Brazil recycles more of its aluminium drink cans than almost any other country in the world, and the achievement is worth sitting with because it was produced by a mechanism the rest of the world’s recycling policy has not generally managed to arrange. The country did it with collectors rather than kerbside, with prices rather than targets, and with a national container value that turned a discarded can into money the day it was dropped. That is the machine, and its maintenance is now the policy question.
The rate itself is the industry’s own measurement, and it deserves the attribution. The Brazilian aluminium association’s figures have placed the country’s aluminium can recycling rate above nine in ten for the better part of two decades, sustained at a level the comparable rates in much richer recycling economies have not reached, and the consistency across commodity cycles is the finding. Most recycling rates move with the price; Brazil’s has held because the system’s collection layer is priced at the can rather than the programme, which is the structural difference and not a policy detail. The industry’s own association is the source for the rate it publishes, and a measurement that has been produced for that long is measurement rather than promotion.
The mechanism’s four components are worth naming because they are what makes it work and what makes it unusual. The first is a collector network that reaches the material, which in Brazil is a national population of catadores buying and gathering cans door to door, from venues and from the trade’s aggregation points. The second is a price at the point of collection, set by the aluminium value the can contains, which converts a discarded can into immediate money for the person who hands it over. The third is an aggregation system of intermediaries and yards that turns small flows into the mill-sized loads the re-melters buy. The fourth is a domestic re-melting industry that buys the material, because a recycling rate is an industry’s feed purchase and it stops the day the purchase stops. The four together are the machine, and their interesting property is that none of them is a government programme.
The legal framework that surrounds it is real and is worth describing separately from the mechanism, because the country has also built the formal side. The National Solid Waste Policy of 2010 and the 2020 decree that created a mandatory reverse logistics system for e-waste with collection and recycling targets of 17 and 30 per cent of average annual sales are the country’s formal system, and the Monitor sets Brazil’s 2022 e-waste generation at about 2.4 billion kilograms, the largest in South America, with a sub-regional documented collection of 230 million kilograms in a 4.4 billion kilogram stream. The can recycling rate and the e-waste rate are the same country’s two extremes of performance, and the comparison between them is the policy lesson: the can rate was achieved with a price mechanism that paid the collector, and the e-waste rate is being attempted with an obligation mechanism that has not yet paid him.
Why now is a question of the can’s own economics changing under the machine, because the aluminium price the mechanism runs on is an export-linked price in a country whose currency moves. The collection rate has survived commodity cycles before, and the Monitor’s global figures describe what it survives them against: 91 billion US dollars of metal value in 2022’s e-waste with documented management capturing 28 billion, and 3.9 billion kilograms of aluminium in that stream worldwide. A nine-in-ten can rate in that market is a national asset rather than a programme outcome, and its continuation is decided by the collection price the trade continues to pay rather than by any policy instrument the country could deploy.
What should happen is the protection of the mechanism rather than its replacement, which is the unglamorous form of policy maintenance. The collector network’s livelihood depends on the payout the aggregation layer offers, and the policy measures that would damage it are the ones that make collection less attractive than it has to be: duties, licensing costs, or substituted state collection systems that compete on price with the trade that already does the work. The e-waste decree’s reverse logistics could borrow the machine’s pricing mechanism rather than trying to replace it, which is the transferable lesson of the Brazilian case and the most valuable thing about it, and the country’s catadores are the workforce both systems would use.
For traders, Brazil’s can market is the one aluminium stream whose collection rate is essentially total, and its material is the grade the international market knows it can get. The Brazilian aluminium association holds the can recycling series the mechanism is measured by, the Global E-waste Monitor 2024 holds the country’s other materials figures, and platforms such as scrap.trade carry the trade the aggregation layer produces in its documented form.
Brazil recycles almost all its drink cans because it pays the person who hands them in, on the day, in cash equivalent, for a material whose value the collector can calculate. The machine is more durable than any target written next to it, and the policy’s job is to not break it while the rest of the system catches up to the standard it has already set. Nothing about the machine requires fixing in any ordinary sense; the requirement is a price at the collector, a buyer at the mill and a policy that understands which of the three it controls.
