    • Metallurgical Sectors
    • Petrochemical Sector
    • Brick manufacturing
    • All listed industrial sectors
    • Mining activities
    • Power generation
    • Road vehicle emissions
    • Biomass burning
  • Regional scale dispersion modelling of various sectors including:
    • Household fuel burning
    • Mining activities
    • Road vehicle emissions
    • Biomass burning
  • Identification and assessment of emission reduction strategies for key emissions sources in order to achieve acceptable and sustainable ambient air quality levels on the Highveld.

Development of revised waste classification and management regulations for south africa.

EScience Associates have been integrally involved (2009/’10), as part of an International project team, in the development of revised “Waste Classification and Management Regulations”, on behalf of the South African National Department of Environmental Affairs (DEA). The project is aimed at encouraging a paradigm shift amongst waste generators and managers in South Africa, through regulatory means, that will promote the diversion of ‘waste’ away from landfill and move it rather up the waste hierarchy through the promotion of opportunities for waste Reuse, Recovery and Recycling. The project is seen as a bold move away from current waste management practise (broadly viewed in the public domain as being obstructive to initiatives for beneficial use of wastes, where appropriate) by the DEA that will maintain standards for environmental protection and at the same time reduce the amount of hazardous waste being disposed of on land (landfill).

Bridging and Basic Training for Environmental Management Inspectors (Green Scorpions)
EScience Associates was part of the consortium that was selected to develop the EMI Bridging Training material including training manual and presentational material. After initial planning and information sessions, the consortium commenced preparation of first draft course materials including a website for uploading of drafts and comments through a discussion forum. In January 2006, the first full 11-day EMI Bridging Course was presented in Pretoria. This was followed by 11-day courses in Johannesburg (February 2006), Pietermaritzburg (March-April 2006) and Cape Town (May-June 2006).

As at June 2006, a total of 420 officials had completed the EMI Bridging Training Course. Based on course evaluation of the course occurred through daily tests, practical exercises and a 3-hour examination at the end of the course, approximately 75% of officials attained the 60% pass rate. EScience Associates was responsible for the Chapter relating to Routine Inspections for EMIs (preparation for inspections, site inspection activities, and good documentation practices). The EMI Bridging Training Programme was nominated was an IAIAsa Premium Project finalist for the year 2006.

Waste Minimisation and Treatment: - Treatment of brewery filter media
Development of brewery kieselgur filtration waste recycling process to enable the reuse of kieselgur waste generated by the South African Breweries (SAB Miller) generated by the filtration of beer before bottling. The project included the identification and development of kieselgur treatment processes to restore filtration and chemical adsorption qualities, evaluation of different treatment processes and feasibility assessment of the selected recycling process option.

Air quality Biomonitoring -: Hexavalent Chrome
First application of lichen bio-monitoring as an indicator of ambient air quality in South Africa where bio-monitoring of lichens were used to assess air quality in the Steelpoort Valley and assess the deposition of Chrome (VI) containing particulates from a nearby ferrochrome smelter. A world first in terms of lichen bio-monitoring as an indicator of Cr(VI) emissions.
