Abstract

Excerpts from the report: The utilization of the offal and shed blood from animals slaughtered in the large abattoirs and packing houses of this country leaves little to be desired. Waste is carefully controlled, and sanitation is safeguarded. The advantageous and sanitary disposal of the offal and blood from the large numbers of animals butchered on farms and in small retail establishments, however, constitutes in the aggregate a problem of some importance. The investigation reported in this circular was undertaken to develop a satisfactory method of disposal for this perishable refuse whereby the valuable nitrogen and phosphoric acid might be conserved for use as fertilizer. The following methods of disposal were investigated: (1) Live-steam rendering of offal; (2) open-kettle rendering of offal; (3) preserving wet tankage, raw blood, and cooked blood with quicklime for the production of fertilizer material; (4) preserving and converting into fertilizer raw offal, wet open-kettle tankage, and raw blood by mixing them with superphosphates, with and without absorbents; and (5) treating raw offal and tankage with sulphur and absorbents to preserve them for fertilizer purposes.
