An organic waste digester system is provided. The system includes a heated hopper unit within the housing to receive organic waste. An agitation mechanism mixes the organic waste along with a microbe mixture to aid breakdown of the waste. Liquefied organic waste is discharged through an outlet and conveyed to a drying unit downstream of the hopper unit. The drying unit includes a microwave dryer unit.

A method for rotting an organic material includes at least partially controlling a rotting device with a control unit and feeding an organic material into a pivoted rotting chamber of the rotting device, having the organic material rotted in the rotting chamber for a rotting time, turning the rotting chamber by a chamber drive unit of the rotting device, and exhausting the rotted organic material from the rotting chamber after the rotting time. A device for rotting the organic material includes a pivoted rotting chamber for enclosing the organic material. The rotting chamber has a port and a cover associated with the port for opening and closing the port, a chamber drive unit configured to turn the rotting chamber, and a control unit connected to the chamber drive unit and configured to operate the chamber drive unit.

Some embodiments include a microalgae culturing system including a bioreactor adapted to propagate microalgae in a culture solution using in combination at least one of natural and artificial light, and at least one nutrient including at least a carbon source, where the microalgae are freely suspended in and form part of the culture solution. A microalgae feed source is coupled to the bioreactor and a first controller between a water conditioning assembly and the bioreactor. The water conditioning assembly is coupled as an input of supply water to the bioreactor, and configured to condition the supply water to a specified purity that enables substantially unhindered growth of the microalgae in the culture solution to a specified concentration, and the first controller is configured to control supply of the microalgae feed source to the bioreactor.
