zero waste solutions

Our business model is based on the conviction that we have to conserve our resources and avoid wastage. Our zero waste solutions mission aims to establish a sustainable basis for meeting the increasing demand for resources from a growing global population and ensure that valuable resources are conserved. We are also rigorous about orienting our own internal processes on sustainability.

Environmental protection starts at home

We use ‘zero waste solutions’ to mean avoiding wastage – from the disproportionate consumption of material resources through to the inefficient use of time, capabilities and financial resources. So it’s only logical that we also design our internal processes to be as resource-friendly and efficient as possible.

Our corporate carbon footprint: 115,751 tonnes of CO2

Climate change is one of the greatest challenges of our time. At Interseroh, we also want to do our part to counter its effects. To establish a baseline, we again calculated all of our greenhouse gas emissions along our value chain in 2017, using the Greenhouse Gas Protocol Corporate Standard: an estimated 115,751 tonnes of CO2 were generated directly by our sites in 2017 (Scope 1), as indirect emissions, e.g. from electricity (Scope 2) and as other indirect emissions (Scope 3). The calculations also showed that the lion’s share of our corporate carbon footprint is generated by our upstream and downstream contracted services. Potential CO2 savings are to be found in particular in material transportation.

Our climate strategy target: 50 percent fewer emissions at our sites by 2025

Our services are already helping customers to cut greenhouse gas emissions and conserve resources. Yet our business activities also produce CO2 emissions. Our goal is to cut site-based emissions and therefore play our part in achieving the climate goal set in 2015 at the UN Climate Conference, namely limiting global warming to well under two degrees Celsius. To do so, we design internal processes and activities to be as resource-neutral and efficient as possible. We have used the calculation of our corporate carbon footprint to formulate our climate strategy and specific goals:

  • 50 percent reduction in emissions per site (Scope 1 and 2) by 2025
  • Continuous identification of potential for optimisation in logistics and working towards the goal of reducing logistics-related emissions
  • Annual savings of at least 5.5 million tonnes of resources and 800,000 tonnes of carbon dioxide equivalent by the services we provide

Reducing energy consumption

Compared to our baseline year of 2015, we managed to reduce our total energy consumption by around 6,300 MWh in 2018 – although our consumption rose slightly by 2.1 percent year-on-year. The increase in consumption can be explained largely by a rise in output at our most energy-intensive site in Eisenhüttenstadt. We are applying continuous improvement across the board to optimise our sorting plant processes and again lower energy consumption. Standard operating procedures and plant shutdown checklists also form part of our reduction strategies. Other measures to improve process efficiency include installing high-performance compressed air units with smart controllers, replacing fluorescent tubes with LEDs and deploying motion sensors.
