Frequently Asked Questions



Participate in conferences and training environmental consultants with a focus on solving the problem of solid waste. In the implementation of micro projects and advice to communities and government agencies. We have experience in Ecotourism and have worked with many vulnerable communities in different countries, including people with disabilities.

You can use many more materials, the important thing is to have these materials as waste and in sufficient quantities to build a work. We have experimented with small wagon wheels and trucks and it went very well, welding sills and corners with these old wheels.

In general we can say that it is a bioclimatic design, which means that when it is cold outside is hot on the inside and vice versa. Very much like the adobe.

If you can, and we did in 2005 in Honduras. Forming a dome and using small bottles without filling the bottles.

If you can and have done so. The largest tank in which we participate as a business engine that has capacity of more than 20,000 liters. To date, we know of about 10 built tank with a capacity from 3,000 to over 20,000 liters.

To date we have no studies that confirm our experience, but we are negotiating with the Free University in Bogota a study. What can be said is that the oldest work, a house made of bottles and without cement in the walls we built in 2002 and although this house supports a 30-ton green roof has no structural problem. Like the 15 houses and water tanks until December 2007 we have built.

Normally we can say that low building between 40% and up more than 50% compared to traditional construction price, depending a bit what kind of work we are building.

In general you can use all kinds of plastic bottles, the secret is to have enough to finish the work. You can use different bottles in a work but not to mix in the same wall.

In the equine use 0.5-0.6 ml bottles in a circle of 11 bottles. In the middle tied the twine or nylon peaks. In public works use the same mixture 1:6:0.5 (1 cement 6 sand and half of lime), but we also made using earth houses at the corners named pillars.

Sisal or nylon is used typically used in agriculture. On the walls every bottle tied to each other as by a network, with lids and a tie at the base of the bottle. The base is attached with going around the loop, when placed. The peaks or tops also are given a turn and intertwine with each other in a triangle shape (see photos of the works)

On the walls we typically use a mixture of soil with clay / mud very similar to the land of adobe, you can add rice husk or grass but not so important. Every 4-6 courses use a mixture of lime and cement to avoid problems if built in the rainy season. The mix is ​​1 cement 6 sand and lime 0.5. If you do not have sand, you can do the same mixture using soil to 1: cement, 10 of land and 0.5 of lime.

Generated using a funnel with a PET bottle of 1.5 or 2 liters at which we cut off the part of the base. Then use rubble, earth or sand casting, or mesh strainer, used in construction. The important thing is that the drier the material easier to fill the bottles.

We always use local materials, which means that in the cities used in the field debris and dirt or sand from the river.

Consultant charge per day $ 500. But depending on the work and time can go up! We teach a training technique and each ends in a play. All these works are done in self.We are also in the micro environment and have experience with different types of vulnerable populations.

The technique was invented by Mr. Andreas Froese, of German origin and development in Honduras this technique built in 2001 and since the date has performed over 50 different works in different countries.
