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
