Borouge 4 is a major petrochemical expansion project under development at the Ruwais Industrial Complex in Abu Dhabi, United Arab Emirates. Developed by Borouge, the project represents one of the largest industrial investments currently underway in the UAE. The primary objective of Borouge 4 is to expand the company’s polyolefin production by integrating a world-scale mixed-feedstock steam cracker with ADNOC’s refinery. This expansion will increase annual production capacity by approximately 1.4 million tonnes, transforming the Ruwais site into the world’s largest single-site polyolefin production complex.

The SALCOS DRP 1 is a direct reduction iron plant developed by Salzgitter Flachstahl GmbH at the Salzgitter steelmaking site in Germany. The project involves the construction of a hydrogen-ready plant based on Energiron ZR technology, capable of producing over 2 million tonnes/year of DRI using natural gas and hydrogen in flexible proportions. Its objective is to progressively replace the traditional blast furnace–coal route with low-emission steel production through the DRP-EAF route, reducing CO₂ emissions and supporting the decarbonization of the steel industry.
