Turn waste into treasure! Pig manure can be sold for 380000 a year.

Pig excreta will cause pollution to the environment if it is not handled properly. China has also issued a series of environmental protection policies, which put forward strict requirements for the pollution control of pig farms. Last year, a large number of pig farms with substandard environmental protection were closed across the country, which also affected the stock of breeding sows, which is one of the reasons for the rise in pig prices. Muyuan shares dispose of pig waste, which not only does not pollute the environment, but also creates profits for the enterprise. Let's move on to the reporter's investigation.

Reporter Zhang Hao: these are the fermented pig manure around me. There are about 1000 square meters of pig manure in this area. These pig manure will be used to make organic fertilizer. 99.98 per cent of Muyuan's revenue last year came from pig farming, and the remaining 0.02 per cent came from pig manure, which generated about 380000 yuan in revenue for Muyuan last year.

The treated pig manure has no smell at all and is an ideal raw material for the production of organic fertilizer. The purchase price of pig manure is 20 yuan, and pig manure can produce 1 ton of finished organic fertilizer. The price of organic fertilizer is 800-1400 yuan per ton.

Assistant to the organic fertilizer manager of Xu Qian Muyuan Industrial Co., Ltd.: our company is the only large-scale manufacturer of organic fertilizer for pig manure in the country. at present, our products are mainly fruit tree special fertilizer, kiwifruit special fertilizer, vegetable special fertilizer, and small packaging flower fertilizer, as well as most of the general fertilizer, mainly these. At present, in the market, the proportion of pig manure processed into organic fertilizer is not very high, the main reason is that many of them are scattered farmers, and their pig manure is not convenient to collect, that is, there may be a phenomenon of resource loss.

In addition to pig manure can be used as fertilizer, pig urine is also a good fertilizer after treatment. The reporter saw that there are many small white round piles arranged regularly in the green wheat field, which are the valves for transporting biogas liquid. When farmers need to water the land, they can use it by connecting a hose. The biogas slurry is provided to farmers free of charge, saving them a lot of money in watering and fertilizing.

Reporter Zhang Hao: after the pig excrement is separated by dry and wet, the pig urine is transported here after fermentation. This is the biogas slurry storage tank. Biogas slurry can be used as a substitute for chemical fertilizer, and it can be used as both water and fertilizer, as well as irrigation and fertilization. When nearby fields need to be fertilized, the biogas liquid is piped into the fields. According to their calculations, using biogas slurry fertilizer can save 200 yuan per mu of land, and the yield can be increased by 30% to 50%.

Villagers of Huangzhan Village, Neixiang County, Neixiang City, Henan Province: in the year before last, in the year before last, some wheat harvested 1 bag, some received 2 bags, some collected 3 bags, and my 2 mu and a half land collected 22 bags.
