Step 1: Alternate structuring: follow the waste's 'life cycle':
Trace waste from generation (households/industry/commerce) → collection (often incomplete) → transport → treatment (rarely adequate) → final disposal (mostly unscientific open dumps) — the problem compounds at almost every one of these stages in Indian cities.
Step 2: Identify where the biggest gap is:
The weakest links are typically segregation at source and scientific final disposal — most Indian cities still rely on unsanitary open dumping rather than engineered landfills or waste-to-energy processing.
Step 3: Final Answer:
Following waste from generation through to disposal shows that Indian cities struggle most with source segregation and scientific final disposal, leading to the open, unmanaged dumping grounds that define the urban waste problem today.
