"In the past we manufactured non-heat resistant utensils
made from non-GMO PLA, and heat resistant utensils made from 80% non-GMO corn starch and 20% other fillers. Through recent testing, we discovered that the corn starch resin used in the production of our heat resistant utensils (a resin certified by BPI and ASTM standards) is not fully
compostable. Therefore, we have discontinued the use of the corn starch resin and have begun using an alternative resin that will meet the standards of compostability. The new resin is a mixture of 70% non-GMO PLA and 30% talc. They are also heat resistant upto 200 degrees F, and the resin is
under testing for certification under ASTM-6400 standards.
Our current non-heat resistant utensils do not have any
issues with compostability. We have also taken the opportunity to redesign our cutlery to offer a more
aesthetically pleasing option.
We will continue to offer our current utensils at a discounted
price, until they are no longer in inventory.These utensils will
take 180 days to compost in a commercial composting facility.
Home composting is not recommended as they do require a higher heat to break down, which may not occur in most
home composting systems."
I for one can say my home composter does not get hot enough to break these down. I do have and use commercial composting, but after reading some articles about it on the internet, I have come to the decision that it is better to bring my own, use bamboo chopsticks or my fingers.
