Parcel Tape on cardboard boxes
I include cardboard boxes as browns in my compost bin at home, removing the tape where it is easily pulled off. However, some tape has always gone into the compost bin and I have removed it, in small batches, as and when I harvest finished compost from the bin. Compost C: N Ratio
This year I decided to check how much tape was actually in with the compost bin. I left a Green Johanna until all the material was composted and emptied the bin into a raised bed. The photo shows the amount of tape removed from the compost bin. The lesson would appear to be that when composting cardboard boxes all the tape should be removed before the cardboard is added to the bin.
