In Canada and USA there is a movement to recycle and clean-up our trash. This has still not permeated the Asian mind....but is slowly resonating.
I know some bule in Bali (uses my pub) was involved in a plastics-recycling program but not sure of his success as I'm 'on the wagon' and don't visit the pub much.
We recycle at our villa (2 separate bins) but I see the garbage hauler throws both bins to his helper on the truck and it all goes into the same location. I then see the helper sifts thro' looking for anything of value....but I doubt if recycling is on his mind.
The N. American system has a monetary attachment and recycling has value.
'Dumpster divers' are well known in Vancouver...we encourage them by separating cans, bottles, batteries, cardboard, tyres etc., prior to the municipality garbage collections....which they return to recycling depots and get paid cash.
