[GreenYes] Re: PLA-Compostability

[Anne Peters <annep@no.address>]

A researcher at Michigan State University did composting of PLA plastics 
last year of real products in real compost piles.  They placed PLA trays 
and bottles tested in compost @ 140ÂF Â 10ÂF for 30 days and achieved 
complete reduction.  I'm on the road & don't have the citation - it's in 
my paper files. If you can't find it by searching the MSU website (an 
asst. prof there I believe; he might have done a lit review as part of 
his research, too) email me after 3/1 and I'll dig the citation out.
