Apr 12: Sustainability Salon on the End of Waste

Global population is on track to peak at over 10 billion later this century.  Food distribution could and should be a lot more equitable than it is, but no matter how you look at it, that's a lot of people to feed.  We need to consider land use -- can we afford to convert more biodiverse ecosystems to monoculture cropland?  Or should we make better use of land already in agriculture, by sustainably nourishing the soil?  And we need to account for the main limiting nutrients for agricultural production: nitrogen and phosphorus.

Most conventional fertilizer includes nitrogen derived from fossil methane, and phosphorus from rock phosphate -- often dug from open pit mines.  The ongoing wars at the eastern end of the Mediterranean, and the blockade of the Strait of Hormuz, are compounding the supply problems -- and worsening global food shortages are predicted for the coming year.  

At the same time, these elements are found abundantly in human "waste".

For the 171st Sustainability Salon, a "soft opening" to our annual Food feature, we'll explore the End of Waste:  utilizing organic material (previously considered "waste") to generate soil, fertilizer, and energy.  

Mary Dobbs, 

Back on this side of the pond, John Stolz is a biologist, a former Congressional candidate, and the Director of the Center for Environmental Research and Education at Duquesne University.  He is a strong advocate for using biogas, including from human waste, in place of fossil methane;  it can travel in the same pipes and be burned for energy in the same appliances.  

Ecotone Renewables is a Pittsburgh-based B-Corp (a Benefits Corporation, which expands institutional priorities beyond mere profit to include the health of people and the planet).  They have pioneered modular biodigesters in use at

Please check out the list below for other important events happening in our region (and online).

This salon will take place on Zoom.  The program will start around 3 p.m.  As always, join us for whatever time works for you!  If you're not already on my salon email list, please email me (maren dot cooke at gmail dot com) with "salon" in the Subject line to be added -- and let me know how you heard about salons!  If you RSVP via Eventbrite, you'll receive the Zoom registration link right away. Along about Saturday night/Sunday morning, I'll send it out again, with other information, to all who have RSVP'd.  If you're new to Zoom, you may find my Zoom Reference Guide helpful.  

Note that starting last fall, I shifted salons an hour EARLIER, at least for this fall and winter, and maybe beyond --the program will start around 3 p.m. Eastern.  Why?  During our sabbatical in Ireland last year, I connected with many new friends and enviro-colleagues, some of whom have or will speak at salons, and others who are interested in attending. And there's generally a five-hour time difference (sometimes 4 or 6 hours because our savings-time shifts are on different dates). Also, logistics have evolved with in-person salons since 2021, so earlier should also work better here at our Pittsburgh site. 

Other events and whatnot (times are U.S. Eastern):

•  Mar 28:  The third national No Kings protests -- there will be at least four events in and around Pittsburgh (N hills 10 a.m., Pittsburgh at noon, S Hills 4 p.m., Shadyside 5 p.m.).  More info on the nationwide events here, and here are the deets on events in and near Pittsburgh.  And if you're local, you can connect up with the newsletters mentioned several items down in this list to learn more about opportunities for action and advocacy.

•  To find ways to get active in our region, I encourage local folks to sign up for the Indivisible Grassroots Pittsburgh email list, which will bring you lots more listings, more frequently -- email Debra.  There's also Fighting Back, by Alison, with up-to-date emails on lots and lots of protest actions and other events.  Nobody can be everywhere, but all of us should be somewhere!  

•  And for valuable perspective on the day's news, consider following Heather Cox Richardson, Robert Reich, Rebecca Solnit, and/or Robert Hubbell.  In our own region, folks like Patricia DeMarco, John Russell, and Susan Kaye Quinn are worth your time.  Their work can be found variously in places like Substack, YouTube, BlueSky, Mastodon, Instagram, Facebook, and their own books, blogs, newsletters, and/or podcasts.  This list is hardly comprehensive, but these links can connect you with some of our time's leading thinkers, writers, and speakers.  

•  Concerned Health Professionals of NY recently released the 9th Edition of the Compendium of Scientific, Medical, and Media Findings Demonstrating Risks and Harms of Fracking and Associated Gas & Oil Infrastructure.  Check it out!  

•  We know that only a tiny fraction of plastic has ever been recycled.  And yet, NPR has been airing sponsorship messages for the American Recycling Council, which is continuing to perpetrate the "recycling" hoax.  Does that make your blood boil?  The national group Beyond Plastics has a petition/sign-on letter to get them to stop -- please sign, for yourself or for an organization you represent!

•  It's been well over two years now!  You can support striking Post-Gazette workers here (and consider signing up for the alternative online publication, the Pittsburgh Union Progress -- and maybe even cancel your P-G subscription until they start treating workers fairly!).  This strike has garnered national attention;  one recent picket even made it into Teen Vogue.

•  PRC continues to hold online workshops about composting, rainwater harvesting, and waste reduction.  They have several Hard-to-Recycle events each year; upcoming events are listed here.  For household chemicals, here's the link.

•  The Rachel Carson EcoVillage is still looking for a few more members.  Curious?  You can sign up for an introduction session or sign up as an “inquirer” to have more information sent to you.

•  Have you seen the film Single-Use Planet (hopefully soon to appear on PBS), or The Story of Plastic, or the PBS docs Plastic Wars, Fenceline, and We're All Plastic People Now?  (and/or join us for Plastic Paradise at a winter film salon seven years ago?)  ...What if you could bring up imagery of the toxic impacts of plastic production, and commentary by the people and communities living with them, over the world?  You can do all that with the interactive Toxic Tours tool.  Check it out!  

•  Mask update:  Breathe99 masks (featured in a 2020 salon on Pandemics and Air (video), and one of TIME's 100 Best Inventions of 2020) are now being distributed by Our Children Our Earth, a local purveyor of alternatives to disposables (as well as classy wooden toys).  Contact Dianne via OCOE's Facebook page, or call (412) 772-1638 to coordinate a curbside pickup (or you can still order online).

For the uninitiated, a Sustainability Salon is an educational forum;  it's a mini-conference;  it's a venue for discussion and debate about important environmental issues (and often health, and justice, and politics);  it's a house party with an environmental theme.  Each month we have featured speakers on various aspects of a particular topic, interspersed with stimulating conversation, lively debate, and (when in person) delectable potluck food and drink and music-making through the evening.   Beginning in early 2012, salons were originally a potluck mini-conference;  the event has been either on Zoom or outdoor/hybrid since March 2020.  This event series was featured in the Pittsburgh Media Partnership's Pittsburgh Story project on Civic Catalysts -- here's a piece by The Allegheny Front.
