III picnic organic

IMG_7246

uau!! what a day :) today we had a visit from students of Texas A&M University. we build together   our new model B, a structure to store the tools and give shadow to the composters (has other functionalities like bar :), there was also a workshop for kids about farm fauna and build “houses” for them and like always an amazing paella. please, if you are in barcelona don’t miss this picnics ever ;)

see you next month :p

II picnic organic

this is the second, expect one every month from now until the end of the summer :)

the picnic organic gathering organized by m.u.l.a and friends is where everything fits together. a bit like music where all the different instruments contribute to a common track.

in quirhort we have different teams that every 2 days feeds the composters and give a good turn to all. the composters are feed with neighbors organic waste and vegetables that this team gets from local shops. but before this organic waste goes to the composters, we separate what’s suitable to eat/cook/share and just then what’s left goes to hermetia illucens :)
part of this food gets frozen and is with this food that we make this amazing paellas for everyone that comes by this days and eat with us.

espai quiro farm containers II

 

uau, great day today!! we took apart pallets, cut some of them on strategic places, add screws , prepare some wood wheels and you get yourself a nice farm container :) all made with recovered materials from the surroundings.

next steppes will be building some more (will be dependent of the local-analog-crowfunding-campain that we are setting up:) and then apply our automatic watering system also made with urban trash ;)

will keep you posted :p IMG_6084 IMG_6086 IMG_6088

today we meet to start build the farm containers. this is our lunch on saturday :)

IMG_6089

we started early preparing the base of the farm container.

IMG_6086

and then move along cuting woods, take apart pallets and making weels. here you find a link of the farm container in our wiki.

composting at espai quiro

the idea is to start a group of urban composting, you know, we need to start making food for the vegetables :p

to start we’ll try 2 diferrent systems: a variation of berkley’s hotcomposting method and my friends Hermetia illucens 

for the hermetia illucens we will build composters from some old trash cans the the city council kindly gave to us. we’ll collect the leachate on a 1,5L pet bottle.

here some photos of the firsts gatherings.

espai quirò

back in april we made an open call in hangar to give a workshop. it did not go through cause we didn’t had enough people, but among the people who contact us was M.U.L.A. a beautiful collective project of house sitting, a DIT project made with both human and materials from the surroundings where old buildings are recovered by the people and supported by the proprietaries. we and MULA started to talk of making a workshop on the upper town and for us is great to have a project in this part of barcelona. MULA with other local entities are promoting the use of a vacant allotment where a old clinic (quirò) was taken down. they have an agreement with the city council for 2 years. it’s 3000m2 and more or less half will be available for urban farming. since we can not use the soil we’ll built farm structures with wheels for urban mobility :) apart of building the essential structures: shadow, composers, farm structures, watering systems, a kitchen :) we’ll try to go further this time and one of the tools we will try to implement is the local cartography of raw materials to build soil. we need to select composter systems and recipes to start mapping the leftovers of restaurants, citizens and other specific ingredient to then make the schedule of collecting. some tricks we can made like for example make a dropbox only to egg shells or sea shells. you know.. not only the local gastronomy is deeply connected with different vegetables for different seasons, the compost you can make in a city is also connected like this: here people eat “tortillas” and sea food and this are excellent providers of minerals.

we are starting a local-analog-crowdfunding to this project. check here the poster duna made. we have 3 kinds of farm structures, a starting party with food included and other surprises for the supporters :p you can support this project on selected places, like pepi’s bar, where she will explain to you and in person all the great things about this initiative and if you have time you can also know a little bit more about the neighbor and the surrondings supported by honest food cooked by pepi’s husband and the espai quiro blog webmaster, antonio.

the first design-together starts next sunday. we’ll meet in espai quirò around 11h. see you there ;)

fescamp 2015

this year we were invited by ciclica to give 2 workshops in fescamp. today I came with xavi to give our last workshop. have you ever been here? fescamp is a annual gathering that trough collaborative artistic practices promotes a critical reflection about the city of Sant Cugat del Vallès with focus on environment and sustainability.

we had a great workshop. many people interested in watering systems and e-trash recovering.

hope to see you there next year ;)

FesCamp15_9maig-v4.4_700

 

 

barcelona workshop open call and back home :)

has been 6 years and we now return to hangar.org after studying 15 different cities, different food, different tools and different trash. it’s good to be back home with a workshop program that’s the most comprehensive we’ve done so far. we also have other plans for the other days of the week so if you want to build together your next low budget automated food table just join us if you want to collaborate on the space building or on urban composting you are more then welcome ;)

 

 

Getting to know the Wooden Pallets

After some information from Hernani which opened our eyes to the world of wooden pallets, we realized that we were too naive to think that wooden pallets are just some wooden structure..

Wooden pallets can be spotted very easily around the neighborhoods and even in the city of Barcelona. There are a lot of ‘excessive’ wooden pallets that are thrown out on the streets and in the trash.

As a good result wooden pallets are often reused to make new things and it is playing a huge role as a material in the SUFj farm at IaaC. However we have to be very cautious of the selection of wooden pallets to pick up as they will eventually be the home of a lot of plants/food. Some of the wooden pallets have gone through some treatments due to some regulations and some of the treatments involve adding additives which are not desirable for gardening purposes.

I went up to the rooftop and took some snaps of the labels that can be found on the wooden pallets that we previously collected which I’m gonna show below (which some other labels that we don’t have) together with some information that I gathered from the internet :)

 

SAM_3245The logo on the left side of this label is the most common print found. In the logo there writes ‘IPPC‘ which means ‘International Plant Protection Convention’. This indicates that the wood has been treated by approved measures but doesn’t necessarily mean chemically. If you can’t see an IPPC stamp, it is not recommended for reuse.

On the right side of the label writes ‘HT‘, which means ‘heat treated’. It is a treatment where the wood is heated to the minimum core temperature of the specific to the wood type. There are no chemicals involved in this process this means it’s safe!

The code on top of the HT indicates the country where the pallet was produced and the code of the production. For example ‘PT-1218’ means that it’s produced in Portugal with production code 1218.

 

SAM_3244The label ‘KD‘ means ‘kiln dried’. This treatment is used to reduce the moisture content of lumber in a controlled environment (a kiln, for example) to reduce warping. Used mainly in the wood furniture and flooring industries. However this treatment can be done in a variety of processes. which means it’s not guaranteed that it’s fully safe.

 

MB

If it is labeled ‘MB‘, which fortunately we didn’t pick up any, it means that the pallet was fumigated with methyl bromide, a toxic pesticide. Pallet makers are phasing out methyl bromide, but you may still see this mark on some older pallets. Not safe!

 

SAM_3249The label ‘DB‘ means that the wood was debarked before it’s used to make the pallet. so Phew! means it’s safe!

 

EUREPAL

There are also two pretty commonly seen labels – the ‘EUR‘ and ‘EPAL‘. This means that the pallet is produced in Europe. Europe does not allow chemical treatment but it is only guaranteed fully safe if it is only marked ‘EPAL’. ‘EUR’ is from the old system so you might still want to be careful with it. The best is to find some with the both stamps.

 

SAM_3253Last but not least! There are some pallets which are labeled with color depending on the company that produced them. Blue pallets are produced by pool CHEP; Red pallets by pool LPR; Brown pallets by pool IPP. It is not advised to use them specially for gardening use as you may find traces of formaldehyde and other resins used in the composite blocks.

 

There are other labels which I couldn’t find what they mean which I hope do not relate to any treatment of the pallets. If there is any other label that you would like to add please let me know in the comment below so that we can have a more complete list! :)

MACBA lettuces

on the 12th of november I went with sebastian to give a small workshop about transforming e-trash in a automatic watering system. this workshop is inside a wider educational program made by opensystems to the macba museum.

we needed a small farm so that we could implement the watering system but the museum doesn’t have any farm or garden so we decided to design one, prepare all the pieces and build it together. this is the first drawing :)

IMG_0992 - 2014-12-08 at 10-15-54

so we need a structure that could be easy assembled and we had certain limitations: it must have wheels and it must fit on the museum elevators :)

so here are some pictures of the building process and at the end you have a pdf manual that we made to care and maintenance of the farm. you can also find documentation and the 3Dmodel on the wiki.

day#18,19 workshop @ iaac and fab10

apart from materials to make the farm structures we also need some more “tech” parts. today we went to solidança to get pressure switches, flow meters, water valves, water pumps, tubes and surprises that always come with the trash :)

next weekend we were invited to give a small workshop at fab10.org so we are also colecting extra materials.

2014-07-03 at 13-09-58 2014-07-03 at 13-23-39 2014-07-03 at 13-23-50

First week

I just arrived in Barcelona and I will start soon work in the watering system with arduino. Hernani already showed me many things and sent me materials to study and improve my knowledge, so I was “recycling” what I know about electronics and programming, now I’m doing the possible to update and get the system even better. Also, I’m excited for the project’s presentation at FAB10, on the weekend, will be a good opportunity to show the great work that Refarmthecity is doing and to gain more recognition.

day#13, 14 workshop @ iaac

busy day today :)

iaac rooftop

we have defined the form and start taking the materials to the roof.

during the last weeks we started collecting materials that are around us. here are some picture of what we found in and out iaac’s building

day#12 workshop @ iaac

ok. after 11 days of drinking knowledge and catch some potatoes ;) today we went hands on building the IaaC’s rooftop farm. first we went there and took some measures, look for sum exposition, orientation and imagine the space.

photo

then we went to the street, see what could we find arround the corner. we didn’t had to walk 10 meters. 4 10x10cm pine wood with no treatment just right in front of us :)

2014-06-12 at 12-51-10

also some wood pallets. we went to a chocolate milk factory tha’s arround he corner to see if they have one of thouse big food grade containers of 1000L. no luck it was closed like.. closed forever :(

then we went again to IaaC materials store. we knew there were many materials what we didn’t knew was how much!!

2014-06-12 at 13-11-25 2014-06-12 at 13-11-29 2014-06-12 at 13-11-33

after caring some materials and plan how to move everything up we went lunch with a friend of Xavi, Rosa Rull in Palo Alto. what was an old factory of flour and wool is now a huge forrest were the climbers have covered the buildings and there are bushes and trees all over the place. you see bees, people, birds and business all dialoging and their farm is exuberant!!

2014-06-12 at 15-52-04 2014-06-12 at 15-52-09 2014-06-12 at 15-52-44

what a great lunch (paella nham nham) we had together under the vines, the caper and complemented by indian cress flowers. tks Rosa ;)

1st Bokashi Batch

Hey guys, my bokashi system is more or less operational by now. After two weeks fermenting the papers in plastic bags, I laid them in the sun to dry. There were some air pockets in the plastic bags, which resulted in a few colorful fungi at some spots of the paper (I think Nestor had the same situation).

IMG_1448

For the composting tank I found this 8L bucket (including airtight lid), a strainer with a slightly smaller diameter, and plastic drain valve.IMG_1447 As you can see in the picture I already cut off the handle from the strainer, and dented the grid so it fits in a stable manner at the bottom of the the tank.2014-06-01_13-05-26_515Subsequently I made a whole at the bottom and screwed in the valve (optionally you can use some Teflon tape on the thread to make sure there are no leaks).2014-06-07_12-19-57_849So this what my ‘final product’ looks like. Time to start filling it up!
