What is the typical size and design of a composting building for a 2400 head wean to finish hog building?


Compost units must be properly sized for individual swine operations. Indeed, adequate size of compost bins can be considered another requirement for composting bacteria. A composting unit is intended for routine mortality, not large, single event death losses such as a major disease outbreak or a barn fire. To properly size the composting unit, you need an estimate of the weight of average daily mortalities. You can determine the weight using farm production records or industrywide averages.

Secondly, you must calculate the necessary volume of primary and secondary composting bins. There should be at least 20 cubic feet of primary bin volume for every pound of average daily mortality. Moreover, the number and volume of secondary composting bins should equal that of the primary bins. Some storage space for additional bulking agent material may also be built into the system or located close by.

The bin dimensions must also be determined. The height of a compost bin should accommodate a maximum compost pile height of six feet and bin width should be at least 1-1/2 times the width of the mechanical equipment that will be used to load and unload the bins. Sows and larger market hogs require a minimum bin size that allows laying individual carcasses in the bin for complete coverage with bulking material. Minimum compost bin floor dimensions of 7-1/2 by 10 feet are suggested for sows and 5-1/2 by 8 feet for market hogs.
