The World of Bioplastics Created by Ecker Josef, Bsc Target Audience: University Students

Why Bioplastic? -5,800,000 m² -twice the size of the continental United States - swallowed 59 different plastic items - totaling over 17 kg - equal to 900 PET- Bottles Solution? [1,2]

Why Bioplastic? plastics made from crude oil when plastics made from petroleum are burned, they release the carbon dioxide renewable resources are becoming a alternative for the plastics industry The use of bioplastics offers significant advantages [3]

“ Biodegradable plastics are plastics that are capable of being decomposed by bacteria or other living organisms” „ Renewable plastics are raw materials derived from renewable biomass ressources“ What are Bioplastics?

Biodegradable Renewable What are Bioplastics? [4]

What are Bioplastics? [5]

State of the art – Starch-based-plastics energy-efficient and economic plastic parts production defies an additional biotechnical synthesis stock of starch is almost inexhaustible can be extracted from potatoes, maize, corn or cassava [6,7]

Locations of starch source: State of the art – Starch-based-plastics [18]

the plastics PLA and PP containing starch increase: o rigidity o strength o stiffness o heat-resistance o printability needs to be dried before processing! State of the art – Starch-based-plastics [18]

highly functional polymeric natural material offer almost infinite possibilities in material properties usually produced from wood pulp production defies an additional biotechnical synthesis State of the art – Starch-based-plastics [7,8]

Applications Disposable items such as packaging and catering items used for bags, trays, containers for fruit, vegetables, eggs and meat, bottles for soft drinks and dairy products, and blister foils for fruit and vegetables. [9,10]

Applications Nondisposable applications include mobile phone casings, carpet fibres, and car interiors, plastic feeding syringe and plastic pipe applications, new electroactive bioplastics [11,12]

Applications Nondisposable applications Location: Stuttgart Name: AbroSkin facade of 90% renewable Bioplastic Manufacturing: Extrusion -> Thermoforming [13]

Applications Medical implants made of PLA, which dissolve in the body, save patients a second operation. Compostable mulch films for agriculture, already often produced from starch polymers, do not have to be collected after use and can be left on the fields. [14]

Summary Starch and cellulose can be mixed with plastic to allow it to degrade more easily Starch and cellulose have proven too costly and limited for general use on landfills, they can become "mummified" and persist for decades even if they are supposed to be biodegradable. [5,15]

Future completely biodegradable plastics  BASF Ecoflex  Carbon that is locked up in them is released into the atmosphere as the greenhouse gas carbon dioxide!! [16,17]
