  • Safety in handling wood pellets

    Canada is primarily a bulk producer and exporter of pellets with large mills that make, on average, 56,000 tonnes per year, said Staffan Melin. When shipped in large volumes, pellets are classified as hazardous material, although wood pellets in consumer bags are benign. For example, carbon monoxide (CO) gas emissions released by pellets killed a person in the cargo hold of a ship in 2002. A ...

  • Sample Handling Strategies for Accurate Lead-In-Soil Measurements in the Field and Laboratory

    ABSTRACT The inhomogenous lead-in-soil matrix can present serious obstacles to accurate sample collection and handling. In typical lead-in-soil measurement, particle size related errors in sampling and sample handling often exceed all other sources of error. The magnitude of error can vary widely depending on the particulate nature of the lead contaminant and the effectiveness of control ...

  • Modelling of sediment nutrient fluxes for a pulsed organic load

    A sediment model has been developed to simulate the Sediment Oxygen Demand (SOD) and sediment nutrient fluxes after a sudden input of Particulate Organic Matter (POM). Compared with previous sediment models, the main advances are the use of a continuous function to represent the kinetics of POM diagenesis and inclusion of the biomass content in POM diagenesis. Laboratory experiments were also ...

  • Quantitative analysis of Powdered solids case study

    Introduction Infrared quantitative analyses are an everyday requirement in the analytical laboratory. While liquid solutions are commonly analyzed, mixtures of powdered components also exist and often require quantitative analysis without dissolution into a solvent. This paper outlines the development of quantitative analysis methods for two powdered mixtures. The traditional ...

  • Preliminary studies of lignocellulosics and waste fuels for fixed bed gasification

    This study was carried out to understand the decomposition behaviour of a range of biofuel and waste feedstock during gasification in a downdraft gasifier. A laboratory scale large sample thermogravimetric analyser (LSTA) is used which allows the data on burn-out characteristics of different fuel particles to be measured under agitated conditions. The conditions chosen simulate the combustion ...

  • Aminoglycoside Antibiotics in Feed Apramycin, Gentamicin, Neomycin

    Aminoglycoside antibiotics are among those commonly used in animal feeds to manage intestinal microorganisms. The beneficial effects include improved growth and generally healthier animal populations. Use of antibiotics creates a demand for analytical procedures to verify concentrations in pre-mixes and feeds and in some instances for residue analysis in animal products. This note describes a ...

  • Carbon Dating in Oxford

    Several members of our team visited the Archaeology Department (RLAHA) at the University of Oxford recently, to discover how some of our products were being used at the University. Interestingly, they were informed that our presses were part of the carbon dating process for bones. The Department receive bones that have been founnd by archeologists in excavations or sometimes by ...

  • Daniel Casey: Exploring a ‘little star’ on Earth

    Written by Leda Zimmerman.You can read the original new in MIT NewsIn 2010, after a decade of meticulous preparation, Daniel Casey and an MIT team finally ran their experiment. The world’s largest laser struck a millimeter-sized target, and in less than a second, it was ...

  • US Regulation of Wood-burning and Indoor Air Pollution

    Recently, the US EPA released their final proposal to update the new source performance standards (NSPS) for new woodstoves and heaters, and to add NSPS for the first time for pellet stoves, furnaces, hydronic heaters, and masonry heaters.   The measures, if approved, would take effect in 2015.  The report states, "Emissions from wood stoves occur near ground level in residential ...

  • LIMS is the Anchor for Next-Gen Mining - News from MINExpo 2012

    Thermo Fisher Scientific, Inc. exhibited its Next-Gen Mining portfolio during MINExpo 2012 in Las Vegas, September 24-26. The company’s highly integrated range of instruments, equipment and consumables, anchored by its industry-leading laboratory information management systems (LIMS), is the only offering that addresses all segments of the mining process, from early stage exploration ...

  • Time is of the essence in plastics

    Introduction Determining the moisture content in plastics is an important step in the extrusion and molding process of many industrial resins.  Excessive moisture content can lead to microscopic steam pockets that can blister or weaken the integrity of the molded product.  Plastic pellets in a saturated or ‘wet’ state can also mislead buyers of bulk plastic since ...

  • Operator Strategies : Sorting Out the Plastic

    BETTER BUGS Ideas and products in the Better Bugs category attempt to affect the biological components and biochemistry of processes by altering the mix of microorganisms or enzymes present. After all, biology is the foundation of many, if not most, organics recycling systems. Pyrophiles: The first example of Better Bugs involves pyrophilic organisms, bugs that can take the heat. This example is ...

  • Making India`s waste streams sustainable

    MIT researchers are developing a decision-support tool to help cities in India sustainably manage the societal and environmental impacts of their waste. The massive Deonar dumping ground in Mumbai has become the most visible emblem of an increasingly serious nationwide problem for India: what to do with its trash. Deonar’s towers of garbage are ...

  • Moving difficult-to-handle bulk materials with flexible screw conveyors

    Flexible screw conveyor systems can be engineered to transport bulk materials that tend to pack, cake, smear, break apart or fluidize, and can prevent the separation of blended products. Flexible screw conveyors (Fig. 1) are suitable for most bulk materials, from sub-micron powders to large pellets, both free-flowing and non-free flowing. They are capable of conveying bulk materials at any angle ...
