  1. Within the Factory FenceKey Insights from Industrial Water Research Valerie Naidoo Water Research Commission • NCPC / DTi Industrial Efficiency Conference • ICC Durban 2015 • 22nd July 2015

  2. Global Risk Assessment (WEF)…..900 leaders

  3. Research focus in industry focus factory Water consumption Effluent production

  4. Industrial Research focus - summary Move towards not only meeting standards or municipal discharge requirements to treating to an acceptable industrial grade water and beneficiation

  5. Industry Overviews High water users High effluent producers

  6. Management (Alignment) • 3 Guideline documents to facilitate legal compliance with respect to Industrial waste management • In line with DEA National Environmental Management Act (NEMA): Waste Bill • Volume 1 – Industry Guide • Volume II – Contractors Guide • Volume III – Authority’s Guide • Review of Local Bylaws against Waste Bill Frameworks : eThekwini Case Study

  7. Management (Guidelines) • Technical Guidelines for Cleaner Production • Mining sector / General Cleaner Production (case studies) • Legislation • Understanding • Tools • Checklists • Case studies (local and international) • Guidelines for Waste Minimization Clubs • What • How to? • Training Manual

  8. Industry Overviews • 20 National Survey Types Reports • Overview • Legislation (local bylaws) • Water Use (SWU) • Wastewater Generation • Best Practices

  9. National Survey Data – Revision 2015

  10. Textile Industry: Treat & Reuse 2 1 1 6 6 2 3 3 4 4 5 5 Process Design Strategy Q RECYCLE KEY: ANAEROBIC ANOXIC AEROBIC PRODUCT FEED MEMBRANE FILTRATION ANAEROBIC ANOXIC AEROBIC EGSB Modified Ludzack-Ettinger (MLE)

  11. Industrial Water: Reuse of Brewery Effluent Technology Integration Approach CSR High Rate Algal Ponds aquaculture Brewery effluent hydroponics

  12. Water Efficiency and Wastewater Management Tools • Zero Liquid Effluent Discharge • Green chemistry • Waste Minimization • Life Cycle Analysis • Pinch • Water Optimization modelling • Water Footprints • Case Studies • Green chemistry – textile industry • Savings – general housekeeping • Recommend RO vs IEx • Water savings • >10% water savings (Johnson & Johnson and Eskom) • Test value for different sectors • Extractives vs retail vs energy vs beverage • Upstream – focus internal policy • Within fence – target the high water use operational activities

  13. Water Footprints Sustainability Discussions Sustainability Discussions Growing awareness that “water” needs to be considered in a broad range of decision-making processes File name

  14. Highlights • Overall, it can be concluded that water footprinting is indeed a useful tool that companies can use as a first estimation of their water use and impact. Figure 64: Water footprint components for the individual mines at Matla Figure 71: Total Water Footprint for the upstream and operations

  15. Highlights Figure 70: Components of the operational blue water footprint for 2009 Figure 68: Operational blue water footprint for Matla facility

  16. Water Footprints Take Home Message • Important – Business Risk • Policy • Public • Business • Operational Focus areas • Pinch • Water Optimization • Supply Chain focus • Retail – concentrate on agriculture SC • Beverage – concentrate on agriculture SC

  17. Future: Look within and outside the factory fence focus focus catchment catchment Supply chain factory Effluent production Water consumption
