Plastic bottles and metal are sought by people so it goes in a separate bin. I have also taken the habit of doing a compost and I usually bring back to France my used batteries so that they will be properly recycled and don't "accidentally" end up in the Mekong. But when it come to glass bottles, nobody seem interested in getting this stuff. How do you dispose of your bottles of wine? Do you have advices on recycling in Vientiane and Laos?
