  • Reduced Emissions for Landfill Gas Installations

    The use of landfill gas as a source of renewable energy is increasing. For environmental and safety reasons, the owners of the waste storage sites have to strictly monitor and control the construction, operations, and emissions generated. Sulzer offers solutions to control these emissions within the limits given by the government. Landfill gas is similar to natural gas, but it is created by ...

  • Case study - Catalytic oxidizer catalyst replacement

    Overview A New Jersey pharmaceutical company purchased a thermal incinerator to treat the heptane and hexane exhaust from their capsule wash system. The thermal incinerator"s "tubular" design was modified with a catalyst bed in order to reduce the system"s operational costs. Unfortunately, when operating in the catalytic mode, the oxidizer failed to provide the required ...

  • Optimization of Anaerobic Digestion & Bio-Organic Catalyst Compositions (BOCs)

    Abstract: Anaerobic digestion offers excellent opportunities to convert organic waste streams into environmentally safe bio-solids and generation of renewable energy through the bio-methane produced by the microbiological populations processing the wastes. Bio-organic catalyst compositions (BOCs) offer improvements in enhancing anaerobic biological activity and raising bio-methane ...

  • Characterization and ecological risk assessment of nanoparticulate CeO2 as a diesel fuel catalyst

    Nanoparticulate cerium dioxide (nano‐CeO2), when combusted as an additive to diesel fuel, was transformed from 6 nm to 14 nm sizes into particles near 43 nm, with no obvious change in the unit cell dimensions or crystalline form. Cerium sulfate, if formed during combustion, was below detection limits. Ceria nanoparticles were agglomerated within the soot matrix, with a mean aerodynamic ...

  • Platinum group metal recovery from spent catalysts case study

    The Challenge Catalyst wastes, including automotive catalytic converters and industrial catalysts, contain Precious Metals and specifically Platinum Group Metals (PGMs), which are valuable as a result of their low natural abundance, unique properties as well as the complex and costly processes that are required for their extraction and refining from primary sources. Furuya Metal Co. Ltd., ...

  • Recovery of Precious Metal Catalysts - A New Process Using Supercritical Water Oxidation

    Up to now, the recovery of precious metals used as catalysts in chemical processes has involved the use of incineration. Now, however, a British-Swedish joint venture has developed a process which uses supercritical water oxidation instead, which provides many economic and environmental advantages. Precious metals are used extensively in catalysts in a wide range of industrial chemical processes. ...

  • Optimisation of Binder and Catalyst Addition: Steel Castings Pty Ltd

     Steel Castings Pty Ltd installed a computerised ‘Autocat’ system to control the addition of catalyst and binder for the production of sand moulds. The finer control of addition rates has significantly reduced the number of reject moulds and achieved annual savings of $21,780 from reduced raw sand and chemical costs. Background Steel Castings Pty Ltd operates a foundry ...


  • Recovery of Ruthenium and Other PGMs from Spent Petrochemical Catalysts

    The recovery of platinum group metals from spent petrochemical catalysts has economic benefits by the protection of the supply chain of these valuable and rare metals, thereby helping to create a sustainable value chain in the petrochemical industry for catalysts. Introduction The platinum group metals (PGMs) are used extensively in catalysts for the petrochemical industry owing to ...

  • Working towards sustainability through environmental stewardship and collaboration

    In May 2006, Administrator Stephen Johnson asked the National Advisory Council for Environmental Policy and Technology (NACEPT) to review the U.S. Environmental Protection Agency’s (EPA) recent response to two priorities—environmental stewardship and cooperative conservation. In this concluding report to the Administrator, the Council advances key recommendations, findings, and steps the ...

  • A Link between Plant Profitability and Environmental Stewardship?

    Utilizing the latest separation technologies, Mobile Process Technology delivers complete solutions to any site in the world   The pervasive opinion that environmental stewardship is nothing but a drain on company resources is far more than a misconception. It’s bad business. Yet, with regulations tightening and public ...


  • Environmental tax reform in Europe: opportunities for eco-innovation

    Environmental taxation, innovation and the green economy 'Environmental taxation can spur innovation.' This simple, compelling message was a central finding of a recent OECD study of taxation, innovation and the environment (OECD, 2010). It is an insight of profound importance. Environmental policy instruments are frequently characterised as obstacles to economic activity ...

  • RAISING THE BIOSOLIDS BAR: DEVELOPING AN ENVIRONMENTAL MANAGEMENT SYSTEM
