RED 2 Meeting 5 – November 21, 2010
In attendance: Evelyn, Lea, Michelle, Vantar
For our final slide presentation we need to cover 20 minutes. That’s anywhere from 80 to 120 slides, if they stay up for 10 to 15 seconds per slide respectively. Each one of us will focus on ‘answering a question’ (you’ll see what I mean when you keep reading) and we’ll come together next Tuesday, November 30 at 7:30 pm (please eat dinner first) in the studio to put it all together and go from there. Create slides using the suggested layouts below in whatever program you can and we’ll put it all in keynote at the meeting.
Cycle of slides will be as follows:
TITLE > FACT > QUESTION > ANSWER > FACT > QUESTION > ANSWER … until we answer all questions
Main question: WHERE WILL YOUR DINNER COME FROM?
Other Questions (not yet posed in question form):
Since Don suggested we get rid of the history section, we will use any necessary facts in the FACT slides that pertain to posing a QUESTION and then we’ll ANSWER it.
THE NEXT STEP:
Please keep in mind that all slides should focus on our NARRATIVE, supported by your research; they are not slides OF your research. Also, if your original research doesn’t seem to fit into our narrative, don’t be reluctant to let it go.
Facts: Natalie and Kate
A: Alex and Evelyn
B: Stephan and Paniz
Final Layout: Kate
Our end goal is SUSTAINABILITY and not zero waste. Zero waste will be taken care of in the waste section.
Please voice any concerns at our next meeting and let us know if you cannot make it.
THE GOAL: WATER FOR IRRIGATION
THE ELEMENT: THE MEMBRANE BIOREACTOR
Used in existing urban applications:
The Earth Rangers Centre, see http://my.cagbc.org/database/img_489c7680afef8.pdf(accessed November 9)
The Earth Rangers Centre is a wildlife facility that has implemented many 'green' aspects into the daily functions of the building. The membrane bioreactor that I speak of is used here. They use the ZENON brand. The water that they get from the filter doesn't seem to be good enough for drinking because they use it for applications such as toilet flushing, cleaning floors and cages, and filling waterfowl ponds. They also get extra water from collecting rain water from the roof. By using rain and treated water (treat on site) they save from using drinkable water. The LEED Consultant in this project was Enermodel Engineering and on their site,
Earth Rangers, they also discuss the wastewater treatment used at Earth Rangers, a bioreactor and ultra-filtration system.
<--example for presentation of final
Other locations recycling water:
In this article of Financial Post, examples are given of communities who use a "grey-water reclamation system", like Quayside Village in North Vancouver. Other locations, like St. Petersburg, Florida actually collect grey-water from houses and reuse it for irrigation. This is definitely something we should consider and employ in the water cycle aspect of our kit.
Companies offering this treatment system:
This is what they offer: "ZENON Environmental, now part of GE Power & Water, continues in the tradition of being a global leader in advanced membranes for water purification, wastewater treatment applications including membrane bioreactor (MBR), tertiary water filtration, drinking water treatment, industrial process water and water reuse. ZENON’s technology solutions are part of GE’s leading portfolio of advanced water equipment, chemicals and services."
What it is:
A membrane bioreactor can be used in a home to treat waste water to be good enough quality to be used for irrigation. As Vantar has eloquently explained, bugs in the filter eat all the 'solid waste' and clean water comes out the other side. More on feasibility and maintenance of this unit soon.

Here are some options
They are the easiest to farm in the city, anyone can do it. Chickens provide both meat and eggs and they eat kitchen scraps (this reduces waste) Their manure can be used to make a “tea” which is a good fertilizer (it can't be used 'raw' because it's too high in nitrogen.
There’s a great video on a chicken coop designed for use on patios and terraces, so you could even keep 2 or 3 chickens in a high-rise apartment
This is an interesting article in the New York Times about people keeping chickens in the city. It talks about some of the problems (it’s illegal in some cities) and advantages, and mentions several websites for city-dwelling chicken owners, including The Chicken City (http://home.centurytel.net/thecitychicken/index.html) which is a great site for anyone who wants to raise chickens in the city; lots of information on breeds, coops, issues that may arise and how to solve them. Most of the information is for people who want to keep chickens in their backyard, focusing on chicken tractors (portable coops), but I also found the link to the above terrace coop on this site. Lots of great pictures
The manure undergoes an anaerobic digestion that produces methane and carbon dioxide which are then burned to make electricity. This produces heat. Any kind of manure (chicken, cattle etc.) can be used, and the manure can still be used as fertilizer after the digestion.Currently, they used only on large farms, but they could be adapted for residential use

RED 2 Meeting 3 – November 7, 2010
- Urban Green Kit
- historical background that drives urban agriculture
- concepts already done
- the kit:
- angled garden plot
- bee hives
- domesticated pigs: waste management, heating, compost, fertilizing
- rain water collection: watering plants, flushing toilets
- heating/cooling with rain water
- grey water reuse: watering plants
- **picture, circular diagram, (cycle sustainability and zero waste: Evelyn – youtube example)
- concentrated agriculture within an urban environment
- elements that can be applied to any urban space
- natural water treatment system
- drip irrigation
Who's covering what topic:
Lea: residential agriculture: interior
Stephan: concentrated urban agriculture
Vantar: water cycle, reuse
Natalie: land for agriculture
Paniz: residential agriculture: exterior
Alex: residential agriculture: portable
Evelyn: residential agriculture: interior
Michelle: water, treatment
Next meeting, Tuesday 7:30
Email everything to either Evelyn or Paniz: firstname.lastname@example.org or email@example.com
I think this illustrates the message we're trying to get across.
The following website reports on a green block competition in Dallas. There are projects of the three finalists and incorporate the ideas we discussed such as rain water collection, vertical farming, community garden, roof top live stock enclosures and more.
There's an article on The City Farmer about the gardens in Berlin. Probably the most useful information in the article i had on is a list of the benefits of having these gardens. They include: having a cooling effect on the city's climate, and filtering harmful particles out of the air, providing a refuge in the middle of the city for many species of birds, insects and wild plants, providing children who live in city-center apartments a chance to experience nature, offering a healthy and cheap way to get some exercise, and, maybe most importantly, allowing food to be grown near where it is consumed, thereby reducing climate damage caused by having to transport it over longer distances.
|Schwägerl, Christian . "Popular Mini-Gardens in Berlin May Soon Be Paved OverSpiegel Online". (10/15/2009), http://www.spiegel.de/international/germany/0,1518,655343,00.html. (accessed November 7, 2010).|
We could look at areas of small individual gardens, or one larger community garden. An interesting idea is for businesses to have community gardens for there employees. ex. Intel’s Jones Farm campus in Hillsboro
I think we should also look into some kind of a greenhouse so the garden can be used year-round
Lea Koch, Nov. 7, 2010
RED 2 Meeting 2 – November 3, 2010
Quick summary of the relevant topics in what each person found:
Alex: urban agriculture, angled plant boxes on buildings
Lea: garden in city, city farmers
Stephan: agriculture, fish farmer, linked to volcano explosion, increased plankton, more fish, returned, fertilization; swine flu: killed pigs in Egypt, waste management issue because no more pigs, potential for natural waste management system

Three topics will be:
Secondary: WATER, WASTE
Goal: To create a space, focused on agriculture, waste, and water in which we can apply our urban survival kit.
The next step: Go back to one of the entries you had, and pull out any elements and/or citations that we can apply to a space that will be a full manifestation of our urban survival kit.
Next meeting: Sunday, November 7, 2010. 6:00 pm. Meet in studio after handing in Project 4.
