The Innovative Group PROMIS Ltd. was founded in 1988 by a group of inventors as an attempt to implement new ideas of gas and fuel desulfurization and ideas for biogas and air purification. Over the course of 35 years, the Innovative Group PROMIS Ltd., using its own solutions and patents, has built and implemented several dozen desulfurization devices, according to investors’ needs and requirements, mainly for the needs of sewage treatment plants, agricultural biogas plants, oil and gas extraction, asphalt plants, as well as the cosmetic and pharmaceutical industries.

Designers of the Innovative Group PROMIS contribute to technical thought, participate in scientific life, publish articles and keep regular contact with numerous universities, including the Warsaw University of Technology, Wrocław University of Science and Technology, the University of Birmingham and the Pittsburgh Energy Technology Center.

Thanks to its innovative approach and effective implementation of biogas purification solutions, the Innovative Group PROMIS was among the Laureates of the Programme GreenEvo - Green Technology Accelerator created by the Ministry of Climate, Poland. Biogas desulfurization using the BIOSULFEX^® method was awarded by the project jury and the Ministry of Climate as BAT (Best Available Technology) for biogas purification.
