At Prolactal thinking about tomorrow’s world, today is more than just a matter of following contemporary trends. Our company has been operating at Net-Zero since as early as 1984.

All our facilities are equipped with heat recovery, exhaust air filters, and cooling systems with process cooling. In addition, we only source green electricity and utilize our dairy by-products in biogas facilities. Our own flotation system not only efficiently and reliably pre-treats any wastewater, it even ensures wastewater quality above the local water purification plant’s legal requirements. Our own treatment plant is currently under construction – it will further relieve the local treatment plant in the city of Hartberg.

Furthermore, Prolactal proudly refers to its certifications according to the Energy Efficiency Act, the EN 16247-1, as well as SEDEX, which guarantee ethically sustainable manufacturing in the supply chain.
