  • Occupational exposures to lead-based paint in structural steel demolition and residential renovation work

    Occupational exposures to lead are characterised for a number of different lead-based paint abatement techniques in two work settings: residential renovation and structural steel demolition. Exposure levels reported during heavy structural steel demolition work involving acetylene torch cutting, welding, and abrasive blasting can be more than 100 times greater than the permissible exposure limit ...

  • Smelter gas cleaning one vessel from the quench to the drying tower

    Base metals such as zinc, lead and copper are all found in nature bound with sulphur as sulphite minerals: sphalerite (ZnS), galena (PbS), several copper minerals, silver (found as acanthite Ag2S), and, along with other precious metals. Processing of the metals invariably leads to sulphur dioxide (SO2) formation. Other metal processing, such as aluminum from bauxite ore [Al(OH)3] which contains ...

  • Removal of contaminants from industrial wastewater through various non-conventional technologies: a review

    It is difficult to separate industrial growth from environmental pollution but it can be minimised through cost-effective approaches of pollution abatement. To reach the full objectives of zero pollution, adoption of alternative technologies which suit the situation of low capital availability, minimum man-power and limited energy consumption are necessary. Adsorption through agricultural ...

  • 25 Years of Success – Outokumpu Stainless DC Plasma Smelting Facility

    Design is not just what is looks and feels like. Design is how it works. Between 1982 and 1987, British Steel (Outokumpu today) made extensive investigations into the treatment of steel dust. Their research was far and wide and covered off many various methods of recycling, including alternative to plasma technologies. But, in 1985, they engaged Tetronics International to carry out a ...

  • The Greening of Carbon Fibre

    Carbon fiber is a material that has, and will continue to revolutionize the products we use every day by making them stronger, lighter and more durable.  Experts estimate that the specialty material is twice as stiff as steel and five times stronger, per unit of weight.   It is made from organic polymers which consist of long strings of molecules held together by carbon atoms.  The ...

  • Asbestos contaminated soil case study

    An active gypsum manufacturing facility discovered they had a large area of gypsum waste containing asbestos mixed with soil at the back of their property. The waste had accumulated over the years before the dangers of asbestos were known and now required remediation due to communication wires buried in the waste. Excavators could not be used due to the presence of the communication wires that ...

  • Falling Through the Cracks

    An old environmental ghost has recently been reincarnated. Polychlorinated biphenyls (PCBs) provided plenty of scares in the 1970s, when studies found that the PCBs commonly used as insulators in electrical equipment (particularly transformers that leaked the substance into soil and water supplies), were not only carcinogenic, but also that PCB pollution tended to accumulate and become magnified ...

  • Guide to asbestos in the workplace

    Asbestos is a well-known hazard in many workplaces - whether the asbestos is part of the work itself, or whether it is simply in components of the building or site where work is being performed. Employers are bound by regulations of both the US Environmental Protection Agency (EPA) and the Occupational Safety and Health Administration (OSHA) that serve to protect employees from asbestos exposure ...


  • Asbestos in Buildings: Practical Guidelines for Building Owners

    Practical guidelines for building owners Overview Friable asbestos-containing materials are present in many public and commercial buildings, schools and factories built before the mid-70's. Regulations in Ontario and some other provinces require building owners and property managers to put in place asbestos control programs, once they are aware of the presence of friable asbestos-containing ...


  • ACS installation at Glowood 100,000ton/y pellet plant achieves 12mg/Nm3 - Case Study

    With increasingly tougher restrictions on industrial air emissions, pellet manufacturers are looking to "future-proof" particulate matter (PM) compliance, cost effectively. One Portuguese producer, Glowood Indústria S.A., has recently installed a brand new type of mechanical cyclone. The most recent results show a remarkable reduction of its PM emissions, from 700mg/Nm3 to under ...

  • Legal Lookout: EPA Proposes Lead-Based Paint Removal Requirements

  • Effective Temperature Control for Cement Kiln Off-Gases

    INTRODUCTIONEffective off-gas temperature control without unwanted side effects can be achieved in many cement plants with state-of-the-art evaporative spray technology. Gas temperatures have elevated in recent years from as low as 180°C to over 370°C. This is coincident with a higher proportion of 'dry' operation kilns. Evaporative cooling water sprays in conditioning towers, ducts or at the ...


  • Controlling Stack Emissions in the Wood Products Industry

    Electrostatic precipitation has been a reliable technology since the early 1900's. Originally developed to abate serious smoke nuisances, the manufacturers of zinc, copper, and lead quickly found electric gas cleaning a cost efficient way to recover valuable product carried out of the stacks from furnace operations. Today electrostatic precipitators are found mainly on large power plants, cement ...

  • Noise Measurement

    Definitions Threshold and criterion levels The threshold level is the A-weighted sound level at which a personal noise dosimeter begins to integrate noise into a measured exposure. For example, if the threshold level on a sound level meter is set at 80 decibels (dB), it will capture and integrate into the computation of dose all noise in the employee's hearing zone that equals or exceeds 80 dB. ...


  • Total solution: Gas and particulate analysis in Cement industry

    Cement plants are increasingly required to install continuous emission monitoring systems (CEMS). While these represent a significant financial outlay, a range of other factors also need to be considered when selecting a suitable CEMS. To the inexperienced, selecting a suitable CEM can mistakenly be considered as simply ensuring that the applicable national regulations (eg MACT in the USA, ...
