NATSURV 7: Water and Wastewater Management in the Red Meat Abattoir Industry (Edition 2)
Expanded Title:Internationally, red meat abattoirs (processing cattle, sheep, pigs, ostriches) are known to be high volume water consumers. Similarly, they are also serious polluters of water due to their effluent. During the 1988 NATSURV 7 survey period, there were 25 registered abattoirs throughout South Africa. The ten large metropolitan abattoirs (owned by Abakor) processed approximately 50% of the national red meat requirements. In these then large abattoirs, weighted process water consumption ranged between 0.7 kl and 1.2 kl per slaughter unit (SU), whilst in smaller abattoirs consumption figures of as high as 4.64 km per SU was recorded. When the South African meat industry was deregulated in the 1980s, most of the large abattoirs were closed down and smaller abattoirs proliferated. Managers of smaller abattoirs are quite often not seriously concerned with water consumption and effluent quality, as they focus on the quality of meat, which is their core business. Abattoirs in the category of 2 to 20 slaughter units now (2015) represent 45% of the slaughter capacity in South Africa. Water consumed per SU increases inversely to the abattoir slaughter capacity. Average consumption for large abattoirs is 0.91 kl/SU, increasing to 2.04 kl/SU, (124 %), for small abattoirs. Wastewaters similarly have typical chemical oxygen demand (COD) values of approx. 1200 mg/l in large abattoirs and approx. 5000 mg/l in small abattoirs. Abattoir management can greatly influence the volumes of water consumed as well as the quality of effluent produced in red meat abattoirs. Reducing water consumption and improving effluent quality can have major impacts on the financial viability of red meat abattoirs. To assist abattoirs in reducing water consumption and improving effluent quality, thereby reducing production costs, a best practice guide has been provided. Finally, a detailed action plan has been supplied.
