Earthworms and vermicomposting
نویسندگان
چکیده
A review is presented summarizing the global state-of-the-art, including the gist of the studies conducted by the authors, on vermicomposting. Studies on the impact of vermicast on plant growth are also reviewed. The paper brings out the suitability or otherwise of different species of earthworms to ‘bioprocess’ different types of organic waste. The paper also presents the gist of the studies–which are surprisingly few and far between–on the impact on plant growth of vermicasts produced in reactors fed with aquatic weeds or agrowaste.

Vermicomposting of Solid Waste Using Local and Exotic Earthworms: A Comparative Study.
The aim of this study was to assess the decomposition efficiency of earthworms, local (L.mauritii) as well as exotic (Eisenia foetida) in vermicomposting of garden litter in SRM University campus. The vermicompost produced through vermicomposting of garden litter mixed with cow dung in the ratio of 3:1 by using local and exotic earthworms (Eisenia foetida) was rich in ammoniacal nitrogen, nitra...
متن کاملMunicipal solid waste management through vermicomposting employing exotic and local species of earthworms.
A comparative study was conducted between exotic and local (epigeic--Eisenia fetida and anaecic--Lempito mauritii, respectively) species of earthworms for the evaluation of their efficacy in vermicomposting of municipal solid waste (MSW). Vermicomposting of MSW for 42 days resulted in significant difference between the two species in their performance measured as loss in total organic carbon, c...
متن کاملQualitative analysis of the stability of a continuous vermicomposting system.
A mathematical model was established to describe ecological relationships in a continuous vermicomposting system. The distributions of organic matter, microbes and earthworms on non-dimensional specific growth rates were simulated. The range of specific growth rates were visualized utilizing three-dimensional reconstruction technology. The stability of a vermicomposting system was not influence...
متن کاملIntegrating composting and vermicomposting in the treatment and bioconversion of biosolids.
Traditional thermophilic composting is commonly adopted for treatment of organic wastes or for production of organic/natural fertilizers. A related technique, called vermicomposting (using earthworms to breakdown the organic wastes) is also becoming popular. These two techniques have their inherent advantages and disadvantages. The integrated approach suggested in this study borrows pertinent a...
متن کاملPilot-scale vermicomposting of pineapple wastes with earthworms native to Accra, Ghana.
Pineapple wastes, an abundant organic waste in Accra, Ghana, were vermicomposted using native earthworms (Eudrilus eugeniae Kinberg) collected from the banks of streams and around bath houses of this city. Triplicate pilot-scale vermidigesters containing about 90 earthworms and three other control boxes with no earthworms were fed pineapple pulp or peels, and the loss of wet mass was monitored ...
