  • Zero landfill is not zero waste

    THE Zero Waste movement is more than just a vision. It is a movement that is actually changing the world. To prove it, I recommend visiting GreenBiz.com and in the search box type “zero waste.” You will be amazed, as I was, at the tsunami of business activities over the last couple of years related to the idea of totally eliminating waste from our manufacturing, distribution and ...

  • Zero waste, Saudi Arabia

    The Saudi Iron & Steel Company (Hadeed) has a strong commitment to the environment. Hadeed's 3R waste management strategy – reuse, recycle, recover – includes recovering valuable metals, and re-using baghouse dust (from industrial air filters) in concrete cement. Harsco has a long track record of recovering valuable metals from steelmaking co-products, and in the same process ...

  • Welcome to Net-Zero

    For most people (and for most homes) the likelihood of going through a whole year spending next to nothing on energy is a goal that seems far out of reach. In fact, it is only relatively recently that insulation technologies, coupled with cutting-edge renewable energy tools, have made the concept of a net-zero energy use home anything more than a pipe dream. However, thanks to a program at the ...

  • Zero Waste System in Paradise

    Most visitors to Fiji come for rest and relaxation on the white sand beaches or for diving and snorkeling among the unspoiled coral reefs. Few visitors realize that this tropical island in the South Pacific, north of New Zealand, is on the cutting edge of industrial ecology with a fully functional, zero waste program located near the Fijian capital of Suva. As part of an EPA funded review of ...

  • Field and Laboratory Evaluation of the Treatment of DNAPL Source Zones Using Emulsified Zero-Valent Iron

    Emulsified zero-valent iron (EZVI) is a surfactant-stabilized, biodegradable emulsion that forms droplets consisting of a liquid-oil membrane surrounding zero-valent iron (ZVI) particles in water. This article summarizes the results obtained during the first field-scale deployment of EZVI at NASA’s Launch Complex 34 (LC34) located on Cape Canaveral Air Force Station, Florida, in August 2002 and ...


  • Denmark’s Near-Zero-Waste Wonder

    Has this Danish community found the formula for environmentally friendly industry? When we look closely at systems in nature — coral reefs or rainforests, for instance — we see something we don’t often see in human systems: mutually beneficial relationships and energy flows among the various elements, such as air, water, rocks, soil, and plant and animal life. If we ...

  • Ground Zero Air Quality Has A Long Way To Go! A Summary of Air Quality Testing in Surrounding Buildings

    There are still a wide range of concerns about air quality in the vicinity of Ground Zero. Many commercial and residential spaces have yet to be re-occupied. In only a few cases has any sort of inspection or testing been done to determine if they are safe to occupy. The greatest concerns are asbestos and the very irritating concrete dust that spread throughout lower Manhattan during the collapse ...

  • Zero emissions day: What it is and why we need it

    Today is September the 21st – a day that didn’t hold any particular significance until a simple observation occurred in the 1980’s. Ken Wallace, father of a newborn daughter, realized, after witnessing the local neighborhood pizzeria truck, parked, running and driverless, combined with the surrounding traffic that “Stopping all this for a bit would be most excellent for ...

  • 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 ...


  • Hydrogen Storage - Solution for an Intermittent Energy Source

    Storing solar energy through hydrogen versus traditional storage solutions Today, energy is either transmitted directly to the consumer through the grid or stored as backup power for future use via batteries, pumping water, etc. When it comes to solar and wind energy, it becomes extraordinarily difficult to take full advantage of the renewable sources using traditional methods of power ...

  • Evaluation of airborne heavy metal pollution from European sources

    An improved MSC-East model for the evaluation of the atmospheric concentration and deposition of heavy metals in Europe and adjoining regions is described. At present, modelling of lead, zinc, arsenic, cadmium and mercury concentrations is carried out within the EMEP grid. At the same time, MSC East performs model calculations within the whole northern hemisphere to the north of 20°N. Each ...

  • Sulphur dioxide dispersion from a main point source in Portugal: comparison between models

    A simulation of sulphur dioxide dispersion from a power plant was carried out using CRSTER, MPTER and POLUX models. The first two models are from the Environmental Protection Agency and the third one is from the Department of Environment and Planning of the University of Aveiro. Both episodic and long-term simulations were made, including model performance comparison and analysis of model ...

  • Canadian biofuel manufacturer requires air pollution control

    With the expected rise in oil prices in the next few years, the increasing instability of the world oil supply, and the increasing demands from the EPA for cleaner fuels and production processes, Food and Plant based Ethanol production is on the rise. Along with this rise in production comes an increased requirement for Air Pollution Control Solutions in the Bio-Fuel’s market. Catalytic ...

  • New air quality rules challenge oil & natural gas industry

    EPA Administrator signed a suite of proposed new air regulations affecting both the Production/Processing and Transmission/Storage sectors of the oil and natural gas industry. The proposed rules mandate the use of emission controls as well as work practices through two different air regulatory programs – New Source Performance Standards (NSPS) and National Emissions Standards for Hazardous ...

  • NOx in Non-Utility Industries - Part I NOx in Non-Utility Industries - Part I - Air emission origins, best control solutions and monitoring methodology for nitrogen oxides

     Problems with reducing nitrogen oxides (NOx) are widespread in the general process industries. These industries, together with medium size utility and power generators contribute about 15 percent of global NOx emissions. The emission sources addressed include various heaters employed in chemical and petrochemical plants, nitric and sulfuric acid plants, glass furnaces, iron and steel mills, ...


  • Estimation of the exchange of sulphur pollution over the Balkan region in 1995?2000

    The Bulgarian dispersion model 'Eulerian Model for Air Pollution' (EMAP) is used to estimate the sulphur pollution over the Balkan region for the period 1995?2000. A subdomain of the European Monitoring and Evaluation Programme (EMEP) grid is chosen containing 12 countries. The computational grid in this domain has a space step of 25 km, twice as fine as the EMEP grid. The former operational DWD ...

  • Thermal Patters Due to Moisture Accumulation within Exterior Walls

    In cold climates, air leakage is accompanied by moisture transport. When migrating through dew point temperatures, a considerable amount of moisture accumulation may occur depending on variables such as the duration of sub-zero exterior temperatures, building pressurization, wind effects and the level of interior relative humidity. Moisture accumulation may result in premature deterioration of ...

  • Heat Pumps – FAQs

    1. What is a Heat Pump? To put it simply; ground source heat pumps and geothermal heat pumps produce high grade heat from low grade heat which is found in the earth and our atmosphere.2. How does a Heat Pump Work?Heat pumps work in exactly the same way as air conditioners or refrigerators, but in reverse! Heat pumps capture latent energy which is stored in sources such as air, water and earth. ...
