The Green Gap

In the Cold War, we feared a Missile Gap was a strategic weakness. Nowadays, we must awaken to the fact that the Green Gap is true strategic weakness: the nations whose economies will thrive in the coming years will not be those with the biggest factories, but those with the most sustainable, efficient, and ecological markets. What we require is a Strategic "Green Reserve" of ecological design to weather the coming changes that both climate and resource scarcity will force on the international economy.

Mycelium Running... for real this time.

I appear to have had some luck running mycelium in coir and wood chips lately. See the above three jars filled with bits of happy mycelium? They are from left to right, pure-ish coir to mixed coir and wood chips. So far it seems like the rightmost mixture is the happiest, though it could also have something to do with the fact it appears to have retained a little more moisture than the others. The pure-ish coir jar seems to have good, fuzzy mycelium in it:
Whereas the one in the mason jar seems to have developed some other form of mould to compete with the pleurotus ostreatus. Perhaps a holdover from its days holding other foods and not being as thoroughly cleaned as it should have been:
If I had supervision of any kind at this time, I might be forced to throw it out, but I really want to see just what happens... and if it goes rank, I'm putting it under the microscope, by gum!

The black soldier fly is doing well. They are crawling off a lot nowadays, so I hope we are getting an increase in the local population. I am not yet ready to start collecting them as I have nothing to use them for. If the neighbourhood allowed it, I would have gotten a chicken or something to et the BSFL, but I think they are going to have to go into an aquarium of fish eventually as fish food. They eat bloody fast though and I'm alone in the house now with dwindling amounts of food to give them. I had a bunch of people over last night, so we had some scraps, but I can't well have a party every night just to feed my BSFL. 

Then again, I suppose I could, and it would be pretty awesome to have a maggot-themed party, I'm sure.

Lastly, I've ordered a vericomposting kit to compost the castings of the BSFL into some friable compost. In order to keep moisture in the indoor food collection bin down, I've been putting dustings of coir in the bottom. These are slowly building up in the BSFL bucket as the BSFL can't really eat coir. After a good soak in the bacteria-rich goo that the BSFL leave in the bucket, it should be soft enough to be able to be eventually digested by the worms I hope. Also would like to plug the vermicomposter's designer, from UFO  (Urban Farms Organic). Check out their designs for high-volume modular composters. I will be reporting back to UFO on how they work out here in the tropics on BSFL leavings.

That's me up-to-date, more news as it happens...

Black Soldier Fly

I've been trying to attract black soldier fly larvae (BSFL) for some time now. First, I started with rotten coconut. That dried out, moulded, and ended out nasty and disgusting. I then tried reconstituting corn, putting it in the coconut to rot, and attracting BSFL that way. The corn moulded and ended up not being colonised. Finally, I had some old cabbage pickles that were going rancid in the fridge. I put those in the coconut and kept them wet but under a cover. After a week or two, I spotted what I believe to be BSFL. since then, I've gotten a bucket and started feeding them outside the coconut. While they've not completely colonised the bucket, they are slowly eating our biodegradables. See disgusting picture below :) (the BSFL are the white things in the middle of the bottom third of the picture)

Of course it doesn't disgust me, I'm the proud father of highly useful maggots :)

No Such Thing as Garbage

Calgary's budget (2009-2011 business plan) is divided into the following parts (each of these numbers is net budget taking into account both revenue streams and overall expenditures):

Asset Management & Capital Works  (public works, fleet management)
$35,858,000

Community Services & Protective Services (EMS, Fire, Parks, Community services)
$3,121,300

Corporate Services (the personnel who keep IT, customer service, and the books straight)
$115,292,000

Planning, Development & Assessment (land use planning and development)
$34,772,000

Transportation (Calgary Transit and Road infrastructure)
$278,740,000

Utilities & Environmental Protection  (garbage, recycling, and water)
$42,297,000

Calgary Police Service  (you get the idea)
$243,175,000 - 2009 budget

Corporate Administration (the people who run the city and bylaws)
$21,026,000

Right now the main budget line I'm interested in is the Utilities and Environmental Protection. In effect, I'm proposing it ceases to exist entirely. Well, perhaps not water, seeing as it generates $60M overall revenue per year, but garbage and recycling services. These services do generate some revenue, through landfill fees and recycling and the like, to the tune of $82,238,000 in 2009. This acts to offset (along with some $11 million in recoveries) the total of $128,640,000 in gross expenditures on waste disposal and recycling services.

All this to say that garbage collection is not a total loss. $82 million is hardly chump change and those revenues and more are still available to the Calgary city economy if the ideas I'm going to talk about are adopted. I simply believe that the disposal of waste is idiotic when every ounce of "stuff" that normally ends up in a landfill can be returned to the economy. The more we start thinking of garbage as an input rather than waste, the more money everyone stands to make. The idea of making effluents and byproducts into "industrial nutrients" are of course core to McDonough and Braungart's Cradle to Cradle, and dealt with in Natural Capitalism. I'd like to make a slightly more concrete recommendation that could be initiated on a five-year window to increase jobs and save $42 million from the city budget. Let's not forget that the money also implies FTEs, that's government-speak for "full-time equivalents" - people. The waste management stream of the city government employs 574 FTEs, going to 610 FTEs this year. Those people have to be taken care of, or the elimination of this budget line would have to be considered a failure.


First priority, then, is to inform the people working for Calgary's waste management that their entire section is to be spun off over the course of 5 years. Each employee should be given a five-year guide explaining exactly what changes are going to take place and what opportunities they will have in the course of these changes. During the course of the change, the population of Calgary will have to be kept informed of the new methods for garbage and recyclable collection. In effect, the effort of garbage and recyclable collection is going to be decentralised and handed over to numerous independent operators. They (and their competitors) will negotiate to the population in their area to determine the best means to effect garbage collection.

The process would have to be people-oriented, and strive to meet the highest standards of transparency in order to work. Business thrives in environments where there are controlled risks. There has to be risk to make a margin, but not so much risk that the margin is constantly in doubt. Transparency regarding the process of transition must be complete and unburdened with the rarified language of bureaucracy. The plan would move through the following phases:

1) Research
The City government will engage business planners, designers, and policymakers in formulating some basic business plans that may then be verified by the Business Development Bank of Canada (BDC). The basic need in this phase is to formulate the regulatory framework that the new waste management system will evolve in (bylaws and instructions to the Calgary population regarding how and where to sort and set out their household garbage). It will also be good to identify several basic business plans that might survive and thrive in the new regulatory environment so that early buy-in by participants is easy and relatively painless.

2) Engagement
The City will then go to its waste management professionals and offer them a view of how the system will evolve over the next five years. With the assistance of the BDC, the City will assist early adopters in receiving financing. Calgary will purchase or provide insurance on the loans in order to make the option more attractive and less risky. The largest loans should be reserved for the group of waste managment professionals who opt in in the first year. The number of opt-ins in the first year should be artificially capped at 100 so as to avoid strong competition, and to avoid flooding the market with too many services. When a city employee opts to take a loan, and either adopt a pre-existing business plan or make his own, he will be granted an area of the city in which to start his operation that is a reasonable distance from competitors. He will not have exclusive rights to the area, but City of Calgary will agree to withdraw their competing services from that area. In the subsequent years after the first roll-out of new services, new services will be able to piggyback on the infrastructure and best practices of old and established ones. For instance, if Bob opts-in first year to collect cans in a region of town for resale to a foundry, Jane may be able to hitch a ride in his truck when she establishes her bottle-collection business in the same area. Horizontal integration of these collection services will, over time, reduce costs all around and necessitate lower and lower opportunity cost to buy in.

3) Market development
From day one, the City will be engaged in developing markets - preferably local ones - for these business activities. In participation with the BDC, composting and vermiculture units could be established, black soldier fly processing companies started, or glassworks constructed. By creating a market for lawn clippings in the form of biochar, perhaps mixed with worm castings, the City will encourage the establishment of the gasification plants that can produce that biochar. The city itself - for instance, in parks and recreation - can create a market for compost tea and worm castings for its gardening work. An office in the city could be established in order to subsidise the purchase of these products through creating easier access to carbon sequestration credits.

As the plan progresses, the initially risk-averse should slowly be able to rationalise a start in a new business. Those who would prefer to leave the industry can be given a simple golden handshake. In five years, this budget line will have been removed, but by saving $42 million, the city will be creating milions more dollars worth of jobs fuelled by waste. The economic knock-on effects are staggering to consider: all of this stuff that previously had no value and left the market will be given value again. Ingenuity and entrepreneurialism can create new industries within this market that will fuel a new period of export creation and import replacement. By turning this industry over to the private sector in a humane manner, everybody benefits.
