The document discusses strategies for improving city management systems based on examples from Philadelphia and Portland in the US. It proposes implementing a more effective waste disposal and recycling system that relies on segregating garbage at its source. The city commissioner was impressed by how the two US cities generate revenue by recycling waste into products like tissue paper and plastic cups. Moving forward, the city will focus on creating public awareness about separating dry, wet and compostable garbage. This would help the city body reduce the load on landfills and potentially generate income.
