Waste recycling

There are a few common methods of waste recycling within feedlots, with the most common being spreading it back on the cropping fields used to feed the livestock. Generally, feedlots provide bedding for their animals such as straw, sawdust, wood shavings, or other byproducts from crops (soybean chaff, corn chaff), which are then mixed in with the manure as the livestock use the bedding. Once the bedding has outlasted its use, the manure is either spread directly on the fields or stock piled to breakdown and begin composting. A less common type of recycling in the feedlot industry is liquid manure which is where minimal bedding is found in the manure, so it stays a liquid and is then spread on the fields in a liquid form. Increasing numbers of cattle feedlots are utilizing out-wintering pads made of timber residue bedding in their operations. Nutrients are retained in the waste timber and livestock effluent and can be recycled within the farm system after use. Biogas plants are also able to use livestock manure to create biofuels, but most farmers cannot afford to lose their valuable nutrients found in the manure which they use to spread on their fields.
