5 Overview of the SA Rendering Industry and the role that sterilizing plants play in the South African Red Meat Abattoir Waste Management Context. Richard Prentis Chairman South African Renderers Association

6 POTENTIAL RECOVERY ENERGY PROTEIN / FAT FERTILIZER

7 FEEDBACK: Alkaline Hydrolysis Stabilized Fat Is A Significant Cost Recovery Mechanism: Red Meat abattoirs can now recover a stabilized fat from the soap present in the digestate using WRT s multiprocessor technology. Fat recovery typically 45% of tissue processed assuming a normal mix of condemned tissue. Hydrolysed Protein Liquid Fertilizer Trials closes the loop HPL Fertilizer Trials provided conclusive proof that hydrolysed protein is an excellent soil ameliorant and when enriched with traditional fertilizer, produced 30%+ more biomass compared to the traditional fertilizer alone. WRT addresses need for smaller tissue processors WRT has completed the development of a small tissue processor that can process 250kg of tissue per cycle. Units will be commercially available by end June 2014.

13 MANAGING THE HYDROLYZED PROTEIN FROM THE TISSUE PROCESSOR A Liquid Fertilizer The hydrolyzed protein is an excellent liquid fertilizer due to the elevated levels of Nitrogen and Potassium. The high ph, if unadjusted, can also reduce the lime requirement but ph can be tailored to suit any type of soil if a lower ph is required.
