Documented channels handled 13.8 of the 62 million tonnes of e-waste generated in 2022
A commentary on secondhand exports to Accra argues that environmental obligations stay behind when goods cross a border. The one hard figure it cites, a 22.3 percent collection rate, measures bookkeeping.

What happened
- Thousands of pieces of secondhand clothing arrive each week at Kantamanto Market in Accra, described in the commentary as one of the world's largest textile resale hubs.
- Jocelyne Landry Tsonang of the African Circular Economy Network told the symposium that products often travel without the responsibility mechanisms, eco-taxes or funding that should come with them.
- The same Accra market is cited as a circular-economy success story for the scale of its reuse and repair work, and is also left with mountains of clothing nobody will buy.

Why it matters
- constraint A target written against documented collection can be met by widening the paperwork. The 48.2 million tonnes with no recorded destination would not move on that scoreboard at all.
- exposure The step that turns a dead device into saleable copper is done by hand, often without protective equipment, so the health cost of recovery sits with the people doing the recovering.
- decision Anyone designing a take-back scheme has to choose whether the eco-fee stays with the first collection point or follows the product to wherever it stops being useful.
- contradiction On reuse volume Kantamanto is a model; on residual waste it is a disposal site.
The Global E-waste Monitor 2024 put 2022 generation at 62 million metric tonnes [7], of which 22.3 percent was officially collected and recycled through documented channels [8]. The two together put about 13.8 million tonnes on a paper trail. That leaves 48.2 million tonnes outside any register [9]. The larger figure is a residual: everything the counting system did not see, whether that material was landfilled at home, left in a drawer, or repaired and resold somewhere that issues no receipts.
The essay supplies its own caution about the straight-line version of the story. It cites the Canadian geographer Josh Lepawsky, whose 2018 book "Reassembling Rubbish" argued that electronic waste does not flow in one direction from north to south but through globalized networks where reuse, repair, material recovery and dismantling intersect [10]. A customs line is a poor place to measure that. Material can cross it more than once.
What the piece is: a first-person account of a symposium, a handful of cited books and papers, and that one statistic. The symposium, "When the Global South Inspires the Global North", ran during the 93rd Acfas congress, and the author attended it while researching organizational governance models and the shift toward a regionalized circular economy [5]. Jocelyne Landry Tsonang of the African Circular Economy Network said in her opening remarks that products often travel without the responsibility mechanisms, eco-taxes or funding that should come with them [6]. The argument turns on that claim, and the essay offers no count of schemes, fees or tonnes to size it.
The textile claim has the same shape. Large volumes of used clothing go each year to secondhand markets in Africa, Latin America and Asia, and where a shipment is largely low-quality, unsellable or hard to recycle, the receiving country inherits a waste problem it did not create [13]. The unsellable share is the quantity that would fix the size of that transfer. The commentary asserts that the environmental cost of the clothing nobody buys falls on Ghana and not on the markets that shipped it [16], and it gives no figure for either side of that ledger.
The definition the essay borrows from a 2017 Copernicus Institute of Sustainable Development analysis at Utrecht University covers operations on materials: reuse, repair, recycling and longer product lifespans [15]. Cost allocation sits outside it. Max Liboiron's 2021 book "Pollution Is Colonialism" argues that environmental harm is never spread neutrally, with some populations benefiting and others absorbing a disproportionate share of the fallout [12]. In several African cities that argument has a concrete referent. Waste pickers extract copper, aluminum and other metals from used electronic devices, frequently without adequate protective equipment, under precarious conditions and with little institutional recognition [11].
What to watch
- Whether a future Global E-waste Monitor reports destinations for the material outside documented channels, rather than only the collected share.
- Whether any exporting jurisdiction makes a producer fee payable where the product ends its life; Tsonang's complaint is that the funding does not travel.
- Whether anyone publishes the unsellable share of textile shipments arriving at Kantamanto, which is the number that would size the transfer.
