Waste plastics into energy South Australia develops anaerobic digestion technology
South Australia is developing the first anaerobic digestion technology to convert waste plastics into energy and fertilizer systems
waste plastics to energy South Australia develops anaerobic digestion technology
the system is abbreviated as Poe, which is the abbreviation of polymer, organic, energy and treatment. The poet system is expected to have two machines, each of which can handle 20 tons of waste plastics per week. This technology was developed by David Thompson. After years of research and testing in the coal chemical industry park of Haigang Economic Development Zone, he gradually expanded this process into "a positive business model"
thompson said that this plastic energy technology has been successfully applied to polyethylene, polypropylene, polystyrene and expanded polystyrene so far. "The anaerobic digestion process varies with raw materials, but also depends on temperature and system stability." Thompson added that he has the ability to control plastic degradation and that bacteria can completely digest polymers that are free of toxins or heavy metals
thompson said, "pot system is a microbial digestion system, which can quickly carry out microbial digestion. I think this is the key to making it a business opportunity." At present, Thompson has received favors from 600 tons away from the sea, including a large consortium in South America, who are very eager to apply this technology
at present, these two Poe machines will be built in the sewage treatment plant in Victoria, Australia
the same microorganisms will treat plastic and water at the same time. Then the microorganisms die, leaving behind liquid and solid biomass that can be used as fertilizer, as well as biogas that can be separated into methane and carbon dioxide. These methane can be used to produce heat and energy, power sewage treatment plants, and capture and reuse carbon dioxide
thompson said, "plastic enters the anaerobic state of wastewater, and microorganisms can digest plastic and produce energy."
every year, more than onemillion tons of contaminated plastics that are not suitable for recycling are transported to landfills in Australia. In the United States, this figure has not been industrialized nearly 10million tons
thompson said that this system will not have an impact on the existing recycling system, because the system is targeted at landfills and adds new sources of revenue for companies in the waste industry
