There has been some additional interest in bio-degradeable bags and some questions. Major questions concern how these bags degrade and the ultimate products left after degradation.
I commissioned Willow Ridge Plastics to analyze the materials we use in our bio-degradeable bags. In a nutshell, our bags bio-degrade quite well and the end result is CO2, water and humus – pretty much what is left after you grow your mushrooms. No microplastics remain.
The tests used standard protocols in a lab setting, so the actual rates of degredation you see may vary. For this reason and because the additive that allows bio-degradation is not manufactured by us, we cannot guarantee or specify a timeframe for complete degradation of these bags. Read the full report and dig into all the details.
