Valorizing Spent Mushroom Blocks with a Custom Debagging Machine: The current mushrooms methods for removing bags in Asia are done by hand because labor is readily available and cost-effective. Such favorable labor conditions do not exist in the US, and the de-bagging step has been a major cost barrier for small speciality mushroom growers from emerging into growing entities, and has contributed to the limited accessibility and thus size of the speciality mushroom market. Removing this costly step will assuredly assist Leep in our mission of making high-quality speciality mushrooms mass-manufacturable.
