Building Manual
a collaborative project to foster home composting
Compo-station
Behind the Project Germany, Poland, United Kingdom, Sweden and Mexico come together to work on an art project and Mexican-European sustainability. European and Mexican artists promote positive changes in the social, urban and environmental contexts in their countries through cultural exchanges and artistic projects. The project’s main premise is to exchange knowledge, ideas and practices in order to explore how the art can serve as a catalyst to achieve positive changes in society, urbanisation and environment. The workshops includes disciplines such as design, performing arts and sound art. It is supported by artists from Germany, France, Mexico, Poland, the UK, Sweden and Spain. The workshops are designed to raise awareness and encourage people around, share responsibility of the environmental problems and participate in creative solutions.
The event is called RE-MEX. The Power of the Arts highlights not only its artistic proposal, but also shows commitment to a social cause when looking for empowering workshop participants through the development of skills and trades. This time the Goethe Institut of Mexico, calls the Mexican designer Ariel Rojo, who is leading a collaborative project with industrial design students from the UNAM (National Autonomous University of Mexico) and staff of El Faro de Indios Verdes. The aim of the workshop is to learn the technique of vermicompost from organic waste. The result of this collaboration will be CopyLeft design, which will be offered to anyone from around the world who is interested in assembling this piece and contributing to the environment.
The vermicompost allows converting organic waste into compost rapidly, while producing high quality fertilizer. The compost maker is made of three buckets of 19Lts cut at 3 different heights creating 3 levels. The first level is the fresh waste coming straight from the kitchen. The second level is a transition of organic waste (where the worms are), and at the bottom is the humus. The third level holds an accumulated leachate, which is the liquid from the process, and which has also great value as a fertilizer.
The workstation is made of standard sized pieces of lumber and of 12mm plywood. The result of this project is the compost and the workstation. Generally composting is inconvenient, but this proposal offers an optimal workspace for chopping organic waste and keeping some of the gardening tools that are linked to composting.

Compost - Assembly 1. Prepare three plastic buckets of 19 liters, 2 of which must have lids. Cut the base of bucket 1 leaving a tab of 2-3 cm, this will serve as a base for attachment with Lid 2.
2. On Lid 2 cut a circumference taking as reference the hole previously made on bucket 1, this will create a support frame.

Use your compo -station Finally you're almost ready to use your Compo-Station. Simply place the buckets on the brackets of the structure as shown in the image to get started.
set up your Compost-Station .
Fill the bucket with strips of cardboard or shredded newspaper. Also add dry grass or something similar to it so that it is well ventilated. Add a
handful of earth on top of the above and let it wet. Let the water seep well one day before introducing the worms to Compo-Station.
get worms Hay
There are many varieties of Vermiculture worms. Therefore, it is not advisable to take just any kind of worms that live naturally in gardens. It is best
to go to a gardening store to learn which is the the variety of worms that handle most convenient for you.
collect compost Once enough time has passed * for the worms to work the compost, you can rotate bucket 3 and align the openings to collect compost. Use rubber gloves. Remove the compost and place it on a Station. Un
newspaper, then spread it in layers to identify worms that might be left in the compost. Separate them and return them to the Compo-Station.
use your compost Now you can plant using your rich worm compost, and do not forget that with the composting process, a leachate at the bottom of Compo-Station
is left, which likewise can be collected and be used to fertilize your crops.
* Usually compost is considered ready after 16 weeks, although the product can be used in outdoor gardens at 6 weeks where it can follow the decomposition process with no negative environmental impact.
