When it comes to 3D printing, the sky is the limit. As 3D printing technology continues to advance, applications can be as far reaching as airplane and automobile parts to medical devices and even anatomically correct, biocompatible models. Although 3D printing technology is developing at a rapid pace, the technology itself is not new. It emerged in the 1980s as a means of creating rapid prototypes. In recent years the applications for 3D printed models have evolved with the available hardware, software, and printable materials. Evolving technology, paired with the creative and innovative minds of scientists, engineers, and physicians, has been the launching pad for developments within 3D printing technology specific to healthcare. One way 3D printing technology is poised to create better patient outcomes is in creating an anatomically and patient-specific models to aid in surgery and medical procedures. With the capability to 3D ...
Coca-Cola and PepsiCo are trying to make plastic soda bottles out of 100% plant-based materials. Last week, media outlets reported that both companies gave updates on their progress.
Coca-Cola announced that it plans to work with three biotech companies and could have all-plant bottles out to consumers in a few years. PepsiCo, which said in March that it had developed an all-plant bottle, announced last week that the company was on schedule for a production test-run of 200,000 of those bottles.
“Coke was the first out of the gate in the green bottle race, when in 2009 it began selling Dasani water in the United States in bottles made with up to 30 percent plant-based plastics,” and last week, the company added that all of its bottles would meet that standard by 2020, writes William Neuman for The New York Times. (Coke’s Odwalla juice brand is sold in all-plant bottles appropriate for juice.)
Setting a target date for producing Coke’s all-plant bottles is trickier. According to the Associated Press:
‘While the technology to make bio-based materials in a lab has been available for years, we believe Virent, Gevo and Avantium are companies that possess technologies that have high potential for creating them on a global commercial scale within the next few years,’ said Rick Frazier, vice president of commercial product supply for [Coca-Cola].
Denise H. Lefebvre, PepsiCo’s vice president for global beverage packaging, told The New York Times that Pepsi was also “teaming up with companies that are developing different ways of solving the plastic puzzle.” She declined, however, “to identify the partners.”
Pepsi is also hesitant to set a date for large-scale production of all plant bottles. Lefebvre added to Neuman that if the test doesn’t prove that the new technologies are cost-effective on a commercial scale, more experimentation will be needed.
Neuman writes:
Soda bottles are made from a type of plastic known as PET, which commonly has two main components. One, called MEG, makes up about 30 percent of a bottle’s weight, and is what Coke has been producing from plant sources, using sugarcane grown in Brazil.The other component, called PTA, makes up 70 percent of a bottle’s weight. Scientists have been able to make PTA from plant materials in the laboratory but pulling off the same trick on an industrial scale has proved more difficult.
Neuman reports that Pepsi has said it will use agricultural waste products, such as corn husks, pine bark, or orange peels to make its plastic bottles and that Coke’s perspective materials include wastes and crops grown for plastic production.
