In 2022, Greiner entered the recyclables business for the first time with the purchase of a Serbian recycling company, thus setting a milestone in the field of the circular economy. Some recycled materials, all of which previously had to be bought in from external suppliers, will now be produced in house. Greiner expanded its areas of activity in the previous year with several investments handled by the Greiner Innoventures innovation hub. Examples of these investments include MATR, a start-up that offers recycling services for mattresses in the hotel industry; Hempstatic, another start-up that produces soundproofing panels made of hemp; and new subsidiary Greiner Zeroplast, which develops material for bio-based plastics. All acquisitions and investments are united by the fact that they contribute to Greiner’s sustainability strategy.
