Sustainability

At RKT, sustainability is ingrained in our culture. For years, we’ve prioritized prudent energy and resource use to safeguard both people and the environment — driven as a corporate responsibility rather than just financial motives. We’ve invested in various technical innovations, from optimizing cooling towers to switching to LED lighting. While our focus is on sustainability, many of these initiatives have also paid off economically, demonstrating they’re not only environmentally sound but also smart business choices. In one example, implementing a heat recovery system enabled us to save over 1 million liters of heating oil over ten years. Read more about this heat recovery project here.

The RKT sustainability journey began early in 2011 with ISO 14001 certification for environmental management. Soon afterward, we became one of the first companies in Germany to receive ISO 50001 certification for energy management. . Since then, we’ve continually identified opportunities to enhance sustainability across our operations. Continued sustainability progress is a defined responsibility led by our quality department, overseen by our Head of Integrated Management Systems.

CCF Reporting of RKT’s CO2 Carbon Footprint

Since 2019, RKT has voluntarily prepared an annual Corporate CO2 Carbon Footprint (CCF) report detailing the company’s greenhouse gas emissions for which a business is responsible. In recent years, RKT has succeeded in reducing its CO2 carbon footprint by 45%, primarily due to the change to green electricity in 2020. Many companies report only Scope 1 (direct emissions from energy generation) and Scope 2 (indirect emissions from purchased energy), which combined only account for 25% of the carbon footprint. The remaining 75% reported in Scope 3, which includes indirect emissions across the value chain, is more challenging for companies to control. RKT, though, also reports Scope 3 emissions and is actively exploring strategies to reduce them. Current initiatives include transitioning from air freight to sea freight to mitigate emissions in the transportation sector.

ISCC PLUS certification attests to sustainable circular economy concept

Our ISCC PLUS certification for circular economy and bioeconomy throughout the entire supply chain represents another building block in our sustainability strategy. It underlines how we are supporting the move to gradually replace fossil raw materials with recyclable, ecologically sustainable, raw materials – in our case, plastics.

We achieve this through mass balancing, which involves purchasing credits from the sustainable raw material portfolio of ISCC PLUS-certified manufacturers. We can then use the value of these credits to manufacture ISCC PLUS-compliant components for customers who require sustainable products.

A product can only receive the ISCC PLUS label if all parties in the supply chain, from granulate manufacturer to injection molding company, are also ISCC PLUS-certified. To that end, we have adapted processes in procurement, incoming and outgoing goods, production, and employee training so that they are aligned with our mass balancing efforts.

Together with our customers, we want to be pioneers in increasingly embedding the circular concept in production processes. Why not join us? Every client company that opts to manufacture using sustainable plastics increases the proportion of recyclable raw materials that we use.

Sustainability Projects

RKT is creative and regularly identifies new opportunities for conserving resources and energy. We’ve implemented over 100 measures to enhance sustainability across our operations. Check out a few key projects to learn more about our sustainability efforts:

Heat Recovery

Injection molding processes generate significant waste heat. RKT previously discharged this heat from chillers externally, but in 2012, we developed an innovative concept to recover and utilize the waste heat for our offices and logistics areas. As a result, our reliance on oil-fueled heating systems has drastically decreased. Today, we resort to oil heat only during exceptionally cold weather or when the recovery system is offline. This initiative enhanced our sustainability while yielding significant energy savings. The additional system equipment paid for itself in less than 3 years.

Numbers:

The heat recovery initiative saved over 1 million liters of heating oil over 10 years. Just for comparison, a typical single-family home consumes roughly 2,000 liters of heating oil a year.

Per GEMIS (CO2e=CO2 equivalent), this is also a savings equivalent of roughly 2,600 tons of CO2.

Lighting

In 2012, RKT started the conversion of all shop floor lights to LED, resulting in significant energy savings. ROI was achieved in less than nine months.

Newest Facility: Strong Investment in Energy-Efficient Technology

Our newest facility was designed for energy efficiency from the outset. RKT is making massive investments in state-of-the-art, highly efficient production machinery, refrigeration, and compressed air technology.

New Building: Using the Sprinkler Tank to Store Cold Water

In our latest production facility, the sprinkler tank serves as a reservoir for cold water to support the operation of six new injection molding machines. Managing energy storage, rather than generation, becomes critical during periods of surplus energy production.

Cooling Tower Optimization

Optimizing the cooling tower in 2017 allowed RKT to reduce its water consumption by 022 to over 50%. The previous open cooling tower, which required biocides and chemicals to prevent legionella contamination, was converted to a closed system, not only significantly decreasing water usage but also minimizing chemical usage. The project reduced water usage by 3,000 cubic meters, or 3 million liters per year. For comparison, a typical four-person household consumes around 186 cubic meters or 186,000 liters of water per year.

Other Sustainability Measures (of Over 100 individual measures):

  • Complete switch to green electricity in 2020
  • Circulation pump replacement
  • Replacement of older systems with more energy-efficient machines
  • Optimization of compressed air consumption
  • Frequency control of facility ventilation
