  • Product stewardship – recycling’s little helper

    Like many veteran recycling professionals, I have faced serious challenges in making the wish of recycling all materials come true.  Although paper, cardboard, cans and bottles have ready markets and collection infrastructure; computers, mattresses and other items did not.  They were the problem items that went into dumpsters because costs and lack of mechanism gave them little chance ...

  • Thoroughly modern installers keep on industry trend

    The ErP Directive, through its various iterations since 2009, not only places high demands on the efficiency levels of a wide range of heating products, and especially hot water storage in our homes, but also on installers to communicate the benefits of greater energy efficiency to their customers. If the target to reduce energy use by 20% by 2020 is remotely realistic, not only has product ...

  • Tire Shredding: The Best Alternative

    From cars and trucks to planes, tractors, and forklifts, tires are used for a wide variety of vehicles. And those tires don’t last forever. Regardless of how many miles a tire travels, it should not be used longer than ten years past its manufacture date, as the rubber will grow brittle and can crack. This isn’t usually a problem, though, since most tires are replaced within three or ...

  • Designing With Geosynthetic Clay Liners

    In construction, preventing the penetration of liquids and gases is essential to maintaining the integrity of a structure. Often, containment is just as important, especially when dealing with chemical contaminants or other waste. When looking to stop the spread of contaminated liquids and gases, there are few tools as effective as geosynthetic clay liners (GCL). Read on to learn how to design ...

  • Comparing nonreinforced and internally reinforced GCL

    Water is one of the most destructive forces on the planet, eroding everything from continents to human-made wonders. Water is also a vector by which contaminants spread from landfills and other waste reservoirs. Therefore, creating effective water seals has been a top concern in construction. For many years, factory-fabricated clay products have been the barrier of choice against water and other ...
