Animal Blood

Blood as a Biological Waste Product is very unique and interesting. It is a very rich source of nitrogen AND infectious agents.

Because of the health risk, the use of blood in animal feeds has been outlawed. Disposal of blood is very risky in untreated form, yet the potential benefits of this nitrogen rich source, as a fertilizer is immense.

Current practices of disposal of untreated blood range from composting, irrigation to flushing it down the sewerage system. Municipalities, health, environmental and water management agencies are increasingly clamping down on this practice because of the obvious health risks and the high Biological Oxygen Demand (BOD). Water and Utility penalties can be astronomical and seems to be more effectively enforced.

We have developed the technology and the equipment to convert blood into fertilizer on site. This is in line with our philosophy of treating the problem at the source. The Blood to Fertilizer unit will provide pathogen free fertilizer that is stable and can be stored for months without the typical foul odour associated with decomposing blood.

Piet, we are under pressure from our local council to remove as much blood as possble from our abattoir discharge water. We want to try and dispose of the blood through composting, but we have a lot of problems with coagulation and bad smells. What can we do?

Deedrik,

You can either use our proprietary method to permanently stabilize and sanitize the blood, or you can add a variety of chemicals to the blood as a temporary measure. Traditionally Citric acid is used to prevent coagulation during short-term storage and smell can be suppressed through the addition of products such as Sodium Metabisulfate.

A word of caution, the traditional methods do not reduce pathogen loading, and the effects are temporary at best...

Rift Valley Fever

Rift Valley Fever affects primarily domestic livestock, but can be passed to humans causing fever, generalized weakness, back pain and dizziness.

Infected mosquitoes spread this viral disease and therefor outbreaks of Rift Valley Fever is more common during periods of heavy rainfall.
