[[Fly Ash]] and [[Air Pollution Control]] (APC) residues are often combined. APC residues contain ash, carbon and lime in varying quantities and is considered a [[Hazardous Waste]] to be disposed of in a [[Hazardous Landfill]], or sometimes to be further processed through washing or stabilisation in order to make it a non-hazardous waste and allow it to be disposed of in a [[Non-hazardous Landfill]]<ref name='ref3' />. | [[Fly Ash]] and [[Air Pollution Control]] (APC) residues are often combined.

The [[Syngas]] produced from [[Advanced Conversion Technologies]] is comprised of hydrogen, carbon monoxide and methane. This is often combusted in order to generate electricity or in [[Waste to chemicals]] processes it can be turned into a fuel<ref name='ref3' />. | The [[Syngas]] produced from [[Advanced Conversion Technology | Advanced Conversion Technologies]] is comprised of hydrogen, carbon monoxide and methane.

Energy from Waste processes play a vital role in diverting waste from landfill and in generating energy. EfW is the preferred technique for managing waste over [[Landfill]] providing there is sufficient renewable content in the feedstock and the EfW plant is operating at an energy-efficient state (guide to the debate)<ref name='ref2' />. Recycling is higher up in the [[Waste Hierarchy]] and therefore EfW processes should not in principle take feedstocks that include recyclable materials. However, often a synergy exists between EfW and [[Recycling]] where the two waste management techniques can complement each other and work together to reduce waste sent to [[Landfill]]<ref name='ref2' />. | Energy from Waste processes play a vital role in diverting waste from landfill and in generating energy.
