Dinoyar wants to know What are the developments in the field of conventional and bio degradable plastics after 1980? 9 months ago
From the data that I have been through new plastics have been discovered till 1980 after that applications were looked into.
Please correct me if I am wrong.Thank you.-
Hi! Thought I would provide some inputs on what's the latest in biodegradable plastics: 1. Rapidly-Biodegradable Hydrophobic Material - RBHM (New Approach to Biodegradable Products) - "We have patented and developed cellulose-based rapid biodegradable hydrophobic material (RBHM). RBHM is a new, hydrophobic, strong, cheap recyclable, repulpable and completely biodegradable composite material of newly type that is environmentally friendly. RBHM has shown great promise in improving the properties of both paper and plastics packaging aterials. Due to its recycle and biodegradable nature, Rapid Biodegradable Hydrophobic Material is ideal to be applied for the disposable grocery bags and packages. The material can be used as a commodity in trade, industry and agriculture for a wide range of applications. Today, most attempts to produce biodegradable products for consumers focused on developing plastics that could biodegrade. RBHM approaches biodegradable products from the other direction: making cellulose-based material with the same physical properties as plastic, except the material is recyclable and completely biodegradable in the same time as regular paper bags. RBHM consists of cellulose (paper) and biodegradable organic additives." - http://figovsky.borfig.com/genius.aspx 2. Biodegradable Plastic Made From Wood By-product - "Ground-Breaking Invention May Replace Conventional Plastic- Arboform, an innovative liquid wood material invented by a German scientist, may completely eliminate the need for energy-intensive plastic products in the future. The ground-breaking invention uses an otherwise useless element of actual wood, lignin, which is then combined with natural resins, flax and fibers. The end product can be infused into molds to form intricate, precision-shaped objects usually made with environmentally hazardous petroleum-based plastics" - http://www.renewable-energy-news.info/biodegradable-plastic-made-from-wood/ 3. Improving Biodegradable Plastics Manufactured from Corn - Biodegradable plastics made from polylactic-acid-based polymers (PLA) derived from plants could provide the solution. In manufacturing, PLAs consume much less energy than plastics using petroleum-based feedstocks, and they decompose much faster than do petroleum-based plastics. However, PLA products lacked resistance to higher temperatures; for example, a hot-beverage drinking cup would distort when filled with a hot liquid. In addition, PLA plastic parts were expensive to manufacture, partly due to the additives necessary to improve the hardening time and other properties of the plastic resin used to make the products. Cargill, Inc. was an agriculture company that had been researching plant-derived plastics. They proposed to improve plastics made of corn-based PLA by making them easier to manufacture and more heat resistant. Their comprehensive research approach required advances in polymer blends, additives, and manufacturing techniques and involved high technical risk, so the company needed outside funding. In 1994, Cargill applied for and received Advanced Technology Program (ATP) funding for a three-year project that started in 1995. With ATP funding, Cargill reduced the hardening time for products made from PLA. Dow Chemical provided expertise in plastics manufacturing - http://statusreports.atp.nist.gov/reports/94-01-0173.htm 4. Novel Feedstock for Biodegradable Plastic - An unusual polysaccharide has been identified that can be extruded as a biodegradable plastic. Unique properties allow it to replace certain petroleum-based plastics at the same price as other bioplastics. To gain quick acceptance, details of the process developed during the Phase I project will be published. Revenues will be obtained from sales of the polysaccharide. As the volume of polysaccharide sales increases, the price will further decrease. Plastic manufacturers will not need to change equipment; the change will be in the raw materials. Environmental regulations, problems with plastic disposal, and increases in the price of oil are concerns for the $375 billion plastics industry. For many, production of a “green” plastic would provide a competitive edge and open new markets. Preliminary work has shown that it is possible to extrude this polymer into a plastic that will dissolve in water in less than 12 hours. An innovative formulation will make a second product resistant to water for 12 hours but still soluble in less than 1 week. The solubilized plastic is degraded easily into sugar monomers, which can be used as an energy source by numerous microorganisms. Derived from an agricultural product and safe for both users and the environment, this polysaccharide reduces pollution throughout its life cycle. - http://cfpub.epa.gov/ncer_abstracts/index.cfm/fuseaction/display.abstractDetail/abstract/7952/report/0

Gaya3 shared a video Producing Bioplastics from Whey Protein 8 months ago
Cheese factories in European Union generate nearly 50 million tonnes of whey as a by product in the cheese factories, of which a majority is used as a supplement by body builders.
While rest of the whey is discarded as a waste.
The whey is spray dried to obtain the whey protein in a pure form and which following this it is processed to convert it into a thin film of plastic. -
Bioplastics can take different length of times to totally compost, based on the material and are meant to be composted in a commercial composting facility, where higher composting temperatures can be reached and is between 90-180 days. Most existing international standards require biodegradation of 60% within 180 days along with certain other criteria for the resin or product to be called compostable. It is important to make the distinction between degradable, biodegradable and compostable. These terms are often (incorrectly) used interchangeably.
Compostable Plastic is plastic which is "capable of undergoing biological decomposition in a compost site as part of an available program, such that… -
