  • 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 ...

  • 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 ...

  • 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 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 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 ...

  • Engine manufacturer saves $200,000 per year

    The Problem: A “Big 3” engine manufacturer was dumping their 140,000 gallon central coolant system over shutdown every year. As oil contamination, metal fines, and aluminum soaps built up in the fluid, plant engineers noticed that surface finish decreased and tooling usage increased. As a remedy, the system was dumped, cleaned, and recharged with fresh coolant. With a ...

  • Tyre aggregate applications in geotechnical and geoenvironmental engineering

    A Tyre Aggregate (TA) is made from scrap/waste rubber tyres. Four types of tyre aggregates are classified, namely the coarse-grained, fine-grained, random and composite tyre aggregates. Applications of these tyre aggregates are varied, but they are often used as geomaterial fills and highway-pavement components. More recently, TA has found application in geoenvironmental engineering. This paper ...

  • 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 ...

  • Municipal waste management & handling

    Several MSW management practices, such as source reduction, recycling, and composting, prevent or divert materials from the wastestream. Source reduction involves altering the design, manufacture, or use of products and materials to reduce the amount and toxicity of what gets thrown away. Recycling diverts items, such as paper, glass, plastic, and metals, from the wastestream. These materials are ...

  • The growing E-waste problem

    If your current PC is too slow or running out of storage space, it’s probably more cost-effective to replace it than to upgrade it. But what happens to your computer once you replace it? The workplace mantra of “reduce, reuse, recycle” often ends with office paper and aluminum soda cans. As a result, myriad computers considered obsolete by today’s standards sit unused in back rooms or end up in ...
