Toronto: Florida to the Kees with Greater Portland Inc.

Oct. 17, 2015

Richard Florida

Richard Florida, Professor; Co-founder CityLab.com; Sr. editor The Atlantic speaking to our Greater Portland, Inc. group.

Our discussion of “The Next Urban Crisis”  at University of Toronto, Rotman School of Management was another highlight of my Greater Portland Inc. trip to Toronto Sept. 27-30, 2015. There we spoke with professor, author and CityLab co-founder Richard Florida as well as  Real Estate Developer, & Architect in City blogger Brandon Donnelly.  During this discussion Spacing Magazine editor Matthew Blackett  also shared some of the interesting insights I reported on in my Part 1 blog.

Richard Florida expressed his frustration with the Mayor Rob Ford era which declared that the war on the car was over and that the problem was those young, pointy-headed university folks. “In Toronto, everyone still thinks they have the right to drive,” he lamented.  “If there’s an urban crisis, it’s the suburbs,” he said.

Florida reminded us that: “Building urbanism is a lot more expensive than building sprawl” and “The new frontier is the old frontier in the center of the city.” He left us with three points to deal with the next urban crisis: 1)  Build more housing,and make it more affordable; .2)  Build more transit;  3)  Provide a livable minimum wage–reduce the huge bifurcation we see now.

Brandon Donnelly discussed with us some of the crisis in keeping housing affordable during Toronto’s fast-paced growth. There’s a pressure on prices re: low rise, but high-rise has stayed stable, he said.  He described an Avenues and Mid-rise Building study. “ We see it as a market to build more units for families who are priced out of single family homes,” he said.

He distinguished Towers 1.0 and Towers 2.0.  Towers 1.0, many built in the suburbs, did not take as middle class housing and became largely the affordable housing of today. Towers 2.0 is basically all ownership vs. all tenants in 1.0, he said.  He finds it an encouraging sign that anchor office tenants and retailers are moving into the city as well.

On our way out, we had an unexpected opportunity to hear Robert Reich, who was doing a guest lecture at the Rotman School around his book, Saving Capitalism : For the Many, Not the Few. 

I was especially impressed by how many of our group stopped to listen to his talk.  “My aim is to shatter the myths that keep us from taking the action we must take, and to provide a roadmap of what we must do – to rebuild our economic system and restore our democracy.” Reich was saying.

There is  a “huge misunderstanding” that underlies  a false political dichotomy between the so-called “free market” and government intervention. “There is no choice to be made between the free market and government. Government determines the rules of the market. The real question is what those rules are going to be and who is influencing those rules and whether the market is going to be working for the vast majority as a result, or whether it’s going to be rigged in favour of a small minority.” Reich’s book was for sale at a table outside the open-sided auditorium where he was speaking.

At Rotman we had the opportunity to hear some of the most forward-thinking leaders of the day who are dealing with questions around the environment, housing, urbanism, equity, millenials, the creative class, public involvement and the economy.

It was a great segue to our reception and  “Sharing Best Practices between Portland and Toronto” session at Ryerson University Architecture School.  All of the students I met at the reception were from the Ryerson School of Urban and Regional Planning rather than Architecture.  Those students were looking for answers to rising housing costs, displacement, equity, brownfields, resiliency planning in an era of climate change, etc.  I stayed after the session to talk with them. Several promised to look at my blogs on mycoremediation and suggested that one of their professors might be especially interested. So far, no one has followed up but I’m still hoping to hear from them.

Chief planner Jennifer Keesmaat, is a longtime Toronto resident, a member of the Congress for the New Urbanism (like myself), and a pedestrian advocate.  She had been a principal in the Toronto planning consultancy Dialog prior to taking the job as Toronto’s top planner.   She is also an inveterate user of Twitter @jen_keesmaat–discreetly putting out these tweets while she was on a panel with Portland Chief Planner, Joe Zehnder:

Portland is seeking to create *greenways* throughout neighbourhoods to address stormwater issues. Think “greened” street medians.  Portland has met Kyoto carbon emission reductions, even while growing. “Your midrise is hi-rise for us.” Portland Chief Planner explains that 4 story bldings are causing consternation in his city. Wow. If only.

“I talk about Portland all of the time,” she told us.  We’re growing but our air quality is getting better – as a result of our green roof policy mitigating the heat island effect.  I cringed a bit to think that while Toronto passed the world’s first mandatory green roof program in 2010, Portland discontinued its Ecoroof Incentive in 2012.

In response to moderator Ann Marie’s question about green infrastructure and resiliency in the face of climate change, Keesmaat lamented that she has only three  people working on green streets, a superstar team, but only three.

She did add that Toronto is a city of ravines and that there is an ongoing Ravine Strategy currently being developed.  She will be holding her final Chief Planner Roundtable of 2015 (Dec. 15) on the topic of Toronto’s ravine network.  I did not get the chance to ask her about the re-naturalization of the Don River, but I plan to do that at the next opportunity–maybe via Twitter!

Mycoremediation: Testing Results In The Field

 

Jordan Weiss

August 6, 2015

When Jordan Weiss set out to use mushrooms to help clean up the soils and filter the water at the former landfill/brownfield site purchased by the Dharma Rain Zen Center (DRZC), he did so based upon the mycoremediation research of others such as Paul Stamets and his team at Fungi Perfecti.  He didn’t set up the effort as a research project.  He didn’t have funders to answer to as he volunteered his time and even many of the materials. He taught workshops that brought in the  volunteer labor from the Zen Center, the Oregon Mycological  Society and neighbors and friends.

Now, to take the project to the next level as a mycoremediation model for the Portland area, Jordan and others involved with the project, like myself, would like funding.  Funders always want  data–not just university lab data or even other people’s field data, but data from the project they are asked to fund.  I’m working with Jordan to figure out what baseline data is out there re: water quality and soils and what more data we need to collect to prove that mushrooms are removing toxins on this site and can do so throughout the Portland area.

Clean Soil to Garden Boxes

The Phase I Environmental Site Assessment for the DRZC site is of little help with regard to pollutants in water or stormwater. Essentially, its conclusion was: No analytical testing of shallow groundwater has been reported to ODEQ.  In the Phase II ESA, eight soil samples were tested in the area where the food garden is now.  High levels of PAHs were found in this soil, causing DRZC to build boxes and import clean soil for vegetable gardening.  The area where the raingarden is does not seem to have been tested.

Garden w/Berms

There are large berms (barely visible in the photo) at the north end of the garden where mycobags were placed on July 1, 2015–photo by PlanGreen

The best place to do future myco-remediation installations may be in the food garden area at the edges of the boxes since that soil had already been tested prior to any mycoremediation efforts, . After the mushrooms get established, DRZC and its partners could continue to test  the underlying soils for levels of PAHs.  The hypothesis is that the mushrooms and their mycelia will reduce or eliminate the PAHs.

PAHs (such as acenaphthylene’s, anthracene, benzo(g,h,i)perylene, fluorine, phenanthrene and pyrene) are listed by the EPA as possible carcinogens and maximum allowable standards are set for them.

BES Water Quality Chart

BES Water Quality Chart from Appendix A of 2008 Stormwater Management Facility Monitoring Report

We will want to do stormwater testing too.  The Portland Bureau of Environmental Services (BES) Stormwater Management Facility Monitoring Reports for both 2008 and 2010 tell us what water quality data BES monitors for in its stormwater facilities. From the chart in the Appendix of the 2008 report, we see that they monitor for oil,  grease, E. coli, metals, total phosphorous and orthophosphate phosphorous, ammonia-nitrogen and nitrate nitrogen in water.

Here’s what they test in the sediments:

BES Sediment Testing Chart

HCID/TPH is a screen to determine the presence and type of petroleum products in the soil

That HCID/TPH is a way to screen for PAHs and other petroleum products in the soil.  We do know that BES also does separate soil sampling. Some of the latest soil sampling data¹ shows that E-coli and heavy oil levels were higher than the background soil sample sites located nearby–but outside of the stormwater facilities. Metal and PAH levels found in stormwater facilities were generally similar to those found in background sample soils.  While these results show that soils in green street stormwater facilities (bioswales, raingardens) are likely taking up E-coli and heavy oil from runoff that would otherwise go down a storm drain, we hope to show that with the use of mushrooms, soil results could be cleaner than the background samples in all categories tested: E-coli, heavy oil, metals and PAHs.

Since toxins in surface water was not found t be a problem, the largest source of future pollutants may be from runoff from the parking area in the background of this photo–by PlanGreen

 

Since the only water sampling that revealed toxins at DRZC was the seep in the northeast corner of the site², our approach for monitoring the raingarden could start with the first rains of Fall 2015.  We would largely be monitoring for pollutants from the parking area west of the raingarden. Parking lots are well-known for contaminating stormwater with PAHs when it rains.

The Portland area is fortunate to have a second mycoremediation project underway in our region. In July 2015, I set up a meeting with Clean Water Services  Jared Kinnear and Pacific University toxicology professor Deke Gunderson to learn from their project to test mushrooms for cleaning street sweepings.  They hope to get the street sweepings–what appears to be the compost I buy in bags at Ace Hardware– to the point that it is judged safe for farmers’ fields.  They set up their project in conjunction with Fungi Perfecti which provided both the protocols and the mycelium inoculated wood chips for the research.

The project has evolved from what was originally conceived.  Because of time and labor constraints and the preliminary results, the project was modified from the original one that would have tested five species of fungi to just testing Stropharia rugoso annulata (King stropharia) and Pleurotus ostreatus (Oyster mushroom).  Then it was narrowed down again when the researchers found that the oyster mycelium stayed on the wood chips rather than spreading throughout the mixture of wood chips and street sweepings.

So they are now testing the ability of King stropharia mycelium to eliminate polycyclic aromatic hydrocarbons (PAHs) or at least reduce them to a level that they are safe to spread on farm fields.  The levels of PAHs are tested on a chromatograph at Pacific University. Since once the inoculated wood chips were added to the street sweepings, the levels of PAHs were so low that they were difficult to fully measure, the team decided to spike the experimental samples with PAHs in order to measure the effectiveness of the mushrooms.

The EPA has recognized 7 PAHs as priority chemicals due to their persistence in the environment.³ The most common way to be exposed is by breathing contaminated air but exposure can also come from  eating contaminated food. While we were there we met one of Dr. Gunderson’s students ,Hailey Jongeward, who has since shared with me her PowerPoint report on the project.

“Of the 7 priority chemicals we found traces of all 7 in the starting material, increasing the importance of this project” she wrote.  Those chemicals are: acenaphthylene’s, anthracene, benzo(g,h,i)perylene, fluorine, phenanthrene and pyrene.

Hailey also shared the photos of the subject material to the right.  Boxes get different ratios of wood chips to spores so that may account for the difference in the two boxes.  Both show that the mycelium is spreading, but the lower one more than the upper one.  Hailey also told me she is working in partnership with fellow Pacific University students Jake Prevou and Natalie Kimura.

I believe that the monitoring of the Dharma Rain Zen Center project needs to take on some similar elements as the Clean Water Services project and monitor soils for reduction of PAHs.  It would also be useful to test the water flowing into and back out of the raingarden, but that may prove more difficult because it was not designed for doing such testing.  Our best bet may be one identified in the Phase II ESA: “a location south of the seep had water discharge from piping, which was traced to a stormwater surface drainage feature.”

It is exciting to be part of the initiation of a technology–or rather a protocol for utilizing an ecosystem service from the seen and unseen mysteries of the natural world.  As we enter an era of climate change, such services will become more and more critical for adapting to changes, mitigating the impacts and healing our past wounds to the earth.  I want my business, PlanGreen, to be at the forefront of utilizing the services that nature provides for free.

Mycoremediation with “Spongy Parking Lots”

Aug 2, 2015

Portland’s Old Town China Town neighborhood has an abundance of surface parking lots.  In fact, it has far too many to be a vibrant neighborhood much less an expression of the eco-city that Portland purports to be.  I’ve joined with five other professional women to try to change that.  If we can’t see these central city lots immediately redeveloped to higher and better uses that house people and businesses, we at least want to see them become better parking lots–SPONGY PARKING LOTS.

Spongy Parking Lots Video image

Image borrowed from PDX Downtowner You Tube site.

My friend, Ruth Ann Barrett coined that term and even made a video about Spongy Parking Lots to share with her neighbors in Old Town/Chinatown.  She has friends who visit from California and she’s embarrassed to show them how much we waste water here in Portland.  When it rains, the water from those parking lots heats up and captures whatever pollutants vehicles leave behind on its way to the nearest storm sewer.  The surface parking lots are paved in asphalt and are major contributors to the urban heat island effect that raises the temperature as much as 10° over areas with open land and vegetation.  In turn, the extra heat increases the energy needed to cool interior spaces, and puts an extra strain on the grid by exacerbating peak energy loads and hence carbon footprint/climate change. It also contributes to smog formation adding even more public health impacts resulting from excessive outdoor temperature.

We’ll return to all that in a moment, but I first want you to remember walking on a trail in the woods where your feet just seemed to bounce on the earth beneath them.  That’s because that soil was kept porous and, yes, spongy, by the mycelium forming a thick mat that was turning wood to soil under your feet.  Those mycelium have fruiting bodies that we call mushrooms–which may or may not be visible during your walk.

Mycelium on log

The white stuff in this photo is mycelium. It will spread throughout the log and ultimately decompose it–creating spongy soil. Photo by PlanGreen.

That mycelium looks a bit like a very dense spider web criss-crossing to create quite a network.   It gets its nutrition by decomposing the cellulose in the log.  The ability of mycelium of mushrooms in the category of “white rot fungi”  to decompose cellulose is related to their ability to decompose numerous other substances as well: bacterial toxins such as e-coli and fecal coliform as well as polycyclic aromatic hydrocarbons(PAHs).  Research also shows their ability to transform  bunker fuel oil, explosives, polychlorinated biphenyls (PCBs), and organochlorine pesticides–substances we hope we won’t find in OTCT parking lots.

Ecotrust Parking Lot

Built in 2001, the parking lot at Ecotrust is an outstanding model of a “Spongy Parking Lot”. It probably even has a few mushrooms by now. Photo by PlanGreen

We do have models for Spongy Parking Lots nearby.  My favorite is at the Jean Vollum Natural Capital Center (aka Ecotrust) in the adjacent Pearl District neighborhood.  Often on a summer day, the cars are kicked out of this pleasant parking lot for an array of fairs, festivals and farmers’ markets.  If you enlarge this photo, you will see that the lot is paved with light colored porous pavers and that those trees are planted in bioswales that also hold an array of mostly native plants.  You will see that  the parking spaces drain into those bioswales. which are about 2.5 feet deep.  Not only do the soils and plants in  the bioswales infiltrate the water from the parking lot within 24 hours, they also cool the water and filter the pollutants that come from our vehicles and pets.

BES Sediment Testing Chart

HCID-TPH is a screen to determine the presence and type of petroleum products that may exist in water or soil. Table from BES 2010 Stormwater Monitoring Report referenced below.

What could be better?  Well, Portland monitors the effectiveness of its bioswales and some of the latest soil sampling data¹ shows that E-coli and heavy oil results were variable, but levels were higher than the background soil sample sites located nearby but outside of the stormwater facilities. Metal and PAH levels found in stormwater facilities were generally similar to those found in background sample soils.  While these results show that soils in bioswales are likely taking up E-coli and heavy oil from runoff that would otherwise go down a storm drain, soil results could be CLEANER THAN THE BACKGROUND SAMPLES in all categories tested: E-coli, heavy oil, metals and PAHs.  If mycelium running through the bioswale made the soil spongier and more absorbent and if those same mycelium could help the plants thrive by “eating” more of the pollutants, then I maintain we would have an even spongier parking lot.  A spongier parking lot could better utilize and clean the water running off it into bioswales.  As its trees and plants grow better with less pollutants in its soil, the spongier parking lot will decrease the urban heat island effect even more and become an important strategy for both mitigating and adapting to climate change.

I hope you will read my previous three short blogs on mycoremediation/mycofiltration (http://plangreen.net/blog) to better understand the technology I am proposing.  I plan one more mycoremediation blog on monitoring.

May 6, 2015, Portland, OR – updated May 18, 2015

It would be useful to read my Jan 2014 Mycoremediation: Cleaning Soils and Water along the Willamette River! blog in conjunction with this blog.

I was once quite active in the Oregon Mycological Society, but the need to be more focused on my profession of urban planning saw me let my membership lapse.  I recently renewed it and, to my delight, I’ve discovered a new wave of young members who share my interest in mycoremediation–using mushrooms to clean soils and water.

Dharma Rain Zen Center Mycoremediation Biobags

One OMS member,  Jordan Weiss, recently lead a workshop at the Dharma Rain Zen Center in NE Portland.  In the 2.5 years that this Buddhist group has owned this 14 acre former landfill, they have made a remarkable start to its ecological restoration as evidenced by the dried Himalayan blackberry canes lining the ravine that they are now planting in native plants and trees–and in mushrooms.

Jordan gave a bit of a lesson in mycology withan emphasis on white rot fungi because they are such fast soil-builders and because they are particularly effective in breaking down aromatic pollutants (toxic components of petroleum), as well as chlorinated compounds (certain persistent pesticides).  A number of species fall into the category of white rot fungi, including three that we dealt with at the workshop:  Oyster mushrooms (Pleurotus ostreatus) and Turkey tails (Trametes versicolor) and King Stropharia (Stropharia rugoso-annualata).

 

The below ground part of some mushrooms–the mycelia–have been shown to consume chemical toxins such as PAHs and bacteria such as E-coli.  Of the eight species of mushroom Paul Stamets team tested in an EPA funded study, “one clearly demonstrated resilience to harsh environmental conditions and a second showed promising characteristics. These species may therefore be considered as technically feasible for stormwater treatment applications. “

The below ground filaments (mycelia) of King Stropharia form a thick white net that filters pollutants and consumes them

The below ground filaments (mycelia) of King Stropharia form a thick white net that filters pollutants and consumes them

The most resilient species referred to in Stamets team’s study is King Stropharia (aka Garden giant).  Its mycelia form a thick web that would filter stormwater in the range of 0.07 to 0.10 cm/sec—roughly equivalent to medium grain sand.  So, the Stamets team judged it to be an appropriate filter media for meeting EPA specifications for stormwater management.  Workshop participants found King Stropharia growing along the west-facing hillside of the ravine at the Zen Center where  naturalized spawn on wood chips in a burlap sack was installed two years ago and fruited this spring.  After advocating mycoremediation with the City of Portland for over a year, it was great to see some land stewards actually doing it!

The workshop team then moved on to innoculating cottonwood logs with two species of white rot fungus–Turkey Tail and Oyster (but just one species per log).  This consisted of drilling some quarter-sized holes to a depth of about 0.7 inch, then scooping some mycelia that had been growing on cardboard into the holes and closing it off with wheat paste and a patch.  Jordan said that a best practice is to use inoculated sawdust and/or plug-spawn–but we were making do with what we had.

In his article, “The Petroleum Problem”,  Paul Stamets envisions the future of mycoremediation in Mycological Response Teams. These teams would consist of knowledgeable and trained people who would use mycoremediation techniques to recycle and rebuild healthy soil in the area. [1]

Jordan cautions that “fungi is a powerful tool in the remediators tool kit, but these and other nature-based technologies will not work if frivolously applied.”  He encourages us to familiarize ourselves with the ecological role fungi have in their natural environment.  I try to teach about such roles every time we see fungi on the Sierra Club outings that I lead.

In the Sttamets’ teams study, the second most successful species found to take up storm water pollutants with some vigor is the Oyster mushroom (Pleurotus sp.).  They grow in some abundance in nearby Forest Park–even in the winter with a hint of snow on the ground when only the toughest are out: English ivy, Swordfern and Douglas fir.  (Yes, I pulled that piece of invasive English ivy immediately after taking its picture!)

A Portland-based edible mushroom business produces Oyster mycelia inoculated straw as a by-product of its main business. The three recent college graduates who started this business have expressed interest in having their by-product used  in mycoremediation. Their straw is already becoming popular with gardeners and farmers and an important source of income for the business.

Along with Jordan Weiss, I am adding Mycoremediation to what PlanGreen offers.  I plan to work with Jordan’s Mushrooms and other businesses in the Portland area to offer a full range of mycoremediation services from design and planning to installation and maintenance.  We might start with Portland’s NW Industrial District. where students in the Masters in Urban and Regional Planning program at Portland State University are just now completing their project “Getting Green to Work in the NW Industrial District.”  We’re lucky that in the Portland area  green streets with bioretention facilities, green or eco-roofs, green walls, permeable pavement, etc. can now be considered  almost commonplace. This is the green infrastructure the students referred to when I attended their open house in April.  Right now, almost none of our built green infrastructure has mushrooms and their mycelia growing in it.  My team is proposing to change that.  If you have a mycology-based business in the Portland, Oregon area and want to be part of that effort, write me, Mary Vogel, at mary at plangreen dot net.

Mycoremediation: Cleaning Soils and Water along the Willamette River!

January 10, 2014

CentralReachImageIn a recent workshop the City of Portland, Oregon sponsored for its Willamette River Central Reach Plan , planners asked for habitat enhancement  “projects that would have larger bang for the buck”. . . “projects that would have a multiplier effect in terms of watershed health.”  Mycofiltration—the use of mycorrhizal mushrooms and their mycelia to filter pollutants would rank high on both of these criteria.

Mycofiltration will reduce harmful pollutants commonly found in urban stormwater runoff, such as heavy metals and polycyclic aromatic hydrocarbons, or PAHs. It also eliminates E-coli and other bacteria from pet wastes and waterfowl.  Because adding mushroom spores to remediation sites is very inexpensive and low-impact, it has the potential to be a sustainable option well into the future.

Report: PNWD–4054-1

In most places, stormwater runoff goes directly into streams, rivers and oceans and recycles through the watershed carrying the pollutants with it.  And that it is a big problem for salmon and wildlife survival.  Mycofiltration should be added as a treatment to enhance the activity of existing stormwater management biofiltration cells such as the rain gardens, bioswales and green streets that are plentiful in Portland. By adding Garden Giant (Stropharia rugosoannulata) mycelium to the soil mix, harmful substances that come from heavily trafficked roads such as I-5, I-84 and the motor vehicle bridges in the Central Reach: Broadway, Steel, Burnside, Morrison, Hawthorne, Markham, Ross Island can be transformed into carbohydrates and nutrients — which are actually useful to surrounding soil and plants cheap cialis overnight delivery.

By adding mycofilters to biofiltration cells installed in places where people walk their dogs such as South Waterfront, Riverplace, Waterfront Park, Eastbank Esplanade, etc., E-coli and other bacteria from pet wastes that were not properly disposed of can become a nutrient rather than a pollutant.  Having these mushrooms in the mix can actually help the native plants we are planting in streambank restoration and biofiltration cell facilities grow more robustly.  Instead of dealing with pollutants, their roots are getting more nutrients.

Paul Stamets TED Talk 2008

Paul Stamets TED Talk 2008

I was fortunate enough to meet inspirational mushroom guru, Paul Stamets (here he is giving a TED talk) when he was first starting his farm near Olympia, WA in the 1980s.  He had just wowed the Washington Department of Ecology with the use of mushrooms to clean up the E-Coli and fecal coliform problem caused by his farm animals.  In a single year he had achieved a 99% reduction in pollutants despite doubling the number of animals on the farm.

Since that time, I have gone on to found my business PlanGreen around using ecosystem services to deal with urban stormwater and other environmental problems/opportunities.  I believe, as Stamets does, that the Earth has its own immune system and that we need to learn to better work with that immune system. Although I have been excited about the efforts that Portland and other communities throughout the nation are making in biofiltration—using plants and soil to filter stormwater–I have long wondered why we were not utilizing mushrooms as well.

Fungi Perfecti Phase 1 Report

Fungi Perfecti Phase 1 Report

So, I was thrilled to see “Can Mushrooms Help Fight Stormwater Pollution?” as a link on the Oregon Environmental Council’s “Oregon Stormwater” listserve.  The story (first published on Sightline’s blog on Nov. 13, 2013 , then picked up by Public Broadcasting’s Earthfix) indicates that Fungi Perfecti is looking for partners to help further the research it did under a grant from EPA.  The study itself, Fungi Perfecti, LLC.: EPA Phase I, Mycofiltration Biotechnology Research Summary, concludes that additional research is needed to clearly define treatment design and operating parameters.

That sounds like a challenge that Portland area jurisdictions would relish. So PlanGreen is seeking to broker partnerships between Fungi Perfecti and receptive jurisdictions. Beyond treatment design and operating parameters, some of the issues to be resolved by those partnerships might be[i]:

  • Whether or not the mushrooms grown on decomposing toxic wastes are safe to eat.
  • To what degree of decomposition by mycelium of toxic soils makes the soils safe for food crops [including food for wildlife]
  • How economically practical will it be to remove mushrooms that have hyper-accumulated heavy metals. . .? Which species are best for hyper accumulating specific metals?
  • How to finance/design composting centers around population centers near pollution threats.

However, whether or not our cities, ports and other transportation agencies can qualify for the robust monitoring needed for the Fungi Perfecti research, we have enough anecdotal evidence (and PlanGreen and its partners have enough knowledge and materials) to get to the starting gate right now. As Stamets says in his book, Mycelium Running, “Now is the time to ensure the future of our planet and our species by partnering, or running, with mycelium.”
