Unfortunately, yes there are plastics in our organic soils.  The reason for the plastics is largely due to what we (as households) are throwing into our compost bins.  The main supply of the plastics are fruit tags and compostable bags.  In order to be 100% plastic-free we need to be aware of what we are putting into the compost bin. Next time you toss your banana in the green bin, remember to remove the sticker first!
