Most current utensils on the market made from corn starch are NOT compostable. Current technology does not allow for manufacturing corn starch utensils without adding some plastic fillers. These are normally priced cheaper and do not meet compostability standards. Please be aware that these corn starch utensils are not compostable or biodegradable.
These utensils will take 120+ days to compost in a commercial composting facility. Home composting is not recommended and it may take 1-2 yrs to compost in a home composting system.
