Bioplastics maker Metabolix, Inc. announced that Telles, its joint venture with Archer Daniels Midland Company, has collaborated with Teknor Color Company to develop a range of color concentrates for use with Mirel PHA biopalstic resin. The newly developed color concentrates are formulated using Mirel base resins and meet ASTM D6400 and EN 13432 standards for compostability and biodegradability. The new Mirel colorants are designed to be useful for a wide range of injection molding, sheet, film, and thermoforming applications. Colors are currently being used in the Mirel injection molding grade for laboratory material handling trays, and several colors have been developed for use in consumer retail products.
In addition, a black concentrate is currently being used in the Mirel film grade for agricultural mulch film field trials. Mirel is a family of bioplastic materials with the physical properties of petroleum-based resins, yet with a unique combination of being biobased and biodegradable when disposed in natural soil and water environments, home composting systems, and in industrial composting facilities in areas where such facilities are available. The first commercial-scale plant to produce Mirel bioplastic resins is being constructed adjacent to ADM's wet corn mill in Clinton, Iowa.
