“…Manna et al 34 found that continuous increases in worm ( P. excavatus ) population in city garbage might have been due to the suitability of this material and that the C/N ratio of vermicompost (after 180 days) was significantly influenced by the inoculation of earthworms in city garbage as compared with chicken pea straw, soybean straw and wheat straw. In general, Lodha35 found that a better quality of compost from MSW could be generated using the vermicomposting technique. Kaviraj and Sharma36 also found that earthworms were able to vermicompost local MSW, with the maximum carbon reduction being achieved by E. fetida (44.3%) and L. mauritii (44.1%) after 42 days of vermicomposting.…”

There is an urgent need globally to find alternative sustainable steps to treat municipal solid wastes (MSW) originated from mismanagement of urban wastes with increasing disposal cost. Furthermore, a conglomeration of ever-increasing population and consumerist lifestyle is contributing towards the generation of more MSW. In this context, vermicomposting offers excellent potential to promote safe, hygienic and sustainable management of biodegradable MSW. It has been demonstrated that, through vermicomposting, MSW such as city garbage, household and kitchen wastes, vegetable wastes, paper wastes, human faeces and others could be sustainably transformed into organic fertiliser or vermicompost that provides great benefits to agricultural soil and plants. Generally, earthworms are sensitive to their environment and require temperature, moisture content, pH and sometimes ventilation at proper levels for the optimum vermicomposting process. Apart from setting the optimum operational conditions for the vermicomposting process, other approaches such as pre-composting, inoculating micro-organisms into MSW and redesigning the conventional vermireactor could be introduced to further enhance the vermicomposting of MSW. Thus the present mini-review discusses the potential of introducing vermicomposting in MSW management, the benefits of vermicomposted MSW to plants, suggestions on how to enhance the vermicomposting of MSW as well as risk management in the vermicomposting of MSW.

“…Previously, it is reported that the biological treatment is successful technology for the remediation of various types of environmental contaminants (Lodha, 2007;Lodha and Chaudhari, 2007). Recently, the emerging potential research of biotechnology is bioleaching (Chaudhary, 2004).…”

The waste tailing of metals generated during mining processes is degrading the environment by increasing the soil toxicity, leading to disturbances in the ecosystem. This study was initiated to determine the biokinetics of Thiobacillus thiooxidans for manganese bioleaching in the presence of excess sulphur. In batch studies, the effect of manganese concentration on the leaching efficiency of T. thiooxidans was also evaluated, and it was found that as the concentration of manganese increases, the leaching efficiency decreases. This may be due to an inhibitory effect of manganese at higher concentrations. The maximum leaching efficiency of more than 95% was found at lower manganese concentration of 5-25 mg/litre, while the efficiency significantly decreases to 35% at 200 mg/litre manganese. The biokinetic coefficient (maximum growth rate and inhibition constant) was also determined for T. thiooxidans for manganese bioleaching using Haldane's equation. A linear mathematical relationship was also developed between leaching efficiency, initial manganese concentration and time of incubation, which would be useful in predicting the leaching efficiency under various conditions. The significance test using T-paired test was also performed, and it was found that the theoretical leaching efficiency is above 95% confidence level from observed leaching efficiency. The above parameters are invariably required for the design and simulation of batch and continuous bioreactors for bioleaching of manganese tailings. The present work may be useful for management of tailing waste generated during mining processes.

The management of solid waste has become a major problem even in rural areas of India, due to shrinkage of agricultural land and depletion of forest areas. During the recent past, people in rural areas were decomposing the waste, and finally, it was used as a manure in their agricultural areas. However, the trend is completely changing the Indian scenario of converting the backyard waste into manure. Now with the help of scientific knowledge, the waste is utilized as an energy resource, and waste from the rural areas is considered a raw material for this process. Different technologies in India are available to convert waste into energy apart from the technologies that have impact on the environment.
