Is Alkaline Hydrolysis An Effective Treatment Method For Hatchery Waste?
Article by Piet Kruger Ever wondered what happens to the egg shell after the egg hatches? To be truthful, neither did I until recently when I received two separate requests from two different provinces in the same week asking if hatchery waste could be treated using our alkaline hydrolysis technology. Broken chicken eggs at the start of the hydrolysis process Normally I would be able to provide an answer, or at the very least give an educated guess immediately, but to my utter embarrassment, this time I was stumped. The problem as outlined was as follows. Hatcheries deal with eggs (duhh!)-...
Read MoreNitric Acid – a dangerous but very useful tool.
Good old Nitric acid (HNO3) also known as Aqua Fortis or Spirit of Nitre. Nitric acid is categorized as a strong oxidizing agent, meaning that it does not typically donate its proton. We all know that any acid has a pH of less than 7. Commercial grade nitric acid typically has a pH of –1.4 as opposed to vinegar that falls around pH 3. No bonus points for guessing that Nitric acid oxidizes just about anything non metallic to its highest oxidation state. Metals are often passivated, i.e. oxidized to the extent where a corroded layer forms a capsule around the metal protecting it from further...
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...
