Abstract
The invention is a system and method for transforming food waste into a commercial cleaning product. The system is containable in an enclosed facility and installable in urban environments. Food waste is sorted and ground into uniformly sized particles, heated to an acceleration temperature, inoculated with an inoculant including lactic acid bacteria, which is mixed into the ground waste. The waste then undergoes sedentary fermentation for times as short as 24 hours or less. The fermented waste is separated into liquids and solids, and liquids are further separated into at least one distillation stream. Solids are dried to obtain a second distillation stream.
Claims10
A process for producing a cleaning solution from food waste comprising the steps of:
- removing inorganic items from the food waste, resulting in a screened waste;
- reducing the screened waste into uniform particles, resulting in a shredded waste;
- heating the shredded waste to up to 45 degrees Celsius;
- applying an inoculants solution containing lactic acid bacteria to the shredded waste and mixing the shredded waste with the inoculant for up to 48 hours, resulting in a fermentation-ready waste;
- fermenting the fermentation-ready waste until pH reaches 4 or below, resulting in a fermented batch;
- separating the fermented batch into a liquid and a wet solid;
- further processing the liquid to remove suspended particles resulting in a first liquid stream;
- drying the wet solid using heat until the wet solid achieves 50% or greater reduction in weight, resulting in a dried fermented waste;
- collecting condensate from the drying of the wet solid resulting in a second liquid stream;
- and
- processing the first and the second liquid streams together by applying up to 0.2 micron filtration and ultraviolet light treatment resulting in the cleaning solution.
