PRODUCING BIOGAS
FROM WASTE AND SLUDGE
Weltec Biopower is showing the importance it places on climate-neutral
At this year‘s IFAT, the
world‘s leading trade
fair for environmental
technologies,
which will be held
in Munich, Germany, from 4 to 8
May, biogas plant manufacturer
Weltec Biopower will again present
its anaerobic digestion plants for
industrial and municipal use.
In Hall A4, at Booth 508, the
internationally renowned biogas
specialists will provide information
on all topics concerning the use of
organic waste and sludge for the
production of energy.
The reference projects for the
digestion of waste and the
production of biomethane, which
is equivalent to natural gas, include
the Weltec plant of the French
potato chips manufacturer Altho,
whose chips brand Bret‘s accounts
for one third of the French market.
Every year, the plant in St. Gérand,
Brittany, produces about 1.75
million standard m³ of biomethane
from 22,000 t of production waste
in the form of potatoes and starch
as well as sludge from the internal
wastewater treatment plant.
This amount of the climate-neutral
energy source corresponds to the
gas consumption of a town of 5,000
inhabitants. Altho benefits greatly
from the biomethane production,
which enables it to use its leftovers
in a sustainable manner and cut
greenhouse emissions.
The annual savings amount to
approximately 3,900 t of CO2eq.
This corresponds to the emissions
that more than 2,000 persons would
cause with a flight from Munich
to New York.For the energy plant,
Weltec has implemented process
technology that is both innovative
and reliable: The mix of solid and
liquid substances is first preprocessed
and homogenised in
order to ensure efficient digestion
in the stainless-steel digester. The
entire process is fully automated
and controlled by a PLC unit.
“With the help of the membrane
processing, the biogas is then
transformed into biomethane.
Custom-tuned biogas technology is
a must,“ says Jens Albartus, director
of Weltec Biopower.
Usually, anaerobic digestion plants
will only encounter technical
problems if the process technology
does not meet the requirement
profile. For this reason, plant
operators and investors should opt
for a provider who has experience
with various substrates and climate
conditions.
In its projects, Weltec custom-tailors
its plants so as to ensure stable,
economic operation. In more than
300 planned and implemented
biogas projects in 25 countries, the
specialists have gained a wealth of
experience with diverse framework
conditions. Regardless of whether
sludge, abattoir waste or production
leftovers are used as raw material,
Weltec thus guarantees a high
energy yield. This is achieved with
the right blend of expertise, smart
processes and custom-tailored
supervision by biologists and
engineers. IFAT visitors will be able
to get further information on the
efficient conversion of organic
waste to high-energy biogas and
biomethane.
