  • Measuring carbon in steel – absolute reliability matters

    The incorrect analysis of the carbon content in steel can lead to a multitude of issues down the line, making accurate and reliable carbon analysis critical. Our OES expert Willy Sanders looks at why… Carbon steel has been in use for nearly 2,000 years, but rose to prominence during the late industrial revolution when steel makers really began to exploit the properties that a little carbon ...

  • BioCycle World

    Economic Impact Of Recycling In Texas The Texas Commission on Environmental Quality (TCEQ) released its recent study on the economic impact of recycling activities in the state. Approximately 9.2 million tons of MSW designated materials were recycled in Texas in 2015. Typical recyclables (paper, plastics, metal, and glass), organics (yard trimmings, brush, green waste, and food and ...

  • Vibration testing of a carbon composite fuselage

    This paper describes the details of an experimental investigation focusing on the vibration characteristics of a composite fuselage structure of an ultralight unmanned aerial vehicle (UAV). The UAV has a total empty weight of 70.3 kg and 6.3 m in length. The fuselage structure consists of the fuselage body with an integrated vertical stabiliser. All structural components are fabricated from ...

  • Static and Cyclic Direct Shear Tests on Carbonate Sands

    This paper examines the static and cyclic behavior of different types of carbonate sediments and one type of silica sand under direct shear test conditions. For both static and cyclic loading, the effects of interface surface roughness, overburden pressure, void ratio, size and shape of grains, and saturation are studied. It is found that the static shear resistance is influenced by most of these ...

  • Development and testing of a European Union –wide farm‐level carbon calculator

    Direct greenhouse gas (GHG) emissions from agriculture accounted for around 10% of total European Union (EU) emissions in 2010. To reduce farming‐related GHG emissions, appropriate policy measures and supporting tools for promoting low‐carbon farming practices may be efficacious. This paper presents the methodology and testing results of a new EU‐wide farm‐level carbon footprint calculator. ...

  • Testing monolithic activated carbon adsorbers for in-line removal of organic micropollutants

    Anthropogenic organic micropollutants (OMP) occur along the whole urban water cycle including drinking water. Various OMP can be efficiently adsorbed onto activated carbon. In the present study a commercial monolithic adsorber (MA), originally developed for gas treatment, was examined for the removal of OMP from drinking water. As a promising advantage, the adsorber can be introduced into ...

  • Explaining the construction of global carbon markets: REDD+ as a test case?

    Market–based instruments increasingly shape international environmental governance. Against this background, this paper puts forward a conceptual framework on the development of regulated global carbon markets. Regarding the adoption of carbon trading as an instance of wider shifts in governance allows us to benefit from the rich literature on (international) institutional change. At the same ...

  • Carbon Monoxide (CO) Versus Carbon Dioxide (CO2)

    Carbon monoxide (CO) and carbon dioxide (CO2) are often mistaken for one another. Both gases are odourless and colorless and target the cardiovascular system. Both gases can enter the body through inhalation, skin and / or eye. Similar symptoms that both gases have in common are headaches, dizziness, seizures, and hallucination. Most people have a hard time determining the difference and do not ...

  • The Many Uses of Activated Carbon

    Activated carbon is processed to have small, low-volume pores that increase the surface area available for adsorption. It has applications in the medical, environmental and energy realms, among others. Since 1962, ASTM Committee D28 on Activated Carbon has developed standards that play a pre-eminent role in how activated carbon is used. A D28 ...

  • 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 ...

  • Carbon capture and clusters

    Carbon capture and storage (CCS ) announcements in 2013 were quiet – yet the award of funding to the White Rose project in early December was an encouraging sign that UK CCS momentum remains undeterred, explains Sam Botterill, CCS Technical Manager, Energy Institute. Christmas did not only come early for the White Rose project, more commonly referred to as Drax Power’s CCS Project, ...

  • A comparative study of three different assimilable organic carbon (AOC) methods: results of a round-robin test

    Easily assimilable organic carbon (AOC) is frequently used for the assessment of the biological stability of drinking water, which is an important consideration in the control of bacterial growth in distribution networks. The first AOC bioassay was developed in 1982 and is based on growth of two bacterial strains (Pseudomonas fluorescens P17 and Spirillum spp. NOX) in ...

  • Rapid small-scale column testing of granular activated carbon for organic micro-pollutant removal in treated domestic wastewater

    This study investigates the applicability of the rapid small-scale column test (RSSCT) concept for testing of granular activated carbon (GAC) for organic micro-pollutants (OMPs) removal from wastewater treatment plant (WWTP) effluent. The chosen experimental setup was checked using pure water, WWTP effluent, different GAC products, and variable hydrodynamic conditions with different flow ...

  • An assessment of biodegradability of quaternary carbon containing fragrance compounds: Comparison of experimental OECD screening test results and in silico prediction data

    An assessment of biodegradability was carried out for fragrance substances containing quaternary carbons by using data obtained from OECD 301F screening tests for ready biodegradation and from Biowin and Catalogic prediction models. Despite an expected challenging profile, a relatively high percentage of common‐use fragrance substances showed significant biodegradation under the stringent ...

  • The use of step and pulse tests to design activated carbon adsorption columns for recovery of copper ions from aqueous industrial effluents

    Dynamic experiments were carried out on the adsorption of copper ions in a laboratory packed bed of activated carbon. Both pulse and step change inputs were used. Measurements were reproducible and replicate measurements furnished nearly identical parameters for a conventional heterogeneous model of the activated carbon bed, assuming a Langmuir adsorption isotherm. Bed depth had little effect on ...

  • Activated Carbons and Manufactured Gas Plants

    The purpose of this paper is to discuss the pros and cons related to each of these factors when using one of three accepted options in conjunction with the "hog and haul" method of remediating a site. The options are the use of (1) minimal controls, (2) extensive onsite monitoring and (3) a fabric structure with limited air testing. As we are all aware, the government continues to react to ...
