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.
Some of the biggest self-assembled building blocks and structures made from engineered DNA have been developed by researchers at Harvard's Wyss Institute. The largest, a hexagonal prism, is one-tenth the size of an average bacterium.
Arevo Labs' end-production 3D printing technology for carbon composites includes a high-temperature, filament fusion printer head design and firmware for use with the company's new carbon fiber and nanotube reinforced high-temperature matrix polymers like PEEK.
Stratasys will buy Solid Concepts and Harvest Technologies and combine them with its RedEye service business. The plan takes aim at end-production manufacturing and will create one of the biggest commercial 3D printing and AM service bureaus.
The International Federation of Robotics reports that global sales of industrial robots decreased by 4% in 2012 over 2011. The biggest hit was electrical/electronics manufacturing, down by 13%; but by region, the Amerficas did well.
