Indian Waste : Different Scenario
1. High Biodegradable Content
2. Less Segregation
4. Lower Calorific Value
Integrated Solution with a focus on bio-degradables.
Policies and Data
Data Collection Design/ Implement Policies
Integrated Solid Waste
Management
Importance of Data collection
• For timely data and research analysis
• To ensure accurate estimation of technology solution
• Data observations can vary over time
• To ensure the success of the project
Consequences of improper data collection
Accurate data collection is essential to maintaining the integrity of research and ensuring the success of project
1. Inability to answer research questions accurately2. Inability to repeat and validate the study3. Distorted findings resulting in wasted resources4. Compromising decisions5. Potentially lead to complete failure of project
Consequences of improper data collection

Transportation issues for CNG
1. High pressure gas requiring larger spaces2. More weight and risk based 3. Low Fill Gas
Alternate: LNG
4. High capital costs of equipment
5. Lower energy density than LNG
