We protect
our environment

As a manufacturer of ecological products, systematic energy and environmental management is part of our company’s DNA – and a firm component of all of our processes. We make continuous investments in innovative technologies and systems in order to reduce emissions, wastewater and waste as much as possible. Our partners are certified in accordance with ISO 50001 (energy management), 140001 (environmental management) and BRC (hygiene management). You can find more information and specific application examples on the following pages.

Sustainable production at Klingele – powered by the sun:

  • 4 PV systems with a total output of 3,801 kWp
  • Consumption of external electricity reduced from 77% (2000) to 47% (2017)
  • More independence from volatile energy markets
  • Plants Delmenhorst and Werne: 20% self-sufficiency with energy
  • CO2-emissions reduced by 1,100 tons (group-wide)

Powered by the sun: Solar energy strengthens independent energy supply

Case Klingele Papierwerke, Germany

Photovoltaics (PV) have attracted the attention of citizens, businesses and governments all over the world. According to the industry association Solarpower Europe, the solar industry managed to penetrate a magical frontier with a global expansion of 102.4 gigawatts in 2018. With 11.3 gigawatts, the PV market in Europe recorded growth of 21%; for 2019, Solarpower Europe even predicts an increase of 80% to 20.4 gigawatts.

Germany is the largest PV market in Europe – and will remain so in the next few years. Klingele implemented its first system at its headquarters in Grunbach back in 2009, meaning that the company can still benefit from the high feed-in tariffs granted during the introduction of the EEG subsidy in Germany. All of the electricity generated by this system is therefore fed into the grid. Since the feed-in tariffs were successively reduced and are now well below current electricity prices, the motive of self-sufficiency now prevails. For this purpose, the new paper warehouse in Grunbach will now be equipped with a cutting-edge system with a capacity of 238 kWp (kilowatt peak: indicates the maximum output in kilowatts (kW) a photovoltaic system can provide). Parallel to this, the construction of a new logistics centre at the Werne site will give Klingele the opportunity to structure its energy supply in a more sustainable and cost-efficient manner. Here, first the old and then the new hall will receive a new PV roof. Together, both systems will deliver a total output of 1.5 MW. In Delmenhorst, Klingele “crowned” its new bulk storage warehouse with a PV system in 2016.

These are investments that certainly pay off – even if Germany isn’t exactly fringed by the Mediterranean. Klingele has reduced its external electricity consumption from 77% in the year 2000 to 47% in 2017, thus becoming less dependent on fluctuating prices on the energy market. In Delmenhorst and Werne, for instance, the new systems will enable Klingele to provide up to 20% of its electricity supply itself, saving approx. EUR 165,000 per year in each plant. Through its own generation of clean energy, Klingele also reduces its environmental burden by saving 1,100 tonnes of CO2 emissions across all plants.

Reason enough to continue to exploit the sun as an energy source. And if we turn to the topic of electromobility, Klingele already has a charging infrastructure for electric vehicles at its headquarters in Grunbach. After all, it is widely known that e-mobility is only truly sustainable when based on clean energy. Klingele is creating framework conditions to make this happen – today.

State-of-the-art water treatment - formula of success:

  • Integration of an aeaerobic digester
  • Integration of a modern (and bigger) centrifugal separator
  • Change of chemical additives – higher quality, reduction of cost

GRI 306: Waste by type and disposal method

Cart-One installs new water treatment plant

Case Cart-One, Italy

Cart-One’s Mezzani plant is equipped with a chemical-physical purification plant for the treatment of industrial wastewater: This consists of flexo wastewater generated by the printing units in the flexographic printing machines and starch water coming from the gluing units in corrugating machines. The treatment process generates sewage sludge that has to be disposed of as special waste – and on the other hand, purified water which is reused in the production of starch glue for bonding the cardboard in the corrugation phase.

A process that had to be revised: in 2017, Cart-One experienced an increase in the quantity of wastewater that had to be treated, while there was considerably less water available that could be reused for the preparation of starch. The latter was mainly due to the need to improve the starch quality, requiring a higher quantity of pure water for its preparation. As in many cases, the customer was the driver behind this development – as food safety issues are raising ever more concerns in the market, the reuse of wastewater in production processes is closely scrutinized by experts and relevant authorities. Apart from that, better bonding performance and constant starch quality improves product quality and production processes. As a consequence, the cost of disposal of excess water soared.

To overcome this increasing challenge, Cart-One decided to install a new industrial water treatment plant. Starting with the original flocculation and centrifugation chemical-physical treatment plant, an anaerobic digester was added. Furthermore, the centrifugal separator was replaced by a more modern and larger version. Finally, the chemical additives were changed to enhance quality and reduce costs. Well-considered measures that led to very satisfying results: the treatment process generated extremely highquality water, allowing it to be re-used for production or discharged in the local canal without impact to the environment. Cart-One achieved the perfect compromise between cost, water quality and recyclability – a benefit well worth the investment.
