，并且 目前通过垃圾填埋方式处置。这些底灰残渣正在占用爱德华王子岛的宝贵空间 岛屿垃圾填埋场。荷兰学院的环境应用科学项目，与 FCMSA inc 合作。 将探索这种基本上惰性的材料的新途径，将其转用于其他目的。一个 建议将该底灰用作铺路石中的骨料，以替代砾石。这些 正在提议在加拿大各地的其他地点建立固体废物焚烧厂，因此寻找固体废物焚烧厂的创新用途 底灰变得越来越有价值。有趣的是，焚烧炉之间的底灰差异很大 加拿大取决于焚烧炉类型。它们会产生尚未得到充分研究的底灰 用作铺路石中的骨料，应研究如何处理这些残留物以使其 适合该用途。 FCMSA Inc. 正在探索建立收集、处理和处理业务的潜力。 为此目的使用灰烬，目前需要进行这项研究，以便将其商业化 铺路石。该项目将测试从夏洛特敦能源公司收集的底灰渗滤液 废物处理厂确定它是否是铺路石中砾石的可行替代品。
