Overview

• Recovering energy from waste is only appropriate
  for waste that cannot be prevented, reused or
  recycled with less greenhouse gas emitted.
• Energy recovery can be a sustainable option for
  waste that would otherwise go to landfill and
  create landfill methane emissions.

Conventional Technologies

• Direct combustion (incineration) of dry biomass
• The heat generated by the following wastes can be
  used directly to warm homes and buildings or to
  generate electricity using a steam turbine, or
  both, through combined heat and power systems
• direct combustion (incineration) of dry biomass
  waste such as wood waste, straw and poultry
  litter
• the biomass part of municipal waste
• some commercial and industrial wastes
• some construction and demolition wastes

Combustion of Waste-Derived Fuel

• The methane produced from landfill (landfill gas)
  is a waste-derived fuel. It can be used in the
  same way as for combustion plants or it can be
  injected into the national gas grid. Waste
  derived fuel is also referred to as Solid
  Recovered Fuel (SRF) or Refuse Derived Fuel (RDF).

5
Anaerobic Digestion

• Anaerobic digestion (AD) is a natural process in
  which micro-organisms break down the organic
  matter found in wet biomass waste (such as sewage
  sludge, animal manure and slurry and waste food)
  in the absence of oxygen, to produce biogas
  (mainly a mixture of around 60 methane and 40
  carbon dioxide) and digestate (a nitrogen rich
  fertiliser).

6
Advanced conversion technologies

• Gasification Gasification is a type of advanced
  conversion that produces a combustible gas that
  is a mixture of carbon monoxide, hydrogen, carbon
  dioxide and methane. This gas can be used
  directly to generate heat and electricity.
• Pyrolysis Pyrolysis is a type of advanced
  conversion that can be used to produce either a
  combustible gas, oil or solid char (sometimes
  known as biocoal). In the future, it will be
  possible to upgrade pyrolysis oil to produce
  petrol and diesel using oil refining techniques.

7
Environmental Controls

• All energy from waste plants must comply with
  regulations concerning environmental protection,
  animal by-products, duty of care, health and
  safety, waste handling and planning permission.
