ECO-FRIENDLY CHEMISTRY2 Eco-Friendly Chemistry Green Chemistry is a term used to describe chemical goods and chemical processes that minimizes or eliminates the production of harmful hazardous material in the environment. Environmental Protection Agency’s (EPA) stride to expand the adoption of this diverse and revolutionary discipline has resulted to great environmental benefits, strengthened economy, and growth of innovation. There are twelve principles that demonstrate the breadth of the concept of green chemistry. Some of the principles are; preventing waste; maximize atom economy, designing safer products and chemicals, use of safer solvent and reaction environment, increased energy use among many others. To support the growth of green chemistry, EPA came up with a presidential Green Chemistry Challenge Award competition that inspires people, organization, and groups to compete for yearly presidential awards that recognizes research in cheaper, cleaner, and smart chemistry. Through honoring and awarding outstanding chemistry projects that incorporates principles of green chemistry into the field of manufacturing, quality control, and design programs key players in the industry will attain pollution prevention goals. This paper presents the 2014 Greener Synthetic pathways Award winners,Cargill, Inc (Anastay, 2002). The recipient demonstrated commitment to designing, implementation and development of green chemical technologies that depicted scientific innovation; it was feasible, economically viable, and less hazardous to both environment and human.
ECO-FRIENDLY CHEMISTRY3 Project Innovation and Benefit Introduction High-Voltage electric transformers were once insulated with fluid to provide cooling and prevent short circuits. The fluid used as insulator wasPolychlorinated biphenyls (PCBs) until the ban was imposed in mid 1970s and scientist adopted mineral oil as its replacement. However, oil was highly flammable and it was toxic to aquatic life such as fish. Cargill finally came up with vegetable oil based transformer fluid that provided superior performance; it was not toxic to aquatic life, less flammable and with lower carbon footprint. The above characteristics make the vegetable oil the best alternative and its effects positive effects to the environment matters a lot. Invention of Vegetable Oil Dielectric Insulating- A Case of Fluid for High-Voltage Transformers For the High-Voltage transformers to work, it must be filled with an insulating fluid which control short-circuiting and absorb extra heat in the experiment.For decades, the transformers were filled polychlorinated biphenyls and the petroleum based mineral oil which was later banned because of the pollution it had on environment. In addition, although the mineral oil was not as hazardous as PCBs, it is very flammable and has negative impacts on aquatic organisms. Moreover, hydrophobic levels of mineral oil is very high and as such, water in the system goes up through the insulating material into the transformer, the uptake rate is increased by the cellulose material that is usually wood. Cellulose materials degrade when they are exposed to water and the standard working temperature of the transformer is altered. In this case, the service life of the transformer was heavily dependent on the shelf life of the solid cellulose insulators
ECO-FRIENDLY CHEMISTRY4 and as such, shielding the degradation process of the insulator was very vital to increase the shelf life of the transformer. Moreover, the vegetable oil takes functions for a longer period and its mechanism is easier and effectively manageable. Due to that challenge, Cargill developed Envirotemp™ FR3™ dielectric fluid from vegetable that was eco-friendly and that was perfectly working for the transformer. The bio based oils was developed to replace the petroleum oil used in transformer because the later was toxic to the environment. The use of the newly developed oil greatly to the transformer, the size of the transformer reduced because of the better thermal performance of the vegetable oil. The FR3™ fluid has been made in such a way that it is not flammable than the normal oil; it therefore minimizes the risk of explosion when temperatures are high. In addition, the Cargill oil increases the shelf life of the cellulose material by 10 times longer than the previously used oil thereby extending the insulation life period and the shelf-life of the transformer. To ascertain the effectiveness of the FR3™ fluid, lifecycle assessment was conducted using BEES® 4.0 and it emerged that the fluid had less carbon footprint in the entire lifecycle of the transformer; moreover, the largest reduction happened in the raw material used, and the transportation phase. After carbon foot print analysis, it was found out that, electric transformer is 60 times more effective when using the vegetable fluid compared to the normal oil. Moreover, the fluid is less toxic, highly biodegradable and the fluid being from vegetable, it is renewable. Finally, there are no single records of explosion and fire for the millions of electric transformers filled with the vegetable fluid since when the FR3™ fluid was launched. The invention of the FR3™ fluid was a great milestone in the power industry because the levels of pollution reduced immensely. In addition, the use of biodegradable material has sparked research and innovation in

ECO-FRIENDLY CHEMISTRY5 the oil industry with scientists adopting more use of eco-friendly materials in their research (Cann, 1999). FR3™ fluid has had a great impact in many industries across the world, it has further improved Environmental Protection Agency Environmental Technology Verification and it has also achieved the lowest environmental impact performance grades in the assessment conducted by BEE experts (Coish, 2016). TheFR3™ fluid has further improved USDA bio-based product clarification with networked research findings that promotes Green Chemistry. Finally, the fluid has been certified by both Underwriters Laboratory and the Mutual Factory research corporation. This development is in FR3™ fluid has had a great milestone in the eco-world. The reduced carbon emission is among the great steps taken to reduce emission of harmful carbon emission in the atmosphere. The use FR3™ fluid is now adopted around the globe by power supplying companies. Environmental Impact of the Green Chemistry Green chemistry has very positive impacts to the environment, first materials degrade to innocuous products or they are recycled for future use, green chemistry further reduces ozone depletion, smog formation, and global warming, moreover, there are less chemicals disrupting the eco-system. Finally, living things that is plants and animals are not affected by toxic chemicals in the environment. Conclusion
ECO-FRIENDLY CHEMISTRY6 Environmental Protection Agency has been giving honors to six winners annually. The awards given are based in six categories namely; academia, green synthetic pathways such the use of biodegradable materials that are eco-friendly, improvement in small business, improvement in catalysts or novel reagent such as microorganism and biocatalysts used in micro-biology, growth of natural processes such as fermentation and the synthesis of biometric, convergent synthesis and the atom economical synthesis. The six categories must be fully supporting Green Chemistry and the use of materials that are not toxic and readily available. Moreover, the honor must adhere to the best designs that adhere to elimination of carbon emission (Singh, 2006). Special honors are given to the projects that reduce the generation of toxic materials such as carbon to the environment, the award has therefore sparked a series of research among scientist more so the young scientist The presidential Green Chemistry has been there for decades, for the last 21 years now; it has had 109 winners in all the named categories. Statistical has proved that, the growth in Green Chemistry has eliminated 826 million pounds of harmful and hazardous toxic chemical materials, it has saved more than 25 billion gallon of water and it has eliminated 8 billion pounds of both carbon monoxide and carbon dioxide emitted to the atmosphere (Hack, 2016). The awards have been a game changer in the scientific world with and the future projections are promising (Clark, 2006). EPA is looking forward to honor more scientists and bring the pollution to its lowest level.
