Let’s face it. Around here nothing gets thrown out until it is way past its prime. We use flats over and over again, even after they are broken. Pots, they never get thrown out. We clean them good and bleach them and reuse. But, everything must ultimately come to the end of its usability. I am sure most of us do not even think about recycling our garden pots, plastic, etc. This article from Michigan State University helps us to explore this option. I must say that I do disagree with the author on one point. They stated that some greenhouse plastic and polycarbonate may not be recyclable. In fact, I have always been taught that all greenhouse plastic and polycarbonate are 100% recyclable. Have any doubts? Check with your local company before carrying your materials in.
Go green: Which horticultural plastics can be recycled and where?
By now, greenhouse operations have gleaned the production areas of spring and early summer plant material. I have come across some operations that have deposited used and even un-used containers, flats or carrier trays in large dumpsters for recycling (Photo 1). At each operation, I have been asked about proper disposal of these horticultural plastics and the answer is easy— recycle (Photo 2)!
In other instances, I have come across garden-retail centers that accept and collect used containers from consumers (Photo 3). Regardless of where used plug or liner trays, containers or carrier trays come from, there is a possibility these horticultural plastics can be recycled.
