airport waste, such as food and
packaging, into energy.
The £ 3.8M (US $4.7M) waste-to-energy plant turns Category
1 waste and other organic waste
into energy to heat Gatwick’s
waste management site and
power the site’s water recovery
system. When in operation, the
plant could save the facility up to
£ 1,000 (US $1250) in energy and
waste management costs per day.
Category 1 waste is defned
as food waste or anything
mixed with it, such as packaging, cups and meal trays from
international transport vehicles. Through the plant, waste
is turned into a dry-powdered organic material, used as fuel to
heat the site and dry the waste for the next day.
DHL Supply Chain already manages inbound deliveries at Gatwick Airport through its logistics and consolidation facility on
behalf of the airport’s 150 partners and retailers. The development of the new waste management plant is also in sync with
Deutsche Post DHL Group’s recently announced commitment to
reduce all logistics-related emissions to net zero by the year 2050.
Waste-Heat-to-Energy in Turkey, New York, and California
Turboden, a Mitsubishi Heavy Industries (MHI) company said its 65
HRS ORC unit, which converts waste heat to energy will be installed
at the Düzcecam Glass Plant in Düzce, Turkey. The unit, designed
for 6. 2 MW nominal capacity, will convert the off-gas waste heat
from the two foat glass production lines into electric power. It is
expected to be online in early 2018.
The heat recovery system confguration includes a set of thermal
oil boilers (one for each line) with a heat carrier circuit to convey
the heat from the exhaust gas to the ORC unit. The two waste heat
boilers, in parallel with the existing quenching tower system, will
produce thermal oil up to 315°C. The hot thermal oil (heat carrier)
transfers thermal power to the ORC turbogenerator working fuid,
which then expands in the turbine to convert incoming thermal
energy into electric power by means of an electric generator.
In related news, PwrCor
said that it has initiated a program with ConEd to develop a
pilot project based on its PwrCor engine, which employs
waste-heat-to-power technology. The engine captures
waste steam condensate and
converts it to electricity before
it is disposed of in the municipal sewer system.
By capturing the steam condensate, PwrCor says that its
technology delivers electric
power to the building and also
cools the hot water, eliminating the need to purchase water
to temper the over-hot condensate before it can be disposed
of in the sewer system.
The company is also
exploring how its technology
could be used in conjunction
with geothermal power.
