Eco industrial park

  1. 1. Turning Industrial Area into an Eco –Industrial Park: Case study of Harare Presentation by Taurai Mpaso R113641T Supervisor : Eng K Mugwindiri
  2. 2. PROBLEM STATEMENT Problems More waste in land fills Money lost in form of waste Extensive use of virgin materials Waste - loss of something valuable that occurs because too much of it is being used or because it is being used in a way that is not necessary or effective (Merriamwebstardictionary.com)
  3. 3. Aim •Assessment of Harare industrial sites setup and practices to develop possible industrial symbiosis connections.
  4. 4. OBJECTIVES • To identify current eco-related activities • To identify common inputs required, by products, wastes produced and the potential major users of the by-products and waste in the same industries • To identify possible material exchange with the view of improving energy efficiencies, recycling water and materials, waste management and dematerialisation
  5. 5. ECO INDUSTRIAL PARKS Resource (Material) Flow in Today’s Society Ideal Resource (Material) Flow

  9. 9. Development of Prototype Due to geographical location of the identified potential members the best type was a Virtual Eco Industrial Park The final model is a combination of two development scenarios, it is a combination of existing organisational relationships and Anchor tenant model. The models take the following assumptions: • Members chosen are willing to participate fully • Technical feasibility • Economic feasibility • Portfolio feasibility
  10. 10. Stage one: Baseline Activities Cement industry (Lafarge) Fertiliser and chemical industry (ZimPhos) Power Generation (ZPC) Capacity 450 000 tonnes per annum Current substitute raw material use 0.18% fly ash and 9.6% for brick rubble. Processes 103kg of coal to produce a tonne of cement And this produce a tonne of CO2 Capacity 200 000 tonnes of fertilisers and 65 000 tonnes of phosphoric acid Current outputs Operating at 20% capacity Process 325 000 tonnes of gypsum is produced Deposited in 2 dumps Capacity 50MW of electricity Current 25MW of electricity Process 16 250 tonnes fly ash 4 225 tonnes bottom ash 65 000-81 250 tonnes of coal
  11. 11. Stage two •The stage identifies production practices and recycling opportunities that can provide economic and environmental benefits if implemented independently by each member. •For each major player identified possible methods of limiting the pollution impacts of their production methods are proposed.
  12. 12. Stage 3: Industrial Symbiosis Key Industry located in Msasa Industry located in Granite site Industry located in Southerton Industry located in Workington Cement industry (Lafarge) Fertiliser and chemical industry (ZimPhos) Power Generation (ZPC) Fly ash 11 250 tonnes Gypsum 13 000 tonnes CSA specification of fly ash Type F : 8% CaO Type CI : 8-20% CaO Type CH : > 20% CaO Road Construction Max 25% mass ratio fly ash Increase fly ash ratio to 2.5% and Gypsum composition To 4% Remaining fly ash Municipal solid waste (fuel in the kiln) Effects of using MSW fuel CO2 emissions reduced avoids landfilling waste reduces methane emissions

  16. 16. Recommendations Technological development Members acquire technologies specifically to suit the network formulated Development of administration centres Formulated and financed by members from companies and interested groups Government Intervention 1. Legislation modification 2. Funding initiative 3. Spear heading Project 4. Resuscitation of transport network
  17. 17. Conclusion Eco Industrial Parks are the way to go as it will deal with 15%-20% of waste-material that will end up in dumpsites
