Author(s): Stephen R. Cattle, Carl Robinson, Mark WhatmuffAbstractThe re-use of waste materials by application to land is an increasingly common practice around the world, but where municipal solid waste materials are applied, it is almost inevitable that physical contaminants such as glass and plastic will be added to the soil. In many jurisdictions, there are prescribed limits for the amounts...

Author(s): Suthatta Dontriros, Suched Likitlersuang, Dao JanjaroenAbstractA general approach to managing municipal solid waste is by incineration. Unfortunately, large amounts of municipal-solid-waste-incineration fly ash (MSWI FA) is produced in the process, with their heavy metals content posing further problems to the environment. One fundamental treatment of MSWI FA heavy metals is called...
