Closing Dhaka's Collection and Landfill Gap: A Department of Environment Mandate for Solid-Waste

Diagnosis

Dhaka generates roughly 6,500 tonnes of waste per day, and the city runs a persistent collection and landfill gap (per the curated note). That gap is not an abstraction. Waste that is not collected ends up in canals, drains, roadside heaps, and open burning, which means each unaddressed tonne returns as urban flooding, public-health load, and air pollution. The structural nature of the problem matters now because the daily generation figure is large and recurring: every day the system clears less than it produces, the backlog and its downstream costs compound. There is no current quantified state value on record for the gap itself, which is itself a finding: the system is being managed without a measured baseline for how much waste is collected versus generated, and without a baseline you cannot set a target or hold anyone accountable. The lead responsible body is the Department of Environment (DoE), with the Forest Department as a supporting body.

Recommended actions

1. Establish a measured collection-versus-generation baseline. Owner: DoE. Mechanism: a standing measurement protocol requiring weighbridge records and tonnage logs at every transfer station and disposal site serving Dhaka, reported on a fixed schedule to DoE. Observable signal: a published monthly figure for tonnes collected against the roughly 6,500 tonnes per day generated, so the gap is finally a number, not an impression.
2. Mandate source segregation at the household and commercial level. Owner: DoE, coordinating with city corporations as the on-the-ground collection authorities. Mechanism: a DoE circular setting a wet-versus-dry separation standard, phased by ward, tied to the collection contracts. Observable signal: the share of segregated waste arriving at transfer stations rises, and the volume of mixed waste sent to disposal falls.
3. Convert open dumping to engineered, contained disposal. Owner: DoE as the environmental regulator, with the Forest Department supporting buffer and boundary greening of disposal sites. Mechanism: an enforced disposal-site standard (leachate containment, daily cover, restricted open burning) written into the operating permit for each site. Observable signal: open-burning incidents and uncontained leachate fall at permitted sites, verified by DoE inspection.
4. Tie collection-service payment to verified delivery. Owner: DoE, with the relevant budget line for waste-collection contracts. Mechanism: performance-linked contracting where operators are paid against weighbridge-verified tonnage delivered to engineered sites, not against headcount or fleet size. Observable signal: the collection figure converges toward the generation figure over successive reporting periods.
5. Stand up the missing data collector. Owner: DoE. Mechanism: a formal data line that ingests the weighbridge and inspection records into a single registry. Observable signal: the data-needs gap closes and the indicator moves from unmeasured to tracked.

Sequencing (first 12 months)

Do the measurement first. Actions 1 and 5 are the unlock: until DoE can state, monthly, how many tonnes are collected against the roughly 6,500 tonnes per day generated, every other action is unverifiable. With a baseline in hand, the segregation circular (action 2) and the disposal-site standard (action 3) become enforceable because compliance can be checked against tonnage and inspection records. Performance-linked payment (action 4) comes last in the year because it depends on the weighbridge data from action 1 being trusted.

Risks and constraints

The binding constraint is institutional, not technical. DoE is the environmental regulator, but day-to-day collection sits with city authorities, so DoE's leverage runs through standards, permits, and circulars rather than direct operation, and enforcement can stall where coordination is weak. Fiscally, engineered disposal and weighbridge instrumentation carry upfront cost against a recurring operating budget, so the disposal-site standard must be phased to what the budget line can sustain. Politically, source segregation asks behavior change from millions of households, which fails without sustained, ward-level communication.

Bottom line

Dhaka's roughly 6,500 tonnes per day overwhelm a system with no measured collection-versus-landfill gap, so the first job is to make the gap a number DoE reports every month. Once measured, segregation, engineered disposal, and delivery-linked payment can be enforced against that number instead of against impressions.
