Waste Management

Sewage Treatment

There are several types of systems that enable us to reuse water, by saving up to 80% of the total throughout the year:

    a)   Use of Wastewater
    b)   Recycling Greywater
    c)   Wastewater Treatment
    d)   Water decalcification and efficient osmosis

Water is a limited natural resource without which we can hardly survive for three days. Climate change and poor management of water resources, mainly, are decreasing the flow of our rivers and drinking water availability. It is necessary, therefore, to maximize the responsible use of freshwater.

Several methods for domestic water recycling can be used:

• Greywater Recycling: those from baths, showers and toilets
• Wastewater Treatment: those coming from toilets and kitchens
• Rainwater harvesting: accumulating and storing of rainwater collected from the roofs of our houses

In all cases, treated water is not directly drinkable but it can be used for applications that do not require drinking water. This way, dependency on external water is minimized because it should be used just for drinking, cooking, washing and showering . Other applications can take advantage of recycled water.

Biogas

Biogas is a combustible gas produced in natural environments or in specific devices through the anaerobic digestion or fermentation of biodegradable materials produced by micro-organisms in the absence of air .

This is a simple and inexpensive system that recycles organic waste both solid and liquid, turning them into energy and fertilizers for agricultural use. Biogas has a very high potential, because biogas cogeneration plants can be set up for networks of gas, electricity and heat supply for towns and cities.
