An observation note submitted by an amicus curiae before the National Green Tribunal has highlighted significant gaps in solid waste, legacy waste and liquid waste management across Assam’s 104 urban local bodies, including the Guwahati Municipal Corporation. 

More About the News

• The note questioned whether the State’s reported 100% waste collection and transportation translates into effective processing and scientific disposal.

Key Findings

• Underutilised processing capacity: Assam has a reported solid waste processing capacity of 1,925.38 tonnes per day, but processes only 1,370.30 tonnes, leaving substantial capacity unused.
• Composting shortfall: Biodegradable waste generation stands at 920.59 tonnes per day, against composting capacity of 766 tonnes per day.
• Legacy waste burden: Around 19.23 lakh metric tonnes of accumulated waste remain to be processed.
• Liquid waste concerns: The note identifies a wastewater processing gap of 418.65 million litres per day and reports that 8.646 million litres per day of industrial effluent enters drains.
• Guwahati’s challenge: The city faces a reported solid waste processing capacity gap of 316.37 tonnes per day, while waste continues to accumulate in landfills.

Way Forward

Assam needs plant-wise audits to identify why processing facilities remain underused, stronger segregation at source, improved compost quality and better arrangements for construction, demolition and sanitary waste. Authorities should also expand wastewater treatment, monitor industrial discharges and publish urban-body-wise performance data.

Exam Hook: Key Takeaway

Effective waste management depends not merely on collection infrastructure but on segregation, treatment, recycling, scientific disposal and continuous monitoring.

Prelims Practice Question

Which of the following is a key objective of the Swachh Bharat Mission–Urban 2.0?

(a) Promoting scientific municipal waste management.
(b) Expanding coal-based power generation.
(c) Replacing all public transport with private vehicles.
(d) Promoting untreated wastewater discharge.

Answer: (a) Promoting scientific municipal waste management.

One-line wrap: Assam’s waste challenge highlights the need to convert infrastructure and collection claims into measurable improvements in processing, pollution control and urban environmental health.
