Composting & Carbon Farming

Why Compost? (start time: 7:01) Many of us may feel a little less guilty letting fruits and vegetables go bad, because we figure that this waste, thanks to curbside compost pickup, will be turned into nutritious food for crops, lawns or grasslands down the road. And landfills will spew less methane, a greenhouse gas far more potent than carbon dioxide. The story of food waste and reuse is a complicated one. Our two guests are working on getting composting right — and ultimately on how to make our food-production and consumption systems more sustainable, starting here on the Front Range.  Dan Matsch directs the compost department for Eco-Cycle, the nonprofit recycler that works with cities along the Front Range. He also directs Eco-Cycle’s Center for Hard-to-Recycle Materials (CHaRM). Mark Easter is an ecologist at Colorado State University’s Natural Resource Ecology Laboratory.  Matsch and Easter discuss with host Susan Moran the journey of a rotten zucchini, how composting is tied to the emerging practice of carbon farming, and how we all do our part.

Calendar advisory: Join KGNU and Eco-Cycle on Thursday, January 31, at the Longmont Museum (6:30 to 8:00 P.M) for a special community conversation on plastic waste–challenges and solutions. The event will include representatives from Eco-Cycle, the Inland Ocean Coalition, and local business and sustainability leaders. For more info, go to this website.

Nicotine Patches // Restoring the Desert

Do nicotine patches really help you stop smoking?  Shelley Schlender interviews a scientist who says they don’t.  Lois Biener and her colleagues at the University of Massachusetts and Harvard University  have done a study that  indicates that out in the real world, people who use nicotine replacement therapy in the hopes of an easier “quit” don’t fare any better than people who use will power and community support.  Some people who use nicotine replacements are actually MORE likely to relapse.  (Extended interview version here).

Great plumes of dust rising from the desert forms an iconic image of the West, but much of that dust is a result of humans altering the desert soil structure.  Several Boulder scientists are investigating a new technology that may allow us to restore the desert, and sequester large amounts of carbon at the same time.  Tom McKinnon interviews Jim Sears, president of  A2BE Carbon Capture and  Bharath Prithiviraj, a Postdoctoral Research Associate in Chemistry and Biochemistry at the University of Colorado.  They are developing a large scale deployable technology that would enable agricultural aircraft to re-inoculate and restore arid soils using indigenous strains of soil-crust-based cyanobacteria. For additional information on airborne soil crust reseeding, its research and its applications please contact jimsears@algaeatwork.com for an overview paper on the topic.
