2020 – The SARS-CoV2 pandemic is causing bottlenecks in protective clothing in various facilities. TRIGEMA test shops are temporarily closed – 60% of revenues are lost. Owner Wolfgang Grupp guarantees all jobs despite difficult times. There are no short-time jobs or lay-offs. At the request of clinics and nursing homes, the company quickly converts production to reusable masks and protective coats. The production location in Germany offers immense advantages in terms of delivery times, which is why 2. 3 million masks were produced within four months. In late autumn, the demolition of an old company building begins. It should make way for a future workforce. In the same year, the TRIGEMA test shop opens in Rheinbreitbach. In addition, rapid charging stations for e-cars will be installed at 21 test shop locations.

2021 –The TRIGEMA test shop in Weitnau is modernized. Due to the lockdown, the textile industry has problems selling 500 million garments produced and destroys the new goods. The overproduction and destruction cause great horror. The production location in Germany is therefore repeatedly very popular. In March, the stationary shops are allowed to reopen. In a dominant market of overconsumption, TRIGEMA remains constant in its values. 100 % quality, 100 % made in Germany.

2022 – In February, Russia attacks Ukraine and there is war in Europe. The result is an energy crisis, which is also clearly noticeable at TRIGEMA.

2023 – TRIGEMA ventures into new territory and implements a cooperation with the streetwear brand Live Fast Die Young. The joint collection consists of 13 items, which stands out by Made in Germany. In the same year, TRIGEMA, together with the Hohenstein Institute, developed a test method for the release of microplastics during washing, which serves, among other things, to optimize its own sports range. The staff park is supplemented by a 100 sqm large terrace to be able to spend lunch breaks in the countryside. Five bee colonies have been calling TRIGEMA their home since May 2023. The resulting honey is sold under the quality mark Made in Germany in the test shop Burladingen. Due to the persistently high energy prices, an energy plan for the future is being drawn up. This includes further investments of 800,000 euros in the expansion of solar energy at the main plant in Burladingen. At the end of the year, the test shop Bispingen will be opened and the shop design will be renewed. A roughing machine makes TRIGEMA even more self-sufficient: Cuddly soft fabrics such as fleece can now be roughened themselves.

After 54 years of success, during which Wolfgang Grupp has led TRIGEMA in an incomparable way as the sole owner and managing director, his son Wolfgang Grupp Jr. as managing director and personally liable partner, his daughter Bonita Grupp as a member of the management board and his wife Elisabeth Grupp as a partner have been managing the company's fortunes since the beginning of 2024. The philosophy and values that TRIGEMA has stood for as a family business for over 100 years will continue to be the basis for the daily actions of the management.
