Title: Innovations in Organic Waste Treatment by Chris E Choate
Introduction
Chris E Choate is an accomplished inventor based in Discovery Bay, California. He has made significant contributions to the field of organic waste treatment, holding a total of five patents. His innovative approaches focus on converting organic waste materials into useful products, thereby promoting sustainability and environmental responsibility.
Latest Patents
Among his latest patents, one notable invention is a system and process for the treatment of organic waste materials using a biomixer. This method involves screening waste materials to produce unders and overs. The overs are treated to create a partially hydrolyzed biomass, which is then anaerobically digested. The treatment process includes fermenting and mixing the overs with aerotolerant anaerobic bacteria in a controlled environment, such as a rotating drum, while air is passed through. The moisture content, pH, and biological content of the overs can be adjusted prior to treatment. Additionally, volatile fatty acids from the air can be collected for anaerobic digestion or recirculated back into the controlled environment, while the cleansed air can also be recycled.
Another significant patent focuses on systems and methods for converting organic waste materials into useful products. This invention addresses the conversion of organic waste from municipal waste streams, including yard waste, food waste, and paper, into a uniform biomass suitable for producing fuels. The process utilizes a biomixer and a hydropulper, along with sorting and screening, to progressively reduce the size of the organic waste materials and remove contamination. The resulting biomass is ideal for anaerobic digestion, producing biogas and a residual solid that can be transformed into high-quality compost.
