BPA-free and fully recyclable plastic (recycling code # 1). In the USA people throw away more than 40 million plastic water bottles a year, which takes about 55,000 barrels of oil to make and puts 10,000 tons of C02 into the atmosphere every day. One million bottles full of water are transported around each week using up fossil fuels that add to greenhouses gases that cause climate change.
