Different solutions work for different levels of housing density and different places for sending recyclate to. That was pretty much the only conclusion of case studies of 92 boroughs around the country trying to improve recycling rates and diversion from landfill, except for one really important finding: rubbish collection is pretty much the only council service that everyone gets. Which means everyone has an opinion on it, so as soon as any change is made, you need to at least double the number of council staff who know about waste and can answer phone calls on the subject, for at least six months. Or you end up with loads of hacked-off locals muttering "what do I pay my council tax for anyway?" and lack of buy-in as people start rumours and ends up with people not doing what is needed for the system to work.
I have problems at the moment with 5 adults, kids and one small bin. Given we recycle everything we can, and loads can go in recycling sacks, this wasn't a problem until the local foxes got even braver (as the chicken shop started composting their waste so the foxes didn't get it!), so no matter how well the dog food cans are washed, even in a dishwasher, the foxes rip the bags open...
We're about to get bins for recycling instead, which will be interesting as apparently they hold as much as 5 bags, but we routinely produce 5 bags of recycling a week, often more. And will have the dog food tins in them.
Thing is, since the council started charging for all bulky waste collection, there is an epic fly-tipping problem. Loads of skint people round here can't afford £20 to have a broken pushchair/soggy mattress removed, and it's a 45 min drive to the tip even if you have a car. So lots of justification that 'it's not fly-tipping, I'm just adding to the piles on the main road that get collected every night' or just "what else can I do?"
Education is the only way - the council newspaper has articles about successful prosecution of fly-tippers but the fines are so low that I expect they encourage rather than discourage!
SirChenjin The amount of waste packaging in the supply chain as a whole has hugely reduced over the years. The amount that's left for the consumer has increased - but then if people want to buy the guaranteed clean/unsquashed products in packets or boxes, like corn on the cob or strawberries (and believe me, that's what they actually do in practice, no matter what they say in surveys), and added packaging round the final item means huge reductions in food waste as well as much-reduced needs for thick cardboard or extra pallets during transport, then that's a good thing on the whole except for the councils who have to pay for the disposal.
Some German regions pay the supermarkets to run the deposit glass/can scheme - it certainly doesnt make money for the supermarkets - and the bottles and cans are usually recycled, not reused.
