The responsible handling of our environment and the sustainable use of its resources are just as central to our ETO DNA as the advancement and long-term development of our employees and the enhancement of their quality of life and that of all people.

As part of our corporate strategy, we are therefore committed to responsible corporate governance that is based on the three pillars of sustainability: environmental, governance, and social.

Through our actions, we support the Sustainable Development Goals (SDGs) of the United Nations.

Sustainability is practiced at ETO every day  

 nachhaltigkeitsstatus EN NEU

The photovoltaic plant at the Stockach site produces approximately 1 million kWh of electricity per year and saves 1,272 tons of CO2 emissions. 


Sustainability is both a core competence and a vision

Sustainability and efficiency serve as essential guidelines concerning the functionality and performance of our products. As parts of drives, devices, or machines, ETO products ensure a reduction in energy or fuel consumption, leading to a decrease in CO2 emissions while enhancing performance at the same time. The use of raw materials and energy, as well as optimal recyclability, play a significant role in the development and manufacturing of our products. 

The ETO Sustainability Strategy outlines a defined course of action that is aligned with our vision of sustainably maintaining mobility for people and ensuring a livable planet by consistently enhancing safety, efficiency, and environmental compatibility through our products. All ETO sites have reached agreement on objective, measurable milestones to achieve this.  


ETO’s vision of sustainability   

We want to actively contribute to maintaining our planet as a livable, safe, and sustainable place. We do this for our employees and their families, as well as for future generations. To achieve this, we implement the highest environmental, energy, and occupational safety standards and commit ourselves to our social responsibility as a company.  


The ETO mission for sustainability 

We comply with all sustainability requirements, whether from our customers or from the legislator. We work safely – always and everywhere. We continuously reduce our emissions, taking into account our supply chains as well. We are improving our energy consumption through the introduction of state-of-the-art technology. 


Sustainability is part of our development concept 

Thanks to the measures implemented so far, ETO already outperforms the industry average in the sustainability rating of the automotive industry. However, this is no reason for us to relax, as our strategic goals are ambitious. The ETO GRUPPE aims to achieve climate neutrality at all its sites by 2039 and strives to completely avoid work-related accidents.

Our measures include reducing greenhouse gas emissions, the supply chain, the environment and energy, establishing high occupational safety standards at all ETO sites, and improving employee health.

One very fundamental objective is to raise the standards at all ETO sites to the highest level, despite the varying national legislations in some cases. 

milestones THG Neutralität EN NEUBy 2030, energy consumption is to be reduced by 30 percent, and all ETO sites worldwide are to be certified according to ISO 45001, the international management system for occupational health and safety.

In addition, at all sites, a share of at least 90 percent of local suppliers and reusable packaging for all production material suppliers should be implemented. 

Over the past few years, ETO has been carrying out intensive research in the area of the magnetic shape memory effect, significantly developing the material further and constructing actuators based on this. Today, ETO’s new MAGNETOSHAPE® is ready for use in initial series applications. Thanks to its unique advantages, the technology has the potential to replace electromagnetic and other actuator technologies in future.

Find out more about the one-of-a-kind MAGNETOSHAPE® technology and meet us in person at the Actuator in Bremen from 25 to 27 June, 2018.

Actuators and sensors for medical applications will supplement our existing portfolio. These new ETO products meet the industry's rising ecological and economic requirements.

The good prospects of strengthening ETO's foothold in the market also enhance our successful partnerships with long-standing customers who have trusted in our competence in medical applications and our absolute dependability for more than 25 years.

ETO has developed a coil and coretube module called NGx modular system in order to meet the individual requirements of our customers more quickly in the future.

The number of new components to be developed is low thanks to the modular system, so the production capacity is able to be freed up more quickly for new products.

In addition to optimised product development, the manufacturing of the products is also state-of-the-art thanks to new production concepts.

“The Heart of Motion” describes the core of what we do and what we work for. That’s why it’s important to question the “heart” of motion and to take a fundamentally new approach to it. The anchor of an electromagnetic solenoid or the rotor of an electric motor are perhaps the most common, but not always the most ideal solutions for a job.

Magnetic fields lead to strains in magnetic shape memory alloys. This enables drives to be implemented where motion occurs on the interior of the material and tribological interfaces are avoided. We develop innovative drive concepts based on this effect under the name MAGNETOSHAPE®, from the material and actuator to the mechatronic system – always with the aim of creating the technologically best solution in line with our customers.



Magnetic shape memory technology explained briefly


Magnetic Shape Memory technology explained briefly

Magnetic shape memory alloys are ferromagnetic materials that generate force and motion under moderate magnetic fields. The typically single crystalline alloys made from nickel, manganese and gallium are able to generate 6% strain under external loads. And they do this with frequencies into the low kilohertz range.

The magnetic shape memory effect was discovered in the mid-1990s. Over the past few years, ETO has been carrying out intensive research in the area of the magnetic shape memory effect, significantly developing the material further and constructing actuators based on this. Today, ETO’s new MAGNETOSHAPE® is ready for use in initial series applications. Thanks to its unique advantages, the technology has the potential to replace electromagnetic and other actuator technologies in future.

The purchasing department of the ETO GRUPPE has dedicated itself to being a competent partner for all those involved in the value chain to deliver a significant and sustainable contribution to the company success of the ETO GRUPPE.

ETO’s global purchasing organisation is derived from this dedication.

Purchasing production materials is structured according to product groups and is carried out locally by the independently operating ETO sites. The job of the local purchasing organisation is to secure a constant flow of material with cost-efficient acquisition from authorised sources of supply that meet quality standards.

In doing so, central product group management guarantees a group-wide and national strategic alignment, which in particular includes the use of synergies at the individual ETO sites.

In the ETO development sites, the supplier is accompanied by a project purchaser, who supports the supplier as a central point of contact during the development phase through to series production. Here we integrate our target suppliers in the development at an early stage.

We see our target suppliers as strategic partners for joint and sustainable company success.
