Presentation on Bioplastics :: Environment polypropylene renewable resources
Presentation on Bio plastics Bioplastics, What ar they? * Compostable Plastics -or- * Any plastics-made from organisms (or Organism by-products). * menstruationly, there is much confusion over the translation of bioplastics Mixture of Acids that could be made into bioplastics Making Bioplastics, Etc. Goal of Bioplastic product * To Save Resources by either reducing the production of standard polypropene plastics by replacing it with a less resource-intensive plastic. * Or Save the environment by making plastics biodegradable * Or, both Bioplastic degradation speed What are Scientists Doing Now? Several Different Exciting Methods are cosmos tested right now * Using soya-based bioplastics * Using Bacteria to make bioplastics * Starch-based Bioplastics * Polylactide Bioplastics * Poly-3-Hydroxybutyrate Current Cost of Bioplastic Comparison Soy-based Bioplastics One of the hottest sections in bioplastics research today.Pure Soy Bioplastic has many undesirable traits.Mixtures of Soy with other substances are currently being attempted.The Soy shown Soy Protein Bacteria-based Bioplastics Steven Pratt of New Zealand (Major New Discovery)Mixture of bacteria bath create acids when fermented.The ratio of antithetic acids is based on pH.The bacteria are fed glucose solution and fermented.The acids can be utilize to make bioplastics Starch-Based * beat up about 50% of the current bioplastic market * Are used in pills that you take * Can be specificially tailored by adding different amounts of plasticizers * This is called thermo-plastical starch Polylactide Bioplastics * Lactic acid is turned into Polylactide by adding a atom smasher and heat. * Polylactide bioplastics can be made on existing petroleum plastic equipment * Resembles plastic in propertiesPoly-3-Hydroxybutyrate * A polyester * Easily biodegradable * Easily process * Currently very expensive * Curre nt interest is very naughty * Methylobacterium sp V49 is one bacteria that produces Poly-3-HydroxybutyrateChallenges Facing Bioplastics * Economically Unfeasible * Biodegradability is a reusable and a not-so-useful property
