Onsite sustainable sanitation devices for water and nutrient recycling and methods of use thereof

A method, comprising:

• macerating a solid waste input by a macerating pump to produce a slurry;
• reacting the slurry in a bioreactor to produce a gas output and a liquid substrate;
• absorbing nutrients from the liquid substrate using a biochar filter to produce a treated liquid substrate;
• and
• sterilizing the treated liquid substrate from the biochar filter to produce an amount of sterilized water.

A system, comprising:

• a grinder having a solid waste input, the grinder configured to convert the solid waste input into a slurry;
• a bioreactor in fluidic communication with the grinder, the bioreactor configured to break down the slurry into a gas output and a liquid substrate;
• a filter in fluidic communication with the bioreactor, the filter configured to produce a treated liquid substrate;
• and
• a sterilization unit in fluidic communication with the filter, the sterilization unit configured to remove a plurality of pollutants from the treated liquid substrate.
