I still don't understand the logic of making it very difficult and expensive
to hand in supposedly dangerous substances.
This just encourages people to fly tip, and then the council has to send
someone out to clear it up anyway.

The logic is council's saving money

Dumped on farmland = not their problem.

West Norfolk are doing their best to avoid accepting waste of any kind
- result - flytipping, and when close to the borders using
neighbouring council's tips.
