As sand and manure mix in cow bedding, the material becomes contaminated and unviable for reuse. The CDEnviro treatment recovers both sand and manure individually, which can then be treated and reused.
The Benefits of Sand for Cattle Bedding
Sand is a desirable material for cow bedding for a number of reasons. It is widely thought that with sand bedding clinical mastitis is less likely to occur than with organic bedding, as there is less opportunity for bacterial growth. In addition to that, from the cows’ perspective, sand is comfortable to lie on and unlikely to cause bruising. It also helps the cows with balance when reclining and rising, reducing the likelihood of lameness.
Although sand bedding carries a number of benefits, sand and manure mixture causes the material to be contaminated and unviable for reuse. This of course brings with it a high cost for dairy farmers who must constantly replace the contaminated sand with fresh bedding. Outside of using the sand-laden manure in agricultural applications, the uses of the material are limited and some farmers may have to landfill their excess material.
Mechanical Separation is a beneficial treatment to solve the problem of dealing with sand-laden manure. The CDEnviro treatment of the sand-laden manure recovers both products individually, which can then be treated and reused. The manure can be used in agricultural applications, used to create energy through anaerobic digestion, or even be composted. This increases profits and eliminates the need for waste disposal. Meanwhile, farmers can reuse the separated sand in the cow beds, again reducing costs of fresh cattle bedding.
