A solution pure and simple

ECO-TEC’s PET-bottle building initiative was born in 2001, in Honduras. After three years of testing and improving our method, we began to offer training programs on our technique to transform used plastic soft drink bottles and construction waste into architectural structures.

We developed over fifty PET-bottle projects in Bolivia, Colombia,Mexico,Uganda, Honduras, and India, in cooperation with rural and Afro-Latino communities, vulnerable communities in urban contexts, as well as disabled persons, university students, local government personnel, and NGOs. ECO-TEC assisted communities in establishing recycling infrastructure and utilizing the collected waste in the construction of bus stops, kiosks, water reserve tanks, retention and protection walls, vertical gardens, and houses. We also participated in the effort to recuperate public space through the construction of eco-parks. Through hands-on participation and discussion of the social, economical, and ecological impacts, these communities now see the products of recycling as valuable commodities that can improve lives when utilized in building houses and other community-enhancing structures.
ECO-TEC’s primary goal is to educate more people in the social, economic, and ecological benefits of utilizing PET bottles and construction waste for building. We need to build training centers that will allow us to implement a larger educational program.

Renewable Energies in Uganda

In Uganda, cooking does not mean simply turning on an electric stove. Over 90 percent of the population use traditional stone ovens and are therefore dependent on fuelwood, charcoal or agricultural waste products. As no alternative fuels are available to these people, the volume of wood consumed in Uganda is enormous. Entire forests have already been destroyed. Women and children, traditionally responsible for cooking, have to go further and further afield to collect fuel-wood. Furthermore, the effects on their health are severe, as the intense concentration of smoke from the stone ovens inside the huts frequently causes chronic eye and bronchial disorders.

To counteract these effects, Vianney, Emma and many other individuals and organizations are promoting modern energy services for the Ugandan population. The aim is to supply the poverty-stricken population in Uganda’s rural areas in particular, only three percent of whom currently have access to electricity, with modern and sustainable energy technologies in the future.

Energy from Biogas is one option Ugandans can exploit, its made by decomposing without oxygen organic material in a digester.
Below is a digester made from 2 plastic tanks, one inserted into the other.

A biogas flame!


After harvesting the gas, we also get organic fertilizer, so the plants get healthier.
