It also analyzed the before and after impact of irrigation on the surrounding environment. In 2019, it has completed 10 biogas slurry and residue policy briefings, 20 wastewater management seminars, 10 demonstration seminars for digestate land application, and 1 seed teacher seminar. When the project starts, there are 16 single-windows in counties and cities set up and operated to counsel the field application of digestate and declaration of water pollution fee payment. During the period, it held one time to assist the livestock industry to apply for the consent of the use of biogas slurry and residue farmland, 40 times to assist the livestock industry to propose plant irrigation that meets the water release standard, and assist the livestock farmers to declare the first phase of water pollution fee in 2021, and the declaration payment rate reached 98 %.
