4 Blue Waves cups use up to 50% less plastic than traditional coating.
During the pulping process, paper pulp fibers are separated from the plastic coating along with any food and dirt particles. The fibers float to the top of the pulper, leaving the particles to sink to the bottom where they are captured as waste. Unfortunately, traditional paper cups are made with a plastic coating that floats to the top of the pulper along with the fibers, causing problems. These light plastic flakes clog the recycling screens and prove too difficult for recyclers to process through their equipment. As a result, traditional paper cups are not accepted by recyclers and over 50 billion of them are sent to U.S. landfills each year.
4 Blue Waves uses EarthCoating® which is a mineralized resin. It fractures into small, dense particles which sink in the pulper, leaving the fibers to easily move forward in the process. If any of these particles get trapped in the fibers as they float to the top of the pulper, they are small enough to pass through the recycling screens without any problems. If the particles enter the secondary and fine cleaners, they are captured there, leaving the fibers to enter the paper making phase of the process.
