In
1996 Veolia built a state-of-the-art Energy Recovery
Facility (ERF) in Tyseley, just to the east of Birmingham
City Centre, which takes 350,000 tonnes of Birmingham’s
rubbish each year and converts it into electricity.
This energy production is enough to power 41,000
local homes.
The new ERF plant was built to comply with strict
European emissions standards that came into force
in 1996. The facility was specifically designed
to treat waste that cannot be re-used, recycled
or composted and was built with a capacity much
lower than the total waste generated in the city.
This is to ensure that recycling initiatives are
not compromised.
The ERF has become a landmark building in Birmingham
with its bold architecture and an award-winning
lighting scheme that illuminates the plant to its
full advantage during the hours of darkness.
How the plant operates
The ERF operates 24 hours a day for 365 days a
year (except for planned shutdowns for maintenance)
and operates well within the UK and EU standards
for emissions to atmosphere. It is a two-stream
plant with each boiler designed to process 23.5
tonnes of rubbish per hour. It has a turbo-generator
which exports 25MW to the National Grid, after providing
for on-site needs. Veolia ES Birmingham has a Non-Fossil
Fuel Obligation (NFFO) contract, under a government
scheme to support renewable energy. A large proportion
of this financial benefit passes to the City Council.
The ERF also recovers several thousand tonnes a
year of ferrous metals for recycling from the process.
Incinerator Bottom Ash (IBA) is the non-hazardous
ash material that is produced from the incineration
process. This material is reprocessed by extracting
further ferrous and non-ferrous metals and by crushing,
tromelling and screening to produce a graded, quality
material that is useable as substitute aggregate
in such applications as road building. 95% of the
IBA produced from Tyseley is recycled in this way.
Air Pollution Control (APC) Residues or Fly Ash
is the only hazardous waste that is produced from
the whole process and is the equivalent of just
2% of the inputs. This waste, which is strongly
alkaline, is transported in sealed powder-tankers
and used to neutralise acidic wastes to produce
a neutral filter-cake material.
