SACAA Ash Conference 2019:

Accelerating Ash Beneficiation Conference

Dates: 14 & 15 August 2019
Venue: Sasol Place Auditorium, Sandton


Once again SACAA arranged an Ash Conference on 14 & 15 August 2019, that was hosted by Sasol at their magnificent Sasol Place in Sandton, which elevated the conference to a new height.
The focus of this conference was for the academics and industry to come and share the work done in ash research in line with the Phakisa Initiatives themes, as well as the large producers to share their strategies, thoughts and plans in support of beneficiation of ash in the drive to reduce the environmental footprint.

Some of the themes were:

  • Roads, Embankments and Concrete
  • Ash Exportation
  • Ash land and water reclamation Other applications

The conference was attended by some 110 delegates per day and had a high variety of industry, leaders in business, academics, entrepreneurs and ash marketers as well as emerging businesspersons. There were in total 20 speakers, 3 posters and some exhibitions. The calibre of the presentations was of a high standard, excellently presented and very topical to the work that needs to be done to achieve the Phakisa Initiative targets. It was also pleasing to see our Government colleagues present for the duration of the conference. The news that the Exclusion Regulations had been signed by the Minister was most probably the best news for Ash Beneficiation project to be executed. Another pleasing aspect was the involvement of senior management of the generators of the ash waste, which shows the accountability to the waste reduction initiatives is gaining momentum and emphases. The networking opportunities also allowed the delegates of the different academic institutions, businesses and generators to have meaningful discussions and building of relationships.
