Banned Box The foam "clambox" is dead -- long live recyclable paper! Environmentalists urged restaurants to stop using polystyrene-foam packaging, calling the product a toxic hazard and a landfill-clogging waste. In 1990 someone listened: McDonald's promised to phase out its familiar hamburger containers...
Oxidized LDL could be lethal in another manneras well: by attracting "foam cells" ormacrophages, which cause plaque to grow on arterywalls, the molecule may lead directly to heartdisease...
...materials are usually designed on computers, which can analyze exactly how the molecules of different substances will fit together. As a result, complex compounds can be made to order for specific tasks. They can be engineered to be as solid as cement yet as light as foam cushion, or sturdy like steel but pliable like rubber. Because of their superior properties, advanced materials are rapidly replacing ordinary steel, aluminum and plastics in everything from cutlery to cars. Scientists have high hopes of conserving natural commodities such as iron, wood and rubber. Says Robert Newnham, a professor of solid-state science...
McDonald's will probably replace its foam hamburger boxes with material similar to the thin paper used to wrap its smallest sandwiches. That is not a perfect solution either. The paper is not yet recyclable, and while it does break down in landfills, its production requires cutting down trees. But it takes up 90% less space than foam when discarded, and McDonald's is testing a paper-recycling technique in some of its California stores. If it can find alternatives, the chain may also replace its polystyrene plates and coffee cups...
...possible substitute for some uses of polystyrene comes straight from nature. To replace the plastic-foam pellets that are used to protect delicate merchandise during shipping, at least two companies in California are trying to market a biodegradable, in fact edible, alternative: popcorn. The drawbacks are that it is more expensive to produce than polystyrene pellets and tends to ) attract rodents and insects. Nonetheless, a handful of mail-order companies and other shippers in the U.S., Canada and Europe have begun packing with popcorn (butter and salt not included). Such small innovations, along with dramatic shifts by companies like McDonald...
