The End of the Rendering Plant

The End of the Rendering Plant

I have been working on DCD Technology full time since 2020 but have been looking at its application in the meat industry since at least 2016. The applications are many. It makes meat-on-meat injection for bacon injection possible without the hassles associated with current systems.

See my article: Meat-on-Meat Bacon and Ham:  Injection for Profit and Taste

The company that invented the DCD system is Green Cell Technologies. Here is a press release and introductory video they release last month. It introduces you to the technology and explains what DCD technology is.

See the press release: Disrupting the Meat Market

I house the work on DCD technology under my work on emulsions, Nose-to-Tail and Root-to-Tip, but it is much wider than that. The rendering plant has traditionally been the wastebasket of the abattoirs but this is about to change. DCD technology requires no heating and when we processed the full 5th Quarter, we end up with a POSITIVE yield. Using DCD Technology one can process:

  • Blood (for animal feed and fertaliser)
  • Hair (for animal feed and fertaliser, increasing digestability to levels far above what is normal for keratin)
  • Hide (extract collagen for human consumption and the rest for animal feed)
  • Hooves (for animal feed)
  • Intestines including the stumick matter (approved intestines for human consumption; rest for animal feed)
  • Tandons (the collagen for human consumption)
  • The bones (the collagen for human consumption)

DCD plants are set to replace rendering plants and make a range of raw materials available to local meat processing including collagen and other functional ingredients which has in recent years been traded through the spice industry. This technology has been packaged in equipment that is easy to maintain and install anywhere in the world. Its use will eliminate abattoir waste completely. It will wrestle back meat technology from the hands of the spice industry to the meat industry who should be the rightful custodian of meat processing technology.

The Power of Microparticles: Disruptor (DCD) Technology

Current Ongoing and Future Projects

– Lab Work

At the moment I am working my way through the full 5th quarter and doing the lab work required to give us the full scientific understanding of the power behind DCD Technology.

– Factory waste

We are starting trails next week whereby we will eliminate all factory meat waste by DCD’ing all such waste and producing high-quality pet food for a local meat processor.

– Back to nature

We are able to process potatoes and other tubers and grains, rich in starch. The equipment owners will be able to produce their own starch, dietary fibres and sugars. By understanding the composition of potato, to use one example, formulations can be re-worked where potatoes are used that has been DCD’ed to replace highly concentrated and processed starch, fibres and sugars customarily added to the meat block for sausages, etc.

– Vegetable Sausages

Over the last 75 years or so a very unfortunate trend emerged in meat processing whereby meat hybrids emerged which is a combination of serials, grains and meat. We continue to call these products meat but in reality, it is not pure meat. While it is a fact that we consume far too much meat and too little fruits and vegetables, we are often limited in our choices for little-processed fruits and vegetables that can be taken to work or school and that will fill us enough to do our work. The accompanying trend for imitation meat is even more worrying.

DCD technology makes it possible to produce vegetable and grain-based sausages without the inclusion of any meat so that the producer can offer the consumer the option of pure meat products and fruits and vegetables that are produced with no additives or e-number ingredients but packaged in convenient ways like sausages or nuggets. It allows for people to completely move away from imitation meat products which are packed with highly processed functional ingredients. Consumers have options to reduce their meat intake with the peace of mind that the meat they eat and the vegetables they consume are minimally processed and yet, safe to consume and conveniently packaged for the modern family with all our unique demands.

We are busy with all these developments! DCD Technology makes it possible!

Feedback Videos

Below is a list of my own feedback videos. All products have been made using DCD Technology at a fraction of raw material cost compared to if one would procure it through the spice trade or other channels.

Pork Stomach

80% Beef Collagen, 20% Beef Fat.

Processing pig hooves (Keratin) into highly nutritious animal feed with DCD Technology.

Here we made a fat replacer with 60% collagen which we obtained from beef tendons and skin with DCD Technology and beef kidney fat. We added about 20% water. 2.5kg fat makes 15kg final product.

Processing pigs hair with DCD Technology ensures high digestibility. The relationship between digestibility and comminution has been firmly established in recent literature.

Case Study 1: Pork Rinds

After DCD:

Pork Rinds, Functionals and Water DCD’ed together.

Look at the product consistency. One could inject it!

After setting for 12 hours in the fridge, the rinds form a stable and sterile gel which can be added to a bowl cutter or emulsifier for inclusion in a fine emulsion sausage recipe.

Case Study 2: Creating collagen rich “smoothies” for the health industry or high quality pet food.

Case Study 3: Pork Trim 80/20

80/20 pork trim DCD’ed.

DCD’ed 80/20 Cured Pork Trim. The consistency is such that it can be injected, even under low pressure. Temperature is kept sufficiently low not to denature the proteins.

Case Study 4: Dcd’ed Fat Replacer After Setting Overnight

Collagen DCD’ed and chilled overnight to set.

After chilling overnight to set, the mix is minced.

After chilling it overnight, a paste is formed, stable enough for mincing and inclusion as a possible fat replacer.

End-uder Feedback of Final Product

Final products and comments by clients who tasted the final products are featured in this section.

The commentary is in Afrikaans but you can tell the Dei owner is very happy!

The fact that DCD is set to change the way meat is processed can not be disputed. Functional ingredients that are subjected to high processing will become something of the past and this new look at how we do things will make food more affordable and substantially contribute to making food less processed. The British Agency for Food Safety talks about food that must be consumed in the way that it would be done if nothing is refined, extracted and concentrated. All this becomes available to the processor through DCD Equipment and technology.

Rendering plants as the wastebasket for the abattoir is something of the past, to be replaced by this new technology. Instead of a wastebasket, what is about to replace it is a completely new concept which materially contributes to the future of our lives on earth!
