UAE: Emirates Global Aluminium (EGA) has increased the amount of by-products it recycled in 2017 by nearly 25% to 96,000t from 77,000t in 2016. EGA’s smelting operations in Abu Dhabi and Dubai produce several by-product streams, particularly for use by the cement industry.

Spent pot lining (SPL), the used inner lining of the pots in which aluminium is smelted, is a source of fuel and refractory materials for the cement industry. EGA says it supplied almost twice as much SPL to UAE cement plants in 2017 than it produced. The aluminium producer also produces carbon dust that can be used as a fuel by cement plants. EGA recycled most of the carbon dust from its Jebel Ali smelter in 2017 and is seeking similar solutions for carbon dust from its Al Taweelah smelter.

UAE: Emirates Global Aluminium (EGA) and Arkan have agreed to test using spent smelter pot inner lining as a fuel in the cement producer’s kilns. EGA will provide between 1000 – 3000t of the pot lining to test as both fuel to fire the kiln and as refractory material to be incorporated in the finished cement produced at Arkan’s Al Ain plant, according to the National newspaper.

EGA produces about 37,000t/yr of pot lining and has already been testing the waste at other cement plants. The aluminium producer is jointly-owned by the Mubadala Development Company of Abu Dhabi and the Investment Corporation of Dubai.

UAE: Arkan Cement is set to sign a US$32m deal to set up a waste-to-power unit for its Al Ain plant. Martti Malmivirta, the chairman of Arabian Finnish Waste Refining (ARAFIN) that is partnering with Arkan Cement on the project, told the National newspaper that the 1000t/day unit will be the first in the Gulf Cooperation Council (GCC) region. A joint venture will be set up between Arkan and Arafin, which itself is a joint venture between Eera Waste Refining of Finland and Daud Group of Oman. The new fuel stream will substitute use of natural gas at the plant.

UAE: Bee’ah has selected Bulk Handling Systems (BHS) to design, engineer, manufacture and install a major retrofit to the company’s Sharjah Material Recovery Facility. The facility is currently the largest in the Middle East, with the capacity to process more than 500,000t/yr of municipal solid waste (MSW). The retrofit, scheduled to be operational in early 2017, will upgrade capacity and automation to increase recovery and total diversion.

BHS will implement its latest technologies, including BHS Bag Breakers and Tri-Disc screens, Nihot air separators and NRT In-Flight Sorting brand optical sorters. BHS Tri-Disc screens will replace existing trommel screens to improve separation efficiency, decrease energy consumption and increase throughput. BHS screens will also boost the recovery of organic materials by 50% to 600t/day. The system’s throughput will expand from 68t/hour to more than 75t/hour.

Nihot Single Drum Separators will separate heavy items such as bulky metals and inert materials from lighter, high-value recoverables such as fibre and containers. To increase film recovery by 100%, NRT SpydIR optical sorters are paired with Nihot rotary air separators, creating the FiberPurefilm recovery system. The FiberPure will detect and eject film, pneumatically conveying it away from the remaining clean fibre stream. The NRT SpydIR optical sorter is also being employed to increase PET recovery by 15%. Magnets and an Eddy Current Separator will increase ferrous and non-ferrous recovery by 25%. The BHS Total Control controls package will integrate pre-existing and new equipment, empowering the entire system with advanced SCADA technology.

“BHS is selected according to stringent criteria, including technical know-how and manufacturing experience, to ensure their products, methodological knowledge and business strategies match Bee’ah’s high standards. This agreement reaffirms BHS’ exceptional reputation as high quality manufacturers and experienced integrators of whole system solutions,” said Daker El Rabaya, MD of Waste Processing, Treatment and Disposal Bee’ah.
