Vermiculture is the culture of earthworms. The goal is to continually increase the number of worms in order to obtain a sustainable harvest. The worms are either used to expand a vermicomposting operation or sold to customers who use them for the same or other purposes. Vermicomposting is the process by which worms are used to convert organic materials (usually wastes) into a humus-like materia...

In the present study, initial vermicomposting trials were conducted for 100 days using leaf litters of Polyalthia longifolia (LPL) and sugarcane trash (SCT), each in combination with pressmud (PM) (i.e., 0:100, 25:75, 50:50, 75:25 and 100:0) by inoculating an epigeic earthworm, Perionyx ceylanensis. Based on C/N ratio, worm biomass and numbers recorded in vermicomposting trials, organic substra...

Large areas of land are needed to dispose of wastes produced by mining activities worldwide which poses a myriad of environmental hazards with regards to soil, water and air contamination. This is a problem, especially for a mining country like South Africa, where more than 1500 mines are registered which affects 0.2 million ha of land. Legislation in this country do, however, stipulate that di...

Transformation of industrial sludges into vermicompost is of double interest: on the one hand, a waste is converted into value added product, and, on the other, it controls a pollutant that is a consequence of increasing industrialization. This paper reports the feasibility of utilization of vermicomposting technology for nutrient recovery from industrial sludge in laboratory scale experiment e...

Vermicomposting of organic waste has an important part to play in integrated management strategy. The aim the present study was investigate ability epigeic earthworm Eisenia foetida transform anaerobically digested sewage sludge (SS) amended with hazelnut husk (HH) and cow manure (CM) different proportions under laboratory condition (in darkness at 25°C0,5 0C). Two approaches investigated were...

India produces around 3000 million tones of organic waste annually. This huge volume of waste(s) comes from agriculture, urban and industrial sources and also from domestic activities. Utilization of this waste material for productivity process is important for both economical and environmental reasons. In the present study an effort has been made to asses the efficacy of E. foetida (red tiger ...

Efforts have been made in this study to stabilize the sewage sludge mixed with sugarcane trash in four different proportions: 20% (T(1)); 40% (T(2)); 60% (T(3)) and 80% (T(4)), under laboratory conditions using epigeic earthworm (Oligochaeta) Eisenia fetida. The composting potential of worm was also evaluated in 100% sewage sludge treatment (T(5)). The changes in chemical properties of substrat...
