We've a really good example of that in Manitoba with IISD, the International Institute for Sustainable Development. They've done a cattail project, where they've used cattails to extract nutrients from the Netley-Libau Marsh. They've actually proven that this technology works. You harvest the nutrients and use the cattails as a source of bio-energy, and then the ash can be reused later on as fertilizer. Although we consider the nitrification risks to Lake Winnipeg to be a tremendous liability for our environment, this could be our next big asset for the future if we can harvest these nutrients and somehow market them as a fertilizer. Fertilizer is a big variable cost for producers. If these nutrients are all tied up in sediment in the lake, any work that can be done on technology to extract those nutrients would be very useful.
