  • 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 ...

  • 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 ...

  • Project proposal & documentation for solid waste management (SWM) & production of the organic compost from municipal and household waste in Mannar district – Sri Lanka

    1.1. Brief Description of Problem Statement The organic solid waste has to be produced from Mannar Town in about 12 M.T per day. The higher amount of inorganic fertilizer using in Mannar District and the demand of fertilizer also is high. Our production of organic fertilizer can replace the inorganic fertilizer and we believe the positive environmental impact is expected and may increase the ...


  • Measuring solid waste eco-efficiency performance through environmental accounting

    Planning and implementation of eco-efficient practices require different information measured both in financial and non-financial units. Indeed, eco-efficiency strategies, by definition, require this type of information to simultaneously confirm the reduction of the total amount of solid waste production and the improvement in organizations' added value. However, current solid waste accounting ...

  • On the pre–treatment of municipal organic waste towards fuel production: a review

    Lignocelluloses are the main constituents of municipal organic waste (MOW). In order to increase the production of fuels, via fermentations, the enzymatic hydrolysis is the first step towards a valorisation process. It is well–known that the hydrolysis of lignocelluloses is not very effective because of the high stability of the constituents. In this respect the pre–treatment of MOW is necessary ...

  • Composting cotton industry by-products. Evaluation of Use of cotton solid wastes compost as a substrate.

    The textile industry at region of Entre Douro e Minho is located at Ave valley and is responsible for a great amount of cotton solid wastes. Currently these wastes, which are characterised by a high C/N ratio and some salinity, are directly applied to soil by farmers without any previous treatment (Zucconi et al, 1981). Extraction of peat causes environmental damage (Smith, 1992) which leads to ...

  • Use of stratified cluster sampling for efficient estimation of solid waste generation at household level

    Relatively few studies have been performed to characterize municipal solid waste (MSW) at household level. This is due in part to the difficulties involved with collecting the data and selecting an appropriate statistical sample size. The previous studies identified in this paper have used statistical tools appropriate for analysing data collected at a material recovery facility or landfill site. ...

  • Acidogenic fermentation of municipal solid waste and its application to bio-electricity production via microbial fuel cells (MFCs)

    Acidogenic fermentation of organic municipal solid waste (MSW) and the bio-electricity production potential from its volatile fatty acid (VFA)-rich leachate using an air-cathode microbial fuel cell (MFC) was investigated in this study. The acidogenic fermentation of 2 kg of MSW has been carried out in a 6 L anaerobic leach-bed reactor (LBR) under mesophilic conditions (30 °C). Total production of ...

  • Improved methane production from waste activated sludge with low organic content by alkaline pretreatment at pH 10

    Sludge with low organic content always results in an unsatisfactory performance, even failure of anaerobic digestion. The alkaline pretreatment effect on anaerobic digestion of sludge with low organic content has seldom been studied although it gives many benefits for sludge with high organic content. In this study the influence of alkaline pretreatment (pH 10, an effective alkaline pH) on the ...

  • Turning waste into power

    Economic, social and environmental factors dictate the necessity to manage waste to a new level. Wastewater plants, landfills, farms and food plants are all the owners of biomass that can be digested to produce biogas and turned into power. Biogas can be burned directly in boilers for heat recovery and used for manufacturing, heating or cooling; this is the simplest method of direct biogas ...

  • Waste Management Overview

    Introduction Our Nation has entered an era in which, as a result of changing world conditions, nuclear weapons production is receiving less attention while the public is expressing increasing concern about protecting human health and preserving the quality of our environment. In response to this national concern, the Department of Energy (DOE) has made waste cleanup and environmental restoration ...

  • Waste Minimisation Strategies: Halls of Residence

     The University of Wollongong (UOW) has six accommodation sites - four Halls of Residence and two Colleges. Waste minimisation strategies have been introduced by the Four Halls of Residence to comply with their commitment to the aims and outcomes of the NSW Waste Minimisation and Management Act 1995 to reduce waste to landfill to 60% by the year 2000. By focusing on the kitchen waste stream, ...


  • Closing the Waste Loops: Australian Newsprint Mills

     The manufacture of newsprint is a process which generates both solid and liquid wastes. Australian Newsprint Mills Ltd Albury has given increasing attention to waste issues in recent years and has succeeded in closing or partially closing some of the ëwaste loopsí, especially in the areas of waste paper recycling, waste water, and solid waste. Background Australian ...


  • Making India`s waste streams sustainable

    MIT researchers are developing a decision-support tool to help cities in India sustainably manage the societal and environmental impacts of their waste. The massive Deonar dumping ground in Mumbai has become the most visible emblem of an increasingly serious nationwide problem for India: what to do with its trash. Deonar’s towers of garbage are ...

  • Axion: is ‘storing’ waste plastics better than burning?

    As global temperatures head for potentially catastrophic levels, landfilling rather than burning waste plastics might be better for the environment, suggests Keith Freegard, Director of Axion Polymers. Landfill or incineration: what is the best disposal route for our waste plastic materials? Large numbers of energy-from-waste (EfW) plants exist right across Europe and many of ...

  • How Food Waste Costs Our Cities Millions

    It would take farm land the size of Mexico just to grow the amount of food that humans produce, but do not eat, every year. More food goes uneaten at the consumption phase of the supply chain—in places like homes, restaurants and cafeterias—than at any other stage. Almost all urban areas experience high levels of food waste—food that is fit for consumption when it reaches ...

  • Comparing Capacity Expansion and Waste Minimization Options at a Chemical Manufacturing Facility

    ABSTRACTIndustrial wastewater treatment facilities that are nearing their capacity limit often have a relief option that typically is not available to municipal treatment facilities. That option is to reduce waste loads coming from the production areas by optimizing manufacturing processes so that less waste is generated per pound of product made. In making the decision between reducing waste ...
