- Buried Aymarian Greenhouse + (The Granja Ecológica Ventilla has an organ … The Granja Ecológica Ventilla has an organic label. Their fertilizer is a mix of compost, cow-pat and lombric(?)-based compost. 8 cows are raised for cheese production and cow-pat for the fertilizer. Their healthy diet consist in plants which grew flowers in the greenhouses, cereals bought on the market (barley), and vegetal residues from a local beer factory. The plants are pollinated by bees from the beehives. The irrigation is made manually every day. The water comes from a pool where rain water is collected. The heat from the greenhouse could be propitious to disease propagation. This is why it is necessary to control the soils and the plants frequently. The vegetables are conditioned in a cold room (the coolness is kept thanks to 60cm-wide walls) under high sanitary standard conditions. Every morning, the vegetables are washed, let dry on nets, sorted, packed and tagged before being delivered on local markets.

====How to manage the refrigerants ?====
Les fluides frigorigènes contenus dans les réfrigérateurs peuvent avoir un fort impact sur l'environnement. Ils ont un '''fort potentiel de réchauffement climatique''' et, lorsqu'ils contiennent du chlore ou du fluor, ils participent à la '''déterioration de la couche d'ozone'''. Pour connaître le fluide contenu dans votre réfrigérateur en l'absence d'étiquettage, un repère simple est sa date de fabrication
(according to [https://aida.ineris.fr/consultation_document/30790 Règlement Européen F-gas 517/2014]).
*'''If it dates from before 1995''', it probably contains chlorofluorocarbons (CFCs - fluids R11 and R12), whose global warming potential is up to 10,000 times that of CO2. CFCs have been banned in the European Union since that date.
*'''Between 1995 and 2010'', the mainly authorised fluids are hydrochlorofluorocarbons (HCFCs - R22 fluids), whose global warming power is up to 2000 times that of CO2.
*'''The period 2010 - 2015''' corresponds to a transition period during which the manufacture of new equipment containing HCFCs is prohibited. In 2015, the presence of HCFCs in equipment is prohibited.
*'''If built after 2015''', it may contain :
*hydrofluorocarbons (HFCs - R134a) whose warming potential is 1,500 times that of CO2. These fluids will be banned in new equipment from 1 January 2022.
*Hydrocarbons such as isobutane (R600) and propane (R290). Their contribution to greenhouse gases corresponds to 3 times that of CO2. There is no legal restriction on their point source release into the atmosphere.
*Other fluids are being tested, such as CO2 or ammonia (NH3).
To avoid releasing these gases into the atmosphere, several solutions exist:
* Collect a refrigerator grill from an approved organization for their decontamination.
*Make a circuit to capture heat from other materials. [https://www.instructables.com/id/Solar-Water-Heater-From-Scratch/ This tutorial] allows you to make one from copper tubes. You can also use a black pipe as in [https://www.youtube.com/watch?v=3rij58j_tvg&feature=youtu.be this video].
====Why separate the double glazing ?====
Each pane of glass reflects some of the radiation. The choice was therefore made to lose insulation in order to gain thermal input.
====What is the danger of legionella contamination?====
The solar thermal panels are associated with an exchanger tank which has a resistance to take over during periods with less sunlight. This ensures that the minimum temperature required to kill legionella bacteria is respected: these bacteria responsible for legionelosis stop reproducing at 55°c and die at 60°c.

In temperate zones, they appear spontaneously in moist composts (containing a lot of fruit for example) from a certain temperature.

It is possible to place the water collector in a colder area to reach the dew point more easily, e.g. on the outside of the door. ====Material supply==== Steel wool can be found in a machine shop or on some sponges. Concerning the compressor, it is possible to do without it (as described in the tutorial), or to use one for refrigerators. ====Self-sufficiency==== The tutorial on a semi-buried digester of Hélie Marchand in Madagascar ( [[Biodigester]]) will give you more information for a larger scale biogas production. To have an idea of the dimensioning of the system to be set up, it is necessary to count on average 1kg of waste producing 1 half hour of gas. ====Alternation with other gas sources==== To supplement the gas production, you may want to use the stove with other gas sources. If the stove is connected to city gas, it is easy to add a three-way gas valve, to which two inputs (biogas from the biogas plant and natural gas from the network) can be connected, which can be opened as needed. If the gas stove works with propane or butane cylinders, in this case the injector must be changed to adapt it to the gas used: methane requires a G20 type injector, while cylinder gas is used with G30/G31 injectors. This is feasible, but it will be difficult to change it every day. ===References=== *The first edition of this tutorial has been realised by Clément Chabot, during the Biodigestor stop of the Low-tech Tour in France. *The documented solution was realized with Pierre and Thomas from the PicoJoule association http://www.picojoule.org/ [http://www.picojoule.org/] https://www.facebook.com/Picojoule/?fref=ts * Bernard LAGRANGE, Biométhane 1.

====Utilisation de l'urine comme fertilisant====
1L of urine contains on average 6g of nitrogen, 1g of phosphorus (directly assimilable) and 2g of potassium. Nitrogen is in the form of urea, which will be transformed into ammonia on contact with the air. It is this step that produces the odor associated with urine, but it is eliminated by the action of micro-organisms or by storage without contact with air.
Plants are able to assimilate nitrogen in two forms: ammonium NH4+ and nitrate NO3-, with a preference given to nitrate in most cases. The biofilter enables this transformation.
Il est important de diluer l'azote pour éviter une concentration trop forte en sels.
