Well, it took us a long time, but Alberta farmers are finally taking an abundant resource (cow plop) and spinning straw into gold. Brilliant!
Turning manure into power
March, 2005
The often-criticized methane gas produced by livestock operations is being harnessed in a new process that has potential to light homes in towns and cities across the country.
A pilot plant in north-central Alberta, which may become the first of many in North America, is expected to draw considerable attention as it begins processing solid feedlot manure to produce electricity. The Integrated Manure Utilization System (IMUS) will process manure from Highland Feeders' 36,000 head feedlot near Vegreville, Alta., to produce power and other value-added by-products. Initially, the plant will extract methane from raw manure to fuel electrical generators that will produce one megawatt (one million watts) of electricity and has capacity to scale up to produce about three megawatts, typically that's enough power to supply electricity to a town of more than 5,000 people.
The dry solid by-products of the process are useful as an environmentally friendly fertilizer, while the liquid component will be recycled as irrigation-quality water. The project is believed to be the first co-generation plant of its kind in North America that uses solid feedlot manure to produce energy. Another similar project at the Iron Creek Hutterite Colony in Viking, Alta., has been using liquid hog manure to generate power since 2002.
The concept is aimed at solving or reducing a number of the environmental challenges associated with handling large volumes of feedlot manure. At the same time, products resulting from the process will provide value-added revenue that covers the capital cost of the IMUS system, and provides a revenue stream for the operation.
Raw feedlot manure is a valuable nutrient source, but it presents a range of social and environmental challenges for feedlot operators. It produces odour, releases greenhouse gases when improperly handled, is expensive to haul, and presents challenges to the maintenance of ground and surface water quality.
The range of benefits from IMUS include:
* Reduced manure handling costs.
* Protection of water resources.
* Odour reduction.
* Recycling of waste water.
* Reduced energy costs.
* Value-added revenue from the sale of energy and bio-based fertilizer.
* A stronger reputation of the agricultural industry's environmentally sustainable resource management.

that is, indeed, brillant!
Talk about a great way to recycle natural waste products!

Actually to me, that sounds like a lot of bullshit.
Sounds like one of Ralph Klein's ideas...

Maybe Ralph will stop pouting about the Kyoto accord now, and start showing some leadership. Now, if they could only harness the hot air coming out of the Alberta Legislature building ;-)
