Elmo
starts new treatment plant
Reduces nitrogen emissions by 80%
County
governor Göte Bernhardsson inaugurated Elmo Leather’s new treatment plant at
Svenljunga, Sweden, on June 1. The process is based on a completely new
technology for biological treatment that reduces nitrogen emissions in
wastewater by 80 % compared with 30 % for the previous plant.
This
is the first time that this new and innovative treatment technology is being
used for wastewater in the tanning industry. The total cost of the project is
around SEK 50 million (EUR 5.45 million), of which around SEK 8.25 million (EUR
900,000) was contributed by the EU’s LIFE environmental fund.
Dynamic environmental policy
According
to Elmo Leather’s CEO, Nalle Johansson, the company has been pursuing dynamic
environmental policies for many years. Elmo’s management system for
environmental work has independent certification and the company has managed to
reduce the environmental impact of its activities over the years in terms of
waste and emissions to air and water.
“By
changing processes and chemicals and using traditional techniques we had come as
far as it was possible in tackling nitrogen pollution in our wastewater. To make
further progress and achieve further improvements we needed to introduce a
completely new treatment process for the tanning industry,” explains Nalle
Johansson.
Micro-organisms eat pollutants
The
new innovative technology used by Elmo is based on a process called
nitrification/denitrification, which is an advanced form of biological
treatment. The technology is used by municipal treatment plants, but has never
before been used in the tanning industry because it was considered that the
properties in tanning industry wastewater were technically unsuitable.
The
new technique means that pollutants are broken down by micro-organisms in the
water in a series of processes in which the wastewater is treated in separated,
but linked, tanks.
Oxygen
is added to the wastewater initially, which increases the number of
micro-organisms. In the next stage, the oxygen is cut off and the
micro-organisms are forced to eat the pollutants in order to survive.
The
outcome is that nitrogen emissions are reduced by 80% as most of the
nitrogen-containing pollutants are converted into nitrogen gas, which is the
same gas that dominates the atmosphere. Traditional wastewater treatment in the
tanning industry cuts nitrogen emissions by around 30%.
Staying in Svenljunga
At
the inauguration of the new plant, Nalle Johansson admitted that he shared the
concern of people who feared that an increasing amount of industrial production
and thereby jobs were being moved out of Sweden. He noted that Elmo Leather had done exactly the opposite in
recent years.
“We
have concentrated our production in Svenljunga and moved production back to
Sweden from Denmark and the US,” he said.
According
to Johansson, after building the new treatment plant, Elmo will base the
predominant part of its future production of leather at Svenljunga.
“That
does not mean that we will exclude the possibility of locating certain parts of
production, such as die-cutting and sewing the finished leather, closer to our
customers or in places where it is cheaper to perform them. Our core activity,
however, the actual manufacturing of leather, will remain in Svenljunga,” says
Elmo’s CEO.
EU
support for innovative technology
The
overall cost of the new treatment plant is around SEK 50 million (EUR 5.45
million), of which Elmo contributed around SEK 42 million (EUR 4.5 million). The
company also received a subsidy of around SEK 8.25 million (EUR 900,000) from
the EU’s LIFE environmental fund.
LIFE
provides financing for projects that support environmental protection and nature
conservation throughout the EU. The aim is to advance and develop EU
environmental policies by supporting reference projects that showcase innovative
technology or methods. LIFE projects shall act as good examples of how policies
can be converted into action. The supervisory authority for LIFE in Sweden is
the National Environmental Protection Agency.
