Interseroh: Where climate protection is a matter of course

INTERSEROH Dienstleistungs GmbH in Cologne is one of the leading environmental service providers. Under the guiding principle of “zero waste solutions”, the company gives customers advice on material and logistics cycles such as deploying re-usage or recycling systems for recyclable waste materials. In particular, a demonstrable and extensive impact on climate protection is linked to efficiently recycling various raw materials. Not only is climate protection an important part of Interseroh’s business activity, however; the company also specifically tackles its own impact in terms of climate change mitigation and has developed a range of different efficiency measures to address this.

Interseroh plans to halve its site emissions by 2025 compared to 2015, for example. All its sites, totalling 31 in eight countries, are committed to constantly improving their environmental performance – including reducing their consumption of materials and energy and lowering emissions. They have already been able to reduce CO2 emissions by around 1,200 tonnes by using efficient pumps, regularly eliminating compressed air leakages and changing over to LED lighting. In 2017, following the measures implemented in 2016 and other improvements, overall energy consumption at company sites was reduced by 4,474 million kilowatt-hours, which equates to a reduction of 6.4 per cent compared to the previous year. In addition, in 2017, total emissions for the sites were reduced by a further 1,990 tonnes of CO2 equivalents – equating to a 6.6 reduction compared to the previous year.

Climate protection objective:

  • Reducing emissions at company sites by 50 per cent by 2025, compared to the reference year 2015

Saving resources, tackling climate change – INTERSEROH hopes to makes its contribution, on the one hand through its products and services and on the other by reducing its own ecological footprint. To this end, the company calculated its corporate carbon footprint in 2017 and adopted a climate strategy.

Sustainability for the future

In future, Interseroh plans to further increase the level of digitalisation and thus make processes more efficient, while at the same time reducing the use of paper. In addition, there are plans to use the waste heat from the computer centre for heating purposes and to reduce the quantity of cleaning products used on company premises. The company is also looking at purchasing hybrid and electric vehicles for its vehicle fleet. The planned changeover to purchasing green electricity will contribute to reducing CO2 emissions.

Employees provide new ideas

However, INTERSEROH does not just rely on taking technical steps to reduce its greenhouse gas emissions. Around 20 in-company sustainability ambassadors are developing new ideas for the company to protect the climate and the environment and encouraging their colleagues to behave in a more sustainable manner. Every year, for example, the “Interseroh Sustainability Week”, set up by the sustainability ambassadors, takes place, where employees can participate in clean-up days or mindfulness workshops and learn something about sharing concepts, repair cafés or waste prevention. The company also promotes eco-friendly behaviour amongst its workforce: employees who cycle or take public transport to work receive meal vouchers, for example. Since 2016, Interseroh has had a sustainability committee, which deals with the development of the company’s sustainability strategy.


As a company in the circular economy we are part of a growing global movement. Particularly in an industrial heartland such as North Rhine-Westphalia, this offers the opportunity to stimulate innovation, to act as an international role model and to create thousands of new jobs.
