At last! It is blatantly clear that part of the cause of fly-tipping is the fact that it is so difficult to dispose of waste. We used to have a council-run rubbish/recycling centre near us, then it was closed, then re-opened under a contractor, who charges £6 per car-load. But it never seems to be open, so it's impossible to make any plans to go there.
Another problem is where to dispose of used engine oil and coolant. Both are no-nos for putting down the drain. "Find a willing local garage" is the advice. No, I want to take it to a place that will accept it, rather than try to persuade an unwilling garage, with whom I do no business.
And finally, there is a collection of old gardening powders, paint, snail repellent etc in our garage. Some of it may be old enough to qualify as historical and worthy of a museum. But in order to dispose of it, whereas I would like to just put it all in a box and take it to my local waste centre, I am supposed to itemise it by description and quantity, and then call for a Hazmat lorry to come and collect it, and pay £45 for the privilege. And they wonder why people fly-tip.
