  • Cobalt and its compounds

    Abstract Cobalt is a compound that occurs in nature. It occurs in many different chemical forms. Pure cobalt is a steel-gray, shiny, hard metal. Cobalt used in industry is imported or obtained by recycling scrap metal that contains cobalt. It is used to make alloys (mixtures of metals), colored pigments, and as a drier for paint and porcelain enamel used on steel bathroom fixtures, large ...

  • Applying & Testing Waste Management Quick Wins

    Executive Summary This project was to implement and test construction waste recovery Quick Wins (QWs) on several case study projects on behalf of the construction team at the Waste & Resources Action Programme (WRAP), to investigate construction waste streams and analyse the management and disposal process. The aim was to explore a range of possibilities and best practice options available ...

  • Vehicular Emission (Air Quality) Monitoring Study in Lagos, Nigeria

    INTRODUCTION On October 12, 2006 residents around Lagos Metropolis woke up, to their wonderment, to a hazy atmosphere which was very unusual to Lagosians and indeed to so many people. Many were lost as to what was happening. Some schools, especially around ...

  • Dallas Contracting Co., Inc. Completes Demolition Services at Site in New Jersey

    Dallas Contracting Co., Inc. was contracted by a large developer to demolish all structures at a site in New Jersey. The site consisted of a large farm style house, barns and sheds. Demolition contracting services included the demolition and remove all structures, concrete floors, slabs, footings and foundations. Instead of demolishing the one large barn, Dallas Contracting dismantled and ...


  • Sustainable waste cooking oil systems supporting reuse such as Bio-fuels

    Waste cooking oil has great potential to be used as bio-fuel. What is not well known is that oil leaks carry risks of contamination and disease - proper storage is essential. OverviewWaste cooking oil is a valuable commodity reused in a variety of markets. In the United Kingdom, the developing markets for reuse of this waste oil is bio-fuel, which is fuel used for heating and diesel. ...


  • Treatment of ship sludge oil using a plasma arc waste Destruction system (PAWDS)

    The Plasma Arc Waste Destruction system (PAWDS) uses a plasma torch to quickly gasify solid  waste on board ships. Developed under the support of the US Navy, this compact one deck system has been in commercial operation on board a cruise ship for more than three years. With the support of Carnival Cruise Lines and the National Research Council of Canada, the PAWDS was recently modified in ...

  • A novel approach to remediating contaminated groundwater by reusing industrial co-products

    This paper presents a novel approach to remediating contaminated groundwater by utilising industrial co-products. The materials discussed include paper clay and steel slag, and the primary water contamination considered is heavy metal contamination. Paper clay was determined to have the potential for adsorbing heavy metals, and in compacted form could achieve permeability values within the ...

  • Leaching of milled asphalt pavement amended with waste to energy ash

    The environmental suitability of using Waste-to-Energy (WTE) ash as a partial substitute for aggregate in hot-mix asphalt concrete was investigated using a series of leaching lysimeters. Eight samples of processed asphalt concrete manufactured with 25% by weight WTE ash as aggregate were leached using stainless steel lysimeters. A ninth lysimeter contained asphalt without WTE ash. Simulated ...
