1– Solid Waste & Legacy Waste Management –Katihar
Source Segregation:- Katihar Municipal Corporation mandates separating waste into four streams—wet (biodegradable), dry (recyclable), sanitary, and domestic hazardous waste.
- Rule Enforcement:- District authorities implement rigid waste protocols, prohibiting open dumping, garbage burning, and public littering under local environmental laws.
- Bulk Generators:- Hotels, marriage halls, and large institutions must manage on-site waste processing or obtain local clearances for major events
2. Overview of Problems & Challenges-
Despite improving processing capabilities worldwide waste management systems face major structural hurdles:
A. Low Source Segregation:–
The Mixing Problem: Mixing organic wet waste with dry recyclables contaminates high-value materials (e.g., paper/cardboard turning to pulp),making recycling unviable and increasing sorting costs.
-
Household Compliance: Lack of consumer education and non-enforceable segregation policies lead to mixed waste collection at the doorstep.
-
B- Inadequate Processing Infrastructure:-
Capacities Lag Behind Generation: Processing facilities (composting,biomethanation, recycling plants) often lack the scale needed to handle daily intake volumes.
E-Waste & Hazardous Overload: Electronic waste is the fastest- growing waste stream globally, yet much of it ends up in the informal sector,leading to unsafe burning and heavy metal leaching.
C- Landfill Pressure & Open Dumping:-
-
Legacy Dumpsites: Worldwide, roughly 30–40% of waste remains uncollected or ends up in uncontrolled open dumpsites.
-
Environmental Threats: Uncontrolled landfills produce leachate (toxic runoff contaminating groundwater) and release large volumes of methane gas, a potent driver of climate change.
D-Financial & Logistics Bottlenecks:-
-
High Operational Costs: Up to 70–80% of municipal waste budgets are spent purely on collection and transportation rather than treatment or valorization
-
Informal Sector Integration: Millions of informal waste pickers perform crucial sorting work without formal safety equipment, fair pay, or social security
-
3- Implementation Status & Progress: Legacy Waste Remediation:-
-
Legacy waste refers to millions of tonnes of untreated municipal solid waste accumulated over decades in unscientific open landfills. Under national urban sanitation frameworks—most prominently the Swachh Bharat Mission (Urban) 2.0 and its Dumpsite Remediation Accelerator Programme (DRAP)—governments are targeting “Lakshya: Zero Dumpsites” to completely clear urban landfill mounds.
Key Remediation Metrics & Benchmark Progress
-
The National Scale: An estimated 250 million metric tonnes of legacy waste occupied roughly 15,000 acres of prime urban land across 2,400+ identified dumpsites.
-
Overall Clearance Progress: Over 60% of total identified legacy waste has been processed or is currently under active remediation across the country.
-
Fully Cleared Dumpsites: Over 1,100+ dumpsites across more than 1,000 cities have achieved 100% remediation, successfully liberating prime real estate for public parks, green covers, or municipal infrastructure.
-
Financial Backing: Central financial assistance allocated at roughly ₹550 per tonne of legacy waste processed, matching municipal and state budgetary co-funding.
