Question for AC work out in the field

Hello,
Ag Field tech here. Trying to figure out a cost effective solution that also meets all the regulations to a issue. So I carry a RECOVERY only machine in the truck, discharge a system into the recovery bottle. Now what do I do with the R134a? From everything I've read for mobile AC systems the refrigerant must be recycled before it can be used again. I know there are exceptions for stationary systems and if your doing the work for your self. Can I use a shop Recovery/recycle...
