Encourage customers to bring their own reusable food containers for takeouts and leftovers.
There is a lot of confusion over items labeled as biodegreadable or compostable.
Biodegradable items can be broken down by microorganisms over time. It does not mean that the end product is not harmful or that it won’t take a long time to degrade.
Compostable items are equally not straightforward. They are supposed to produce no toxic residue. Many products are only compostable in an industrial composting facility plant with the right temperature and conditions.
Some products are labeled Biodegradable Products Institute (BPI) certified. That means the product has met American Society for Testing and Materials (ASTM) standards in a lab, and verified by a third party.
Compost Manufacturing Alliance (CMA) conducts field tests every year to certify products for regional facilities. Different composting facilities have their own way of composting in terms of temperature and pH, so they can accept different non-food waste. Their testing has recently included PFAS.
Newer corn-based plastic, PLA (Polylactic Acid) is certified compostable in an industrial facility. It is created through the fermentation of cornstarch, sugarcane, or sugarbeets.
While we do have compost collection in the Chicago area, much of it is geared toward food waste.
Home or naturally compostable coating with PHA (Polyhydroxyalkanoates are produced in nature by bacterial fermentation of sugar or lipids) and PHB (polyhydroxybutyrate) is being researched and is expected to be available in the US in the near future. But this news has been announced years ago, so don’t hold your breath.
It’s best to use reusable non-plastic foodware whenever possible, and compost your food waste.
