Candy wrappers and plastic bottles turn out to be incredibly versatile materials when recycled. Now, Argentina's Experimental Center for Economical Housing (Centro Experimental de la Vivienda Económica - CEVE) is using these materials as the basis for building bricks. According to The Temas Blog, the bricks are light, durable, and inexpensive.Additionally, the organization has also created a roofing material that combines plastic bottles with crushed peanut shells and/or wood shavings. Funded in part by Germany's technical cooperation agency GTZ, CEVE gathers materials for the bricks from a municipal recycling plant, school and government collection centers, and a bottling plant that donates its rejects.
