  • Can we bury the carbon dioxide problem?

    Seriously — carbon capture and storage could be a game-changer. Mention “carbon capture and storage” — the process of trapping carbon dioxide produced in fossil-fuel burning or other industrial processes and burying it underground — in polite company, and you’re likely to be pounced on. It’s absurdly expensive. It can never be rolled ...

  • Intellisenc Building Air Quality Controllers control CO2, CO, VOC, O3, Humidity and temerpature.

    The quality of the air we breathe indoor (Indoor Air Quality, IAQ) is typically defined by the air chemical or gas composition and particulates. The sensors available today for sensing the gas composition of IAQ have many features and options. There is a wide application base for IAQ sensing with the most common being the regulation of HVAC ventilation systems for lower energy cost. Using an IAQ ...


  • Latin America well-positioned for CDM

    The coastal desert of Colombia’s La Guajira state is a world away from Kyoto, the temperate Japanese city where representatives of 159 countries in 1997 signed the Kyoto Protocol on reducing greenhouses gases. The Caribbean laps against rickety settlements. Herds of goats range across scorching sands. Months, whole years, pass without rain. But Kyoto is well known to the inhabitants of La ...

  • Japanese Organics Recycling Association Formed

    Another backyard composting adage states that compost should have the feel of a wrung-out sponge — damp but not dripping wet. Actually, a wrung-out sponge may be on the dry side for composting, but the analogy does provide a great image for understanding the reasons for balancing moisture. Like a compost pile (or windrow or material in a vessel), a sponge is a solid mass containing an enormous ...

  • These fires are huge, hidden and harmful. What can we do?

    Smoldering peat gives off massive quantities of carbon dioxide and other pollutants, but the search for solutions is on. As forest fires devastated Fort McMurray, Alberta, last month, a different sort of fire may have started beneath the ground. Peat, a carbon-rich soil created from partially decomposed, waterlogged vegetation accumulated over several millennia and the stuff ...

  • How some climate “wins” can lead to other uphill battles in the clean energy fight

    Proponents should consider all possible reactions in order to create a smoother path forward for clean energy. As the adage goes, following every action is a reaction. As elsewhere, this is true in politics, where every move is followed by a series of countermeasures. Lately, climate and energy have increasingly been at the political fore. It follows then, that climate policy ...

  • In-Vessel Composting of Residential Organics

    In 1994, the Regional Municipality of Peel began work on a system for residential organic residuals collection and composting. Although Peel had been promoting backyard composting, greater diversion rates were sought. The public was surveyed to determine what level of cooperation could be expected for source separation and setting out of food, soiled paper products, yard trimmings, etc. “We knew ...

  • EPA studies identify techniques for critical leak testing prior to soil-vapor sampling

    Researchers at EPA’s National Risk Management Research Laboratory (NRMRL) in Ada, OK, are developing quality assurance (QA) measures for soil-gas and sub-slab sampling methods that help differentiate contaminant vapors due to vapor intrusion from background sources. Recent research focused on measures to identify leakage of ambient air into conventional vapor probes, which can significantly ...

  • Start up of Indonesian Cinnamon Plant employs screen classifying cutter, rotary mixer

    Starting up a new process plant can be a tricky business for any company, but when it is the first plant the company has ever built and the location is halfway around the world from equipment suppliers, the project can be daunting. So it was with ForesTrade, Inc., when it set about building Indonesia's first state-of-the-art organic cinnamon-processing plant and an associated essential oils plant ...

  • Tiny materials in countless products raise big questions for environment and health

    Nanotechnology opens a universe of possibilities — but also creates a world of unknowns. In recent years, efforts to develop the Next Big Thing — whether in medicine, computer technology, pollution prevention or high-performance materials — have turned to some really, really small things: nanomaterials. Working at the ...

  • Warmest Decade on Record Brings Record Temperatures and Weather Extremes

    In recent years weather events have whiplashed between the extremes of heat and cold, flooding and drought. Carbon dioxide and other greenhouse gases—largely from the burning of coal, oil, and natural gas—have loaded up in the atmosphere, heating the planet and pushing humanity onto a climatic seesaw of weather irregularities. High-temperature records in many places are already being ...

  • The whey to renewable energy

    When Tom Wilson with the Pennsylvania State University Cooperative Extension set out to study the feasibility of a community-based anaerobic digester in Mercer County, he initially analyzed processing manure collected from area dairies and food wastes gathered from the local college, nearby prisons and industrial food processors. But the economics of transporting the materials just did not make ...

  • Sustainable wastewater separation treatment systems coupled with nutrient and water reducing greywater reuse technologies

    Nationally and internationally, pressure is increasing to introduce nutrient reducing, water conserving and recycling measures for sustainable residential and small community water/wastewater systems. Reports of inadequate water quality and quantity are being reported daily. Over the past thirty years the federal government and State of Alaska have invested over 4 billion dollars installing piped ...
