There are many enzymes products in the market like; EMC Squared, Permazyme, Endurazyme, Paczyme, Earthzyme, RoadTech, UBIX, ECOroads, EcoMax/Nrzyma, Zym-Tec, Terrazyme, PX300, EnzymeRoads, Corchem 5510, Roadzyme, PaveZyme, EcoTerra, and others. All contain similar substances.
I´m divulging the information below purely for humanitarian, altruistic reasons and a dream, that maybe a day, people in developing countries can stabilize the soil of the roads, earth blocks, earthbags without having to pay for trademarks and/or expensive hydraulic cements.
The enzymes for soil stabilization are made from fermenting sugar in a process similar to beer brewing, but the process continues until everything is fermented (Mihai O. M.; Ray H.; Timothy R. C.; Velasquez, R. A.. Preliminary laboratory investigation of enzyme solutions as a soil stabilizer. Final Report. Minnesota Department of Transportation, Research Services Section / University of Minnesota Department of Civil Engineering, Minneapolis, MN, 2005.
We can see information that the enzyme from PermaZyme lnternational Enzymes (and similar) are made from water, molasses, malt, yeast, sugar and non-ionic surfactant (Engineering Field Notes, volume 26, may-june 1993, United States Department of Agriculture. Dust Abatement Product Comparisons in Northern Region, figure 01, pag 27).
How to produce these enzymes: In a bioreator add warm water and agitate slowly. After add molasses and more warm water. Next add a dissolved mixture of urea and magnesium sulfate. After add a specific type of yeast (a strain of Saccharomyces cerevisiae ) and wait some days. The next step is to separate the materials adding aluminum sulfate and others substances and finally filter the ferment in a filter. We need check the ph and temperature continuously because it is a fermenting process. Observe that this is only a summary of the process where these and others steps/substances are needed.
We can´t forgot that enzymes react with the organic matter in the soil; the substances formed help in formation of the bonds between points of the the crystalline structure of the clayey materials, stabilizing the soil mass. Thus soils need to contain some organic material like decayed material.”
Thanks to RB for this information.
