The backpack demonstrates in an exemplary form how variable the materiality of the bioplastic can be in a variety of applications and what functions it can assume. This is because everything from the textile to the zipper and the paddings is made from only one material. Necessary properties of the backpack, such as stability, flexibility and wearing comfort, are realized by shaping the PHB in a specific form using polymorphic structures.<br>Even though PHB is still too expensive for mass production today, it will be possible to manufacture a wide range of everyday products from PHB in the future. For example, although the synthesis of the plastic by bacteria is quite expensive, it does neither require fossil resources, nor does the production compete with the food industry. A future-oriented way to produce PHB could be the synthesis of PHB in symbiosis of cyanobacteria and PHB-producing bacteria. Using carbon dioxide and sunlight, the cyanobacteria are able to generate polysaccharose, which provides a food source for the PHB-producing bacterium. The extracted PHB could be cast into films or further processed into various products using conventional plastic processing machines.<br><br>In the future, products made from pure PHB will be labelled with a new recycling symbol so that consumers can easily identify the bioplastic and return their PHB waste to a local Aggregat-Store for a small deposit.<br><br>The Aggregat-Store uses the collected waste PHB to make new products. Some of the material is cleaned, shredded, sorted by colour and extruded into 3D printing filament. Film-based products such as rain capes, tarpaulins, etc. are scanned for utility using an innovative technology and then punched into plug-in modules.<\/p>\n\n\n\n<p class=\"subtitle\"><br><\/p>\n\n\n\n<p class=\"subtitle\"><br><br><\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:33.34%\">\n<p class=\"subtitle\">The aggregate backpack is completely modular. All components are connected and disconnected by plugging, clipping or screwing mechanisms, based on a flexible textile made from a large number of small basic modules. Without sewing or gluing, three-dimensional shapes can also be plugged in.<br><br>Additional functions such as hooks and clips, zippers or pockets on the inside or outside are simply added with the help of special modules.<br><br>In addition, based on the original design, the shape, size and colour of the backpack can be customized to match the individual needs of the user. By using recycled material, the aesthetics of the Aggregat is significantly determined by this material.<br><br>The customer can assemble the backpack according to his or her own wishes online or directly at the store. The Aggregat-Store also offers a DIY corner, where customers can use their own materials to create their own personalized pieces.<br><br>And if a backpack ever breaks, the store offers a free repair service. Broken modules are simply exchanged for new, suitable ones. Thanks to this easy reparability, the product is kept in a long-life cycle.<br><br>If a module has become unusable, it is melted down and processed into filament or new films and mechanically recycled.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:33.33%\"><\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n<div style=\"height:62px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>AGGREGAT Polymorphism in a backpack The backpack Aggregat is an example for the variable application possibilities of the bioplastic PHB.
