This bottle is familiar to everyone. It is made from PET. Many companies are searching for a way to replace it with a bioplastic. This is already available in the form of PEF. PEF is made from sugar, is 100% bio-based and recyclable, and can be used to create food packaging with even better properties. However, PEF is expensive to produce, particularly due to one raw material: FDCA, which is difficult to manufacture using chemical processes. At Tasseikan, we have developed an alternative: the biotechnological route. We use microorganisms to convert sugars into FDCA. If you use sugars as your starting point, they can come from an important source: the most efficient solar collectors we know — plants and trees. These are perfectly capable of producing sugars using sunlight and CO2. In fact, they produce enough to feed and provide materials for everyone in the world. Combining these advantages, we can produce FDCA at low cost using a simple process. This enables us to introduce PEF as a bio-based plastic, offering a useful alternative to PET bottles.
