2.
We avoid adding treated grass clippings or plant materials to our compost pile because degradability and toxicity varies considerably among chemicals.
3.
The foam has achieved a 97 % degradability rating and is currently marketed by Orchidee International under the brand name " BluFoam ".
4.
In most studies, plastic items accounted for much of the debris, sometimes as much as 90 % or more of the total, owing to their ubiquitous use and poor degradability.
5.
One is to modify the carbon chain of polyethylene with an additive to improve its degradability and then its biodegradability; the other is to make a film with similar properties to polyethylene from a biodegradable substance such as starch.
6.
There is an American Standard ( ASTM D6954 ) and a British Standard ( BS8472 ) which specifies procedures to test degradability, biodegradability, and non-toxicity, and with which a properly designed and manufactured OXO product complies.
7.
Degradability studies conducted by Erhan and Bagby concluded that the pigment carrier in 100-percent soy ink degrades almost twice as completely as ink made from soy oil and petroleum resins, and more than four times as completely as standard petroleum inks.
8.
Presently it appears that degradability is not well defined with some international standard ( and more importantly, there's no clear " logical " dividing line either ), so exactly where the line is drawn is important . talk ) 14 : 18, 30 March 2012 ( UTC)
