There’s a trash-to-energy co-generation plant in West Tulsa that could probably do this. I know for a fact they’ve done evidence burns of other drugs for the state narcotics enforcement agency. The energy produced is steam that is piped directly across the street to the refinery. The heat in the burn process is extremely high and very little residual is produced. I think this company has a facility in the Houston area that will probably be a bidder.
A former Florida county sheriff where I used to live, and his Chief Deputy were arrested and prosecuted for drug trafficking.
They had the then only evidence incinerator within a hundred mikes, so every county sent their drugs, weed, etc., to them for destruction.
They would destroy a little of it for the papers and TV and then sell the rest to street dealers....................
