Sustainability as a competitive edge: one step ahead with PLM

Sustainable thinking is no longer a “nice-to-have” – regulations and customer demands have made it a central pillar of modern innovation. A growing number of companies are realizing that ecological responsibility and economic success can go hand in hand. This is especially evident in product development: where cost-effectiveness used to dominate, sustainability has emerged as another key factor.

The right balance between economic and ecological aspects

While cost and efficiency remain crucial, staying competitive in the future requires taking the environmental balance into account when making business decisions. The challenge lies in finding the right balance between economic performance and ecological responsibility. This is most successful when sustainability is considered from the very beginning – at the design stage – rather than at the very end.

Why the product development process is crucial

Around 80% of a product’s environmental impact is already determined during the development phase. Decisions about materials, manufacturing processes, energy use, and recyclability made during this stage play a decisive role. Leveraging reliable and transparent data in the decision-making process enables companies to lower the environmental impact of their products.

LCA vs. PCF: Two key terms briefly explained

Anyone involved in sustainable product development will inevitably encounter these two concepts:

Life Cycle Assessment (LCA): The assessment of a product’s environmental impact throughout its lifecycle, from raw material extraction to disposal.
Product Carbon Footprint (PCF): The environmental footprint of a product, expressed in CO₂ equivalents. The PCF is often part of a broader LCA.

Implementing sustainability directly in the PLM system

CONTACT’s sustainability solution allows this environmental data to be recorded and used directly in CIM Database PLM. This enables a systematic evaluation of materials, processes, and product structures. Whether entered manually or imported automatically from environmental databases, a product’s environmental impact can be analyzed and improved directly within the system.

Asset Administration Shell: a key to data exchange in the supply chain?

Sustainability is not a solo effort. Especially for complex products involving multiple suppliers, effective data exchange is crucial. This is where the concept of the Asset Administration Shell (AAS) comes into play – a standardized representation of digital twins for industrial components.

Using AAS submodels like the Carbon Footprint, companies can communicate environmental data in a standardized way, both internally and externally. This creates a seamless data foundation across the entire value chain. Using submodels like the Carbon Footprint, companies can communicate environmental data in a standardized way – both internally and externally, enabling them to integrate data from purchased components.

Three key takeaways:

Sustainability starts with engineering, where crucial decisions are made.
Standardized data formats enable the integration of environmental data into the product lifecycle.
With IT tools like CONTACT Elements Sustainability Cloud, companies can not only plan eco-friendly operations but also implement sustainability early in the development process.

Conclusion

Developing sustainable products is no longer a vision for the future – it’s a reality today. Companies that adopt the right tools at an early stage and rely on standardized processes gain not only ecological advantages but also economic benefits.

The Digital Twin at the Center of Renewable Energy

According to the German Wind Energy Association (BWE), the share of wind energy in German electricity production this year is 27 percent, and in 2020 wind energy even represented the most important energy source in the German electricity mix. In total, more than 31,000 turbines have been installed, saving 89 million tons of CO₂ equivalent in 2019. Wind power is thus a mainstay of low-CO₂ and sustainable energy generation and makes an important contribution to the energy transition. Further increasing yields while reducing maintenance costs is therefore of great importance.

Increasing the efficiency of wind farms with smart systems

Digital Twins are the central element in exploiting the full potential of wind power and maximizing yields. Driven by the vision of creating a data-based development tool for the wind industry, the WIND IO joint project, funded by the German Federal Ministry for Economic Affairs and Energy, started a year and a half ago.

Under the leadership of the Institute for Integrated Product Development BIK at the University of Bremen, we are working with several consortium partners to build research facilities as cyber-physical systems and retrofit them with sensors, electronics and computers known as IoT gateways. This makes it possible to digitally map all the operating information of the real plant and combine it on a digital twin. The operating behavior can be simulated on the basis of the Digital Twin, which in turn provides insights for further optimization of the wind turbine. The Digital Twin not only provides information about the current energy yield, but also offers a comprehensive overall picture of the condition of each individual turbine.

Improved installation, maintenance and overhaul processes

The information obtained can be used, for example, to optimize maintenance and overhaul processes. For example, the data makes the aging process of components transparent at all times and automatically triggers an alarm if defined limit parameters are exceeded. The Digital Twin also uses the operating, environmental and weather data collected to determine a favorable time for maintenance of the plant. Ideally, this should be carried out when there is little wind, so as not to be at the expense of energy generation.

Both statistical methods and Artificial Intelligence (AI) models are used for the calculations. These methods also help to determine the best time to assemble a wind turbine, since the rotor blades can only be installed under certain conditions. For this purpose, in addition to weather data, additional parameters such as the vibration of the tower are included in the calculations.

Digital Twins for a sustainable industry

The WIND IO project vividly demonstrates the potential of digitization and especially the concept of the Digital Twin. In addition, companies can use their data to simulate entire production and operating cycles. This makes it possible to minimize resource consumption, reduce energy consumption and at the same time coordinate production steps more effectively and optimize transport routes. Concepts such as the Digital Twin and data-intensive analysis methods are thus essential for a gentle and efficient industry.

With the data from a digital twin, companies can increase the efficiency of energy-intensive production facilities. Especially when they also use AI. The added value that this combination creates for energy management in companies is explained by Dr Nicole Göckel and Johann Heinrich in the technical article ‘Increasing yield with digital twins’.

Successful IoT business: just a question of standards?

There are days the little things in life make me happy. When my microwave broke last week and even a repair couldn’t save it, it took me less than five minutes to solve the problem: simply selected a new model on the manufacturer’s site using my smartphone, ordered it and paid via PayPal. Three days later it was unpacked, plugged in and running. The ease of this process illustrates two things:

digitization makes it incredibly easy for us to handle even extensive processes quickly.
I didn’t ask myself whether the microwave would also fit into my power socket and whether it would meet the usual standards for radio interference suppression, hazardous substances, etc.

Anyone who has ever traveled abroad knows that this lack of concern is not a matter of course. In the case of power sockets, the right time was simply missed to ensure global standards. In the meantime, the implementation of a standard would cause so much cost and electrical waste that it is no longer practicable.

Unimaginable that something like this could happen again to our highly developed society… or could it?

Digitization is opening up new business potential. The focus is shifting from the exchange of physical goods to the exchange of information. When I buy my microwave, it’s not just the manufacturer who earns money, but also the online payment service PayPal. And that is solely through the exchange of information. Digitization is also creating the basis for new business models in industrial companies. This is shown by a recent study by Sopra Steria and the F.A.Z. Institute. More and more machines and systems are being networked via IoT platforms in the industrial Internet of Things in order to determine performance data or offer product-related services. This is a development that has taken hold around the globe and is thus giving rise to many solutions with different data models and integration options. This allows us to draw a worrying parallel to the connector mess mentioned above. Companies that want to drive their digital business forward quickly lose their orientation here when choosing an IoT solution that is suitable for them. After all, how future-proof it is depends largely on how well it can be connected to other systems and data sources.

Global standards for sustainable digitization

Serious initiatives here give hope for an international standard in the industrial Internet of Things. The Plattform Industrie 4.0, for example, has developed the concept of the management shell, which is to be understood as the digital representation of a device. It makes it possible to address machines with all the necessary information and functions. For example, I could develop an app for my microwave, interact with it, display the instructions for use, and set the power intensity or duration via smartphone. If the manufacturer of my washing machine also provides the information and functions of this device according to the management shell concept, it is no effort for app developers to integrate other devices into their application. This manufacturer- and system-independent interoperability paves the way for the future of Industry 4.0.
