environmental and economic disaster. The main problem with landfills is that they are complicated structures that are difficult to maintain. Of particular concern is the wastewater created inside landfills as leachate. In order to keep the toxic material from leaking into the local drinking water, these football stadium-sized holes require a combination of liners made from clay, high-density polyethylene (HDPE) plastic or composite membranes. But according to the Environmental Research Foundation

Modern cars are made from a variety of materials. The materials chosen depend a lot on their cost, repairability, and durability. Fuel efficiency is just one of many variables on the minds of car designers. The typical family sedan these days is usually made from steel body panels with plastic front and rear fascias. Some of them may have an aluminum hood and rear deck lid for weight savings. The unibody (the underlying frame) is almost always made from a combination of steel and special (and
