    ABSTRACT: Municipal solid waste contains high amounts of cellulose, which is an ideal organic waste for the growth of most of microorganism as well as composting by potential microbes. In the present study, Congo red test was performed for screening of microorganism, and, after selecting a potential strains, it was further used for biodegradation of organic municipal solid waste. Forty nine out of the 250 different microbes tested (165 belong to fungi and 85 to bacteria) produced cellulase enzyme and among these Trichoderma viride was found to be a potential strain in the secondary screening. During the biodegradation of organic waste, after 60 days, the average weight losses were 20.10% in the plates and 33.35% in the piles. There was an increase in pH until 20 days. pH however, stabilized after 30 days in the piles. Temperature also stabilized as the composting process progressed in the piles. The high temperature continued until 30 days of decomposition, after which the temperature dropped to 40 ° C and below during the maturation. Good quality compost was obtained in 60 days.

    ABSTRACT: The main purpose of this study is to reduce the production cost of cellulase by optimizing the production medium and using an alternative carbon source such as municipal solid waste residue. In the present investigation, we aim to isolate the two novel cellulase producing fungi (Aspergillus niger and Trichoderma sp.) from municipal solid waste. Municipal solid waste residue (4-5% (w/v)) and peptone and yeast extract (1.0% (w/v)) were found to be the best combination of carbon and nitrogen sources for the production of cellulase by A. niger and Trichoderma sp. Optimum temperature and pH of the medium for the cellulase production by A. niger were 40°C and 6-7, whereas those for the production of cellulase by Trichoderma sp. were 45°C and 6.5. Cellulase production from A. niger and Trichoderma sp. can be an advantage as the enzyme production rate is normally higher as compared to other fungi.

    ABSTRACT: Studies were conducted at Regional office, Madhya Pradesh pollution Control Board and ani Durgavati University to evaluate the quality of municipal and agricultural waste under aerobic and anaerobic composting. Composting methods with enrichment techniques were adopted with two methods (Aerobic and Anaerobic) and seven treatments in each method. The samples of the aerobic were drawn after 0, 10, 20, 30 and 40 days after composting and in anaerobic compost samples were drawn after 50 days of compost. Effect of bio-inorganic carbonulum (Fungal Consortium), chemical amendments (2% P2O5 and 1% N) and method of composting on organic carbon, C/N ratio, pH, EC and total nutrient status during composting was determined in aerobic and anaerobic composts. The organic carbon, C/N ratio decreased significantly during maturation of the compost irrespective of treatments and method of composting. High organic carbon was recorded in 100% urban solid waste (USW) compost in both the methods. It ranged from 20.15% to 24.0% in aerobic matured compost and from 21.5 to 23.25 in anaerobic matured compost. 100% agricultural waste (AW) compost had lower C:N ratio 18.65 and 17.47 in aerobic and anaerobic composts, respectively than 100% USW compost (19.20 to 18.02 in aerobic and anaerobic compost, respectively). Where as the nitrogen content was increased from 0.78% to 1.29% in 100% urban waste compost and 0.75% to 1.23% in 100% agricultural compost. R organic carbon k phosphate treated composts in both methods enhanced the total P content with maximum of 0.89% in both aerobic and anaerobic composts. There was gradual increase of total potassium content from initial status of 0.44 to 0.64%.

    ABSTRACT: Co-processing in cement kiln perforce provides high temperature and long residence condition during the operation and is an effective technology for the management of waste in an environmentally friendly and safe manner. It fully absorbs the energy and material value of the waste without any harmful emissions. Co-processing in cement kiln, ranks higher in the waste management hierarchy, when compared to other disposal options such as incineration and landfill. Unlike incineration and landfill, co-processing does not leave behind any residue that might have harmful impacts on the environment. Thus, co-processing is an ecologically sustainable solution for waste management. Coca-Cola, the corporate nourishing the global community with the worlds largest selling soft drink concentrates since 1886, returned to India in 1993 after a gap of 16 years giving a new thumbs up to the Indian Soft Drink Market. The vision of the company is to lead beverage revolution in the world and provide it's consumer quality beverages at affordable price. The co-processing trial run results concluded that the waste material, namely, ETP Bio Solid, can be safely co-processed in cement kilns. The co-processing technology can provide a better, economically and ecologically more sustainable solution to industrial waste management problem. The trial burn of ETP Bio Solid waste has shown that it can be co-processed/disposed regularly in cement kiln without any adverse impact on process, quality and emissions.

    ABSTRACT: Co-processing in a cement kiln is an effective, environmentally friendly and safe technology for the management of hazardous waste, such as paint sludge, because the cement process perforce provides the high temperature and long residence condition required for the complete destruction of the waste. Furthermore, it fully absorbs the energy and material value of the waste without any harmful emissions. Co-processing in cement kilns ranks higher in the waste management hierarchy when compared to other disposal options, such as incineration and landfill. Co-processing is unlike incineration and landfill processing, which leave behind residue that might have harmful impacts on the environment. Thus, co-processing of paint sludge is the best option for an ecologically sustainable solution for paint sludge waste management. The co-processing trial of paint sludge was carried out by Associated Cement Companies (ACC) under the guidance of Karnataka state pollution control board (KSPCB), in the presence of a Toyota Kirloskar Motors Limited (TKML) representative from 8th to 17th April 2008. The trial carried out had three phases, namely pre co-processing, co-processing and post co-processing. The parameters, such as dioxins and furans, total organic carbon (TOC), poly aromatic hydrocarbon (PAH), particulate matter (dust), Co2, Co, O2, NOx, So2, HCl, HF, HBr, NH3, C6H6 and heavy metal (Hg, Sb, As, Cd, Cr, Co, Cu, Pb, Mn, Ni, Ti, V) emissions, were monitored from the kiln stack during each phase of the co-processing trial. The co-processing trial run results concluded that the waste material, namely paint sludge, can be safely co-processed in cement kilns. Keywords: paint sludge waste, co-processing, pyrolysis, landfill, incineration, emissions.

    ABSTRACT: Currently, Rapid industrialization and Population explosion in India, the estimated quantity of the waste generation was11 billion tones of industrial wastes and 1.6 billion tones were municipal solid waste. About 90 billion tones solid wastes are expected to be generated annually by the year 2025. The main objective of this study is to maximize economic benefits and at the same time protection of environment by microbial activity for waste management. Cellulases are group of hydrolytic enzymes capable of hydrolyzing the most abundant organic polymer i.e. Cellulose to smaller sugar components including glucose subunits. Cellulases have enormous potential in industrials and used in food, beverages, textile, laundry, paper and pulp industries etc. This study was aimed to screen the cellulolytic ability of fungi from municipal solid waste. Out of 20 fungal culture isolates from environmental sources including 8 different zones, 16 fungi were found to passes cellulose degrading ability. Cellulolytic fungi belonging to Aspergillus funmigatus, Trichoderma sp.I and Chaetomium sp. Results obtained during this study clearly indicate that cellulase activity of Aspergillus fumigatus and Trichoderna sp.1 were found relatively towards the higher side and A. niger, A. flavus, A. nidulans, Alernaria sp., Penicillium sp. moderate range while Fusarium sp., Humicola sp. and Torula sp. showed low cellulase activity. These fungi were potential cellulose degrader and useful for the management of municipal solid waste.

    ABSTRACT: Inhibitions of seed germination and plant injuries have been reported following the application of fresh or partially composted wastes to soil. However, effective test determining compost biomaturity after storage is on a trial and error basis. An incubation experiment and a pot experiment were conducted to investigate the decomposition, transformation and optimal application rate of compost, which was prepared from municipal solids waste. The compost showed inhibition of seed germination using aqueous extract of the compost when compared with distilled water or mature compost for their effect on germination and root development of Zea maize L. The germination index (G.I.) and the ratio of optical densities at 465nm and 665nm (E4/E6) of dilute aqueous extract were used to show the time required for municipal solid waste compost reaching its biomaturity. The E4/E6 ratio increased with time and then decreased after 30 days of decomposition. This decrease was linked with biomaturity and stabilization stage of the fresh compost, as observed with a decrease in inhibition effect on seed germination. With reference to the period of maturity of the compost, MSW compost was incorporated in to pots with sandy soil at different ratio of application three different ratio 25:75, 50:50, 75:25 and 100% compost. The results showed significant effects on plant height and dry mater yield. The optimal ratio of application was 50:50.
