Polylactic acid (PLA) is a type of plastic that is made from plant-based materials, such as cornstarch or potato starch.
PLA is often used to make compostable packaging, such as cups, containers, and utensils.
If you add PLA compostable plastics to a home composting bin, they should break down over time and release nutrients into the soil that can be beneficial for plants.
However, it is important to follow the instructions on the packaging and to make sure that the composting conditions in your home composting bin are suitable for the material.
PLA plastics may not break down properly if the compost is too dry or if it is not turned regularly.
It is also important to note that not all PLA plastics are created equal.
Some types of PLA plastics may break down more quickly than others, and some may not break down at all in a home composting bin.
If you are not sure whether a particular type of PLA plastic is suitable for your home composting bin, leave them out.
