Denaturing Abattoir Waste Tissue – What is it and how can it be accomplished ?
Denaturing Abattoir Waste Tissue The South African Meat Safety Act of 2000 outlines very specific methods that are to be used when disposing of condemned abattoir waste. The four methods are: Denaturing prior to burial deeper than 600mm below ground Sterilizing Incineration Any other disposal method approved by the Provincial Executive Officer of the Department of Veterinary Public Health. In this series of articles we will be taking a closer look at each of the disposal methods individually. This article investigates denaturing and the practical implications of this method. Denaturing is...
Read MoreLocal Newspaper Highlights Animal Waste Disposal Problem
Our local Mpumalanga newspaper – The Lowvelder – today published a front page article about decomposing cow heads that were found on the bank of the Crocodile River. This article shocked many readers due to the graphic nature of the photographs, but I want to commend the Lowvelder for taking a very serious environmental issue and highlighting it in a very realistic manner. Sure, non of us really want to see pictures of rotting animal heads before breakfast, but on the other hand, it is high time that people are made aware of a environmental problem that is threatening public...
Read MoreEnzymatic Treatment of Abattoir Waste Tissue
Is it just my imagination or are there a growing number of increasingly disillusioned business owners that have one thing in common – they all dabbled with small waste disposal processes that make use of proteolytic enzymes to digest animal carcasses and condemned abattoir waste tissue? At first glance, using enzymes seems like such a logical way to get rid of all those smelly waste tissue, yet the concept in practice just does not seem to work properly on any kind of single-user scale. Despite the fact that the science behind the use of digestive enzymes is very solid, it appears as...
Read MoreDo Not Burn Condemned Meat Waste or Specific Risk Materials
Incineration of waste products is a well established method of waste disposal. It is claimed to be one of the most effective ways of pathogen destruction (provided that the incinerator is properly operated). This being the case, why is there an urgent and definite movement away from this type of technology? During the incineration process an extremely carcinogenic byproduct called dioxin is released into the atmosphere. Dioxin has been proven to be a major contributor in the development of various types of health problems, including cancer, in humans.The terrifying reality is that children...
Read MoreAlkaline Hydrolysis As A Precursory Process To Anaerobic Digestion Of Abattoir Condemned Waste
Introduction There has been a lot of talk lately about the effectiveness of anaerobic digestion as a disposal method for abattoir waste streams. The principle of turning abattoir waste streams into electricity, fertilizer and hot water is certainly attractive and provided that disease control can be effectively incorporated into this process, it is difficult to find a more suitable and comprehensive way to dispose of the total waste stream generated by abattoirs on a daily basis. The One Fatal Flaw of Anaerobic Digestion The anaerobic digestion process by itself does not provide adequate...
