  • Methane and carbon dioxide emission from two pig finishing barns

    Received for publication July 22, 2007. Agricultural activities are an important source of greenhouse gases. However, comprehensive, long-term, and high-quality measurement data of these gases are lacking. This article presents a field study of CH4 and CO2 emission from two 1100-head mechanically ventilated pig (Sus scrofa) finishing barns (B1 and B2) with shallow manure flushing systems and ...

  • Unlocking the potential of poultry manure

    The poultry industry is one of the largest and fastest-growing agro-based industries in the world. At the same time, the growth brings along a number of environmental problems. One of the major environmental problems is the accumulation of large amounts of wastes, e.g. manure. In order to mitigate these problems new economically sustainable technologies are needed. Manure has often been ...

  • Formation and emissions of ammonia and greenhouse gases from stored and composted solid animal manure

    Beside other branches of industry, agriculture is an important source of methane (CH4) and nitrous oxide (N2O) emissions and the most important source of ammonia (NH3). In spite of several investigations concerning ammonia and greenhouse gas emissions during storage and composting of liquid and solid animal manure, the real extent of these emissions is still unknown. This is mainly because of the ...

  • Is Energy Efficiency the correct path to a lower carbon economy?

    European researchers have identified a new “fuel” that by 2030 will be more important than oil. It’s called energy efficiency − the drive to get more bang from each buck spent on power. If the European Union member states adopt a 40% energy efficiency target, the sum of energy ...

  • Emissions from Crops - POST Note

    Agriculture contributes 9% of the UK’s greenhouse-gas (GHG) emissions burden and 10-12% globally. Although there is a long-term declining trend from UK agriculture, the sector may account for a larger share of overall emissions in the future as other sectors reduce emissions. This POSTnote focuses on reducing GHG emissions from growing and storing arable and horticultural crops. ...

  • Planting trees and managing soils to sequester carbon

    As of 2007, the shrinking forests in the tropical regions were releasing 2.2 billion tons of carbon per year. Meanwhile, expanding forests in the temperate regions were absorbing 0.7 billion tons of carbon annually. On balance, a net of some 1.5 billion tons of carbon were being released into the atmosphere each year, contributing to global warming. The tropical deforestation in Asia is driven ...

  • Empowering Alberta: Pioneering spirit gives boost to province`s alternative energy projects

    While biofuels are getting plenty of attention these days, biorefining - the process of converting biomass into biofuels and bioproducts that may also produce energy - is evolving. It's now at a point where organizations such as Alberta Life Sciences Institute, Alberta Agricultural Research Institute and the Alberta Forestry Research Institute are focused on positioning the provinces as a global ...

  • Worming the way to finished compost

    SCREENING AND GRINDING When materials from CR&R and other generators are unloaded, a preliminary screening separates out nonorganic contaminants.    Even though there are source separated programs in places like Temecula and Lake Elsinore, there is the occasional appearance of plastic and glass that needs to be sorted out. Next, Bodlak‚Äôs crews put materials through a Vermeer tub ...

  • Have humans tilted the climate books out of balance?

    In the great book-keeping of climate change, scientists have just discovered a big mistake. They have been wrong, they now think, to count on the mountains, the plains, the forests and the grasslands as an agency that slows climate change by absorbing carbon dioxide. It does absorb carbon dioxide. But the chilling news is that  ...

  • Clean, green and powered by cow patties

    Two dome-like structures rise out of the thick ice fog of a Prairie winter day. From a distance, a science-fiction city seems to be taking shape on the rolling grasslands of east-central Alberta. Then, as you draw near, another sensation takes hold – the oppressively pungent odour of cow manure. On this day, the enveloping fog is making the smell worse than usual, explains Bern ...

  • Evaluating composting for contingency bases

    Technology is being evaluated to demonstrate a potentially viable supplement to waste incineration at Department of Defense bases that support operations of deployed units. To help address the solid waste management challenges at Department of Defense contingency bases overseas, the National Defense Center for Energy and Environment (NDCEE) is demonstrating an in-vessel composting ...

  • Cow-pattie power

    On a massive cattle feedlot located outside the town of Vegreville, Alta., the pungent odour of cow manure is masked by the sweet smell of the province’s energy future. Turning cattle dung — “brown gold,” as some call it — into green power and other valuable byproducts is a made-in-Alberta energy solution that is not only sustainable and energy efficient, but also ...

  • Closed-Loop Companies

    At Big Rock Brewery, spent grain is used as cattle feed. Pictured here is brewmaster Paul Gautreau. Alberta may not always get an A-grade when it comes to the environment, but in some areas the province’s enterprises are on the leading edge. In industries from agriculture to forestry to beer, Alberta businesses are taking their own initiative to become closed-loop producers – that ...

  • Chicago Council lists three-decade changes in greenhouse gases and average temperature

    In 2011, we wrote a column, “Global warming is happening: How should farmers respond?” (http://agpolicy.org/weekcol/549.html). In that column we began by saying, “There was a time when one could legitimately argue that there was a lack of scientific agreement over the issue of the role of humans in global warming and even whether we were in a ...

  • Anaerobic Digestion at Dairy Farms

    The need to upgrade dairy waste management practices to overcome pollution problems is leading more farmers to seek solutions with anaerobic digestion technology. Two recent examples of this trend are underway at California sites. The Cal Poly Dairy is located adjacent to the California Polytechnic State University campus in San Luis Obispo. The dairy milks 180 cows with a total population of ...

  • Going green in 2012: 12 steps for the developing world

    Many of us are thinking about the changes we want to make this year. For some, these changes will be financial; for others, physical or spiritual. But for all of us, there are important resolutions we can make to “green” our lives. Although this is often a subject focused on by industrialized nations, people in developing countries can also take important steps to reduce their growing ...
