  • Biological Monitoring Tools for Recycling Hazardous Effluents

     Abstract Increasing dependence on chemicals and rapid developments in chemical technology have practically triggered the growth of chemical industries in India. Globally, Basel convention guidelines are available for transboundary movement of hazardous wastes. However, at the national levels, health damage, resources losses and ecological impairment due to hazardous wastes indiscriminate ...


  • Minimisation of Hazardous Waste: Bayer Formulation Plant

     Background Bayer Australia Limited formulates agricultural and veterinary products for the Australian and New Zealand markets at their Wyong Formulation Plant in NSW. Due to the nature of the materials the company has adopted a vigorous approach towards monitoring the quality and minimising the quantity of the waste it generates. In January 1992 the company launched a waste ...


  • Turning biological waste treatment plant sludge into a fuel source

    North Carolina, as part of its landfill regulations, banned all waste treatment plant sludges from general landfills in March, 1989. Cranston Print Works Company was producing approximately 20 tons per day of 18% solid non-hazardous sludge in its extended aeration activated sludge waste treatment plant. Sludge disposal costs were $10,000 per week after the ban took effect. This paper traces the ...

  • Anaerobic digestion as integrated part of a mechanical-biological Waste treatment process

    Anaerobic digestion as a means of stabilising residual municipal solid waste (RMSW) before landfilling was evaluated to study the stabilization of RMSW through mechanical-biological processes and evaluate the effect on landfills. The tests were at the site of WGV Recycling GmbH in Quarzbichl between September 1995 and March 1996. The trials, which were run with a single-phase anaerobic digester, ...

  • Mitsubishi corporation - Spent Potliner (SPL) hazardous waste treatment case study

    The Challenge Spent Potliner (SPL) is generated in the primary production of aluminium and worldwide is estimated to rise at a rate of over 500,000 tonnes per year. The SPL waste contains concentrations of cyanide and fluoride and gives off noxious and flammable gases when in contact with moisture. Unless carefully handled, these contaminants readily "leach" into the surrounding soils and ...

  • Decomposition of major organic components during mechanical-biological pretreatment of residual municipal solid waste

    Landfilling of untreated municipal solid waste (MSW) generates environmentally hazardous gas and leachate emissions (El-Fadel et al., 1997). The aim of mechanical-biological waste pretreatment (MBP) is to anticipate this process in a controlled system and to avoid later emissions in the landfill (Leikam and Stegmann, 1997). Main source of these emissions is the microbial metabolism of the easily ...

  • Waste Treatment

    Introduction The Department of Energy's (DOE) Waste Management program directs the storage, treatment, and disposal of waste generated by DOE's activities. In support of this mission, the Waste Management program uses a variety of treatment technologies to change the characteristics of the waste so that it may be more easily managed. What Is Waste Treatment? ...


  • Methodology for conducting screening-level ecological risk assessments for hazardous waste sites. Part II: grouping ecological components

    Screening-level ecological risk assessments are commonly conducted to identify those contaminants and receptors on which to focus future phases or tiers of the ecological risk assessment process. Most screening assessments are performed using a suite of individual species subjected to intensive evaluation of exposure (endpoint species) and selected for their appropriateness for serving as ...

  • Dynatec Provides MBR System for Hazardous Landfill

    The Problem A hazardous waste landfill in Belleville, MI, owned by the Environmental Quality Company had a problem. They needed to develop a treatment process to remove COD, high TDS, heavy metals, phenol, PCB’s, Ammonia, and Molybdenum from the landfill leachate. Current treatment comprised of chlorination and activated carbon treatment was very costly. ...

  • Environmental Sensors in Waste Management

    Issue: As part of an increasing sentiment among European consumers that environmental protection is important, concern about the impact of landfill is growing. Sensor technology makes it possible to measure and control inputs to landfill sites and pollutants arising from them. However, the exploitation - or uptake - of such technology has been lower than expected in the waste management sector. ...


  • Depth of the biologically active zone in upland habitats at the Hanford Site, Washington: Implications for remediation and ecological risk management

    Soil invertebrates, mammals, and plants penetrate and exploit the surface soil layer (i.e., the biologically active zone) to varying depths. As the U.S. Department of Energy remediates radioactive and hazardous wastes in soil at the Hanford Site, a site‐specific definition of the biologically active zone is needed to identify the depth to which remedial actions should be taken to protect the ...

  • Review on hospital wastes and its possible treatments

    Medical waste management is of a great importance due to its potential impact to environment and consequently to human health. In the recent years, many efforts have been made by environmental regulatory agencies and waste generators to better managing the wastes from healthcare facilities. In the past, medical waste was often mixed with municipal solid waste and disposed in residential waste ...

  • Prioritization of pharmaceuticals for potential environmental hazard through leveraging a large scale mammalian pharmacological dataset

    The potential for pharmaceuticals in the environment to cause adverse ecological effects is of increasing concern. Given the thousands of active pharmaceutical ingredients (APIs) which can enter the aquatic environment through human and/or animal (e.g., livestock) waste, a current challenge in aquatic toxicology is identifying those that pose the greatest risk. Because empirical toxicity ...
