Comparative assessment of anaerobic digestion of municipal solid waste at mesophilic and thermophilic temperatures
Anaerobic digestion is an environmentally sound treatment option for the organic fraction of municipal solid waste (OFMSW) and simultaneously producing methane gas which is a source of renewable energy. The COD reduction of the substrate was 72% for the mesophilic condition and 72.3% for the thermophilic condition. 1200 cm³ of methane was produced in the mesophilic condition and 1260 cm³ in the ...

Effect of microwave temperature, intensity and moisture content on solubilisation of organic fraction of municipal solid waste
High temperature and pressure microwave (MW) pre-treatment of the Organic Fraction of Municipal Solid Waste (OFMSW) enhanced solubilisation prior to Anaerobic Digestion (AD). Three temperatures (175°C, 145°C and 115°C), three MW intensities based on temperature ramp times (20, 40 and 60 minutes) and two Supplemental Water Additions (SWA) of 20% and 30% were evaluated. MW irradiation resulted in ...

Efficiencies of select vector repellents during composting of Municipal Solid Waste
Presently, most preferred mode of treatment of Municipal Solid Wastes (MSW) is composting. However, this may lead to health hazard because of the potential presence of pathogens, and vector borne insects, rodents etc., in the compost. Field studies were undertaken towards use of Folidol (organophosphate) and Celrich (biopesticide) as repellents of vectors while composting of MSW. At 0.05 kg m−2 ...

Extent and rate of biodegradation of different organic components in municipal solid waste
Rates and extent of biodegradability of four different organic components of municipal solid waste (leaf litter, newspaper, magazine paper and A4 sheet) were evaluated under optimum conditions. Total solids (TS) removals in biotic samples ranged from 74.7% to 78.8% while volatile solids removals ranged from 75.7% to 84.8%. Significant biodegradation of tannin–lignin was observed for all four ...

Performance study for anaerobic digestion of municipal solid waste in a single phase reactor
Anaerobic Digestion (AD) has been up to now essentially applied to wastewater. However, anaerobic treatment of organic solid waste fits well with the new requirements for waste management. A batch study of vegetable market waste composed at various solid concentrations was studied in a single phase anaerobic reactor. Prior to this, studies were also carried out in aspirator bottles of different ...

Potential of hydrogen production from organic Urban Solid Waste fermentation in Mexico
Mexico generated 35.4 million tons of urban solid wastes in 2005 of which 51% were organic ones. This biomass can be fermented into H2 when H2-based technologies increase their market penetration for the year 2020. The purpose of this work was to review studies that have utilised organic solid wastes for fermentative H2 production and to evaluate the potential for Mexico. The experimental H2 ...

The mathematical modelling of biomethane production and the growth of methanogenic bacteria in batch reactor systems fed with organic municipal solid waste
A mathematical model was developed and validated for an anaerobic digestion system of the Organic Fraction of Municipal Solid Wastes (OFMSWs) by using a laboratory-scale system of two Packed Bed Reactors (PBRs). The equations were obtained by the mass balances of methanogenic bacteria of affluent and effluent lixiviated, as well as the interior in each reactor. The methane rate was obtained by ...

Management of organic content in municipal solid waste - a case study of Lahore
Poor solid waste management (SWM) is one of the leading obstacles for absolute clean and healthy environment. Growing economy of Lahore has rapidly increased growth rate which in turn has flared solid waste generation. Municipal solid waste is contributing heavily to air, water and land pollution and a major portion of municipal waste is organic. Generally considered unfruitful, this organic ...

Shredder Machine for Municipal Solid Waste
If you need to deal with municipal solid waste, then you need an industrial shredder (usually dual-shaft shredder), which is used to shred the mixed waste stream into small pieces for subsequent processing. There are many treatment methods for municipal solid waste, usually bio-mechanical treatment or mechanical treatment, organic matter is fermented, combustible waste is made into RDF, and metal ...

Evaluation of a sequential aerobic?anaerobic treatment of municipal solid waste in a bioreactor landfill
A sequential aerobic-anaerobic bioreactor landfill was operated and monitored over a period of 184 days. The bioreactor was filled with 120 kg of organic fraction of Municipal Solid Waste. Leachate recirculation was applied. The results showed rapid degradation of organic matter with rapid settlement during the aerobic period. The initial COD and BOD5 were reduced from 46,500 and 41,500 mg/L to ...

Anaerobic fermentation of organic solid wastes: volatile fatty acid production and separation
Anaerobic fermentation of organic municipal solid waste was investigated using a leach-bed reactor (LBR) to assess the volatile fatty acid (VFA) production efficiency. The leachate recycle rate in the LBR affected the VFA composition of the leachate. A six-fold increase in the recycle rate resulted in an increase of the acetic acid fraction of leachate from 24.7 to 43.0%. The separation ...

Dual role of hydrolysis coefficient in modelling of bioreactors
To the authors' knowledge, there is no published work, relating biodegradation and settlement of municipal solid waste (MSW) in bioreactor landfills together. The present mathematical model is developed to simulate the biodegradation of MSW in anaerobic bioreactor landfills and predict the strength of leachate in terms of volatile fatty acid (VFA). The hydrolysis rate constant (kh) has been found ...

Implementation of la21 policies on waste management and the consequences on biotechnology of organic solid waste
The UN 'Earth Summit' in Rio de Janeiro, Brazil, in 1992 came about because of international concern about the environmental impact of human development, especially in areas like water, soil and air pollution, global warming, endangered species, tropical forests and oceans. The 'Rio Summit' produced a document called 'Agenda 21 – A plan for the 21st Century', which was signed and agreed to be ...

In-situ estimation of the methane generation rate for a wet and highly organic solid waste landfill
Significant investments in landfill gas utilisation projects are required at project commencement. The methane generation rate for the Villa Dominico Landfill in Buenos Aires, Argentina is 0.26 yr−1, a very high rate as a result of the high organic content in the waste, and high moisture conditions within the refuse. The implications for landfills is that landfill gas recovery projects must be ...
