Blue economy, Kenyan context
KDF Incinerator’s waste heat recovery solution
Benefits
Challenges
Future Trends
Conclusion

7. INTRODUCTION
Industrial waste, sewage and domestic waste have been flowing into rivers and other water masses polluting and making it unsuitable for use
Domestic waste has been the largest contributor to the urban centres Landfill menace in the country
All these streams of pollution do pose serious health risks on human, animals, plants and more, operating systems key in supporting our ecosystems

8. INTRODUCTION
Nairobi river

9. AIM
To apprise participants on the impact of applying alternative energy sourcing as a tool for facilitating pollution control and consequently enhancing BLUE ECONOMY opportunities

10. POLLUTION CASE DESCRIPTION
Major causes of pollution include;
Transport,
Manufacturing/ processing,
Municipal waste
Thermal energy generators
Natural effluent

11. POLLUTION CASE DESCRIPTION
Leading specific negative effects of pollution include;
Reduced visibility
Machinery fouling
Environmental damage (Deposition)
Aesthetic damage and
Health challenge

12. BLUE ECONOMY, KENYAN CONTEXT
Sustainable use of water resources for economic growth has not been achieved in Kenya
Associated activities include;
Fisheries
Tourism
Water management
Marine transport
Renewable energy
Climate change
Sea extraction

13. BLUE ECONOMY, KENYAN CONTEXT
There are numerous potential measures envisaged to mitigate the challenge, these may be categorized into;
Eco-friendly/ green measures
Technology innovations
Conducive legal framework
Community good will
Personal protection

14. KDF INCINERATOR’s WASTE HEAT RECOVERY SOLUTION
The incinerator project was initiated and later commissioned for use in This was for the purposes of managing waste at MAB Eastleigh
Through Energy Management and Environmental Management Policy (EMECP) program, energy audits were conducted in various camps within KDF and recovery of waste heat was identified as among energy saving opportunities presenting for exploitation

15. INCINERATOR’S BASIC OPERATING DATA
The MAB incinerator is operating with the following parameters:
Burns approximately 15 Tons of domestic waste per week
The domestic waste has recoverable energy value of 2.1MJ/kg
Burning chamber attain temperatures of approximately 500 degrees Celsius
The chamber burns for approximately 8hrs per day

16. KDF INCINERATOR’s WASTE HEAT RECOVERY SOLUTION
The energy solution is comprised of the following main components:
The heat generator (incinerator)

17. KDF INCINERATOR’s WASTE HEAT RECOVERY SOLUTION
The heat recovery unit (heat exchanger)

20. KDF INCINERATOR’s WASTE HEAT RECOVERY SOLUTION
A performance indicator:
Deliver 5,000 ltr at 53.00oC
This yield to an indicative annual energy saving of 60, kWh or Kshs 1,117,189.00
Current project performance compared to the design performance is 80.4%
Success attributed to; developing enthusiasm and confidence in viability and benefits derived from the project

21. BENEFITS The waste heat recovery system attract the following gains:
Reduction in high cost energy consumption
Reduction in pollution. A number of toxic combustible wastes such as methane gas, carbon monoxide, sour gas, carbon black off gases etc. when burnt in the incinerator serves dual purpose i.e. recovers heat and reduces pollution levels
Studies indicate Mombasa for example can harness 20,000 kWh of power daily, (Kshs 100M) annually

22. CHALLENGES
High capital cost
Need for Trained Manpower

23. FUTURE TRENDS
The project is being considered for replication in KDF camps
Collaboration for with organizations willing to apply the concept is being sort for a wider application
Bring on board large scale waste to energy power plants solutions

24. FUTURE TRENDS
Reppie Waste to Energy power plant in, Ethiopia

25. CONCLUSION
Therefore waste problem should not be a hindrance to Blue Economy activities but be converted into the much needed energy resource
Energy is not in shortage as we put it but is about how efficiently we harness the accessible energy
