Plastics are inexpensive, easy to produce and present a large variety of properties. That is why we use them for plenty of different applications, from house appliances or lunchboxes to cars’ components and disposable carrier bags. However, the current concern for the environment has pushed us to reduce their use. But is this possible? We are currently producing 250 million metric tonnes of plastic per year worldwide and it is expected to keep increasing in the next years. Bioplastics are presented as the miracle sustainable alternative to traditional plastic, covering the societal needs while saving the environment. How good are they? In this presentation, I will briefly talk about the history of plastics, how they are made and the real sustainable alternatives.
