BESIX commissions flagship sludge-to-biogas project in UAE

BESIX Middle East’s flagship sludge-to-energy project in the United Arab Emirates (UAE) has passed performance and reliability tests.

Designed and built by BESIX Middle East for Ajman Sewerage Company (ASPCL), the facility transforms sewage sludge into biogas, which is then used to generate heat and electricity that is used in the facility itself.

Since 2002, ASPCL has played a central role in managing the wastewater of the Emirate of Ajman. The company currently purifies 120 million litres of wastewater per day.

The facility, the first of its kind in the UAE, produces enough green energy to cover up to 50% of the electricity consumption of the ASPCL wastewater treatment plant in Al Jurf. The plant comprises two power generators with a combined capacity of 2.4 MW, which is equivalent to the energy consumption of 2,000 households in the UAE.

In addition to reducing the plant’s reliance on the public power grid and providing a circular solution, the digestion process allows for a significant reduction in sludge quantities while avoiding the uncontrolled fermentation of unstabilised sludge.

The contract for designing and building the sludge-to-energy facility was awarded to BESIX Group by ASPCL in 2019 and construction continued throughout the pandemic.

This is the third such project BESIX has successfully commissioned in just five years. In the Netherlands, the company has successfully implemented similar biogas production and energy recovery schemes, including 100% energy-neutral facilities.
