An End to the Anonymity of Trash?

Britain is quietly introducing RFID (Radio Frequency Identity) tags to rubbish bins (trash cans) in a bid to measure the individual waste of each household and charge them accordingly. Some Britons are up in arms about this, saying that households have not been informed and calling it an abuse of privacy. Is it?

The UK’s Daily Mail reports that some bins, provided by local councils for households to dispose of their trash, contain coin-sized devices that monitor how much non-recyclable waste the owner throws out:

With the bugging technology, the electronic chips are carefully hidden under the moulded front ’lip’ of wheelie bins used by householders for non-recyclable waste. As the bin is raised by the mechanical hoister at the back of the truck, the chip passes across an antenna fitted to the lifting mechanism. That enables the antenna to ’read’ a serial number assigned to each property in the street.

A computer inside the truck weighs the bin as it is raised, subtracts the weight of the bin itself and records the weight of the contents on an electronic data card.

When the truck returns to the depot, all the information collected on the round is transmitted to a hand-held device and downloaded on to the council’s centralised computer. Each household can be billed for the amount of waste collected - even though they have already paid for the services through their council tax.

According to The Mail two German companies manufacture the bins and sensors, Sulo and RFID specialist Deister Electronic.

As with all such things, the story reflects local fears, obsessions and behaviour. First off, drinking: The Mail quotes a local council chairman saying he believed the chips "were simply to ensure bins could be returned to the right addresses if they got mixed up or drunks rolled them off". Second, avoiding paying: The opposition Conservative party warns that "people will simply start dumping bags in their neighbours’ gardens or at the end of the street to avoid paying". And then there’s the whole castle thing: a council spokesman in Wiltshire says the chips were "to sort out disputes between householders about whose wheelie bin is whose. If there are any arguments we can just send out an officer to scan the chip and settle the argument." Oh, and then there’s the whole WWII hang-up: The headline at The Evening Standard’s This is London website is "Germans plant bugs in our wheelie bins".

Is this something to be worried about? Well, the government, and local councils, haven’t been very smart about installing these tags before explaining their use to the public. But that’s not unusual: A council in Australia did the same thing a few weeks back. What I think is most interesting about this is that coverage of the subject in both countries lacks depth, pandering to the fears of its readers (The Mail may not know better, but The Press Association and The Independent should.) Even basic research would show that this sort of thing is not new, is widely used elsewhere, and has a name: Pay-by-weight.

It seems the same technology is already in use in Ireland and has, according to the company involved, reduced the amount of trash put out for collection by 40%. (There may have been some privacy uproar, but I can’t find any obvious evidence of any.) In Canada the program has been in place since 1994, and as of 1999 more than 1.5 million transponders have been deployed throughout the world, including the U.S., although there have been problems with the technology (this being RFID an’ all.)

That said, just because it’s being used elsewhere doesn’t necessarily make it a good thing. Trash is as much a privacy issue as anything linked to personal property, and the angry response to the news is related to an individual’s desire to keep what they throw out a secret (however illogical this is, given you’re putting it in an unlocked plastic bin in the street for hours, if not days, before it’s picked up.) Further research into what these RFID chips are capable of isn’t particularly reassuring: The SULO device for example (PDF file), can measure exact weight, when the bin is emptied, can report any damage to the bin, and, if linked to other equipment, could also locate where the bin was emptied. Nothing too sinister about this, but it increases the possibility, at least in theory, that an individual’s trash is no longer as anonymous as it was.

Bottom line? I don’t think this is likely, and given the technology has been in active service for more than a decade. But who knows where the technology may go? This is more a story about how RFID -- although it’s not really identified in the story as such -- scares people when they hear about it because instinctively they recognise its power. No one would disagree with the goal -- reducing the amount of non-recyclable waste -- but, as with all technologies, Pay by weight has to be handled carefully, its usage and goals explained, and clear and transparent limits to its usage imposed.

You might hope that "no one would disagree with the goal", but there's a pretty lumpen mass out there who have to be dragged kicking and screaming to face reality. (See http://www.anenglishmanscastle.com/archives/003091.html and its comments for a slap-in-the-face example. I'm there in the comments, stunned by the Luddism).

Actually, this does have the potential - just - to be another GM (food or crops), where the potential benefits are big but people just distrust the technology.

Oh, one last thing: I thought once you threw stuff out in the bin it was legally no longer "yours". Hence reporters can go through it.. or am I misremembering that?
