PETBlock Background Information
The number of people living in areas that can use adobe block construction will increase due to population increases and the expansion of bio-regional areas appropriate for this technology due to man-made climate change. (See Map 1 below) The number of PET (polyethylene terephthalate) plastic bottles available for recycling increased 60% from 2001-2007 and this trend is likely to continue. (See Map 3 below) Coincidentally, the areas most traditionally associated with earthen construction are also areas that often hove significant seismic activity. (See Map 2 below) Combining the anticipated demand for adobe block construction with the availability of surplus recycled materials transformed from PET plastic beverage containers will yield structurally superior and safer construction materials that weigh less and are easier to make than traditional materials. By inventing an inexpensive machine to shred the plastic beverage containers, the possibility of creating a building construction training program becomes possible with micro-financing in developing countries.
