“…The stock culture of the earthworm was maintained in plastic containers using partially decomposed mixture of bio-waste as a growth medium under laboratory conditions (26 ± 2°C) for further use during the vermicomposting. In the present study, a slight modification in vermireactor was made as compared to reported vermireactor (Gajalakshmi et al 2005;Jain et al 2003), in which pebbles were used as a bedding material in place of cloth to facilitate good drainage.…”

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.

“…Thus it can be carried out indoors or in cellars and on several scales and be adapted for domestic use (Sherman and Appelhof 2011;Pirsaheb et al 2013). It can also be adapted for collective use or on platforms ranging from "low-tech" in windrows (Edwards 2011a;Hanc et al 2017) to "high-tech" in industrial scale vermicomposters (Jain et al 2003;Gajalakshmi et al 2005;Edwards 2011b). Unlike collective vermicomposters, which aim to recycle waste close to where people produce it (e.g.…”

Continued population growth and urbanization as well as changing consumption patterns have led to an explosion in the amount of waste produced, especially in cities. To feed the world, we also need to increase agricultural production while limiting our impact on the environment. Part of the solution could be to recycle the organic fraction of municipal solid waste (OFMSW) as a resource for agriculture near cities with techniques such as vermicomposting, which uses earthworms to recycle organic waste into nutrient-rich vermicompost. The objective of this review was to examine (i) whether vermicomposting is appropriate for recycling OFMSW, (ii) the quality of the vermicompost produced, and (iii) the impact of this product on crops and soil parameters. We found that vermicomposting can be adapted for OFMSW recovery because the process is suitable for all the types of OFMSW (food, paper, and green waste). The vermicompost produced is both high in organic carbon (18.83% to 36.01%) and a potential fertilizer (1.16 to 2.58% N, 0.42% to 1.12% P and 0.61% to 2.05% K). A comparison with compost from the same types of OFMSW suggested that vermicompost is slightly more suitable for crop production with significantly lower C/N and pH and higher N and P. Vermicompost was actually found to have a better effect on plant growth than compost, suggesting that classical chemical analyses are not always sufficient to characterize the potential of organic amendments/fertilizers. Indeed, the application of vermicompost in the field leads to an increase in carbon storage, water retention, enzymatic and microbiological activity, and soil fauna abundance and diversity. Finally, we found that reports on the use of vermicompost from OFMSW are scarce and most studies focused on the process itself. Overall, our review synthesizes data and the interest in this technique and proposes perspectives for future studies.

“…(0% vermicast), while 49.24% of vermicast was produced with the application of Pheretima sp for 28 days of vermibed vermicasting process. In addition to composition and quality, moisture and aeration of vermibed, productivity of vermicast from a vermireactor was also highly determined by the ratio of surface area and volume of vermibed (Jain et al 2003).…”

Earthworms as ecosystem engineers can modify the quality of vermibed assembled from mixed soil with organic material in a vermireactor. Various in shapes of the vermireactor are used to produce a vermicast for biofertilizer in agriculture. The objective of this research was to study the vermicast production and its quality produced from a variety of vermireactor shapes. Earthworm (Pheretima sp.) which was applied to the vermireactor consists of: with- and without of earthworms. Three shapes of the vermireactor, namely cylinder, square, and rectangular has been tested. Compost of Chromolaena odorata pruning mixed with soil was used as vermibed. The vermicast process ran until 28 days. The results showed that vermireactor with earthworms which were successfully converted to vermicast was about 49.24% from the vermibed volume, however, no vermicast formed was found from vermireactor without earthworms. The difference in vermicast produced from different vermireactor shapes was not significant. The value of pH, total-N, and C/N ratio among the vermicast was different. The number of the morphological character of bacteria colonies in the vermicast produced from the square vermireactor was the highest, while from cylinder vermireactor was the lowest. We concluded that the quality of vermicast from earthworm (Pheretima sp.) activity was determined by the shape of the vermireactor.
