  • Analysis of the impacts of an environmental traffic management system on vehicle emissions and air quality

    Environmental traffic management systems (ETMS) are implemented to improve air quality in urban streets. They allow for a situation-related control of light signal systems to optimise road capacities and enhance traffic flow in street sections. Therefore, they are equipped with mitigation strategies and continuously provided with traffic and air quality data. In this context, it is ...

  • Fertilizer Analysis Using Inductively Coupled Plasma Atomic Emission Spectrometry

    Wastewater disposal sludge, composed of a wide variety of substances, is effectively recycled as fertilizer. However, such recycling requires prior quality confirmation testing of the main constituents as well as the harmful constituents to ensure the safety of the resultant sludge fertilizer. In the case of fertilizer classified as "ordinary fertilizer," the Japan's Fertilizer Control Law ...

  • Interpreting the IPCC emissions scenarios

    This paper discusses how two sets of emissions scenarios, generated using the Atmospheric Stabilization Framework, were used by the United Nations Intergovernmental Panel on Climate Change (IPCC). In particular, it discusses how the scenarios were specified, what roles models played in developing the scenarios, and how the scenarios were interpreted by participants in the IPCC process. It draws ...

  • Performance of the low-emission flare

    Job report / Elbisgraben (Bale / Switzerland) The summer of 1992 had finally arrived. The 5MW low emission furnace in the district heating station Liestal was ignited, supplied with landfill gas from Elbisgraben landfill. Since then the plant has been running continuously and the comprehensive measurements taken, verify that all targets aimed at have been achieved: plant ...

  • The characteristic differences in exhaust emissions, and fuel consumption analysis of unleaded gasolines produced by different oil companies in the Turkish market

    In Turkey, the differences in the properties of gasolines that are taken from different petrol stations are intensively discussed. By taking this as a starting point, the main target of this project is to examine these differences and how they affect exhaust emissions. The properties of nine gasoline samples taken from nine different petrol stations that belong to three different oil companies ...

  • Applying Kuznets theory to the analysis of relation between the economic development and greenhouse gas emission

    Proceeding from the empirical data analysis carried out for Ukraine and 37 other European countries, the author has traced a quadratic relation between the greenhouse gases emission level (at the example of CO2) and the economic development. The analysis focused on researching the possibility and reasonability of applying Kuznets theory to solving the modern environmental and economic issues of ...

  • An econometric time-series analysis of global CO2 concentrations and emissions

    This paper extends previous work on the econometric modelling of CO2 concentrations and emissions. The importance of such work rests in the fact that models of the Cohen-Labys variety represent the only alternative to scientific or physical models of CO2 accumulations whose parameters are inferred rather than estimated. The stimulation for this study derives from the recent ...

  • A cure for Environmental Emissions case study

    Disposing of nearly 1 million pounds of medical waste a month is no easy task. The wet electrostatic precipitator, installed at Rochester, MN-based Mayo Clinic, seems to be just what the doctor ordered. While the medical waste incinerator at Mayo Clinic in Rochester, MN, consistently met state and federal emission requirements, facility leadership recognized that installing a wet electrostatic ...

  • In-situ continuous emissions monitoring & regulatory compliance

    As environmental scrutiny has risen and regulation has tightened in recent years, the importance of having accurate information on the environmental performance of your power plant has increased. After all, if you want to manage something, you need to be able to measure it. The analogy is obvious; you wouldn't start a diet without first investing in a set of scales. So it is with Continuous ...

  • Proposed boiler MACT sets aggressive emission limits

    On June 4, 2010, U.S. EPA proposed National Emission Standards for Hazardous Air Pollutants (NESHAP) for industrial, commercial, and institutional boilers and process heaters at both major and area sources of hazardous air pollutants (HAP) emissions.  EPA proposed separate rules for units at major sources of HAP emissions (greater than 10 tons per year [tpy] of any single HAP and/or greater ...

  • Biofiltration of Ethanol Emissions from Bakery Operations

    The management of volatile organic compounds in bakery exhaust gases was identified as a high priority problem by the American Bakers Association in conjunction with their member companies. Biotrickling filter technology was evaluated among other approaches and was selected for a pilot study to control ethanol emissions from a bakery oven exhaust gas stream. Biofilters and biotrickling filters ...

  • Can Composting BMPS Reduce Air Emissions?

    Imagine a scenario where all yard trimmings collected for recycling have to be received, processed and composted under the cover of a building. It would be tough for most yard trimmings composting facilities to survive the expense. Yet this situation could have occurred in Southern California. At one point, the South Coast ...

  • Wastewater Treatment Plant Monitors Greenhouse Gas Emissions

    Globally, little attention is paid to gaseous emissions from wastewater treatment processes. This contrasts greatly with the regulatory monitoring that is applied to the quality of water emissions from such facilities. However, in Helsinki, Finland, a large municipal wastewater treatment facility continuously monitors its emissions of greenhouse gases (GHGs) to help in the city’s efforts to ...

  • Sources of PCDDs/PCDFs In Cement Kiln Emissions

    Abstract This paper presents data on the source of PCDDs/PCDFs in cement plant stack emissions, demonstrating that these emissions are not necessarily all created by the process. The data potentially demonstrates that some of the PCDDs/PCDFs in the emissions are pre-existing dioxins and furans that are vaporized out of the kiln raw feed. This calls into question the assumption that PCDD/PCDF ...


  • Content Analysis of Toxic Elements in Soil by Simultaneous ICP

    Contaminated soil not only leads to contamination of untreated drinking water through permeation into river water and rainwater, it adversely affects health when the soil itself is directly ingested as a child puts the ground into a stoma into a play etc. Therefore, assessment of soil toxicity using a defined method is required. I In Japan, the Soil ...

  • European Project on Portable Emissions Measurement Systems: `EU-PEMS` Project

    The European Commission through DG ENTR in co-operation with DG JRC launched in January 2004 a co-operative research programme to study the feasibility of portable emission measurement systems (PEMS) with a view to their application in Europe for in-use conformity (IUC) checking of heavy-duty vehicles. A six month planning phase between January and June 2004 concluded with the closure of the Call ...


  • FTIR gas analysis improves container safety

    Introduction Entry to freight containers represents a significant hazard to staff responsible for inspection, stuffing or destuffing because of the large number of airborne chemicals that can be present. Research in Germany and the Netherlands found hazardous levels of gases and vapours in around 20% of all containers and this level of contamination is now accepted as commonplace. It ...
