Managing livestock waste is a matter for many livestock producers. (Illustrated photos)
According to statistics, the province has about 588 farms with thousands of small livestock farms. However, the planning of overall livestock development is not uniform, the distribution of farm density varies widely across regions, labor productivity is not high, environmental treatment technologies have not been properly toothpick.
Likewise, the scale of household production is low, difficult to compete, dispersed, small and difficult to manage disease. Biogas plants have been developed but only account for more than 50% of livestock households. With medium and large biogas plants, most of them do not use up their gas and most of it is discharged into the environment.
According to the statistics of the functional sectors, the treatment of solid waste (including: faeces, leftovers, animal carcasses, veterinary tools ...) in livestock is still about 40 - 70% composted , About 30 - 60% of the direct discharge into the environment or the fraction is treated with biogas. Most of the breeding facilities do not have complete treatment plants up to TCVN 37775-83.
Other solid wastes such as animal husbandry, veterinary supplies ... are almost untreated. In addition, the treatment of liquid waste (including urine, bath water, livestock, water from slaughter houses, poultry) has about 30% of treatment through Biogas, 30% by lagoon biology, the other 40% use direct irrigation, fish culture or spillage into the environment. In addition, gaseous emissions (including CO2, NH4, CH4, H2S, ...) pollute the environment and odors.
Facing with the above situation, there are many opinions of the functional branches to solve the existing difficulties in the management of animal waste such as the need to strengthen the state management of livestock environment; To review, supplement and develop technical standards and regulations, animal testing and testing procedures for state management in animal husbandry and the breeding environment; Increase budget for activities of surveying and surveying animal husbandry environment, supporting environmental protection; Priority is given to financial policies, livestock development activities associated with environmental protection; Encourage collectives and individuals with excellent achievements and great influence in environmental protection in animal husbandry. In addition, it is necessary to promptly report to higher management agencies on areas and establishments polluted environment in order to soon have management plan and overcome effectively.
