There is plenty of research to be done to get correct, unbiased information that is based on independent scientific evidence and testing. For several years now I have been piecing together the “single use” PLASTIC picture. During the last 2 years there has been an increasing level of “green washing”. There are companies selling products that are taking advantage of markets that are unaware of differences between certified compostable and biodegradable products and those that are not. Trying to do the right thing? Look for biodegradable or compostable certification – check the certification is not just for the water!
In broad terms there are 3 groups of “Plastics” used in bottling water:
• Petroleum based PET (probably will be with us for 10,000 or so years) –There are 5 continents of plastic floating in the oceans of our earth and the sea birds and marine animals are nesting and adapting. Only the larger mammals are ingesting them, assuming they are jelly fish and suffer the consequences.(Interesting that 80% of the plastic in the oceans comes from our landfill – bottles that are not recycled correctly)
• Petroleum based plastic with a trade marked additive which claims to oxy-degrade or oxo biodegrade (degrades over varying number of years – may be 10 years) –This type of plastic is the main concern as there seems to be no accreditation or clear evident on the success of these products to bio-degrade. The marketing of such bottles uses words like “disappear” and “green” and makes claims that appeal to people’s desire to do the right thing. In the end they are still a petroleum based product with an additive that speeds up the degradation process. The result is that small particles of plastics are introduced into our environment and to our filter feeders. Recently, there have been samples taken in open ocean where there is twice as much plastic particles as plankton and yet remains invisible to the human eye. There is no data showing how long these plastic fragments will persist in the soil and the marine environment. As with PET, the small percentage of these bottles recycled will be down-cycled into items which cannot be recycled again.
• Plant based plastic made from an environmentally polymer called PLA (polylactic acid) which is made from plant starch, a sustainable, renewable source, without the use of petroleum oil. PLA can be recycled to make more PLA bottles or composted in commercial composting facilities. Compared to PET plastic bottles, the material used to make PLA utilizes 75% less Greenhouse Gas emissions, 45% less energy and 49% less fossil fuels to manufacture.
As an example of PLA checkout EcoIslandWater bottles which are manufactured in Melbourne, tinted with Australian Green Tea, the cartons are made in Australia and packed in Australia. 100% Australian owned and operated – not by multi nationals or foreign companies. The bottle material is made from cellulosic raw materials, agricultural wastes and non-food plants.
In the near future EcoIslandWater aims to have a closed loop initiative with PLA bottles being made in Tasmania, filled with water from Cape Grim and bottles collected and returned to the factory to make more bottles. This would be a clean, productive industry for Tasmania.
Obviously a reusable bottle is the first choice, but it’s comforting to know there are smart environmental alternatives readily available here in Tasmania.
