Plastic BSF? Home Forums BioSandFilter Forum Plastic BSF? Guest Participant 5th August 2013 at 4:03 pm #855 Hi Guys, I am working on a project which is making plastic BSF. Does any one know where to source used food grade barrels? We are having trouble finding a cost effective way of sourcing these barrels.
