From common view of millions farms all over the world, raising cattle always releases waste such as dung, urine or the excessive feed. The treatment of the waste is not easy when the raising scale is large. In addition, the bad odor from livestock is a problem that the farm owners want to eliminate but so far there has been no optimum solution.

Mr. Nguyen Viet Hoai, a Vietnamese-American inventor has disclosed a kind of bio-composition derived from natural materials which can be found every where in Vietnam. This kind of bio-composition is characterized in that it is produced in the original form with pH of less than 3.5 and it is not active. However, when it is changed into the second state by providing water and suitable organic solutions, the number of micro-organisms increases dramatically and the bio-composition becomes very active. This bio-composition is the basis for making a type of bio-buffer for raising livestock with no waste.

By filing three consecutive patent applications Nos. 1-2015-02965, 1-2015-02988 and 1-2015-03167 to claim the protection of the successful products/processes based on his pilot scale, Mr. Nguyen Viet Hoai decided to apply his inventions for breeding farms. The model was implemented in Phuc Yen district, Vinh Phuc province to introduce the advantages of no-waste raising technology to farm owners.

In the time to come, HAIHAN-IP will continue to update the applying results of the above-mentioned inventions to clarify whether the inventions can change the conventional view of livestock raising.
