Volta Hits the One-Month Mark With 2,500 Reverse-Vending Machines and a Promise of 3,000 — SDR Portugal Cuts the 2026 Collection Target From 70% to 40% and Holds Back the First Numbers Until the System 'Stabilises'

Portugal's national deposit-return scheme Volta reached one month of live operation on Friday 9 May 2026, four weeks after the 10 April launch. The operating company SDR Portugal says the network now sits at roughly 2,500 reverse-vending machines distributed across supermarkets and other retail points nationwide, and is on track to hit 3,000 machines in the coming weeks as the last batches finish installation and technical testing.

The collection target was quietly cut from 70% to 40%

The most consequential update in the one-month review is not the machine count but the revised 2026 collection target. SDR Portugal has reduced the headline obligation for this year from 70% to 40%, justified as proportional to the system's mid-year launch and the ongoing transition phase. The 70% figure was the reference originally written into the regulatory framework as a steady-state expectation; carrying it through 2026 was never realistic once the launch slipped from January to April.

The rebased 40% target is what the operator now has to deliver against — and it is the number that future enforcement, if any, will be benchmarked against in the 2027 review.

The 120-day transition runs to 9 August

Volta is operating inside a 120-day transition window that ends on 9 August 2026. During this period, both labelled and unlabelled packaging coexist on supermarket shelves, as existing inventory of soft-drink bottles, water bottles, beer cans and other in-scope containers is gradually replaced with versions carrying the Volta deposit mark. Consumers can return only the labelled containers for the 10-cent refund; unlabelled stock continues to be handled through the traditional kerbside recycling system.

The transition design is also why SDR Portugal has so far refused to publish any collection numbers. "Quantitative announcement of results will be made at a more mature phase, when the system is fully stabilised," the operator told media on Friday. The position is defensible on technical grounds — the denominator (in-scope packaging actually placed on the market with the Volta label) is itself moving as the inventory rolls over — but it leaves the public, and the regulator, without an independent read on whether the 40% target is in reach.

Retailer experience: 5,000 training hours at Auchan

The retail channel that carries the operational load reports manageable friction so far. Auchan Retail Portugal's sustainability director said store teams report "operational adaptation needs, ongoing consumer education, and technical process refinement, but no critical situations." Auchan invested 5,000 employee training hours in the run-up to launch and during the first month, focused on machine operation, error-handling at the point of return, and floor staff fielding consumer questions about which containers qualify and which do not.

The early consumer-experience pinch points are familiar from other European deposit systems: bottles crushed flat or with damaged labels are rejected by the optical readers, and queues build at peak Saturday-morning shopping windows in stores where only one or two machines are installed. Both are solvable problems — additional machines, better signage, calmer cap-on / label-intact instructions — but they shape the public's first impression of whether the system works.

What this means for residents

For households living in Portugal, the practical advice is unchanged from launch: look for the Volta logo on bottles and cans, return labelled containers in their original shape (not crushed), and expect the 10-cent refund either as cash or as a supermarket voucher depending on the store. For unlabelled packaging — and there is still plenty of it on shelves until August — the kerbside amarelo bin remains the right destination.

The next milestone is the end of the transition window on 9 August, after which all in-scope packaging on sale should be Volta-labelled. By that point SDR Portugal should also be ready to release the first independent collection figures — and the gap between the 40% target and the actual print will be the first real test of whether the scheme is on track.
