Leveraging advanced waste to energy technologies

  1. 1. The 3E Solution to W2ESustainable waste to energy by focussing on the 3 Es<br />EAI Presentation at RenewCon, Mumbai - Sep 30, 2011<br />NarasimhanSanthanam<br />Energy Alternatives India – EAI<br />www.eai.in<br />
  2. 2. About EAI<br />Aspires to be a catalyst for the Indian renewable energy and cleantech industry<br />Dedicated focus on renewable energy and cleantech for India<br />Diversification, feasibility studies, market entry strategy, business intelligence<br />Founded by professionals from IITs and IIMs<br />Based out of Chennai<br />More from www.eai.in – see also our club, forum, mailing list…<br />www.eai.in<br />
  3. 3. The 3E Solution to W2E<br />What are the problems with waste-to-energy?<br />Why these problems?<br />How can these problems be solved?<br />How can technology be part of the solution?<br />What advanced technologies are emerging?<br />How could these advanced technologies provide a sustainable W2E solution?<br />How do we see the future?<br />www.eai.in<br />
  4. 4. Waste to Energy and the 3 E Problem<br />Environmental - Not environmentally benign (Planet)<br />Exclusivity - Does not benefit all societal stakeholders (People)<br />Economics - Still very costly (Profit)<br />www.eai.in<br />
  5. 5. Why these problems?<br />Misalignment with nature - Nature can convert waste to more value at less cost<br />Centralized paradigm – Waste generation is distributed, why energy generation centralized?<br />Thinking of waste as waste – My waste is someone else’s value!<br />www.eai.in<br />
  6. 6. How can these problems be solved?<br />Segregate at the gate (! – Make it easy to change habits)<br />Cradle to cradle mentality (!-Destroy less, recover more)<br />Recognition that waste is just value in a different form (! – Emphasise recycling, identify markets for co-products)<br />It’s the society, stupid (!- Involve stakeholders at every possible stage – government, rag pickers, local communities, farmers…)<br />Get local (! - Devise methods for distributed energy recovery at high efficiencies to recover energy close to generation)<br />Not just tech, but bio+tech (! - Identify recovery methods that combine the strengths of biotech and engineering)<br />www.eai.in<br />
  7. 7. Technology is…only part of the solution<br />Market<br />Waste is value<br />Cradle to cradle<br />Society<br />Segregate at the gate<br />It’s the society, stupid! (involve stakeholders)<br />Technology<br />Get local (DEG)<br />It’s bio+tech<br />www.eai.in<br />
  8. 8. Technologies/Processes for W2E Today<br />www.eai.in<br />
  9. 9. W2E Technologies - Pros and Cons<br />www.eai.in<br />
  10. 10. Technology Fit with Suggested Solutions<br />www.eai.in<br />
  11. 11. Technologies/Processes for W2E in Future<br />www.eai.in<br />
  12. 12. How do we see 3E in the future W2E tech?<br />Use of recycling and composting synergised with energy recovery<br />Incineration being phased out<br />Anaerobic digestion becoming cheaper and overcoming operational deficiencies<br />Gasification going towards smaller scales (this is more a hope!)<br />Pyrolysis gaining increasing acceptance<br />Combinations of routes – AD and pyrolysis for instance (AD for biodigestible organics and pyrolysis for plastics etc.)<br />Ultimately, trying to address all 3 Es<br />www.eai.in<br />
  13. 13. Waste is just value that we are too stupid not to use – Albert Einstein<br />www.eai.in<br />
