Its a very loose term.
The word degradable can be made to whore itself on the streets in the mouth of a supermarkets PR dept.
Degradable means something which will degrade. it says nothing about how it degrades (Acid, nuclear bombs to destruct it) or what it degrades into (poisonous waste, useless slime, traffic wardens).
Bio-degradable apparantly means it will break down on its own into biological components.
Its probably a lot more complicated than that, but its still a word that you can put your own interpretation on.

Degradable basically means it will break down into smaller pieces - the smaller pieces are then left to blow around the planet for hundreds of years.
Bio-degradable items completely disappear. Tesco's are very short sighted to follow that degradable rather than bio-degradable route, leaving themselves open to attack by supermarkets who have taken the bio-degradable route (hopefully ASDA).

For what it is worth I have heard that there is a widescale LSE inquiry currently being conducted into the activities of one or more MM's for manipulating sp's to cause volatility - encouraging shorting and denigrating. They would do well to look at SEO in particular on that one.

Oblo,
As per posts on the subject many moons ago, it could be that they are using the term loosely, not knowing that it would be that important to certain SEO investors! when the supplier is revealed, we'll know for sure!

Hi Sharesure
Don't know whether you have seen my post number 18420 on page 921 to the SEO board.
If you have and are available, and we get an invitiation to meet with a couple of directors in Southampton, would you be interested in accompanying myself and tonyrelaxes on such an excursion? If you recall we all met at the AGM.
The oily one

"
Further Environmental Life Cycle Information on the Various Bag Alternatives
Production and Disposal
In reality, the majority of lightweight plastic carrier bags, including the biodegradable variants, will be sent to landfill where they will be buried under predominantly anaerobic conditions.
In the case of starch-based biodegradable lightweight plastic carrier bags, they will take a long time to decompose if they are buried under two metres or more. Under such circumstances, they will give rise to methane instead of carbon dioxide, which is 23 times more potent for global warming 10 (therefore negating the carbon neutral status of the plant-based raw material). They may not even decompose significantly if the necessary microbes are absent due to the anaerobic conditions within the landfill. It should be noted that Scotland and the UK currently uses very few such starch-based biodegradable bags.
Likewise, the plastic ( HDPE) with metal degradant additive bags have a slower rate of degradation when in a landfill rather than in the ideal conditions. In a landfill, they may take 1-5 years 11 to decompose (or even not at all due to lack of light and oxygen) [EuroCommerce, RMIT]. These kind of degradable bags are used in the UK by the Co-operative Group and Somerfield. It has been estimated that conventional HDPE bags take anywhere between 450 and 1,000 years to decompose [ MCS 2005]; thus, within a century-long timescale, they can basically be seen as inert material [ DEH].
Ethene, the monomer used to manufacture polyethene, is produced as a by-product of crude oil refining ('cracking') in the manufacture of vehicle fuels. Its production will not therefore drop. The resource argument would be that the ethene no longer wanted for polyethene bag manufacture could be used as a chemical feedstock for other uses."

Sharesure,
i do you are correct about the LSE looking into the activity of the MMs,3000000 more buys than sells yesterday SP didn't make 0.50, today just one eg SP 4-95 an AT of 77 price drops 4-93 another share they could look at is DGO

If there is a LSE inquiry , they should look at EEL.

Gary,
just reading your post. Its actually quite negative.
What it is saying is that unless we create the right conditions for bio-degradable plastic to decompose, we are no better off than with conventional plastics.
I mentioned a few weeks ago that Asda had concerns over the green-ness of Starpol, but I knew nothing of this last bit. Perhaps they did know something and are questioning what the point is unless they can provide follow up composting facilities.

Yes Alan,
It is negative with regard to bio-plastics as it is seen as an additional material due to the fact that the cracking process will still produce the same volume of PE material which will have to go to some other use. So even though the production of bio-plastics is less harmfull on a direct comparison pound-for-pound, in their framework it simply adds to the environmental burden.
IF however, fuel production were to deminish, the case for improves.
That said, the production of paper items appears to be the most damaging, but considerably more beneficial with regard to waste.

But wouldn't the released methane ignite under landfill site conditions? I've seen landfill sites used for domestic waste and there are always small fires burning, caused by the heat produced during composting.
Carbon dioxide wouldn't burn itself out - it would enter the atmosphere.

Oblo/S.T.,
Its called Biogas which is a viable alternative fuel, use by certain industries. Landfills tend to flash off the methane, hence the flames seen.

So. In essence, Starpol is a greener alternative, but only if you either have the right disposal facilities in place or it goes to one of the few landfills that produce power from the resultant methane. The oil used in current plastic packaging is a by-product of stuff we will continue to use anyway, so no gain there.
We have rapidly come to an environmental audit that says its not a lot better.
Weeks ago, this was exactly what i was caused to ask by my imaginary friend, though I belted off down the wrong track altogether.
Could it be, therefore, that the delays are not of a technical nature, or of a contractual nature, but are caused by Asda / WM realising that there super duper new green image could be tarnished if they announce Greenseal / Starpol to the world, only to find that some polytechnic dropout pops up on a news bulletin and shoots it down?
Remember though, the environment is only one thing going for the products. the reduced cost of energy on the production, the longer shelf life, more presentable packaging and better seal are all simply business choices, dictated by the bottom line.
Thoughts anyone?

What about all these engineers in the USA who have been trained to convert Greenseal , if Stanelco don't hurry up these engineers will need a refresher course as they would of forgotten what to do !!!

I have it on good (cast iron) authority that all SEO's Greenseal experts, including Rob White the main salesman, were not available today as they were all in meetings. Whilst not good for sales, could it mean that they were busy finalising something?

ASDA LAUNCHES 'OLD BAGS' CAMPAIGN
Supermarket Set To Introduce Reusable 'Bags For Life' In Stores Nationwide
ASDA confirmed today it wants to discourage customers from using free, single trip plastic carrier bags by introducing a new range of 'bags for life' in all of its 307 stores nationwide*. The new durable bags are designed for repeated use and will cost just 5p

Dont think we've seen these before (maybe the second one) - the first is interesting, but unfortunately shows some competition. SEO are mentioned near the bottom.
