“…After the initial decrease in CO 2 concentration, it increased. This was probably caused by earthworms facilitating the enzymatic and microbial degradation of organic matter resulting in the transformation of wastes into organic humic forms with a significant release of CO 2 [67]. The decrease in CO 2 emissions in week 12 of this study may be attributed to stabilization of the compost as reported by Nada et al [25].…”

“…The high CH 4 content in week 4 may be attributed to low oxygen concentrations resulting from the relatively high moisture content of the cattle manure substrate in the vermicomposting units compared to the other weeks with measurements ( Table 3). Low oxygen content and high moisture content cause anaerobic conditions in vermicomposting units, hence stimulate the development of methanogenic bacteria that produce CH 4 [66,67]. A reduction in the CH 4 concentration in week 8 and further in week 12 may be attributed to an increase in the earthworm population.…”

Growth in cattle population is associated with increased manure generation whose current management in low-income countries is associated with health and environmental problems as well as low utilization rates. This trend can be reversed by promoting better manure management technologies. This study assessed vermicomposting as one of the technologies to manage organic wastes, using the case study in Uganda. A vermicomposting system using cattle manure and earthworms (Eudrilus euginea) was monitored for one year with the harvesting of products (compost, earthworm biomass) after every three months. Vermicompost samples from the beginning of the experiment and after every harvest were analyzed for the following parameters: pH, ash content, volatile and total solids, nutrients N, P, K, and C. Emissions of CO2, CH4, NH3, and N2O were also measured. Material flow analysis was used to determine the flows and retention of nutrients within the system. Results showed that total solids, ash, N, P, and K content significantly increased, while contents of volatile solids and C, as well as the pH, significantly decreased over time. Of the materials that entered the vermicomposting system, 46% went to vermicompost, 2% into earthworms, and 52% was lost to the atmosphere. Substance flow analysis showed that 30% of C went to vermicompost, 69% was emitted to the atmosphere, and 2% ended up in earthworms while 75% of N was transferred to vermicompost, 7% went to earthworms, and 18% escaped into the atmosphere. The cumulative emissions were 102 g CO2 kg−1 waste, 7.6 g CH4 kg−1 waste, and 3.943 × 10−5 g N2O kg−1 waste on a dry basis, while NH3 was not detected throughout the measurement time. Compared to other manure management methods, vermicomposting demonstrated good potential in conserving nutrients as well as reducing greenhouse gas emissions.

“…Non-thermophilic biodegradation of organic matter into humus like substances, as a result of feeding earthworms, is referred as vermicomposting (Arancon et al, 2004;Arancon and Edwards 2005;Swati and Hait 2018). During this process organic waste materials pass through the gizzard of earthworms (Ndegwa and Thompson 2001;Hemalatha 2012) and produce vermicast which is rich in essential plant nutrients and unidentified plant growth inducing compounds (Sharma and Garg 2019).…”

With the rapid growth of global population, food production and waste management are considered to be two major challenges faced by people in 21 st century. Though application of chemical fertilizers enhances crop growth, vigor and yield thereby meeting the food security, it depletes the quality of environment and ecosystems. Recycling of organic wastes is considered to be a feasible solution which could mitigate the issues of waste management while uplifting the status of soil health and nutrients. The objective of this article is to reviews the currently available literature on vermicomposting as a tool for recycling of different organic waste materials and subsequent use as organic amendment to improve soil properties and as organic fertilizer to enhance growth and yield of various crops. Furthermore, models were proposed to improve education on vermicomposting as a solution for organic waste management among farmers, students, government offices and general public and develop as a community based microenterprise. Vermicomposting is defined as a process where earthworms convert organic wastes into humus like materials. It has been investigated worldwide taking its practical significance into account. Vermicompost is found to be a good source of plant macro nutrients, micro nutrients and growth regulators, including humic acid, indole acetic acid and kinetin. Microbes live in the alimentary canal of the earthworms improve the quality of vermicast hence vermicompost. Furthermore, vermicompost could absorb heavy metals in soil and water while eliminating of human pathogens such as Salmonella spp, fecal coliforms, Shigella spp, Enterobacter aerogenes, Enterobacter cloacae and eggs of helminthes. Reviewed literature indicated the potential of vermicomposting to be used as an efficient technique for bioconversion of organic wastes into a valuable organic fertilizer. Furthermore, the present review suggests vermicompost production as a micro-enterprise which could be used to uplift the livelihood of the resource poor farmers through economic empowerment while assuring sustainable crop production.

“…In 2016, 5% of global emissions were generated from solid waste management, excluding transportation. It is estimated that human activities are causing global industrial warming of approximately 1° C, with a weighted margin of 0.8 to 1.2°C [15]. Global warming is likely to reach 1.5° C between 2030 and 2052 if it continues to increase at the current rate [16].…”
