How do you decide which type of reusable bottle you should use? The advantages and disadvantages of seven types of plastic, aluminum, stainless steel bottles will be compared to help you make an informed choice. Features related to health, performance, environmental impact, and cost will be evaluated. Environmental impact will be assessed by considering the durability of the bottles and whether they are recyclable. The resin code (type of plastic) is identifiable by the number within the triangular symbol on the bottoms of plastic bottles. Most disposable water bottles are made of plastic #1 or PET. Some people try to reduce their plastic waste by washing them out and reusing them, but bottles made out of plastic #1 are not reusable. Bottles made of plastic #1 are not durable enough to withstand use, cleaning, and reuse without losing their integrity. The compelling issue with these bottles is not whether they leach unwanted chemicals into the water, but that bacteria cannot be easily washed out of them. Long storage time on the shelf or in a warm garage or trunk does increase the likelihood of bacterial growth and may cause antimony to leach from the plastic. Contrary to urban legend, freezing bottled water does not increase the likelihood of leaching. These bottles are recyclable everywhere, and they should be recycled after a single use.
There are numerous reports that plastics. Plastic #3 (PVC) leaches phthalates which have been shown to cause developmental and reproductive damage. Plastic #6 (polystyrene) leaches styrene which can cause nervous system effects and liver damage. Polycarbonate, one type of plastic #7 (other assorted types) from which the clear, brightly colored bottles are sometimes made, has been shown to leach Bisphenol A (PBA), a hormone disruptor that mimics estrogen. Plastic #7 (polycarbonate only) is controversial. Two groups of technical experts studied it and came to differing conclusions. They agreed that BPA leaches into drinks at low levels, but one group said the levels were too low to cause any concern, and one group said that the levels were significant to human health. Polycarbonate has been banned by the Canadian government and is being re-reviewed by the USEPA. There is a new type of plastic #7 that is BPA-free; whether it leaches other substances, not currently known to be hazardous, is yet to be seen. None of these three types of plastic is widely recyclable. Plastic #7 is durable, but like most plastic, will wear more quickly if exposed to heat in the dishwasher. Bottles made from plastic #7 cost between $8 and $12.
