Climate-neutral company with sustainable solutions for plastics processing


SONOTRONIC GmbH develops components, standard and special machines for ultrasonic-based plastics processing with high quality awareness with the aim of helping to shape the industry in a more sustainable way. The innovative family-owned company is dedicated to the focus of achieving 100% climate-neutral machine manufacturing. To expand its climate protection measures, SONOTRONIC follows a modern sustainability strategy that optimizes processes and conserves resources and the environment. 

Climate-neutral company with sustainable and safe solutions for plastics processing


Norms, standards & climate neutrality

With its ultrasonic technology, SONOTRONIC promises a sustainable and future-proof joining technology for plastics. Processing plastics with ultrasonic not only has advantages in the process, but is also significantly more energy-efficient and environmentally friendly compared to processing with other thermal processes - in other words, it is green throughout. With the use of ultrasonic, only a quarter of the electrical energy required for production is needed compared to thermal processes. CO2 emissions are therefore reduced by around 75%. As a fully comprehensive supplier, the company offers a wide range of product solutions that contribute to climate neutrality: from ultrasonic components to machine concepts for the installation of fully automated production lines. The innovative developments and the production of the machines in compliance with high environmental standards have an active effect on environmental protection. 
The company is aware of its responsibility towards future generations and has acted accordingly. With the aim of achieving emission reductions, the successfully completed KEFF check defined the first step towards increasing operational energy efficiency at the Karlsbad site. An honest and transparent needs analysis is the prerequisite for deriving the necessary measures. 
The next step was to record the greenhouse gas emissions caused by the company's activities and, in cooperation with Fokus Zukunft GmbH & Co. KG, the climate impact was determined: According to the guidelines from the Greenhouse Gas Protocol, the process certifies SONOTRONIC GmbH a CO2 balance of 1,480.70 tons in the reference period of one year. To illustrate: On average, a person in Germany causes about 11.6 tons of CO2 per year through his lifestyle. Compared with other companies of the same size and in the same industry, the emission value of the ultrasonic special machine manufacturer SONOTRONIC in Karlsbad is in the middle range.
For the neutralization of the determined balances, according to the principle of the Kyoto Protocol "Mechanism for Environmentally Sustainable Development" greenhouse gases, which are produced in one place on earth and cannot be avoided, are to be compensated by climate protection projects in another place. With the purchase of 4,443 certificates, SONOTRONIC supports a bioenergy project in China, which was certified under the sovereignty of the United Nations. In this way, the ultrasonic special machine manufacturer underlines its climate neutrality at the Karlsbad site and lives up to its special responsibility as a generational company. The balanced carbon footprint becomes valid from the beginning of the year 2022 and extends until the year 2024. 

Ever since the company was founded, it has done everything in its power to meet the high quality demands in mechanical engineering as well as the development requirements in ultrasonic technology and has been certified according to several international standards, among others. For more than two decades, the company's environmental protection system in accordance with ISO 14001:2015 has defined processes and responsibilities in the company, which include planning, regulation, execution and control. SONOTRONIC was able to optimally structure the responsibilities by defining procedures and behaviors. The certification portfolio is supplemented by DIN ISO 9001:2015 in the quality management system. The globally recognized standard defines requirements for the QM system in order to detect errors at an early stage or to elicit weak points and deficiencies.

With the standard certification DIN EN 16247-1:2012, SONOTRONIC fulfills all requirements regarding methods and evaluation of energy audits and their results. The Energy Efficiency Directive provides for the systematic inspection and analysis of energy use and energy consumption in plants and buildings. The aim is to make energy flows in the company efficient and to identify opportunities for improvement. In addition, SONOTRONIC regularly undergoes sustainability assessments by EcoVadis, an online platform for holistic ratings in the field of corporate responsibility. SONOTRONIC currently scored 59 out of a possible 100 points, thus achieving a silver award.


Successfully implemented measures for CO2 reduction

SONOTRONIC has now been regarded as a specialist for ultrasonic special machines for almost 50 years - from design to production. The family-run company focuses on the domestic circular economy in its coordinated value chain. SONOTRONIC produces within regional supply chains, which both ensure short transport routes and require reliable and flexible partners. The company not only implements reduction measures in a sustainable manner, but also supports regional environmental projects with its know-how. Currently, the company from the northern Black Forest points to a 90% share of national suppliers, of which 45% come from the home state of Baden-Württemberg. The conversion to modern energy-saving LED lighting systems and the use of environmentally friendly electric forklifts are also among the measures that have already been implemented within the company. With controlled process flows in the recycling management, the recycling quota of the total waste volume in the company has meanwhile risen to 35% - from plastics and metal chips, to paper, cardboard and wood, sustainable waste avoidance and recycling takes place. With the installation of a document management system and sensible interfaces in the ERP system, the conversion to a digitalized and paper-free office has already taken place in the commercial departments.


Corporate Social Responsibility

As a regional specialist company in special machine construction, SONOTRONIC faces up to its responsibility and regularly supports social projects in the region. The primary goal is to sensitize the environment as well as employees to provide help in various forms. With the aim of integrating people with disabilities into everyday working life, the company has been cooperating with the HWK (Hagsfelder Werkstätten und Wohngemeinschaften Karlsruhe gGmbH) and the Murgtal-Werkstätten for five years. SONOTRONIC is also an active partner in three schools in the region. Under the motto "Wirtschaft macht Schule" (Business goes to school), the Karlsbad-based company has been accompanying young people on their way to their dream job since 2014. Through regional sponsoring of institutions and clubs, the mechanical engineering company also stays on the ball in sports. As the main sponsor of SVL Karlsbad, SONOTRONIC has been sponsoring the sports grounds of SV 1899 Langensteinbach since 2015 and, with this responsibility, is starting a long-term commitment for the benefit of young generations.
