Vermicompost Technology / Sharifah Amirah Syed Salim and Nursyazni Abdul Rahim

Vermicomposting is a biological waste management technology in which the organic contents of wastes are degraded by microorganisms and earthworms and converted into components that can be organised, reserved, and applied to agricultural fields under favourable environmental conditions without harming the environment. This method may be adequate for converting discharged muck into useful chemical. According to research by Yadav and Garg in 2011 entitle Recycling of Organic Wastes By Employing Eisenia fetida proposed that agricultural residues, animal excreta, as well as municipal and industrial organic wastes, are commonly employed as the vermicomposting medium since they are nontoxic, salinity-free, and degradable. Lots of studies also have been conducted on vermicomposting of animal dungs, sewage sludge with agricultural and industrial waste. For instance, production of vermicomposting technology is nutrient rich clay-like material; vermicompost, it will possess more available nutrients per kg weight rather than organic substrate in parent wastes. Furthermore, due to humification and a faster disintegration process, it is extremely fragmented, spongelike, and microbially active as compared to original ingredients as noted by Sangwan et al. (2008) in their research about Vermiconversion of Industrial Sludge for Recycling the Nutrients.
