Dubai inaugurates 220 MW WtE plant: Crown Prince of Dubai Hamdan bin Mohammed Al Maktoum inaugurated yesterday a AED 4 bn (USD 1.1 bn) waste-to-energy (WtE) plant in Warsan that will generate 220 MW of clean energy, the Dubai Media Office said.

What we know: The 400k sqm plant will process and convert 2 mn tons of waste annually, providing clean electricity to power some 135k residential units. The facility, which is expected to be operational next year, is reportedly the world’s “largest and most efficient” WtE plant, Al Maktoum said on Linkedin.

Not the only WtE facility in Warsan: Earlier in May, Dubai finished constructing a 6 MW WtE biogas production facility at the Warsan Wastewater Treatment Plant. The biogas will be retrieved from the waste emitted by the water treatment process before being converted to energy and used to treat more water. The facility can generate some 44k MWh of electricity annually — enough to cover 50% of the treatment plant’s entire operational needs — and will lower operational costs by AED 320 mn over 25 years while reducing carbon emissions by 31k tons. Out of the 57k cubic meters of biogas waste produced per day, almost 55k can be retrieved to produce energy.

And there’s more coming: Two international consortiums — one led by Japan’s Marubeni and the other by France’s water utility and waste recycling company Suez — submitted proposals to the Emirates Water and Electricity Company (Ewec) and the Abu Dhabi Waste Management Company (Tadweer) last May for the development of a 900k ton capacity greenfield Waste-to-Energy (WtE) IPP facility in Abu Dhabi.
