How Do You Recover Oil-Polluted Soil Using Organic Waste?
Oil-contaminated soil creates unimaginable health problems. An immediate organic solution to this sticky problem is chicken manure with spent brewers’ yeast. Chinese scientists found that adding chicken manure to contaminated soil degraded oil in soil 75 percent in only two weeks. Professor Simon Cyril Ugwumba Nwachukwu of Nigeria completed a study that successfully recovered soil contaminated with crude oil using spent brewers’ yeast. Spent brewers’ yeast is a byproduct of brewing beer. Combined with animal feces, it raises soil pH levels, optimizing yeast bacteria that absorb oil. The use of microorganisms to degrade hazardous waste—a process called bioremediation—is organic, nontoxic and inexpensive. Shovel up all visible oil. Remove and transport to an authorized landfill location. Pour spent brewers’ yeast over contaminated area at ½ lb. per square yard. Cover yeast-soaked soil with organic soil and chicken manure. Apply ½ pound of each per square yard. Till organic soil, chic
