Importance: Normal

Hi,

Thanks for forwarding this, Andy. When I spoke with Billy Tosheff very briefly about the process they use, he spoke about doing most of their processing and extraction outside. I know the facility they are considering has a large outdoor covered space. I’m sure we will have more questions during and after our meeting. If we need to schedule a second follow-up meeting, we can always do that. If you need me to ask him more questions before our meeting next week, I can do that too.

Gerald here is what I can find in 10 mins. These are only initial concerns for you, more research would be needed to give this subject a fair treatment.

1. Checking the application with Alice we think they are trying to process CDB-rich cannabis in to essential oil. If that is NOT what they are doing, then the below should be reviewed.
2. CBD is not illegal. However, most sources claim it’s not practical to ensure full removal of THC from this process. About 3%-5% of the final product will likely be THC, and therefore, the product produced will likely still be considered federally illegal.
3. One process that can accomplish CBD production takes Cold Ethanol and mixes it with the plant material to separate the CDB. The process is highly flammable from start to finish. After ethanol treatment the pulp is put through a sieve and filter, then you steam bath the material (similar to what a coffee maker does). Then you will cook the resulting material, such as in a water distiller. Most of the ethanol can be recovered in this way and reused, but the resulting product will be ethanol laden essential oil. You then allow the ethanol to volatize from this essential oil into the atmosphere, and test the final product to see if it’s flammable. If it is, you keep cooking, if it’s not you are done.
4. Every step above will produce a liquid waste stream unless equipment such as evaporators are put in place, and even then I’m not sure how you would avoid putting something down a drain. For example, if an ethanol/cannabis mixture batch in step 1 gets contaminated and can’t be used, it will need to go down the drain, be evaporated, or be hauled away.
