Vermicomposting is a method of composting by using earthworms, in this process earthworms eat biodegradable wastes (Such as vegetables and fruits peels), and they break down these natural materials into organic fertilizer. Vermicompost is generally used for organic farming and also maintains the health of the soil. The amount of Nitrogen is more as compared to Phosphorus and Potash in vermicompost. Vermicompost doesn’t harmful to the soil and also helps in increasing the nutrient content of the soil. The life of earthworms is 4 - 8 years depending upon the species. The nutrients contents like ...

Vermicomposting, or worm composting as it is more commonly known, is the process of using worms to break down discarded food and other organic wastes and convert them into compost and liquid fertilizers. Not only will this process save you money, but it will also downscale your environmental footprint. Vermicompost systems can be purchased online or assembled cheaply by up-cycling materials found around the house or at a local thrift store. Why Vermicompost?

Vermicomposting through biochar gave maximum increase in soil fertility with maximum decrease in C:N ratio and shows conversion of harmful wastes into useful fertilizer.

The burning of wood to dispose thereof generates large amounts of carbon dioxide (CO2), one of the critical greenhouse gases. However, vermicomposting of woodchips is a desirable and safe disposal method that requires no combustion and has the additional benefit of being a potential organic ameliorant. This study evaluated the cumulative amount of CO2 produced during vermicomposting of Quercus rubra (QR) and Pinus sylvestris (PS) compared to the amount of CO2 that evolved from burning the wood. The experiment was conducted over a period of 100 days in plastic pots in a greenhouse. The compost ...

Producing more food sustainably from the limited and scarce land and water resources to feed ever-growing population of 9 billion people in the world by 2050 is a challenge for the human kind in the 21st century. Neither the quantity of available water or land has increased since 1950, but the availability of water and land per head has declined significantly due to increase in global human population. For example in India per capita arable land availability has decreased from 0.39 ha in 1951 to 0.14 ha in 2001 due to increased population from 361 million in 1951 to 1.02 billion in 2001 whic...

The results indicate that the water hyacinth solid waste can be converted into useful energy rich biofertiliser in ecofriendly and economically viable method.

In most developing countries, municipal sewage sludge end-use practices appear unsustainable; rather, it poses environmental concerns. This study examined the potential of vermicomposting of municipal sewage sludge and its blend with other biowaste for agricultural application. Using a response surface methodology and the Box-Behnken design in Design Expert Software (Version 10.0.7), the current study optimized the moisture content (60-90%), turning frequency (1-3 turnings/week), and substrate mixing ratios (50:50 to 80:20 wt.%) to maximize the content of nitrogen, phosphorus, and potassium. A...

____________________________________ Abstract: Vermicompost, a nutrient-rich organic fertilizer produced by vermicomposting, has emerged as an environmentally acceptable and sustainable waste management and organic agriculture option. It investigates the production, economics, and sustainability of vermicompost. Vermicomposting is the process of collecting organic waste and feeding it to specific earthworm species. Worms digest organic materials, transforming it into nutrient-rich castings that are collected and cured. Vermiculture has the potential to be profitable economically. Consumer awar...

By-products of various industrial fermentations can be good adsorbents for removing hazardous dyes from wastewater. However, after biosorption, regeneration of biomass is essential to minimize the solid waste generation or else the dye laden biomass should be suitably disposed off. In the present work, experiments were conducted on the Acid Navy Blue and Methylene Blue dyes which were biosorbed to the fungal biomass (strain closely related to Aspergillus lentulus) produced on corncob as the substrate through solid state fermentation. In order to dispose the dye laden biomass, it was vermicompo...

The Carter Holt Harvey Kinleith pulp and paper mill has undertaken huge efforts to minimise its landfilled organic wastes over the last decade. Besides increasing fibre recovery rates options for alternative uses of pulpmill solids have been evaluated over time. In 2008 a feasibility study of industrial scale vermicomposting of Kinleith pulpmill solids was been initiated. After proofing of concept, Noke Ltd. started operating its industrial wormfarm at full scale, vermicomposting all primary solids from Kinleith mill. In 2010 trials of mixing the secondary biological solids from the oxidation ...

The large quantity of organic waste, nearly 700 million t yr-1, generated in India is either burned or land filled posing a problem of safe disposal. To mitigate this problem all the waste can be converted into highly valuable nutrient-rich compost in an environment friendly manner. Vermicomposting is one of the best methods of composting any kind of organic matter, which could provide a ‘win-win’ solution to tackle the problem of safe disposal of waste and also provide most needed plant nutrients for sustainable productivity.Vermicompost improves growth, quality and yield of different fi...

Vermicomposting is a mesophilic organic waste management practice in which earthworms interact with the microbiota to drive the stabilization of organic matter. Earthworms influence the microbial populations both directly and indirectly through grazing, ingestion and digestion of organic matter and deposition of castings and modifications of the physico-chemical parameters of the substrate. Under continuous operations, distinct patterns in the dynamics of pH, organic carbon, total nitrogen, total and labile sugars content of the vermicompost were distinguished. At the beginning, there was an a...

E. eugeniae is an ideal species in reducing heavy metals during vermicomposting of flyash and tissue and worm biomass and maximum reduction in vermicasts and accumulation of heavy metals in the tissues.

It appears that incorporation of 1-mon-old vermicompost at 1% to field soils will lower existing reniform nematode population density.

The conventional aerobic and physicochemical treatment processes adopted for treatment of municipal and industrial wastewater in the developed countries have sparse chances of success in developing countries due to high energy requirements, operation and maintenance costs, and constraints in stable maintenance. Thus, it has become imperative to resort to simpler alternative technologies which are natural, less mechanized and simpler in operation and maintenance. Vermiculture appears to be an innovative sustainable technology for waste treatment which holds a promising future in the field of wa...

Rumen content is a waste produced in slaughterhouses. This type of solid waste can cause bad odor and atmospheric pollution if discharged directly into the environment. Additionally, it may spread disease due to the nesting vectors, and the resulting leachate can lead to groundwater contamination. The objective of this study was to determine the suitability of rumen content, waste generated in the slaughterhouse of Villapinzón (Cundinamarca), as raw material for biological transformation into vermicompost at the Fertisoluciones facilities. The characteristics of the rumen content were analyzed...

Vermicomposting offers an eco-friendly solution to managing the sewage sludge generated in wastewater treatment plants. The objective of this study was to investigate the microbial community composition, structure and functionality during the vermicomposting of sewage sludge. We analyzed samples of sewage sludge, earthworm casts and vermicompost by applying high-throughput sequencing 16S and ITS rRNA. Most of the bacterial (95%) and fungal taxa (99%) were eliminated and subsequently replaced by other microbial taxa originating from earthworms. Further changes resulted in a vermicompost with a ...
