One single-use plastic bag takes at least 450 years to degrade. Give Miranda Wang three hours and she can reduce ten of them into liquid. Recycling plastic today is a mechanical process ... limited to only certain types of plastics: PET, used in water bottles, and HDPE, used in milk jugs. The five other types of commonly used plastics ... cannot be recycled. Adding to this is that most plastics thrown away are covered in food and grease and so are automatically rejected by markets with strict quality standards. These are the plastics Wang has her sights on. Our technology can turn these dirty films that have food or dirt or any kind of grime or any kind of contamination on it and we turn this material into a combination of four different kinds of chemicals, called organic acids," says Wang. One of these chemicals is adipic acid, a precursor for materials like nylon and polyamines used in fashion, for electronic parts and in the automotive industry for car parts. "Our vision is to transform a polyethylene, which right now does not have any downstream market value once its consumed and is used for one life cycle, and we turn it into a chemical that is of the same quality as what is immediately made from petroleum - adipic acid," says Wang. "This first helps us not allow film plastics from becoming pollution and second ... displaces petroleum from being needed to be extracted to make new materials."

Each news summary is created according to strict standards. Here's how we do it.
Each summary is created using a consistent editorial procedure. The target length is approximately 16 lines of 11-point Arial text in a 650-pixel-wide column. Up to 25% of a summary may be set in bold to emphasize the most important ideas. Summaries are composed of verbatim excerpts presented in the same sequence as they appear in the original news source, with very minor editorial additions. Where material has been omitted between excerpts, the omission is indicated with ellipses (...). Any words added by an editor for clarity or context appear in [brackets]. Our original news editor was Fred Burks. Tod Fletcher edited most summaries from 2007 through 2014, and Mark Bailey has served as news editor since 2014.
