“…As a natural feed for the growth of earthworm Lumbricus rubellus is found in moist organic substrates; animal manure, and sewage solids (Elvira et al 1997). Usually, animal slurry is cited by Garg and Kaushik (2005), Aira and Domínguez (2008) as the most favourable material for feeding of earthworms.…”

Several technologies are being applied for treatment of palm oil mill wastes. Among them, the biological treatments (vermicomposting) have widely been recognized as one of the most efficient and eco-friendly methods for converting organic waste materials into valuable products. The present study focuses on vermicomposting of acidic palm oil mill effluent (POME) mixed with the palm pressed fibre (PPF) which are found difficult to decompose in the environment. The industrial waste (POME) was vermicomposted using Lumbricus rubellus under laboratory conditions for a period of 45 days. A significant improvement in nitrogen, phosphorus, and potassium content was monitored during vermicomposting process. In addition, the decline in C:N ratio of vermicompost (up to 17.20 ± 0.60) reflects the degree of stabilization of POME-PPF mixture. Different percentages of the vermicompost extract obtained from POME-PPF mixture were also examined for the germination of mung bean (Vigna radiata) seed. The results showed that 75% vermicompost extract demonstrated better performance for the seed germination. On the basis of significant findings, POME-PPF mixture can be successfully used as a feeding material for the earthworms, while on the other hand, it can also be used as a cost-effective fertilizer for the germination and the proper growth of mung bean.

“…From the 1990's scientists started using pulp and paper mill sludge also referred as pulpmill solids for vermicomposting as bulking agents [5][6][7][8][9][10]. Vermicomposting of purely pulpmill solids has not been conducted at any significant scale because the wide C/N ratio of pulpmill solids makes this product unsuitable for vermicomposting.…”

The traditional means of disposing of processing waste to landfill is receiving close scrutiny due to high capex and opex costs and negative environmental impacts. Increasingly stringent legislation means communities and industries are seeking the security of alternative solutions when planning their long-term organic waste disposal strategies. Important to these are excellence in environmental performance, ecological sustainability and to cost effectiveness. Vermicomposting technologies achieve this through the conversion of wet organic waste to a nutrient rich, safe fertiliser for sustainable land utilisation.

“…The duration of the active phase depends on the species and density of the earthworms involved (Ndegwa et al 2000;Lazcano et al 2008;Aira et al 2011). A wide range of oganic wastes viz., horticultural residues from processed potatoes (Edwards 1988); mushroom wastes (Edwards 1988;Tajbakhsh et al 2008); horse wastes (Hartenstein et al 1979;Edwards et al 1998); pig wastes (Chan and Griffiths 1988;Reeh 1992); brewery wastes (Butt 1993); sericulture wastes (Gunathilagraj and Ravignanam 1996); municipal sewage sludge (Mitchell et al 1980;Dominguez et al 2000); agricultural residues (Bansal and Kapoor 2000); weeds (Gajalakshmi et al 2001); cattle dung (Gunadi et al 2002); industrial refuse such as paper wastes (Butt 1993;Elvira et al 1995;Gajalakshmi et al 2002); sludge from paper mills and dairy plants (Elvira et al 1997;Banu et al 2001); domestic kitchen wastes (Sinha et al 2002); urban residues and animal wastes (Edwards et al 1985;Edwards 1988) can be vermicomposted (Sharma et al 2005).…”

Vermicomposting is a non-thermophilic, boioxidative process that involves earthworms and associated microbes. This biological organic waste decomposition process yields the biofertilizer namely the vermicompost. Vermicompost is a finely divided, peat like material with high porosity, good aeration, drainage, water holding capacity, microbial activity, excellent nutrient status and buffering capacity thereby resulting the required physiochemical characters congenial for soil fertility and plant growth. Vermicompost enhances soil biodiversity by promoting the beneficial microbes which inturn enhances plant growth directly by production of plant growth-regulating hormones and enzymes and indirectly by controlling plant pathogens, nematodes and other pests, thereby enhancing plant health and minimizing the yield loss. Due to its innate biological, biochemical and physiochemical properties, vermicompost may be used to promote sustainable agriculture and also for the safe management of agricultural, industrial, domestic and hospital wastes which may otherwise pose serious threat to life and environment.
