Cannabis biodigester

Nottinghamshire Police ("the contracting authority") wishes to procure a cannabis biodigester that renders seized cannabis plant material non-recoverable, converting it to grey water for lawful discharge under UK based environmental legislation. The machine must be able to digest "fresh" plants as well as dried leaves with "gummy" edible cannabis products optional but preferred if possible. The machine must be able to handle ~20 tonnes per year. Suppliers must size the unit to meet or exceed this throughput. Suppliers must also note if fresh cannabis plants must be shredded or could be to improve machine efficiency. The unit will be installed at a secure police site and operated by trained police staff under chain-of-custody controls - it must therefore on machine show volumes digested with tamper proof logs preferred but optional. Odour control: sealed drum/process with no persistent odour in normal operation.
