Borouge 1 project in Ruwais, Abu Dhabi

The petrochemical production plant in Ruwais, about 250 km west of Abu Dhabi City in the United Arab Emirates, is central to Borouge's operations. Borouge invested USD 1.2 billion to build the first petrochemical facility of the Middle East in Ruwais and equip it with Borealis' proprietary Borstar® technology.

Borouge 2 expansion

In 2010, under the project name of Borouge 2, Borouge tripled the polyolefins manufacturing capacity of the Ruwais plant. Approximately USD 5 billion was invested to enable Borouge to produce a total of 2 million tonnes of Borstar® polyolefins per year. The Borouge 2 project includes an additional ethane cracker, a third polyethylene unit, an olefins conversion unit (OCU) for converting ethylene to propylene, and two new polypropylene units, spearheading the company's entrance into polypropylene production.

Borouge 3 expansion

The Borouge 3 plant includes an ethane cracker, two polyethylene units, two polypropylene units, and a low density polyethylene (LDPE) unit. This expansion project was successfully completed in 2016 and has made Borouge the world's largest integrated polyolefins complex, with a total Borouge capacity of 4.5 million tonnes and a combined Borealis and Borouge capacity of 8 million tonnes. Borouge’s fifth polypropeneny plant, PP5, is currently in commissioning and will increase Borouge’s polypropylene production capacity by more than 25% to 2.24 million t/y.

Borouge 4 expansion

On 15 November 2021 Adnoc and Borealis announced the final investment decision for the Borouge 4 expansion. Borouge 4 will have an industry-leading focus on sustainability leveraging the capabilities of both shareholders. The facility will utilize, to produce a product portfolio focused on durable applications for energy, infrastructure, advanced packaging, and agriculture sectors. This unique technology, in combination with hexene comonomer, will enable the production of advanced packaging grades with up to 50% recycled polyethylene content. Subject to an in-depth study, a Carbon Capture unit that would reduce CO2 emissions by 80% could also be operational in time for Borouge 4’s start-up. The facility is also designed to capitalize on ADNOC’s recent initiatives on clean energy, decarbonizing its power supply through access to Abu Dhabi’s clean power sources. These initiatives are aligned with the UAE Net Zero by 2050 Strategic Initiative.

The new Borouge 4 facility will comprise:

  • An ethane cracker, with 1.5 million tons ethylene output per annum, which will be the fourth cracker in Borouge’s integrated petrochemical complex in Ruwais
  • Two additional Borstar® polyethylene (PE) plants, each with 700 thousand tons per annum capacity, using state-of-the-art Borealis Borstar third generation (3G) technology
  • A cross-linked PE (XLPE) plant of 100 thousand tons per annum capacity
  • A hexene-1 unit, which will produce co-monomers for certain grades of polyethylene
