In 1990, BIPROMET completed the ownership transformation process and became a joint stock company - BIPROMET SA. However, due to the political transformation period there was a downturn in the economy, especially in the heavy industry. At that time, the demand for project design in the scope of new investment projects was reduced. At that time, BIPROMET undertook modernization tasks of the existing technological lines, as well as intensified its activities towards the needs of the iron, steel, mining, glass and general construction industries. An immediate consequence was the expansion of activities to the complex investment execution services market. In 1992, the first investment in the “turnkey” system - "Julian" Fine Coal Enrichment Plant in Piekary Śląskie - was completed. In the scope of general investment implementation, BIPROMET was cooperating with Przedsiębiorstwo Budowlane Przemysłu Węglowego from Katowice, transformed into PB Katowice SA. Later, intensified activities led to the company's involvement in the BIPROMET structure. As a result, dynamic changes in the economy have resulted in BIPROMET's commencement of providing comprehensive services that cover the scope of General Designer, Contract Engineer, General Investment Contractor and Contractor or a Project Team Partner at each stage of an investment process, focusing on industrial construction and large investment related to environmental protection.
The experience of working with the industry, which is the main emitter of air pollutants, led to intensified efforts to seek innovative solutions in the field of air, water and waste water treatment. BIPROMET's design offices continued to work on solving pollution problems. In 2000, as a result of acquisition of the OPAM Design, Supply and Realization of Air Protection Facilities Company in Katowice, BIPROMET organizational structure acquired additional units specialized in dust extraction and flue gas cleaning from industrial production processes. Reorganization activities were undertaken, and the scope of design work was expanded with technologies dedicated to removal of contaminated gases and fumes for cement plants, foundries, power plants, coke plants, steel works and non-ferrous metal industries.
