Maize Starch: biodegradability testing of a pen

[Christophe]

Uh, were these bags given for biodegradable?

highflyaddict, according to you the earth "rises" by how many cm per year on average in the forest for example?

It is very variable obviously but very largely enough to bury synthetic objects naturally before they are biodegraded ...

Without O2 it can very well break down but it gives methane (bast the naughty!)

I'll open the pot, we'll see if it changes something

Yes quite

[Christophe]

The pot is open (it did not smell the rose at the opening: a very pungent acid smell ...) ... case to follow!

Christophe was doing Laigret without knowing it

[Christophe]

Hi hi hi, Laigret I do not know but megret (as rotten) yes!

Greg, the biodegradability must be done logically in the absence of oxygen ... underground there is little oxygen from a moment ... but I am willing to try to open the pot to see ...

.

I do not find it very logical precisely: the decomposition in nature is done on the ground and in the first centimeters, in the presence of oxygen therefore. [...]

Oh well, I did not see that !!!
Completely agree with the dolphin, it is exactly the opposite: the biodegradation of organic matter is much better in the presence of oxygen!


Regarding the bag of my friend, it is at the same point as July 2008: intact! you talk about a biodegradable thing ...

[Christophe]

Yes with O2 it works better but without O2 it SHOULD also walk otherwise it is NOT really biodegradable .... That's what I meant!

For example: under water? The dissolved O2 is much weaker than in the air ... Sell a biodegradable product if it is only in the air 1 / 2 lies ...

The pot is open ... We'll see if it changes something ...

In any case it stinks well (it starts to feel a little liquid, logical with the compost put in the water ...)! We will see if there is any effect on the ca

Strange for your buddy's bag, is it a bag "sold" as biodegradable? This is in total contradiction with Renaud's experience!

Yes it works too, but on other processes of degradation, much longer.

It is a bag provided by a motorway company with the mention: "Oxo-bio degradable" ... still a bullshit of marketers in need of greenery!

I think it is not corn starch, it does not look like it at all.

[Christophe]

Ah yes I do not know what "oxo-bio" degrabable means ...

Maybe it's biodegradable on the planet Oxo?

At a pharmacist, I had an oxo-biodegradable bag
