«Rusmolco» starts a new manure disposal system.

«Rusmolco» put into operation a unique complex for intersoil manure application. This technology will allow the company to reduce negative impact on the environment and save up to USD 500 thousand per year due to reduction in fertilizers requirement.

It is a fact of common knowledge that leading milk producers all over the world make great efforts to improve productivity of their livestock, to increase yields and to decrease cost of milk production.

But not everyone knows that cows produce two times more manure than milk. A typical milking cow having weight of 650 kg produces 60 - 90 liters of manure and sewage per day depending on feed and water quantity.  In case of «Rusmolco» it is more than 500 thousand cubic meters of manure a year (to understand it better – that is 10 big swimming pools).

As a rule, all dairy farms temporary store manure in special lagoons. Number and capacity of lagoons are restricted by local legislative and regulatory acts, ecological requirements to operations and availability of free lands in companies. So, sooner or later lagoons fill up, companies’ capacity of manure storage deplete, and the question of further disposal of manure without damage to the environment, nuisance to the local population and without water pollution arises.  

«Rusmolco» that today has a herd of 12 thousand heads of cattle, has also faced this issue. Having studied the problem, specialists of «Rusmolco» have come to the conclusion that the problem of big quantity manure disposal in the Russian livestock husbandry has almost not been studied, and ready technological solutions do not exist. At the beginning if 2014 «Rusmolco» team was given a task to study the best practices in the USA and Europe, to develop an in-house design of manure disposal system suitable for hard service 24х7 in Russian weather conditions. The specialists only had several months to develop a unique project, then to purchase, to import, to perform customs clearing, and to install the equipment; moreover it had to be completed before the first autumn frosts.

By today the system has been commissioned, it works in compliance with the planned parameters, somewhere even better than planned. 

The system consists of: 4 JohnDeere tractors having capacity of 220-300 horse powers, 2 automatic-fill tankers having capacity of 26 and 40 m3, 12-meter applicators with integrally geared compressor, 2400 m of hoses with a mobile pump.  Manure is supplied under pressure from tankers through hoses mounted to applicators directly under the soil layer. Advantages of this liquid manure application technology in comparison with others (for example, surface application) are that the useful effect of the fertilizer increases, but its consumption and toxic effects on the environment decrease. Application potential of this system is up to 4200 m3 of manure per day, that is significantly more than farm requirements.

«New manure application system test results showed its working efficiency in severe weather conditions of Russia. We believe that the correct use of this technology will allow us to save about USD 500 thousand per year due to reduction in costs for fertilizers», - said the CEO of «Rusmolco» Sumanta Kumar De.

«That is the most modern example of a stable waste disposal in the Russian Federation, which is a serious task for the livestock husbandry. I am really pleased to see that such companies as «Rusmolco» bring world’s best practices of problems solution to our country», - commented the Minister of Agriculture of the Penza Region Andrey Burlakov.
