“…The increase in the TN concentrations at the end of the process was due to the loss of carbon in the form of CO 2 through the decomposition of the substrate. Besides, the excreta and polysaccharides of earthworms as well as tissue decomposition from dead earthworms enriched the TN concentration in the reactors [21,66,71,72] The results obtained in this research also coincided with other experiments with OP waste, cattle manure and filter cake, reporting an initial TN content of 1.57% with variations throughout the process, finally obtaining 3.37% in 105 days [16,73].…”

“…Table 3 shows the values obtained at the end of the seven weeks of the vermicomposting process for the four mixes. In the first four weeks, low humidity contents were registered, probably as a consequence of the biodegradation of OM during the vermicomposting process [66]. The humidity content is crucial for the controlled evolution of the biodegradation process [67].…”

The industrialization process of oranges generates waste, which is inadequately disposed of; this produces adverse effects on the environment. Among the alternatives for valorization is the vermicomposting process, which consists of the degradation of organic waste through the action of earthworms and microorganisms. Therefore, this research aimed to study this process using orange peel (OP) waste at the laboratory level. For this purpose, it was necessary to determine the degradation conditions through the monitoring of physicochemical parameters (temperature, pH, humidity, organic matter (OM), total organic carbon (TOC), total nitrogen (TN) and the carbon/nitrogen (C/N) ratio). To balance the substrate’s nutrients, load material (LM) that included vegetable waste and eggshells was added to three different mixtures: M1 (50% OP + 50% LM), M2 (40% OP + 60% LM) and M3 (60% OP + 40% LM). To condition the substrate for earthworm (Eisenia fetida) activity, a previous precomposting process was performed. The results showed that all the mixtures fulfilled the requirements for a quality and mature vermicompost; however, the highest concentrations for TN were in the mixtures M1 and M2. The total time required for degradation of the OP waste was 13 weeks.

“…Karmegam et al, (2019) used sludge produced by paper industry, green manure and cow dung to prepare vermicompost using Eisenia fetida successfully. Lantana camara, a perennial weed species which threatens native ecosystems could be converted into vermicompost by earthworm specie of Eisenia fetida and Eudrilus eugeniae in a mixture of cow dung (Devi and Khwairakpam 2020). Joseph et al (2020) suggested that cattle solid wastes generated from indigenous cow breeds were preferred by epigeic earthworm species Eudrilus eugeniae over exotic cow breeds.…”

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.

“…Otherwise, the large biomass of invasive weeds needs to be utilized properly according to the local requirements. For instance, obtaining natural cellulosic fibers from the stem of Ipomoea staphylina (Santhanam et al, 2016); Lantana camara sticks for making furnitures, artifacts and baskets (Negi et al, 2019); Lantana camara and Parthenium hysterophorus for vermicomposting (Devi and Khwairakpam, 2020a;Hussain et al, 2016a).…”

The introduction of indigenous or exotic weeds to the habitats outside their native range and their successful colonization is defined as biological invasion which ultimately poses threat to economy, environment and biodiversity. In the present study, the invasive plant species with special reference to the invasive plants in Salem District, Tamil Nadu, India and the possible threat to the local biodiversity by their invasion has been investigated. The study focused the rapid spread of invasive weeds, Alternanthera ficoidea (L.) P. Beauv., Alternanthera philoxeroides (Mart.) Griseb., Chromolaena odorata (L.) R.M.King & H.Rob., Ipomoea staphylina Roem. & Schult., Lantana camara L., Parthenium hysterophorus L. and Sesamum alatum Thonn. In view of the biodiversity threat by these invasive weeds, possible utilization of weedbiomass through vermicomposting is addressed.
