Micro-devices and Prototypes

R-Urban has prototyped a series of ecological Micro Devices  for the Recyclab and Agrocite Units. These micro-devices for power generation and food, water management and organic waste are realized from local materials and with simple technology. They are supposed to promote innovation within the reach of citizens.

This heating system recovers and reuses the thermal energy produced by the compost during the biological process. At the heart of the volume of 1m3, the temperature can reach 60 °. In this iteration the system will serve to heat all the buildings of Agrocité during the winter. With this experiment parameters , which remains largely understudied in world .

Hydroponics (or soilless agriculture), is the cultivation of plants performed on neutral and inert substrate (sand type pozzolan, ball clay, rock wool etc.). We added to the system a filtering vessel in the path of the water. The advantage of this system is that the drainage and replacement of water are no longer necessary, since the operation is closed cycle. thanks to the biological filter, water nutrients throat with each pass and thus continues to be able to feed the plants.

The “window farming” is the latest evolution in the field of sustainable production of short-cycle food. This movement, initiated by the New York Britta Riley, is a way to produce food using a simple but effective system in urban environment. This serves plants contained in a recycled plastic bottle. Easily available, great waterproof and contoured shape fits particularly to a vertical flow system. Transparent, thin plastic, it lets the sun and acts as a mini greenhouse for plants.

Green Wall, Green Roof & DRIP IRRIGATION

The building has a green vertical garden on its east and west facades as well as on its roof. Rainwater irrigates the roof and the drip system is employed for the walls and rest of the plantations. This system has two sources of water. The first comes from harvesting rainwater stored under the building in a storage basin. The second source of water is water in the city. It comes from a tap located at the mezzanine. Both are used for the garden.

Water Phyto-filtration

The system presented is the “Jardi-assainissement.” Household grey water from the shower and kitchen are collected and then injected into the filter. The filter is composed of two planted beds arranged in parallel, which alternatein usage per week. The filter is planted with macrophyte rhizomes, whichpromote bacterial activity to consume pollutants; purifying the water, which isdischarged to a planted infiltration area and then the ground natural.

Smart Irrigation

schem smart ir

The smart irrigation system is operated by a network of microprocessors which “think” and “decide” then the plants need to be watered according to information from its moisture sensors, rooted within the soil of the plants. This system means that little to no human intervention is needed, creating an autonomous vertical garden. Once activated, the water is pumped from a rainwater storage tank and distributed via drip irrigation.
