[CEST2019_00909] Challenging the belief that landfill has higher net CO2 emissions than waste-to-energy incineration or composting
by Hutton B., Norrish M., Horan E.

Landfill is generally believed to have higher greenhouse gas emissions than composting or waste-to-energy. The EU Landfill Directive requires nations to progressively divert biodegradable waste away from landfill. Waste disposal in landfill is at the bottom of its Waste Hierarchy. Many nations also ban landfilling of plastic. These policies may inadvertently increase global warming by increasing incineration. In Europe, Waste-to-Energy (WTE) incineration emits 72,000,000 tonnes of fossil CO2 a year, increasing yearly. Landfill methane is now generally captured.

The article draws attention to the problem of the presence of selected metals in waste electrical, electronic equipment (WEEE). These metals belong to the group of critical metals (germanium), strategic metals (tellurium) and highly toxic elements (thallium). Due to low content of these metals in e-waste, they are usually ignored during e-waste analysis, therefore they belong to the least-known metals in the literature regarding waste recycling. Their presence in WEEE can cause them to be concentrated in the environment during improper e-waste processing.

Bottom ash (BA) is the dominant residue from municipal solid waste or refuse-derived fuel incineration. Disposal costs chiefly depend on the leachability of trace metals and salts. The mobility of these constituents is classically minimized by ageing for several months. Ageing involves the oxidation of metals, dissolution and precipitation reactions, and most importantly, car-bonation of BA induced by the uptake of carbon dioxide. Enhanced exposure to carbon dioxide sources has been referred to as accelerated carbonation.
