  • 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 ...

  • Commercial Experiences :Time for (compost) Tea in the Northwest

     Understanding Compost Tea COMPOST TEA describes many different preparations made using compost as a starting material and producing a liquid extract or in some cases a “liquid version” of the original compost. There are many home-designed pieces of equipment and some commercially available equipment made to produce compost tea. New ideas abound on how to fabricate the better tea-maker and ...

  • Greenhouse gas, animal performance, and bacterial population structure responses to dietary monensin fed to dairy cows

    Received for publication January 27, 2009. The present study investigated the effects of a feed additive and rumen microbial modifier, monensin sodium (monensin), on selected variables in lactating dairy cows. Monensin fed cows (MON, 600 mg d–1) were compared with untreated control cows (CON, 0 mg d–1) with respect to the effects of monensin on the production of three greenhouse gases (GHG), ...

  • Using ICT to Drive your sustainability strategy

    Australian corporations and government bodies face the imperative to create a platform in their own organisations to tackle the complex issue of climate change through sustainability strategies. Sustainability means taking responsible action and providing solutions that improve operational resilience, commercial sustainability and environmental sustainability with the resultant environmental, ...

  • How US businesses can access federal stimulus money

    I thought that “federal stimulus” would be high on Google’s hit list. But alas, when I checked its analysis of hot trends yesterday, I discovered that “Rockin’ Robin” is number one.Thanks to American Idol this 1950s song dominates the search engine. Bringing more music to the ears of business owners, however, is the $20 billion made available for energy efficiency through the American Recovery ...

  • The effect of amendment of vegetable waste compost used as substrate in soilless culture on yield and quality of melon crops

    One of the main environmental impacts of forced systems in horticulture — such as plastic covered and soilless culture — is the generation of organic plant residues and substrate waste. Many people are keen on research and development of ecologically friendly substrates. Thus, leaching experiments have been carried out with distilled water to determine whether compost — from horticultural ...

  • Study of agglomeration in 3.5 MW AFBC using rice husk particles

    The combustion of rice husk in fluidised bed combustors seems to be an attractive possibility for power generation in the future, keeping in view the waste disposal problems and the reduction of greenhouse gases. In commercial installations, the occurrence of agglomeration is still one of the main reasons for unscheduled outrages. In this paper, a review of agglomeration mechanism and its ...

  • Compost maturity effects on nitrogen and carbon mineralization and plant growth

    Improved predictive relationships between compost maturity and nitrogen (N) availability are needed. A total of 13 compost samples were collected from a single windrow over a 91 d period. Compost stability and maturity were assessed using both standard chemical analyses (total C and N, mineral N, total volatile solids) and other methods (CO2 evolution, commercial maturity kits, and neutral ...

  • District Energy Comes of Age

    Three milestones in 2006 signal new energy for an old idea. When Thomas Edison wrote, “Genius is one percent inspiration, ninety-nine percent persperation,” he could have been describing how hard-working district energy executives feel about their accomplishments in 2006. How else to account for the sense of momentum in a previously-obscure sector of the energy industry that marked its commercial ...

  • Las Vegas DirtWorkz, Inc.: Using the City’s wood waste to farm the desert

    Ray Becerra knows a thing or two about recycling, reusing and repurposing waste materials. You might even say it’s in his blood. Becerra has spent his entire life around landfills and farming operations, and he wears his passion for recycling waste materials on his sleeve. His enthusiasm for dust, dirt and debris, says Becerra, comes from his father, an avid recycler who was involved in the ...

  • Research highlights cattle emissions reduction opportunity

    Researchers in Denmark have measured the quantities of greenhouse gases in the breath of dairy cows and demonstrated a heritable variability between individual animals. “This means that we have an opportunity to select for breeding those individuals which will produce offspring that generate less methane,” says Dr Jan Lassen who led the research project on individual methane ...
