Pig farm manure – polluting or nutrition matter?

19. May 2012.

 

In order to exchange knowledge and experience Carnex actively participates in the most important conferences in the field of environmental protection in order to educate the public on environmental projects and implemented actions.

The Association for Water Technology and Sanitary Engineering held an international conference in the field of municipal and industrial wastewater, solid utility waste and hazardous waste in April in Cacak.
Work named "Pig manure – polluting or nutritive matter?" was published in the proceedings of the International Conference and it serves to educate the interested public with the results of environmental monitoring that Carnex continuously implements.

Commercial feed is often enriched with essential elements, such as certain metals (Cu, Zn, Mn, Fe, Co, Mo, Se, etc.) that promote an optimal supply of nutrients and therefore optimum growth rate of animals. Pig manure in addition to being an excellent source of nutrients and organic matter for plant growth and development in the agricultural production is also a potential risk of metal accumulation in the soil if used incorrectly.

As one in a series of environmental projects, Company Carnex installed mixers and separators of liquid manure form waste water in order to reduce polluting the surface water at its pig farms. Also, following the recommendation of the EU Nitrates Directive contributes to the prevention of increasing concentration of nitrate in ground waters and by proper use of solid and liquid pig manure in agriculture reduces pollution artificial fertilizer.
