There have been major moves under way to improve bottle design. Triggered by huge price hikes for plastics last year, the first trend features thin-walling, which is also a green improvement. A process refinement enabled a 19 percent weight reduction, saving over three million pounds of plastic annually in a Kraft salad dressing bottle. The optimized bottle design increased shipping efficiencies by 18 percent by allowing a greater number of bottles shipped per truckload. There has been an explosion in bottle thin walling in the past 18 months.
There has also been a huge improvement in the use of recycled PET in bottles. One of the leaders is Coca-Cola, which is developing a joint venture plant in South Carolina to produce food-grade recyclate. Capacity of the plant will be one billion pounds/yr, with half of the capacity being used by Coke and other half sold to external blow molders. Virtually all of the raw materials will be coming from municipal recycling programs. Coca-Cola Co. said it will boost recycled content of its PET bottles to 10 percent by the end of 2010 and 25 percent by 2015. Coke had reached 10 percent recycled content in North America in 2004 and 2005, but the level slipped to 3 percent or less. Coke’s wants to keep recycled material cost neutral with virgin PET. There is so much demand now for recycled PET that there actually is a shortage of supply.

A Columbia University team working on molecular-scale nano-robots with moving parts has run into wear-and-tear issues. They've become the first team to observe in detail and quantify this process, and are devising coping strategies by observing how living cells prevent aging.
Many of the new materials on display at MD&M West were developed to be strong, tough replacements for metal parts in different kinds of medical equipment: IV poles, connectors for medical devices, medical device trays, and torque-applying instruments for orthopedic surgery. Others are made for close contact with patients.
