poly tanks

this is a very interesting discussion on the recyclability of degraded poly tanks, and their future impact on the environment. http://thegreataustralianpolytankdebate ... results=50

I think his arguments don't hold up very well to scrutiny. Reading through many of the emails on there, he just keeps badgering people over and over again with the same questions even after they respond to his quesitons.

And when people don't answer him, or get annoyed with the constant questions he threatens them..

You know I am considering publishing my work which eventually will find its way all over Australia. Every response you make is being documented and will be out in the open for public scrutiny.

How you proceed is up to you.

I think a little more research on his own behalf would be a better way to approach the subject rather than bombarding the end retail outlets. I thought the following summed up answers to his query pretty well, but he wasn;t happy with that, just kept on asking the same questions of other people.

Quote:

Answer to your question are as follow;

Poly Tank Industry recycle plastic by re-milling process. Such recycled plastics were used in making of different products eg. Troughs, Gardens Tools, Plants containers and more.

Every material has a life that will eventually be broken-down completely if you do not attempt anything to recover it.

In relation to poly tanks, Action Tanks issue 10 Years warranty on the its product which is in-line with the industry warranty. End user must maintain the tank system (yearly) and check the tank strength on regular basis (after 10 years).

At some point, the tank will be no longer strong enough to hold the liquid due to stress factors over a long period. At that point, you will need to replace the tank. This could possibly be 25-30 years later depending on the conditions.

Bottom line is that your tank will need replacing well before the material was broken down completely. End of the life for poly tank is when the tank is no longer able to perform its function (hold water), NOT at the point when the tank was completely broken down. At the end of its life, your poly tank can still be recycled.

I hope this answer your question.

Humm... wonder if he (or anyone else) has asked the question about the "recycling" of fibreglass tanks... widely used within aquaculture... and by some aquaponics ventures both here and overseas...

Personally... I think the lifespans are probably comparable to poly products... but I'd tend to think the "poly" products stand a much better chance of being recycled... :wink:

And there are now "plastic" eating bacteria... don't know if there are any fibreglass bacteria though.

This guy sounds like someone else but the name eludes me. :scratch:

Might have to sit outside and watch my airlift pump moving water around and see If it comes to me. :mrgreen:

i thought he did have some valid points however. If the tank has degraded du to breakdown from the affects of the sun etc can it be recycled? I also think it is fair to ask the question if i am buying a water tank and the manufacturer claims it is recycelable and that is a reason i buy it. If after the life of the tank it in fact cannot be reused then is the maufacturers statement fraudulent?

bluefin

please be aware i in no way against the use of plastics from the polyolifin group. I think they are essential and amazing. I am interested in the carbon footprint of all types of water storage vessels, steel, concrete and composites.

Do you have any results, or trends bluefin???
concrete/steel/fibreglass/poly/etc

bluefin

there is an article in an eco gardening mag i get. it stated that steel was less of a drain on finite resources throughout its manufactured life. ill try to dig it out. Im not really researching it or anything im just curious. I work as a teacher at the moment but i am also a plumber and gasfitter. Ive used and installed heaps of different materials over the years.

Most poly tanks are made from "food grade" plastics these days... and have been "UV stabilised".....

I figure that doesn't mean that they're totally impervious to decades of UV exposure and will eventually degrade.. as will any other materials...

But has any actual research or lifespan been determined??

A bit OT but you teach and you're a gasfit plumber :shock:

poly will be here longer than steel

, but is cheaper than concrete
F....glass, is not my friend,
liners have 30 warranty but a spike will wreck them :roll:

but this has nothing to do with carbon footprint size,
though I guess the service life is a measure??

bluefin

ot ? I guess the tanks life would depend on its exposure to uv light. In the emails he recieved, some manufactures caimed 30 years. i agree iwith a poly tank lasting longer.
