There has been a lot of impassioned debate about the – apparently – beloved green bins, and the nasty council proposing to do away with them. Petitions being signed, and by golly we’ll stop them, yessirree. There must be something wrong with me, because I always found those bins to be a proverbial pain in the posterior. Difficult to lug around, too small, never hold all your recycling anyway, so you have all sorts of junk in bags piled up on/around the bin… and on it goes. And how often would you get home in the evening to not find your bin, because the darn thing had blown away.
So for me, it would be good riddance to the green bin. Except I am in an apartment building, and we have commercial collection from a range of wheely bins already. Works for me, thanks.
Maybe one day someone will explain to me what the big deal is, and why we should keep those bins. Until then, I’ll assume it’s because of erroneous thinking – that the bin is somehow free, and so is the recycling collection. Therefore, people trying to retain the green bins are actually saying they want to keep the ‘free’ recycling service.
My view
First point, of course: recycling is not free. It is paid for out of a charge imposed on waste – the stuff that gets landfilled at the tip. It’s all there, in the council reports. The cost of recycling varies from one paragraph to another, but let’s say it is $2.4 million per annum, for the grand total of 13,000 tonnes. That cost gets recovered from the 100,000 tonnes that goes into the landfill – or a cost premium per tonne of $24. With me so far? Good. It is a good policy, in as much as the council wants to discourage waste into the landfill – so it sends the price signal: you have to pay to dump stuff. The council wants to encourage recycling, so it sends the price signal – they won’t charge you directly.
But the flaw in the model is when – if – it is successful. As waste volumes go down, the cost per tonne goes up. All good you say? Not really, because at a certain point people will stop paying, and just throw their rubbish somewhere like the side of the road: instant Greece… And this issue gets compounded if recycling volumes rise appreciably – again it’s what you want, but the cost will increase too. I’ll try to demonstrate with a couple of simple graphs.

Here is the recycling cost added on to the waste stream, for a range of waste volumes. At current volumes, it doesn’t look too bad. But as recycling volumes increase?

…starts to make the cost per tonne fairly unattractive, causing unwanted behaviours.
So the debate needs to be about the way the service will be funded, and the current choices are pretty simple – user pays (whether cross-subsidised by waste or charged directly); or rates. The council tries to apply costs directly to users where it can, meaning it would prefer to keep away from rates. And that should work for most people – you can directly control how much you have to pay, based on how much rubbish/recycling you create. After all, some couple in Kaikoura has managed to reduce their waste to 1 little bag for a whole 6 months. The counter that people usually proffer, is that poor people pay a higher proportion of their income on these things, so it isn’t fair. To that I say – there are ways to support the bottom deciles, so don’t design a whole system around the lowest common denominator. Design it for – I dunno, the top 80%, and provide those failsafe support systems as the exceptions (and make sure they are easily accessible, of course). The actual break point might vary by issue, based on more scientific analysis than I just did here, but the principle can still apply.
As to wanting to encourage recycling by making it ‘free’ – well that just proves we are all inherently lazy and selfish. We’re happy to do the morally good thing (waste less, recycle more) as long as it doesn’t inconvenience us too much. It’s sad but true, and I am as bad as the next guy. In a pure world I’d like to pay for what I create, which means I’ll pay for my recycling. I’d like to think that as volumes of recycling go up, I can benefit from processing economies of scale that mean the cost per tonne goes down.
I do understand that recycling is currently much more expensive than simply landfilling – $185 per tonne to recycle versus $82 per tonne of landfill. It also takes more time and effort to separate, but those things should not put me off doing the right thing.
I’m not hopeful…
