A process for fermenting and recycling food waste that is fully enclosed, eliminating noxious odors, and therefore installable in a wide variety of urban settings at scale. Generally the steps of the process include intake, shredding and grinding, inoculation and acceleration, heterolactic fermentation, separation of solids and liquids, drying and distillation, and post-processing of liquid and solid byproducts. The result of the process includes useful goods such as nutrient-rich soil fertilizer, household cleaning agent, energy in the form of current or hydrogen, and treated water. The process is energy efficient and self-contained, resulting in the processing of food waste within 7 days, thus dramatically reducing the time of traditional fermentation processes to produce desired byproducts.

Disclosed is a method for reducing methane emission from slurry produced in a livestock farm. The method comprising the steps of guiding unheated slurry from the livestock farm to a slurry heat exchanger, raising the temperature of the unheated slurry in the slurry heat exchanger to at least 65# Celsius, guiding the at least 65# Celsius hot slurry to an intermediate slurry tank, raising the temperature of the heated slurry to at least 75# Celsius in the intermediate slurry tank, guiding the at least 75# Celsius hot slurry through the slurry heat exchanger to exchange heat with the unheated slurry to raise the temperature of the unheated slurry to the at least 65# Celsius and to cool the at least 75# Celsius hot slurry to at least below 40# Celsius, and guiding the at least below 40# Celsius cold slurry to a slurry reservoir. Furthermore, a slurry treatment plant for reducing methane emission from slurry is disclosed.

The present invention relates to a novel composter device. The device is designed to recycle organic waste for easy and convenient disposal. The device comprises a means for grinding organic waste, such as food wastes, yard trimmings, lumber, etc. and a biodegradable bag for collecting the ground organic waste. The device further comprises a button that activates the grinding function and a second button that activates a self-washing function. The device can be sized to handle large or small quantities of waste, depending on the application and setting the device is used in. Accordingly, there may be several versions of the device available to accommodate households, restaurants, schools, farms, ranches, maintenance workers, etc.
