The following comment I found interesting.
The Orkney Climb Club had a mass climb and clean up in 2007 and carried out 4 exped rucsacs full of old rope, pegs, crabs and tat. Within a year the belay and abseil stations were full of slings and rope again….problem not solved !
Although it would be contentious, each belay / abseil point could have stainless steel bolt lower off chains / points in suitable tangle free locations. This is the only way this issue will be reduced or reduced and safety increased.
