The goal of ISO 50001 energy management systems is to reduce the amount of energy consumed by a business. This ISO standard provides an international framework for companies helping them to reduce their energy costs and cut greenhouse gas emissions. All relevant processes at a company are analysed and optimised to make energy consumption more transparent and so discover ways of sustainably cutting energy costs. The result is greater energy efficiency. Having implemented the system, TSR has been reducing its costs by using a structured method to record and evaluate its consumption of electricity, diesel and gas. This has not only saved the company money but also helps to protect the environment.
TSR is taking active measures to combat rising energy costs
It only really became obvious just how valuable energy management systems can be when energy costs began to rise so steeply. This is particularly true for electricity as legal regulations, such as those found in Germany, are leading to consumers having to pay more and more for their electricity even though electricity trading prices have been dropping for years now. Over the last three years, the number of levies and charges has increased year on year and currently lies at six different levies (the ‘EEG levy’ (renewable energy), the offshore liability levy, the ‘KWK levy’ (combined heat and power), the concession levy, the ‘Section19 StromNEV’ levy (power grid compensation) and the levy for interruptible loads).
The ongoing monitoring and optimisation of the facilities is part of the initiative to save energy
In 2014, these made up around 50% of the net electricity price. The ‘EEG levy’ has been pushing costs up the most, lying at 6.24 cents per kilowatt hour in 2014. Compared to the year before (5.277 Ct/kWh), it has risen by 18.25%. TSR managing director Bernd Fleschenberg put it in a nutshell: ”Achieving energy efficiency is extremely impor- tant in all areas of our business if we are to counteract this trend of ever growing electricity costs. This is the only way to guarantee that our processing equipment – for example our shredders, shears and balers – can be run in the most cost-efficient way so that we can compete with businesses operating in neighbouring countries such as Holland and Belgium where electricity is, on average, much cheaper. Saving energy is a must so that TSR can maintain its strong competitive position in the future, too.”

TSR identified this trend towards ever-rising energy costs and consumption very early on. In response to this, therefore, it decided to take action to achieve energy efficiency and, as a result, cut costs and so make an important contribution towards preventing climate change. Thanks to the recently introduced energy management system, TSR has been able to draw up a transparent overview of its energy consumption and develop key performance indicators as an energy benchmark. This includes indicators such as the number of kilowatt hours a machine consumes to process one tonne of material or how many litres of diesel an excavator requires for each operating hour. These will help them to identify inefficient ”consumers” and allow them to introduce measures to realise cost savings.
By introducing diverse optimisation measures, electricity consumption has been able to be reduced by 600,000 kWh.
TSR has succeeded in taking advantage of the energy management system and has already managed to reduce its energy consumption. And this success proves that these metal recyclers were right. In the first year alone, savings have been achieved by reducing the idle current. Moreover, an old diesel-run cable excavator in Duisburg was replaced with a new ‘balancer crane’ which consumes approx. 25% less energy than its predecessor.
A further measure introduced into the Duisburg facility has been to increase shredder throughput and, at the same time, cut electricity input by around 6 kWh per tonne. These savings were made possible by improving the mode of operation and switching to the so-called ”full-box shredding” which makes the most of the shredder’s capacity. Put in figures, electricity consumption has been able to be reduced by 600,000 kWh. Following this successful ”pilot test” in Duisburg, the plan is now to have introduced this energy management system throughout the whole of the company by the end of 2015. By doing so, the TSR branches can create an energy consumption benchmark to identify the most energy efficient processes and then transfer these, where needed, to other branches. To sum up: TSR is protecting the environment more than ever before and cutting its costs by planning ahead and acting proactively.
By increasing its energy efficiency, TSR is becoming more sustainable and cutting its costs
