Various embodiments are described herein for an apparatus that implements one or methods for producing compost. The method may include receiving waste in a composting apparatus, the waste having a first moisture content; pre-treating the waste to produce pre-treated waste; storing the pre-treated waste into a storage chamber for a pretreatment time period to produce stored waste; and composting the stored waste in a compost chamber to produce a batch of output compost having a second moisture content, wherein the second moisture content is less than the first moisture content.

The present invention relates to an organic matter biodigester comprising a tank that has an organic matter inlet, a first connection arranged in an upper portion of the tank and a second connection arranged in the lower portion of the tank. Furthermore, said tank also has a biogas outlet and a lower surface configured to rest on a support surface. Furthermore, the lower portion of the tank is at a shorter distance from the support surface compared to the upper portion of the tank. Said organic matter biodigester also comprises a manual pump with a pump inlet connected in the second connection, and a pump outlet connected in the first connection of the tank. The pump is configured to recirculate the organic matter inside the tank from the second connection towards the first connection; and a porous layer arranged inside the tank.

A method of determining the volume of organic material in a composting device includes rotating a mixing paddle in a composting bin that stores the organic material; monitoring the torque from a motor that rotates the mixing paddle as the mixing paddle rotates; and determining the height of the organic material in the composting bin based on the motor torque and the angular displacement of the mixing paddle. The resulting height can be used to determine the volume of the organic material.

A tunable method and system for treating organic material to form nutrient-rich products are disclosed. Exemplary methods and systems include determining and/or selecting from where and/or when to pick up organic material for processing. Other exemplary methods and systems include providing soil amendments that can be tuned based on organic material to be treated and/or a desired product composition.
