  • Solid waste routing

    In today’s struggling economy we are all forced to look at ways to reduce expenses. This applies to private and public operations equally. For the private operation, priorities are placed on maintaining profits—a difficult task in a competitive industry. Raising rates is typically met with resistance from customers, as well as opens a door for competitors to move in. For the public ...

  • 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 ...

  • 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 ...

  • Emission of volatile organic compounds from solid waste disposal sites

    The emission of volatile organic compounds (VOCs) from a solid waste disposal site for municipal solid wastes was quantified. The VOCs contained in the landfill gas taken at the site were benzene, toluene, xylenes, ethyl benzenes, and trimethyl benzenes, while the concentrations of chlorinated compounds were very low. The concentration of benzene in the landfill gas samples ranged from below the ...

  • 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 ...

  • Influence of the comminution of organic waste on their biodegradability

    Organic solids are present in very large quantities as products or waste from agriculture, food industry, household and many other fields. The disposal of organic waste can be realised using biological processes like anaerobic digestion or aerobic composting. The anaerobic digestion has advantages in comparison to composting such as a better handling of wet waste, the production of useful ...

  • 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 ...

  • Life Cycle Assessment technique for sound management of organic municipal solid wastes

    Mauritius generates around 1200 tonnes of municipal solid wastes on a daily basis, out of which more than 60% is of organic nature. The objective of this paper was to evaluate two different strategies for the treatment of organic wastes on a life cycle perspective, namely: composting and Anaerobic Digestion (AD). The functional unit was one ton of organic municipal solid wastes. Windrow ...

  • 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 ...

  • Geophysical applications to solid waste analysis

    Abstract: Case studies of regional landfills show that electromagnetic geophysical methods can accurately and inexpensively define boundaries and thickness of waste. Degradation of putrescible solid waste generates conductive leachate that can be imaged with a frequency-domain terrain conductivity meter. Terrain conductivity measurements can be modified through a simple algorithm based upon ...

  • Characterization of solid waste and determination of the emission potential

    Waste samples were taken in order to investigate the material behaviour regarding different treatment/recycling options. In waste incineration, the combustible and inert parts have to be determined. The content of biodegradable organic substances is important in biological treatment. The portion of biodegradable organic substance has also to be considered if wastes are to be landfilled. This ...

  • Effect of co-managing organic waste using municipal wastewater and solid waste treatment systems in megacities

    A model was developed to calculate the mass and heat balances of wastewater and municipal solid waste treatment plants when these plants operate either separately or together with a mutual dependence on mass and energy. Then the energy consumption, life cycle costs (LCCs), greenhouse gas (GHG) emissions and effluent quality were evaluated under various scenarios to identify the most effective ...

  • Treatment of organic wastes in malaysia . Problems and Prospects

    Solid waste is one of the biggest environmental problems in Malaysia (Hassan et al. 1995). The amount generated continues to increase in response to rapid increase in population and accelerated urbanisation and industrialization processes. Immediate and long-term strategies are required to ensure that the country’s rapid economic growth is not achieved at the expense of massive pollution ...

  • Domestic scale vermicomposting for solid waste management

    Background;Vermicomposting has recently been recognized as one of the most appropriate methods to stabilize organic waste. In terms of a system for waste management, vermicomposting is sustainable, economically viable, and without detrimental effects to human health or to the environment. The aim of this study was to evaluate the process of vermicomposting using an indigenous species of ...

  • Treating organic waste with Cambi THP

    ABSTRACT This paper describes how the Cambi Thermal Hydrolysis Process (THP) treats biodegradable organic waste and converts it to renewable energy and pathogen-free and bio-fertilizer. The interest for the process is expected to increase due to new environmental legislation as well as increasing demand for renewable energy. The implementation of the European Landfill Directive 1999/31EC and the ...

  • Biomethanation of solid wastes: analysis of case studies

    Management of the organic fraction of urban solid waste using anaerobic procedures will contribute to the reduction of greenhouse gas emissions, and using biogas, which is a carbon neutral energy, to generate electrical energy will eventually help in reducing the combustion of fossil fuel. Energy recovery in the form of biogas from Municipal Solid Waste (MSW) generated in three different ...

  • 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 ...
