Today's funeral practices are unsustainable, toxic, and polluting. Both cremation and the manufacture and transport of caskets, grave liners, and headstones emit greenhouse gas emissions into the atmosphere. In fact, the very last thing that most of us will do on this earth is poison it. As a response, a system and method called recomposition that gently and naturally returns humans to the earth after death.

The present application provides a reactor with an inclined bottom gas-inlet for aerobic fermentation. A fermenter is provided with a circular inner tank, end covers and a jacket. An airtight fermentation space is formed in the fermenter by the inner tank, an upper end cover and a lower end cover. A feed opening and an exhaust outlet are arranged at an upper part of the fermenter, and a discharge opening is arranged at a lower part of the lower end cover of the fermenter. An energy-saving stirrer is mounted in the fermenter. A plurality of air chambers are arranged at an external wall at the bottom of the inner tank of the fermenter and are within the jacket. A plurality of aeration nozzles are defined on an inner side of each air chamber, and the aeration nozzles are disposed next to the inner tank.

A rotary composter includes a rotatable composting drum, a motor for rotating the drum, an aeration system for supplying air to the drum and an open-loop computerized controller for controlling one or both of the motor and the aeration system based on animal growth data. The rotary composter may also have a wireless nitrogen gas sensor for sensing an amount of nitrogen gas in the drum and a load cell for measuring a mass inside the drum to enable the controller to further control one or both of the motor and the aeration system based on signals from the nitrogen gas sensor and the load cell.
