L29 - Water Filter

Implementing this symbol means the business/company has put in place at least one water filter available to staff for the refill of their own water bottles. Save $ 4,560.00

The growing demand for bottled water raises questions about the product’s economic and environmental costs. Water today is being sold in bottles made from polyethylene terephthalate known as (PET). The bottle has reduced in weight since the ‘80s when a one-liter bottle was 68 grams in weight compared to today’s weight of 47 grams. The total energy and resource consumption required to process and transform the 47 grams of PET material into a finished bottle, with cap and packaging, is about 3.4 megajoules of energy per bottle. This generates a total of 3 tons of carbon dioxide per ton of PET plastic. A number of other resources and emissions are produced, such as associated maintenance costs required for machinery and infrastructure, diesel fuel for the transportation from the bottle manufacturing plant to the filling station, 
Bottled water is picked up by independent wholesalers supplying shops where it is stored and refrigerated, only then, finally available for sale to the public. This second process requires another amount of energy including diesel fuel and unleaded fuel from the public driving to the shop and so on. With the first mentioned example it is possible to calculate the actual energy consumption due to the total of material processed divided by the energy and resources consumed in total by a manufacturing plant. We estimate that another similar amount of energy is used in the second stage after the production of the filled plastic bottle. We would like to show you the total energy consumption by using a close estimate of water bottle consumption by Australia's population.
If every Australian purchases one liter of bottled water per week, this will result in the following:
The material in one bottle is 47 grams of PET (1.25 liters bottle).
The energy required to process manufactured PET into the one-liter bottle is 3.4 megajoules.
The energy content in one Barrel of oil is around 6,000 megajoules.
3 Tons of Co2 emissions are entering our atmosphere to produce one ton of new PET 
Not counting the emissions generated by PET extraction plants out from the crude oil and involved laboratory and construction, maintenance, and repairs of injection molding and blow molding machinery to produce the parisons and bottle caps.
0.047 kg x 52 weeks x 21 million people                         = 51'324'000      kg of PET
51'324'000 kg of PET x 3.4 MJ  = 174,501,600 MJ           = 48'472'666.66 kW
174'501'600 MJ: 6'000 MJ =                                             = 29'083.6    barrels of oil
51'524'000 kg PET = 51'524 t of PET x 3 ton of CO2        = 154'572 tons CO2   
Using a water filter produces enormous savings
Recommended is the use of granular activated charcoal filtering cartridges.


Example: 365-day use of one water filter, 470 grams PET enclosure. Lasting 10-20 years plus internal filter replaced every 2 years Daily savings of 2x1 liter water bottles, 47 grams PET per person.
