The Coca-Cola Co. is making impressive environmental improvements in its bottles. As reported here, Coke is the first company to introduce a beverage bottle made with recycled plastic. Earlier this year, Coca-Cola opened the world’s largest plastic bottle-to-bottle recycling plant in Spartanburg, SC. Now Coke has announced the “PlantBottle”, which is made from a blend of petroleum-based materials and up to 30 percent plant-based materials. The feedstock, presumably ethylene glycol via glucose, is made from sugar cane and molasses, a by-product of sugar production. Coca-Cola said it is also exploring the use of other plant materials for future generations of the bottle. A life-cycle analysis conducted by Imperial College London indicates the “PlantBottle” with 30 percent plant-base material reduces carbon emissions by up to 25 percent, compared with petroleum-based PET.
Another advantage to the “PlantBottle” is that, unlike other plant-based plastics, it can be processed through existing manufacturing and recycling facilities without contaminating traditional PET. Coca-Cola North America will pilot the “PlantBottle” with Dasani and sparkling brands in select markets later this year and with vitaminwater in 2010
“The ‘PlantBottle’ represents the next step in evolving our system toward the bottle of the future,” said Scott Vitters, director of Sustainable Packaging of Coca-Cola. “This innovation is a real win because it moves us closer to our vision of zero waste with a material that lessens our carbon footprint and is also recyclable.”
A recent report sponsored by the American Chemistry Council (ACC) focuses on emerging gasification technologies for converting waste into energy and fuel on a large scale and saving it from the landfill. Some of that waste includes non-recycled plastic.
Capping a 30-year quest, GE Aviation has broken ground on the first high-volume factory for producing commercial jet engine components from ceramic matrix composites. The plant will produce high-pressure turbine shrouds for the LEAP Turbofan engine.
Seismic shifts in 3D printing materials include an optimization method that reduces the material needed to print an object by 85 percent, research designed to create new, stronger materials, and a new ASTM standard for their mechanical properties.
A recent study finds that 3D printing is both cheaper and greener than traditional factory-based mass manufacturing and distribution. At least, it's true for making consumer plastic products on open-source, low-cost RepRap printers.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
