The Manchester Waste-toEnergy plants
(CHP) plant for the Greater
Manchester Region, which is
considered to be the largest of the six
U.K. waste authorities.
(Summary by Athanasios Bourtsalas,
EEC)
The contract was signed between
Keppel Seghers and Ineos Runcorn
TPS Ltd (a joint venture between
Ineos Chlor, Viridor Waste
Management Ltd. and John Laing
PLC), who will be responsible for the
procurement, operation and
maintenance of the WTE plant. The
contract is part of a Private Finance
Initiative (P.F.I.) waste management
project by the Greater Manchester
Waste Disposal Authority (GMWDA).
As the first of its kind in the UK on this
scale, the project can divert more than
75% of Greater Manchester’s waste
away from landfills by focusing on
sorting out waste for recyclable
materials and refuse-derived fuel
(RDF).
Approximately 275,000 tonnes of
waste will be delivered by GMWDA,
and Viridor will deliver the remaining.
The plant has a capacity to treat up to
420,000 tonnes per year of Solid
Recovered Fuel (SRF) derived from
household waste and it will be able to
supply at full capacity 270,000 MWh
of electricity and 500,000 tons of
steam into the internal network of the
Ineos Runcorn site.

Manchester Waste-to-Energy plant
The Greater Manchester Waste
Disposal Authority (GMWDA) handles
5% of the United Kingdoms’ municipal
waste (approximately 1.3 million
tonnes of MSW).
The environmental technology
division of Keppel Integrated
Engineering (K.I.E.), Keppel Seghers,
secured on May 2009, £ 233 million
EPC (Engineering, Procurement and
Construction) contract ($ 377.7
million, as of currency May 13th, 2011)
in order to provide the appropriate
know-how and built a Waste-toEnergy combined heat and power
The WTE plant started operations on
August 26, 2010. The phase I of the
plant employs the Keppel Seghers’
water-cooled grate and enhanced heat
recovery technologies as well as the
company’s double dry flue gas
cleaning system.

Subsequently, Keppel Seghers was
also awarded on October 11th, 2010,
the Engineering, Procurement and
Construction (EPC) contract for the
Phase 2 (Runcorn II) of the project by
Viridor Waste Management ( $341
million ). Runcorn II will be integrated
with Phase 1 (Runcorn I).
With the capacity to treat an
additional 375,000 tonnes of SRF
derived from household waste, the
combined Phase 1 and Phase 2 of the
plant will have a total capacity to treat
750,000 tonnes of waste per year and
generate, at full capacity, 70 MW of
electricity and 51 MW of heat.

plant
Runcorn II will also use Keppel
Seghers' Water-Cooled Grates, the
horizontal boiler design integrated
with the KS Prism technology for
enhanced heat recovery and a double
dry flue gas cleaning system.
When both phases are completed
(expected by 2014/2015), the plant
will be one of the largest WtE facilities
in Europe.
There is already a WTE plant, located
in Lancashire (Bolton, Figure 2), that
is operated by Greater Manchester
Waste Ltd. The configuration of this
plant is 1X10 MW, and started its
operation in 2000. The provider of the
incineration/boiler system is the
Babcock&Wilcox Volund (Danish
company), and the turbine generator
is by/G Supplier is by Ansaldo Energia
of Italy. Moreover, the plant was
converted from an old mass-burn
incinerator to a WTE plant in
2000.The capacity of the plant is
175,000 tonnes of MSW per year, with
electricity output of 96 GWh per year.
