A booster composition for enhancing biogas yield in biomethanation
A recently granted patent (Publication Number: US11773413B2) describes a method for enhancing biogas yield and stabilizing the operation of a biomethanation plant. The method involves several steps, including homogenizing organic waste, loading it into a digester with water at a specific organic loading rate, adding a biomethanation inoculum, and creating an anaerobic environment by flushing the digester with an inert gas.
One key aspect of the method is the use of a booster composition, which is dosed into the digester after one week of operation. The booster composition includes various components such as controlled release agents, redox potential balancers, direct interspecies electron transfer (DIET) improvers, micronutrient balancers, and co-factors. These components are mixed in a specific manner using a base medium of 10% formic acid to create the booster composition.
The patent also mentions that the booster composition can be subsequently dosed into the digester at a gap interval of 2-3 weeks. The method can be applied to different types of digesters, including covered anaerobic lagoon digesters, plug flow digesters, complete mix digesters, dry digesters, and continuous stirred tank reactor (CSTR) based digesters. The booster composition can be dosed at temperatures ranging from 5-80°C and at a rate of 25-100 ml per ton of organic waste.
The patent further describes the use of specific biomethanation inoculums, which include various microbial strains, for carrying out the biomethanation process. The inoculum is grown anaerobically at 37°C for 7 days before being added to the digester.
Overall, this patent provides a detailed method for enhancing biogas yield and stabilizing the operation of biomethanation plants. The use of the booster composition and specific inoculums can potentially improve the efficiency and effectiveness of biogas production from organic waste.
