This bicomposite has a PLA base to which coffee waste by-products (coffe grounds) are added. However, these model systems are often very high in purity, making them very expensive to obtain in large amounts. There are a large number of food by-products, such as apple pomaces from apple juice production, carrot pomaces from carrot juice production, or even potato peel or pulp from potato production. This paper aims to review the main case studies related to new circular economy models for waste valorization through extrusion-based additive manufacturing, circular materials, and new design strategies. Essentially, what this means is, that any leftover materials (plastics, woods, etc.) The filament is composed of TPE (thermoplastic elastomer) combined with rubber from recycled tires. Plastic waste is the problem: it takes a very long time to decompose. However, these raw materials are not really utilized as the addition of these ingredients into food products can adversely affect the texture and mouth-feel of foods. On our work floor, we reuse plastic every day to make new products, for example. Responding to the demand for more sustainable and eco-friendly materials, Bausano, an Italy-based manufacturer of custom extrusion lines, is now offering extrusion lines that are specifically configured for processing plastic waste and natural-fibre composites, the company says. This is the challenge we have as the starting point for our research. This filament has a PLA base that is combined with enviromental harmful algae that have been removed from the environment. Global cosmetics firm LOreal, for example, recently committed to using 100% recycled or bio-based plastics in all of its packaging by 2030. Often the waste used is, like PLA, of biological and biodegradable origin, obtaining a final material that is completely biodegradable and bio-based.
