Aluminium dross recycling innovation can achieve zero waste

US firm Harsco Corporation announced its subsidiary Altek is now able to provide complete end-to-end dross recycling. This enables the global aluminum industry to maximise aluminum recoveries. 

Altek is the first provider of a commercially viable and fully scalable in-house salt slag recycling solution available to the aluminum industry. The AluSalt salt slag processing technology enables aluminum producers to recycle metallics and salts, recover other non-metallic products. Altek’s new dross recycling method manages to recover more than 45% aluminum than has been traditionally possible.

Moreover, this solution addresses one of the largest environmental concerns within the aluminum market, argues Ian Johns, managing director of Altek. ‘We are providing modern solutions to age-old problems, drastically reducing atmospheric pollution and pushing the aluminum industry to a zero-waste scenario through sustainable methods of producing aluminum,’ he says. ‘Our latest technology is designed with Industry 4.0 in mind, driving the digital transformation.’

‘Every cast house is an opportunity for innovation, and we are delivering end-to-end solutions that improve cast house operations, including aluminum dross processing systems,’ comments James  Herbert, global sales Director of Altek. ‘As we hold a deep understanding of the  process, we are also uniquely equipped to find solutions to customer problems and customize our variety of offerings to meet customer requirements.’

Harsco projects 40% growth in demand for aluminum between 2019 and 2050. The company acquired UK-based Altek in May 2018 to expand the metal recovery by-product reuse capabilities of its environmental division, Harsco Environmental, into the aluminum industry. The list of customers using Altek equipment spans over 600 locations around the world.
