Although I can envisage a lower-energy society, getting there seems like a white water-ride!<BR/><BR/>So, both these articles and many others you have sent that reinforce biomass and recycling, in a local context are I think part of the solution.<BR/><BR/>Phosphorus is the key element.<BR/><BR/>Sustainably yours - we hope!<BR/><BR/>Chris.Professor Chris Rhodeshttps://www.blogger.com/profile/12060542089215379056noreply@blogger.comtag:blogger.com,1999:blog-19508699.post-310395399880515632008-09-14T20:01:00.000+01:002008-09-14T20:01:00.000+01:00Peak Phosphorus Sustainable Phosphorus Futures Unl...Peak Phosphorus <BR/>Sustainable Phosphorus Futures <BR/><BR/>Unlike oil, which is lost once used, phosphates can be recovered and recycled. However, phosphorus <BR/>cannot be replaced once resources begin to be depleted: there is no substitute. At present, 80% of <BR/>phosphate mined is lost in fertiliser production, field application, food processing, and does not reach the <BR/>food we consume. Worldwide, mankind emits 3 million tonnes of phosphorus annually in faeces and <BR/>urine, with even more in animal manures. Human emissions represent more than 10% of phosphate rock production. Recovery and recycling of <BR/>phosphorus offer an important opportunity to reduce dependency on mined phosphates and make food production more sustainable. <BR/>Quoted from SCOPE Newsletter#71.<BR/><BR/>CEEP, a Sector Group of CEFIC is the joint research association of the European detergent and industrial polyphosphates industry, sponsors research into phosphates and the environment and into phosphate recycling, and publishes the SCOPE Newsletter.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19508699.post-25264326157671088522008-09-13T04:37:00.000+01:002008-09-13T04:37:00.000+01:00Hi Chris, More grounds for optimism?http://www.pos...Hi Chris, <BR/><BR/>More grounds for optimism?<BR/><BR/>http://www.pos.ca/news/article.php?article_id=52<BR/><BR/>"...Recently, algae biomass created via photosynthetic microbial<BR/>bioproduction techniques has gained attention as a feedstock for<BR/>biofuels production because its conversion to fuel requires less energy and does not compete with food crops..."<BR/><BR/>POS Pilot Plant is a confidential contract research, toll processing, and analytical services organization located in Saskatoon, Canada.<BR/>Sustain_ably yours,<BR/>GeorgeAnonymousnoreply@blogger.com
