Cyclers is a system that seeks to make the most out of water usage, through the application of nature�s principles, such as composting and use of natural energy sources, such as sunlight and gravity. These natural processes help in the collection and semi-filtration of rainwater through plants, using UV filtration systems as a support.
The system follows the next steps:
1. Food waste collection generated during the preparation of food
The system considers the implementation of mechanisms or elements that facilitate the separation and collection of organic waste coming from the preparation of food in individual apartments
These elements are designed bearing in mind the way in which people commonly prepare their food, and dispose the waste.
Some info that supports the relevance of this problem is:
· 69% of world water is used in agriculture ("WBCSD Water Facts & Trends". Retrieved 2011-20-11.)
· In developed countries, close to one third of the purchased food goes to waste. ( �Global food losses and food waste�. Retrieved 2011-11-29)
2. Composting and collection of water coming from the composting process:
At this stage, all the organic waste of the building is composted, using the heat from the sun to accelerate the process (�Composting�. Retrieved 2011-11-29).
At the same time, all the liquids generated during the organic waste composting process, which are located at the bottom of the container due to the action of gravity, are collected. This liquid is mostly the water content of foods, which in the case of fruits and vegetables can represent up to 80% or 90% (�Water Content of Fruits and Vegetables�. Retrieved 2011-11-29)
The proper use of this particular kind of waste can help in avoiding the pollution of water, due to the excess of nutrients contained in it. (Eutrophication)
3. Use of compost in the building façade and interiors.
When compost is used as soil for growing aromatic plants, fruits, vegetables or ornamental flowers, nutrients from the composted waste go back to their natural cycle, allowing us to make the most out of this natural process.
Closing the natural cycle of waste in the same place they are generated is relevant, because it helps in reducing the impact caused by CO2 emissions associated to the transport of waste to the landfills.
4. Rainwater collection and semi-filtration:
Taking advantage of the leaves� geometry, which is especially shaped to enable the effective collection of water, the plants located in the façade will help collect rainwater, and filtrate it through the soil and roots thanks to gravity. This semi-filtered water can then be stored.
5. Ultra-filtration process
The ultrafiltration process works passing water �that has been obtained from composting and rain - through a filter, using pressure to eliminate existing particles in suspension. With this process, a filtration of up to 0.3µ can be achieved, removing viruses and other unwanted particles.
6. Re-use of water
The water is pumped to the apartments, where it is intended for use in bathrooms and plant watering.
