The Waste We Cannot Account For

Executive Summary. Bangladesh's plastic action plan begins with a warning disguised as a baseline. Urban plastic consumption rose from an estimated 3.0 kilograms per person in 2005 to 9.0 kilograms in 2020, while Dhaka reached an estimated 24.0 kilograms. The plan estimated 646 tonnes of plastic per day in collected municipal waste across Dhaka North and South. Of that flow, 48% went to landfills, 37% was recycled, 12% reached canals and rivers, and 3% was dumped in drains or unserved areas. Yet the country still lacks a recurring public material account that tracks production, imports, collection, sorting, recycling, disposal, and leakage with reconciled definitions. Targets for recycling, virgin material, single-use plastics, and waste reduction cannot be managed through occasional studies. Bangladesh needs an auditable plastic ledger, backed by producer reporting and municipal weighing, that makes missing waste visible before policy claims success.

Consumption moved faster than the system

The action plan estimates annual urban plastic consumption at 3.0 kilograms per person in 2005 and 9.0 kilograms in 2020. Dhaka's estimate was 24.0 kilograms per person in 2020. These figures are survey-based estimates, not a national administrative series. Their value is to show direction and scale, while their limitation is precisely why a permanent account is needed.

Plastic grows with income, retail packaging, convenience, and urban consumption. Its physical advantages become management liabilities after use. Light flexible packaging is cheap to move into the market and costly to recover from drains, mixed waste, and river edges. Material with little resale value has no reliable private collector even when its environmental cost is high.

The action plan's Dhaka baseline estimated 6,464 tonnes of municipal waste per day, of which 646 tonnes was plastic. It also reported that only 30% of postconsumer packaging waste was collected. Those statements describe different denominators and should not be merged into one collection rate. The first concerns plastic inside collected municipal waste. The second concerns postconsumer packaging. A material account must keep those populations separate.

That discipline sounds technical, but it decides whether a target is real. If the denominator changes as collection improves, a recycling percentage can rise or fall without the physical recovery system changing. If producers report sales by weight while cities report mixed waste by volume, the accounts cannot reconcile. If informal collectors disappear from official records, the system can undercount its most effective recovery channel.

The baseline shows where the material went

Within the Dhaka baseline's accounted plastic flow, 48% went to landfill and 37% was recycled. Another 12% reached canals and rivers, while 3% was dumped in drains or unserved areas. The shares sum to the accounted flow, but they do not prove that every item entering the city was observed.

The chart makes two policy failures visible. First, disposal still dominates recovery. Landfilled plastic has been collected, transported, and concentrated, but its material value is lost. Second, leakage is not a distant marine problem. It begins in neighbourhoods where low-value packaging bypasses collection or falls out of the chain.

The plan estimated that 24,032 to 36,047 tonnes of plastic waste per year were disposed at water-connected hot spots. The range is marked as an estimate because field observations and scaling cannot produce an exact administrative total. It should not be converted into a confident single number. What matters operationally is that the hot spots are measurable locations. Each can be assigned, revisited, and checked for recurrence.

This is where accounting and service delivery meet. A ledger should not stop at tonnes. It should record the route: who placed material on the market, which municipality or contractor collected it, which sorter received it, what fraction was rejected, where recycled resin went, and where residuals were disposed. For low-value flexible packaging, producer responsibility must fund the route that resale value alone cannot support.

Targets without accounts become slogans

The action plan set large outcomes from its baseline. It called for a 50% reduction in virgin material consumption by 2030, at least a 90% phaseout of targeted single-use plastics by 2026, an 80% recycling rate by 2030, and a 30% reduction in annual plastic waste generation by 2030.

These targets address different parts of the system. Virgin material use concerns production inputs. Single-use phaseout concerns selected products. Recycling rate concerns end-of-life recovery. Waste-generation reduction concerns the total output of discarded material. Progress in one does not guarantee progress in another. A lightweight package can reduce virgin resin while becoming less recyclable. A high recycling rate can coexist with rising total waste. A ban can shift consumption to another disposable material whose impacts are not counted.

The reporting architecture must therefore preserve each denominator. Producer declarations should use common resin and product categories. Customs data should identify relevant polymer and product flows. Municipal facilities should weigh incoming and outgoing material. Recyclers should report feedstock, output, and rejects without exposing commercially sensitive transactions. Independent audits should reconcile totals and explain gaps.

Product design belongs inside the ledger because weight alone can reward the wrong change. A lighter multilayer package may use less resin but be harder to sort and recycle. A returnable container may be heavier at first use but circulate many times. Reporting should therefore pair mass with product format, recycled content, reuse cycles where verifiable, and end-of-life route. The goal is not to create a perfect environmental score. It is to stop a reduction in one category from being presented as system-wide progress when cost moved elsewhere.

The informal sector is not a residual to be formalized out of existence. It is part of the current infrastructure. Registration, safer work, predictable purchase arrangements, and access to sorting space can improve data and welfare together. A ledger that counts only licensed firms will produce a clean table and a false system.

The strongest counterargument is that measurement can delay cleanup

The strongest objection is practical. Bangladesh does not need to know the exact mass of every wrapper before clearing drains, enforcing litter rules, improving collection, or restricting products that repeatedly appear in waterways. An elaborate ledger could become an excuse for consultants and committees while waste continues to move.

That objection is valid against sequencing measurement before all action. Visible hot spots should be cleared and serviced now. Producers can begin financing collection now. Municipal contracts can require weighing now. The action plan already identifies the direction.

But action without measurement is vulnerable to substitution and exaggeration. A city can report more collection while the unserved area remains unchanged. A producer can reduce one product and increase another. A recycling facility can count material received while rejects return to disposal. A cleanup can remove waste once while the upstream flow continues.

Procurement offers an immediate bridge. Public buyers can require suppliers to disclose packaging, take-back arrangements, and recycled content under the same categories used in the national ledger. Municipal contracts can pay for verified recovery rather than vehicle trips alone. These rules create demand for comparable records before the whole economy is covered. They also expose where reporting burdens are unrealistic, allowing the standard to improve through use rather than remain a paper design.

The answer is minimum viable accounting tied to operations. Each intervention should begin with a baseline that can be repeated using the same definition. The account can grow in coverage and precision, but its core reconciliation rule should exist from the start: material placed on the market must equal material retained in use, recovered, disposed, exported, or unexplained within an explicit uncertainty range.

What would change this conclusion

A checkable test would overturn the argument: if Bangladesh can already publish a recurring national plastic flow in which production, imports, use, collection, recycling, disposal, export, and leakage reconcile under stable definitions, then the missing account is not the binding constraint. The evidence would be the series itself, audit notes, and public explanations for revisions.

First, establish the plastic material ledger. Require standardized weight-based reporting from major producers, importers, municipalities, transfer stations, landfills, and recyclers, with explicit treatment of informal recovery. Owner: Department of Environment with customs and local government. Success signal: an annual balance publishes every major flow, its uncertainty, and an unexplained residual that declines across releases.

Second, attach producer finance to low-value material. Set fees by product design, collection cost, and demonstrated recoverability, then fund verified collection and sorting where market value is insufficient. Owner: environmental regulators and producer-responsibility organizations. Success signal: the share reaching canals, rivers, drains, and unserved areas falls below the baseline while recovery workers receive documented safer terms.

Third, turn hot spots into service tests. Assign each observed leakage point to a municipality or operator, record cleanup and collection changes, and revisit it after rain and high-use periods. Owner: city corporations and municipalities. Success signal: repeated inspections show that cleared sites remain clear because the local collection route changed, not because waste was moved out of sight.

The waste Bangladesh cannot account for is not merely the material missing from a table. It is the policy claim that cannot be tested because the table does not exist. A credible circular economy begins when every actor can see where the material went.

The ledger makes that visibility routine.
