Nature works for Nature Works? PLA

A dozen years ago, scientists at Cargill got the idea of converting lactic acid made from corn into plastic while examining possible new uses for materials produced from corn wet milling processes. In the past, several efforts had been made to develop plastics from lactic acid, but with limited success. Achieving this technological breakthrough didn’t come easily, but in time the efforts did succeed. A fermentation and distillation process using com was designed to create a polymer suitable for a broad variety of applications.

As an agricultural based firm, Cargill had taken this product as far as it could by 1997. The company needed a partner with access to plastics markets and polymerization capabilities, and began discussions with The Dow Chemical Company. The next step was the formation of the joint venture that created Cargill Dow LLC. Cargill Dow’s product is the world’s first commercially available plastic made from annually renewable resources such as com:Nature Works? PLA is a family of packaging polymers (carbon-based molecules) made from non-petroleum based resources.Ingeo is a family of polymers for fibers made in a similar manner.

By applying their unique technology to the processing of natural plant sugars, Cargill Dow has created a more environmentally friendly material that reaches the consumer in clothes, cups, packaging and other products. While Cargill Dow is a stand-alone business, it continues to leverage the agricultural processing, manufacturing and polymer expertise of the two parent companies in order to bring the best possible products to market.

The basic raw materials for PLA are carbon dioxide and water. Growing plants, like com take these building blocks from the atmosphere and the soil. They are combined in the plant to make carbohydrates (sucrose and starch) through a process driven by photosynthesis. The process for making Nature Works PLA begins when a renewable resource such as corn is milled, separating starch from the raw material. Unrefined dextrose, in turn, is processed from the starch.

Cargill Dow turns the unrefined dextrose into lactic acid using a fermentation process similar to that used by beer and wine producers. This is the same lactic acid that is used as a food additive and is found in muscle tissue in the human body. Through a special condensation process, a lactide is formed. This lactide is purified through vacuum distillation and becomes a polymer (the base for NatureWorks PLA) that is ready for use through a solvent-free melt process. Development of this new technology allows the company to “harvest” the carbon that living plants remove from the air through photosynthesis. Carbon is stored in plant starches, which can be broken down into natural plant sugars. The carbon and other elements in these natural sugars are then used to make NatureWorks PLA.

Nature Works PLA fits all disposal systems and is fully compostable in commercial composting facilities. With the proper infrastructure, products made from this polymer can be recycled back to a monomer and re-used as a polymer. Thus, at the end of its life cycle, a product made from Nature Works PLA can be broken down into its simplest parts so that no sign of it remains.

PLA is now actively competing with traditional materials in packaging and fiber applications throughout the world; based on the technology’s success and promise, Cargill Dow is quickly becoming a premier player in the polymers market. This new polymer now competes head-on with petroleum-based materials like polyester. A wide range of products that vary in molecular weight and crystallinity can be produced, and the blend of physical properties of PLA makes it suited for a broad range of fiber and packaging applications. Fiber and non-woven applications include clothing, fiberfill, blankets and wipes. Packaging applications include packaging films and food and beverage containers.

As Nature Works PLA polymers are more oil- and grease-resistant and provide a better flavor and aroma barrier than existing petroleum-based polymers, grocery retailers are increasingly using this packaging for their fresh foods. As companies begin to explore this family of polymers, more potential applications are being identified. For example, PLA possess two properties that are particularly useful for drape fabrics and window furnishings. Their resistance to ultraviolet light is particularly appealing as this reduces the amount of fading in such fabrics, and their refractive index is low, which means fabrics constructed from these polymers can be made with deep colors without requiring large amounts of dye. In addition, sportswear makers have been drawn to the product as it has an inherent ability to take moisture away from the skin and when blended with cotton and wool, the result is garments that are lighter and better at absorbing moisture.

PLA combines inexpensive large-scale fermentation with chemical processing to produce a value-added polymer product that improves the environment as well. The source material for PLA is a natural sugar found in plants such as com and using such renewable feedstock presents several environmental benefits. As an alternative to traditional petroleum-based polymers, the production of PLA uses 20%-50% less fossil fuel and releases a lower amount of greenhouse gasses than comparable petroleumbased plastic; carbon dioxide in the atmosphere is removed when the feedstock is grown and is returned to the earth when the polymer is degraded. Because the company is using raw materials that can be regenerated year after year, it is both cost competitive and environmentally responsible.

Some people believe the purpose of education is to prepare people to be useful members for society. Others say that the purpose of education is to achieve personal ambitions. Discuss both views and give your own opinion.

大作文7分范文

Nowadays, it is stated that the aim of education is to cultivate valuable talents to the society, while others deem that it is the reason of pursuit of personal achievements that we get educated. This essay will discuss both sides of the view, followed by my own perspective on this matter.

People who consider the purpose of education as training useful workers may propose following reasons. To begin with, exposing students to a wide range of subjects can equip them with necessary knowledge and skills which can be applied to the practice after graduation. For example, the grasp of in-depth knowledge in medical area can help medical graduates in universities treat patients in their future career, which guarantees the social healthcare system to operate continuously. In addition, the learning of social moral values in schools can also help young people build up correct beliefs, thereby preventing them from committing crimes. Specifically, it is the compulsory course of moral values in China that has reduced the crime rate in the society in recent years.

However, those who believe education helps young generation achieve their goals also have reasonable arguments. For one thing, compared with students who drop off early in school, those who have higher education qualifications are more likely to be employed in their preferred companies and engage in the work they are passionate about. For another, it is the skills such as leadership and teamwork besides theoretical knowledge that allows new employees to be skillful and adaptable to the workplace, enabling them to realize their ambitions.

As discussed above, I believe that the education plays an inevitable role in one’s life and it has multiple functions. Therefore, it is convinced that the purposes of education include both cultivating intellectuals and being a foundation to those who intend to achieve their individual values.
