Does anyone have any information on what type of byproducts BHO production produces and how those wastes are disposed of properly. I assume aside from the obvious butane canisters that will require proper disposal there are also buds that are contaminated in some way. I'm not finding information on this very easily. I'm also not very educated on EPA related regulations within the industry, I'm particularly interested in how different the state hazardous waste regulations are from the Federal. I'm assuming federally it would need to be classified as narcotic so how have growers and producers get around that?
