tics to the conventional crystalline or semi-crystal- line forms. The company says interest in aPHA as a performance boosting component in bioplastic compounds has increased over the past year in a wide range of end markets, including cosmetic packaging, food packaging and organic waste management. The company says in the food packaging market


in particular, brands are responding to consumer demand for products with more bio-based content and end-of-life options such as composting. It says aPHA provides a practical solution as it is TUV OK-certified for industrial and home composting and is both soil and marine biodegradable. Recent tests have shown that blends of PLA and aPHA can be made home compostable (pure PLA can only be composted in industrial plant) if the aPHA/PLA ratio is greater than about 0.5. The company says this is significant as it extends the range of applica- tions for PLA/aPHA blends to areas such as flexible packaging. “The use of aPHA has increased over the past


year as more organisations have started working proactively to replace plastic with more sustainable solutions, but we expect the speed of adoption to

continue to accelerate. Right now, there is a lack of understanding about the value and unique advantages of aPHA. It’s similar to the 1950s when polyethylene was introduced. The market had to figure out what the new material was and how to use it effectively before they could start working with it,” says Raj Krishnaswamy, VP, Research & Development at CJ Biomaterials. He cites the example of cosmetic packaging developed for CJ Olive Young, which is a leading
