You could start something up ladies in your area if its not there already
I remember talking to waste disposal agancy about cloth nappies 2 years ago and they were like "oh what a ggod idea" i was
that the people who dispose of so many nappies wer not already considering a huge campaign.
why not try contacting some organisations. Manchester doesnt have an incentive scheme and tbh it doesnt bother me i think offering money/discounts isnt the answer we need to share more info. So if you do contact people stay away from incentive scheme discussions and sell it to them as them saving money int he long run on disposal costs
I spoke to councils,environmental agancies,local environmetal groups (some wren't interested)
waste disposal agencies ect. you might make a difference in your area
