The new washing and water management plant (which includes a Gennaretti centrifuge system) will provide NRL with the ability to divert recycled aggregates from landfill and supply high quality clean washed materials to the local construction...
New ways for Metal Recycling
REWAVE XRF 3-way-sorting in innovative “Free-Fall”-design Recycling of metal and aluminium knows no limits because it can be remelted as scrap indefinitely. Metals, however have to be separated from non-metallic impurities, and different metals have to be sorted in pure fractions to be used as secondary raw materials substituting primary resources. Especially when it comes to aluminium a lot of energy can be saved when remelting scrap aluminium. By using secondary raw materials in the production of...
Case study - Wastewater lagoon cover stops odor complaints
Problem: United Liquid Waste Recycling (ULWR) successfully recycles food and beverage waste into valuable by-products such as fertilizer. Odors from their anaerobic treatment process needed to be stopped to enable ULWR in Watertown Wisconsin to expand. Their two lagoon anaerobic digesters needed an affordable system to control odors. ULWR injects their valuable fertilizer into farm fields twice per year, so the system needed to function whether the ponds were full or empty.Solution: The owners of ULWR selected...
Fresh look at organics bans and waste recycling laws
Approximately 40 percent of food produced in the U.S. is wasted annually. At a time when millions of Americans are food insecure and thousands of farmers struggle to stay afloat, the negative consequences of wasting food extend far beyond the environmental impacts and loss of resources that could have been otherwise allocated. There are great opportunities for food waste reduction at the federal level, but much can be done by states and localities, whose involvement in finding solutions to food waste and food...
Is it time to recycle more nickel?
Now you might think me a little sad, but I have to confess that as a metallurgist, I always find it interesting just how closely the history of mankind is linked to advances in metal working. The first evidence of metal working in Europe dates from around 5500 BC with the extraction of copper, lead and precious metals and this was followed by the working of bronze from around 4000 BC, both of which mark key points in the emergence of modern civilisation more generally. The growing use of new techniques to...
