Empty?
editThe article says that the machines accept "used (empty)" cans. I can tell you from personal experience that a certain Envipco machine once accepted a full can. Granted, that was over 30 years ago; perhaps they've upgraded their machines since. 209.179.122.89 (talk) 14:15, 23 March 2013 (UTC)
Merger proposal
editWe have two articles Reverse Vending Machine and Reverse vending machine which are about the same thing. We only need one of them.— Rod talk 09:29, 6 November 2021 (UTC)
- Support. Also, the proposed destination is the older article and has the correct capitalisation. Narky Blert (talk) 13:59, 13 November 2021 (UTC)
- Support - duplicate topic. --JackFromWisconsin (talk | contribs) 21:13, 18 November 2021 (UTC)
- Done, debate was unnecessary. Abductive (reasoning) 07:22, 30 November 2021 (UTC)
Note about merge
editIt looks like a number of users contributed to the now-merged Reverse Vending Machine, then transferred their work into this article. If anybody is interested in looking into the attributions, they should examine the history of both pages. Abductive (reasoning) 07:25, 30 November 2021 (UTC)
Unclear language with some technobabble
editIn the Operation section you write that "The UPC system is different from the previous methods RVMs used which analyzed the shape and form ... substituting a barcode". A UPC is a barcode. The terms Barcode or GTIN are more inclusive. Machines still analyze the shape afterwards and don't accept a severely dented bottle or a wrong label.
I would say that: the item is scanned by a barcode scanner to read a GTIN printed on the label (not "within"). Then the shape of the container is usually compared against the system's database for the specific item code. If the dimensions of the container are not within some tolerance, it is ejected from the machine.
The Mechanics section is wordy but doesn't tell much about how the machine works to efficiently read a 3D object and identify glass or metal. What kind of camera it uses, which I came to find out. It partially duplicates the Operation section. The last sentences are particularly vague: "hardware that entails an implanted sensor that works hand in hand".
Reusable glass bottles are returned to the bottling company intact placed in crates by a technician. Crushed bottles are not sent to a bottling company but to a plastics recycler. -- J7n (talk) 05:05, 7 July 2025 (UTC)
Tomra has at least three patents that describe the validation process: the optical system, detection of the material, foreign stickers and sensing of the the container's entry into the crusher. They are intentionally very long texts. EP3440641A1, US20180232745A1, US9189911. -- J7n (talk) 09:24, 14 July 2025 (UTC)
