Management of Soil and Water Contaminated with Heavy Metals with Sustainable Green Technologies: The Case of Vermicomposting

Countries are searching for alternative energy sources because of the global impact of greenhouse gases and the possibility of an energy crisis. In this regard, innovative technologies like composting are becoming more and more popular around the globe as a means of getting rid of municipal solid waste in agricultural areas. Composting is a biological process that creates an earth-like structure called compost by means of microorganisms converting organic materials, such as animal excreta, sludge from biological treatment plants, leaves, paper, and food waste, among others. One benefit of composting is that it helps to keep the environment clean. Organic material is stabilized through composting. It is well known that earthworms improve the fertility of the soil and the quality of the produce that is grown there. By passing soil through their bodies, they are able to attain this increase. The worm's body goes through a number of processes with the soil that it sends into the digestive tract along with the nutrients it absorbs. The worms provide the soil with essential nutrients by releasing their excrement, which is a highly valuable fertilizer into the surrounding environment. Practically all of the minerals required for plant growth are present in this vermicompost. Vermicomposting and composting differ primarily in that vermicomposting does not undergo the thermophilic phase of composting. Additionally, as the worms’ digestive tracts process the waste to be processed, the heavy metals in it are stabilized and separated from the fertilizer during the vermicomposting process. For all of these reasons, research on vermicompost (also known as vermicomposting) and its use in rural areas has expanded both domestically and internationally in recent years. The issue of declining organic matter in agricultural soils is addressed in developed nations through the use of conventional organic fertilizers; however, vermicompost fertilizers are also an effective solution. In actuality, everything here is about preserving a healthy ecosystem for next generations by preventing chemical pollution of agricultural products and soils.
