Letter to the Editor - Biodegradability
You are correct
Dear Sir. You are correct I had not heard or seen this website before although I have seen the presentations by many of your members. –thank you for pointing it out.
I must admit to be being overwhelmed by the amount of statements as to evidence for the true “biodegradability” of these products in so many environments . If such multiple statements are in fact absolutely true then it appears that these products really do offer the best answer to many of the problems of plastics disposal .
As a technologist, I still would really like to see the scientific evidence supporting the variety of claims made so that I plus others who may be interested, can really evaluate the information and judge for themselves the validity of the statements. I think it would be in all of our interests to see this information publicly available on the website (as opposed to having to buy a book to find it). Is this possible?
Also, as I have already stated, I am not confined in my thinking to these products meeting present day biodegradation standards. It is true that if a claim of biodegradation is made I do like to see evidence to support this claim and this goes beyond showing microbes attacking the surface since this just tells me that some component can be attacked. I would, therefore really like to see definitive evidence that the products eventually do completely mineralize to carbon dioxide and water – with some understanding of how long it takes in a particular environments being claimed. That is all I have been asking for.
Could you also inform me how many plastics does this technology apply to? I see claims for PE, PP and Polystyrene are there others?
Thank you again in advance for providing the substantive supporting information.
