Municipal solid wastes are mainly from domestic and commercial areas containing recyclable toxic substances, compostable organic matter and others. With rapid increase in population, the generation of municipal solid wastes has increased several folds during last few years. Disposal of solid wastes can be done by methods like land filling, incineration, recycling, conversion into biogas, disposal into sea and composting. Vermicomposting is one of the recycling technologies which will improve the quality of the products. The present study aims to find out the possibility of utilization of vegetable wastes for vermiculture. EarthwormMegascolex mauritiicultured in plastic trays (45 x 30 x 30 cm) containing soil alone (control) (T1), soil + cow dung (T2), soil + vegetable waste (T3) and soil + vegetable waste + cow dung (T4) for 60 days. Nutrient values were determined from the compost and compared with that of the control. From these results, it was found that NPK values were maximum in compost obtained from vegetable waste with the use of cow dung.

Abstract Researches on the use of waste vegetable (tomatoes, peppers) and fruits (apples, plums) in order to improve the nutritional quality of the soil have been performed. The content in nitrogen, phosphorus, potassium, humus, organic matter have been analyzed in fruits and vegetable waste and also in soil before and after mixing with each waste at a ratio of 1:2.5. Analyses were done by using current analytical methods (chemical and absorption molecular spectrometry) after previous mineralization of samples with appropriate reagents. To investigate the effect of vegetable wastes on the plants growth, wheat has been planted in the witness soil sample and in the mixed soil with wastes. The nutrients concentration in vegetable waste was higher than in fruit waste (33-75%). Available phosphorus concentration increased about two times in soil with fruit waste while in the soil with vegetable the increase was of about 3 times. Potassium concentration increased about three times in soil mixed with both types of waste. Although potassium and organic matter have higher values in the soil amended with fruit waste than in the witness soil, the height of the wheat was similar with those in the control soil due to the limiting role of phosphorus.

The Municipal Solid Waste of Agareb (Sfax –Tunisia), characterized by high organic fraction and moisture contents is the most worrying pollution source that must be managed by innovative treatment and recycling technologies. Bio-drying, as a waste to energy conversion technology, aims at reducing moisture content of this organic matter. This concept,  similar to composting, is accomplished by using the heat generated from the microbial degradation of the waste matrix, while forced aeration is used. The purpose of this work was to reduce the moisture content of the waste, by maximizing drying and minimizing organic matter biodegradation, in order to produce a solid recovered fuel with high calorific value.Keywords: Municipal solid wastes; organic matter; biodrying; composting; energy recovery.

In order to study the effect of Tehran municipal solid wastes compost on manganese accumulation in soil and to determine its concentration in any readily available plant forms (exchangeable and carbonates-bonded), Mn-oxides bonded fraction, organic matter bonded fraction, and residual fraction in a calcareous soil, a factorial experiment based on completely randomized block design (RCBD) was conducted in research field of Shahed university at different levels of municipal solid wastes compost (0, 15, 30, and 60 ton/ha) as first factor and application times (one- or two-year compost application) as second factor in three replications. Results showed that, by increasing compost level, total Mn concentration, DTPA-extractable concentration, and amounts existing in all five fractions were increased, so lowest and highest amounts of Mn were observed in control and 60 ton/ha compost application. Based on results from Mn fractionation using Tessier consecutive extraction method, Mn fractions in all samples were in the following order: residual > Fe-Mn oxides > carbonates-bonded > organic matter-bonded ≫ exchangeable fractions in which residual fraction (RE) at first and second year was dominant rather than other fractions by 34.28–43.04 and 34.28–49.48 percent, respectively. Mn concentration in Fe-Mn oxides-bonded fraction at both years was considerable. Mn amounts in Fe-Mn oxides- bonded, application times were decreased.

Environmental pollution is the major problems associated with rapid industrialization, urbanization and rise in living standards for people. Gelatin industry solid waste contains plant nutrients and organic matter, which could enhance the availability of nutrients, enrich the soil organic matter and ultimately increase the crop growth. Hence, the study was conducted to convert gelatin industry solid waste with nutrient-rich materials such as cow dung, poultry waste and coir pith with microbial cultures for the production of nutrient-rich value-added manure. Composting of GISW along with coir pith, cow dung and poultry waste recorded the desirable C/N ratio of 12.4:1 and highest nutrient contents (1.85, 3.85 and 1.24% of N, P and K, respectively). Also, the composted gelatin industry solid waste (CGISW) was subjected to various maturity tests and phytotoxicity assay.  The indiscriminate disposal and accumulation of solid wastes generated by gelatin manufacturing industries are the cause for concern. Hence an attempt has been made to convert these gelatin industry solid wastes (GISW) into bio-manure by blending with other organic wastes such as poultry waste, coir pith and cow dung with suitable microorganisms.

Abstract The aim of the study was to assess the transformation of humic substances during composting of biomass of energetic plants and municipal solid waste. The type of the organic material to be composted and the type of technology used affect the course of the humic substances transformation and formation of compost maturity parameters. Compost produced from the mixture of energetic willow and hay biomass contained humic substances with higher share of low-molecular fractions and lower share of humic acids in total organic carbon than those produced from municipal solid wastes. Obtained results also showed that insoluble alkali fraction plays an important role in humification process by its convertion to a new humic substances. Share of humic and fulvic fractions in relation to the total organic carbon appears to be reliable indicator of composting as a process of enhancing organic matter humification.

Cellulase producing bacteria were isolated from cow dung and municipal solid wastes using enrichment technique. Cellulase activity was determined on carboxymethyl cellulose (CMC) agar medium supplemented with 1% CMC. Production of clear zones by the bacterial isolates on CMC agar was considered as indicative of extracellular cellulase activity. The greater size of transparent zone diameter was found proportional to the higher amount of cellulase production. Two bacterial isolates producing significant clear zone were identified as Pseudomonas spp based on morphological, cultural and biochemical characteristics. Fermentation was carried out under shake flask conditions for production of cellulase from Pseudomonas isolates in a basal medium containing CMC, KH2PO4, K2HPO4, MgSO4, NH4SO4, CaCl2 and FeSO4 at pH 7.0. The assay of cellulase viz. endoglucanase and exoglucanase in terms of CMCase and FPase, respectively was done by measuring the release of the reducing sugar. Some parameters influencing the production of cellulase by these bacterial isolates were investigated. Optimum level of cellulase was produced after 48 h of fermentation at 37°C with 5% inoculums size under continuous agitation at 120 rpm in the growth medium of pH 7.0. Optimum temperature and pH for the activity of cellulase from these bacterial isolates was 40°C and 7.0, respectively. Cellulase from these isolates was found almost stable at 25-40°C and pH 6.0-8.0 for 1 h. Furthermore, the cellulase activity was stimulated by Ca2+ and K+ but inhibited by Hg2+ and Zn2+, whereas, Mg2+ showed very low effect. Results reported herein indicated that the Pseudomonas isolates can be used as producer of extracellular cellulase.Bangladesh J Microbiol, Volume 30, Number 1-2,June-Dec 2013, pp 11-16

Earthworms are one of the soil macroorganisms that have a very important role in maintaining soil quality in a sustainable manner. Lumbricus rubellus is one of 1800 types of earthworms that live on the surface of the soil which has the ability to degrade very high organic matter. The quality of vermicompost fertilizer is strongly influenced by the types of media because decaying speed is determined by the C / N ratio. This study aims to determine the type of media that is best used to improve the quality of vermicompost fertilizer. Experiment was used completely randomized blok design in factorial pattern. he first factor is the population of worms consisting of 4 levels (Control, 20 Tails, 40 Tails, and 60 Tails). The second factor is media worms consisting of 4 levels (slurry cattle + 25% straw, slurry pigs + 25% straw, slurry cattle + 25% straw + 25% vegetables waste, slurry pigs + 25% straw + 25% vegetables waste) with three replication so that there are 48 test units. The results showed that the interaction of treatments had a very significant effect on: decay speed, C-organic, population of earthworms, earthworm eggs, total microorganism population, and pH of vermicompost, except P-available and N-total. It can be concluded that the best vermicompost quality in the study was slurry cow + 25% rice straw + vegetable waste and 60 earthworms.

The Impact

Discharging of untreated municipal solid wastes (MSWs) onto land is very widespread in developing countries. The compounds contained in MSW cause a harmful effect to human and environment. Hence, an assessment of the extent of their local impact is of great interest to figure out the pollution they cause. Therefore, this study aimed at evaluating the effects of discharge of solid wastes on soil quality within the landfill of Ain-El-Hammam municipality (Algeria). To achieve this, different soil physicochemical parameters were considered: granulometry, electrical conductivity, pH, organic matter content, and heavy metal concentration. The results indicated the influence of the MSW on the physicochemical characteristics of the soil by enhancing the organic matter content of soil (4.53%) and increasing heavy metal content (Cu, Zn, Cd, Pb, Ni, and Cr), which is a clear indication of the level of pollution they are generating.
