Look at this great way to recycle bottles and cans in earthship construction. This is one way walls are built in the sustainable earthships around Taos. There are whole communities of these "ships" out past the gorge. Most are bermed with earth on one side and have many windows to capture the solar gain on the south side.Old tires rammed with earth are also used in these unique structures. Most have catchment systems for water and re-use the gray water from the sinks. There is one open to the public if you are visiting in the area and want a first hand tour of these magnificent creations.
