Fungi are the worlds recyclers so why not give them a help. As a company we have looked at our plastic use and decided to change from Juffy bags lined with plastic to cardboard made from FSC recycled materials. You can grow oyster mushrooms on them. For larger boxed ordered we pad with brown paper or if we use bubble wrap it is recycled from friends or the veg section of the co-op. We have not bought any bubble wrap for 3 years.
Unfortunately we have to use polyethylene spawn grow bag as the fungi eat anything else !!
