Organic Fiber Mold Mitigation

There is a vast knowledge base of using chlorine dioxide gas and we are the first company to commercialize a cost-effective PLA sachet (BioArmour CDS-8) for scale markets with dry chemistry that releases chlorine dioxide gas upon coming in contact with ambient air.

Chlorine dioxide can kill bacteria, fungi, viruses and spores in contact times ranging from a few seconds to a few minutes. As a gas in its natural state, it’s 10-20 times more effective than bleach (sodium hypochlorite), highly soluble in water, compatible and effective over a wide pH range. Its use has traditionally been limited to large-volume applications, such as pulp and paper facilities and water treatment plants, which employ costly and elaborate chemical or electronic generating systems.

A highly selective attack is the key. It inactivates microorganisms by oxidizing key components in membrane proteins that are vital to the protein’s structure and function. Typically, cell death via chlorine dioxide oxidation is caused by a loss of permeability control and ultimately membrane potential. By oxidizing protein components, chlorine dioxide is reduced to benign byproducts. Also, since it goes through simple oxidation and does not proceed through electrophilic substitution, as do bleach and other halogenating compounds, no carcinogenic trihalomethanes (THMs) or haloacetic acids (HAA5) are formed. Hence, a 4-6 log reduction of gram positive, gram negative bacterial pathogens, spores and molds over a 24 hour timeframe is not uncommon for chlorine dioxide.

Our market focus for deployment of this product is mitigation of fungus in organic fiber bales. In damp weather (rain, snow), the cargo must be protected from moisture, since organic (coconut, cotton) fiber is strongly hygroscopic and readily absorbs moisture. This leads to staining of the bales, decay and mold growth contaminating the organic fiber and reducing its value.

The way our BioArmour CDS-8 product works is:

  1. Open the sachet pack and put sachet in product packaging.
  2. The sachets are manufactured from completely sustainable* PLA biopolymer (it is 100% “green”).
  3. Sachets activate the chlorine dioxide gas as soon as it comes in contact with ambient air.
  4. It releases a nominal amount of gas over a designed period of days.  They can be easily disposed of;in a landfill the sachets will degrade to carbon dioxide, water and methane in about 2 years.
  5. The gas and chemicals inside the sachets are completely depleted within the designed timeframe.

Detailed testing with the Government of India clearly demonstrated the efficacy of the BioArmour™ CDS-8 sachets over the course of 40 days, which was a 98% reduction of the mold.
