  • Case study - Finally - a fan for the 21st century

    Travis Luther, owner of Forcefield, designs and builds Advanced Greenhouse Climate Solutions in southern Oregon, USA. He bought MagFans for his greenhouses and he is impressed with the powerful, efficient and quiet fan. - Being in a hot dry climate, we rely on evaporative cooling to keep the temperature from climbing to detrimental levels in the summer. This requires massive air flow to ...

  • Fluorinated greenhouse gases 2013

    Aggregated data reported by companies on the production, import and export of fluorinated greenhouse gases in the European Union. Background and policy The greenhouse gases (GHGs) covered by the UNFCCC Kyoto Protocol include three groups of fluorinated GHGs (the so-called 'F-gases'): hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) ...

  • Fluorinated greenhouse gases 2012

    Data reported by companies on the production, import and export of fluorinated greenhouse gases in the European Union Background Greenhouse gases covered by the UNFCCC Kyoto Protocol include amongst others, three groups of fluorinated greenhouse gases (F-gases): hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF6). These F-gases have ...

  • Fluorinated greenhouse gases 2011

    Greenhouse gases covered by the UNFCCC Kyoto Protocol include amongst others, three groups of fluorinated greenhouse gases (the so-called 'F-gases'): hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF6). These F-gases typically have very long lifetimes in the atmosphere and high global warming potentials (GWPs). The European Union Regulation (EC) No 842/2006 on ...

  • Methane flux in cropland and adjacent riparian buffers with different vegetation covers

    Received for publication September 12, 2008. While water quality functions of conservation buffers established adjacent to cropped fields have been widely documented, the relative contribution of these re-established perennial plant systems to greenhouse gases has not been completely documented. In the case of methane (CH4), these systems have the potential to serve as sinks of CH4 or may provide ...

  • Native cover crops suppress exotic annuals and release native perennials in a greenhouse competition experiment

    In a greenhouse experiment, we examined the effectiveness of four native cover crops for controlling four exotic, invasive species and increasing success of four western North American grassland species. Planting the annual cover crops, annual ragweed (Ambrosia artemisiifolia) and common sunflower (Helianthus annuus), reduced the biomass of the exotic species cheatgrass (Bromus tectorum), ...

  • Bottom line on regional cap-and-trade programs

    Three regional greenhouse gas cap-and-trade programs are either in the planning stages or operational in North America. This brief discusses each of the programs. What is happening on the regional level and why is this significant? Twenty-three U.S. states and four Canadian provinces are actively participating in the design and implementation of three regional cap-and-trade programs to ...

  • An indoor screening method for improvement of freezing tolerance in alfalfa

    Freezing tolerance is a determinant factor of persistence of alfalfa (Medicago sativa L.) grown in northern climates. Selection for winter hardiness in field nurseries is difficult because of the unpredictability of the occurrence of test winters allowing the identification of hardy genotypes. A method of selection entirely performed indoor in growth chambers and walk-in freezers has been applied ...

  • Composting and local food merge st urban garden

    Growing Power (GP), a nonprofit urban garden and training center in Milwaukee, Wisconsin, provides affordable produce to neighborhoods without access to fresh food, and processes a variety of organic wastes through composting and anaerobic digestion. Located on a two-acre lot on Milwaukee's north side, the six greenhouses and several hoop houses include raised beds for herbs and greens, ...

  • New routes for roads: using recycled greenhouse films to modify bitumens

    Four recycled greenhouse films made of low density polyethylene and EVA copolymer, are mixed with 6070 penetration grade bitumen. The goal is to improve the viscoelastic properties of bitumen used as a binder in road pavement, contributing to an environment improvement by reducing plastic waste. It is observed that a reasonable stability and a satisfactory upgrading face to rutting defect at high ...
