  • Minsur - Tin giant gets boost from TOMRA ore sorting technology - Case Study

    A plant for treating mined waste and low grade material at the world’s largest underground tin mine has repaid its capital cost of US$24 million in just four months, thanks in part to the role of a TOMRA X-ray transmission (XRT)-based ore sorting machine. The plant went into operation in 2016 and is projected to contribute 6,000 tonnes of refined tin to the ...

  • Passive evaporation of source-separated urine from dry toilets: UES optimization and dry product accumulation over time

    A urine evaporation system (UES) was optimized and evaluated in a laboratory by adding 5 L of urine at the same time each day for 65 days. The UES consisted of a wooden box that is open at the front only with tracks for 22 vertically stacked cafeteria-type trays and a fan and chimney at the back. Urine flowed from tray to tray via gravity exiting each tray via a weir along the long side of the ...

  • Dry regenerable sorbents for the separation and capture of CO2 from large point sources

    The combustion of fossil fuels generates large quantities of carbon dioxide (CO2), a greenhouse gas most likely to influence global warming and climate change. Large stationary sources that include coal-based electric generating stations are plausible targets for the removal of CO2. Chemical absorption of CO2 is viewed as one option that could be applicable ...

  • Sludge Drying Overview - Treatment Methods and Applications

    Sludge is a residual, semi-solid by-product left from industrial or refining processes. It is a separated solid suspended in a liquid, typically containing major quantities of interstitial water between its solid particles.  This material can be dried to cut its volume and reduce most of the moisture content of the biosolids present in the sludge. ...

  • Electrostatic Separation of Mixed Plastics Waste

    A major environmental problem is mixed plastics waste. Because of the incompatibilities of the properties of different polymers, mixed waste is either land filled or reused in low value applications such as plastic wood. The barrier to economic re-use of these materials is separation into pure components. Recycled pure plastics can be used in place of virgin material and thereby much of the ...


  • AVA - the fast way of API drying - Case Study

    AVA dryers for pharmaceutical substances meet and exceed International standards GMP and FDA, also for HP APIs. AVA dryers are customized units, made of high-quality steel (e.g. hastelloy). They can be equipped with fully automatic containment solutions or manual glove boxes to ensure maximum of industrial safety measures. Clamped flange joints and CIP/WIP nozzles make AVA dryers extremely easy ...

  • Rest or mixed waste sorting-digestion-separation for the recovery of recyclables and energy

    Source separate collection of biowaste has been implemented in many countries in Europe, especially in the German- speaking countries and the Benelux. By separating the biowaste fraction, a waste fraction called rest waste or grey waste is left over. This fraction is in most instances landfilled or incinerated. However, rest waste still contains a considerable amount of organics (up to 65%) which ...
