  • Safety Considerations at Anaerobic Digestion Plants

    Anaerobic digestion is a collection of processes which naturally breakdown organic matter to eventually produce biogas - a methane rich gas which is burned to produce both heat and electricity. The methane can also be used as vehicle fuel or injected into the gas grid. The industry is growing fast and is forecast to continue to do so with many farmers adding bio-gas plants alongside their ...

  • Waste Disposal

    Introduction The final step in the waste management process is waste disposal, the permanent isolation of waste. Some wastes can be managed and disposed safely with existing facilities and proven methods. Other Department of Energy (DOE) wastes require more complex disposal facilities. DOE has conducted extensive research into alternative waste disposal methods and has concluded that deep ...

  • Waste not, want not

    Consultant Andy Ive considers solutions which not only comply but also enhance the environmental profile of today’s industrial companies. Until recently the prevailing perception in many industries, particularly those operating in emerging market areas has been that waste is an unwelcome inconvenience. The primary infrastructure of most companies was fundamentally not designed to deal with waste ...

  • Drivers of solid waste minimisation in Finnish metal engineering SMEs: the role of Environmental Management Systems

    The paper reports on a survey in Finnish small- and medium-sized metal engineering enterprises (SMEs) with certified Environmental Management System (EMS). Waste awareness has increased after certifying EMS and the treatment of solid waste has improved; source separation of solid waste facilitated the recovery of recyclables and their diversion from landfill. EMS has raised knowledge levels, in ...

  • The Chemical Engineer - The Forgotten Earth

    Demand for minerals is on the rise, as is their price. No wonder then that industry is looking to extract minerals from what once would have considered waste. In this article, Dr Tim Johnson of Tetronics explains how plasma technology plays its ...

  • World-Wide-Waste

    Also showing was a picture of Pripiat, the abandoned city near Chernobyl, that features in the recent Russian (recycling) detective story: “Wolves Eat Dogs” by Martin Cruz Smith, where “hot” cars and trucks are being cannibalized for cheap after-market spares (engine blocks) for East Europe. This year the USA Waste Expo setting in Las Vegas was an astounding location city for a waste expo, given ...

  • Wood waste recycling

    A customer has built a very successful business grinding wood waste banned from the local landfill and selling the wood fiber. They operate a system that was fully engineered and manufactured by WSM, including conveyors, magnetics, WSM 48-10 Disc Screen, WSM 4064BH Horizontal Hogging system, and support structures. A heavy duty vibrating conveyor feeds the wood waste into the hog. Ground material ...

  • Waste water recovery

    Wastewater Treatment Recovery and Recycling Supports the Environment. Industrial Waste Water Treatment has encompassed industrial waste water recovery and recycling for a long time now, and it's getting better and better.No longer do wastewater producing industries nonchalantly discharge wastewater into runoff systems that eventually merge with the water cycle whether in lakes, streams or in 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 ...

  • Maximising biogas in anaerobic digestion by using engine waste heat for thermal hydrolysis pre-treatment of sludge

    EXECUTIVE SUMMARY Dublin's Ringsend WWTP was designed to serve a population of approximately 1.2 million pe with a sludge production of 37,000 dry tonnes per year after upgrading to full secondary treatment. Several technical solutions were put forward as part of a Design, Build, Finance and Operate (DBFO) competition, with the chosen solution being a proposal by Black and Veatch for a ...

  • Management of Hazardous Wastes

    ' Management of hazardous waste is a growing concern in many countries. The long-term impacts and costs of improper disposal can be very high and the emphasis must be on prevention. A comprehensive management system should include (i) policies, institutions and effective regulations and (ii) adequate and acceptable disposal facilities (either public or private). This note outlines the key ...

  • Engine manufacturer saves $45,000

    The Problem: An engine manufacturer was faced with costly lost production in their 10,000gallon central honing oil system. The central system had been contaminated with 1500 gallons of water. The oil supplier’s lead-time for replacing the oil was just over 72 hours, and draining, cleaning, and drying the system would add to the downtime. SRS had already been conducting a successful coolant ...

  • Engineering Innovation into Driveline Design

  • Application of coupled thermostatted columns in civil engineering and for leaching heavy metals of wastes from foundry sands and mining industry

    For many years, the mining industry at Pachuca Hidalgo, Mexico, has produced silver and gold through a cyanide process. Solid wastes (tailings) of this process have been deposited close to centres of population. Many of the metals in these wastes are dispersed via wind and rain, and can be toxic to flora and fauna. Foundry sands are wastes, produced by the automotive industry, the metallurgy ...
