Greenchemistry is an exciting field of chemical applications upon whichthe chemists aim to develop compounds that have lowered hazardousemissions. The green chemistry not only touches on the manufacture ofthe chemical components, but it extends to cover the design,manufacture, and usage of the substances. Additionally, the greenchemistry involves learning of the correct means to dispose of thechemical products. Many might confuse the processes of greenchemistry with the proper cleaning up pollution. However, the methodsof green chemistry entail reducing the chances of contaminationoccurrence at the origin of the chemical components. It is correct tosay that the remediation activities carried out in cleaning pollutiondo not necessarily touch on green chemistry. The restorationprocesses in the pollution clean-up remove the hazardous materialsexisting in the environment, while the aims toeliminate and reduce the hazardous materials from ever getting to theenvironment. The following write-up explains the major components inthe green chemistry application.
Greenand sustainable chemistry is an alternative way to which there is adifferent method of producing chemicals and varied processes ofcarrying out chemical engineering. The alternative and diversemethods drive the scientists to come up with better plans to producechemicals, which can protect and benefit the economies, the people,and more so the environment (Boodhoo 2012). The methods additionallyaim to reduce the waste disposed to the environment, bring alongconservation of energy, and direct innovation for replacements to thecurrent hazardous chemicals (Boodhoo 2012). The production andutilization of green chemistry attempt to help the producers todevelop compounds that offer lowered environmental pollution.Lowering the environmental pollution begins by reducing the amount ofhazardous components in the chemicals that eventually harms theenvirons.
Amongthe leading applications of green chemistry in the various chemicalproductions are through source reduction. Source reduction is amethod of production of chemicals where the design, manufacture, andpackaging of the chemical components limits the levels of toxicity ofthe waste of the components (Dicks 2014). Hence, the source reductionreduces the overall amount of the waste that gets into theenvironment. Applying source reduction when producing the chemicalcompounds for the various applications creates the need to lower theamount of raw materials that make up the chemical components.Reducing the raw materials for the chemical components lowers thehazardous materials that will end up in as waste after utilization ofthe chemical compound. Various principles apply directly to theapplication of green chemistry in the production of chemicalcompounds. They range from basic applications such as using safersolvents and reactions, coming up with artificial processes that areless hazardous, minimizing any production of products that emitmassive amounts of waste lowering potential risks for accidents, anddesigning chemicals and products that are safer than the current onesused in the manufacturing processes (Dicks 2014).
Moreprinciples in the green chemistry application in industries involveutilizing renewable feedstocks to lower the potential risk ofdepleting the raw materials and scrutinizing chemical processinginstantaneously to limit pollution. Running reactions at the roomtemperature will increase the efficiency of the compounds hence,lowering the hazardous wastes (Sharma 2010). More so, the greenchemistry principles dictate designing chemicals and compounds thatdisintegrate after use (Sharma 2010). Besides, the principles extendto the use of catalysts to replace the stoichiometric reagents,maximizing on the atom economy, and limiting the usage of chemicalderivatives.
Inthe applications of green chemistry, using of catalysts has betterpreference over the stoichiometric reagents. The preference for thecatalysts is because they can be used in small quantities and morethan one applications unlike in the stoichiometric reagents, whichcan only be used once and in high amounts. Hence, by using thecatalysts, there is a reduction in the overall hazardous waste. Byavoiding the use of chemical derivatives, the production processeslower the overall waste amounts since the derivatives need additionalreagents to achieve optimum results (In Peterson 2015). Adding thesupplementary reagents adds to the level of hazardous waste from thefinal chemical compound. Through the processes of maximizing atomeconomy, the production is such that it utilizes the maximum amountof the available raw materials to come up with the final chemicalproduct (In Peterson 2015). Consequently, there are less wasted atomsfrom the production process.
Theapplication of green chemistry follows a hierarchy to produce thechemical products with no risk of degrading the environment. Thesource reduction and the prevention of the chemical hazards producechemicals that are less hazardous to the environment and the humanlife. More so, they design syntheses with very low or no chemicalwastes, and that use very low water and energy in their usage.Additionally, the processes come up with chemical products that arere-usable and recyclable. Furthermore, before releasing the chemicalcomponents to the end-users, source reduction methods may treat thechemicals to extract the toxicity before the disposal time. The greenchemistry may sometimes allow for the disposal of the untreatedchemicals safely only when the other options of handling theuntreated waste exceed feasibility expectations.
Greenchemistry also defines the chemicals that are not hazardous to thehuman beings and the environment as being less toxic to any livingorganisms. The chemicals are also less destructive to the naturalecosystems. Moreover, the less hazardous chemical products are notbio-accumulative or persistent in any organisms in the environment.In addition, the less dangerous chemical products are safer to handlethan the harmful components since the recent lack any explosive orflammable characteristics that pose a risk to the end-user.
Greenchemistry has a lot of benefits to the industrial applications andthe environment. It helps chemicals degrade at a faster rate, lowersthe toxicity of the chemicals released, decreases the potentialdepletion of the ozone layer, there is a low requirement of landfillsneeded to bury the hazardous chemical components, and keeps livingorganisms safe. Green chemistry provides increased occupationalhealth and safety of workers working in the chemical industries. Theless pollution from the green chemistry means there are cleaner airand water hence, the human health benefits. The lessened pollutionleads to the production of healthy foods eliminating the risk posedby chemically engineered foods. Green chemistry elevates theenvironmental protection mandate higher by the creation of a newreality that asks the chemical engineers to design, manufacture, andpackage the chemical products in a way that eliminates the toxicityposed by the chemical products.
Ithink the processes of green chemistry are imperative to preventingthe world from succumbing to the dangers of environmentaldegradation. More so, the destruction of the environment by theperilous chemicals will undermine the sustainability levels of naturefor the future generations. The incorporation and adoption of greenchemistry in the design, manufacture, and package of hazardouschemicals will offer a massive reduction in the levels of pollutionto the environment. Various industrial activities have an interestingfocus to settle to green chemistry to come up with their products.For instance, there are scientists at the Los Alamos NationalLaboratory that develop computer chips by using superficial carbondioxide. The method of using the superficial carbon dioxide lowersthe amount of chemicals, water, and energy needed to manufacture acomputer chip (Matlack, 2010). More so, various pesticide producersnow shift to biological methods of pest control and lower the levelof emissions found in the pesticides. With such processes of adoptinggreen chemistry in the daily production and manufacturing processes,the results of reduced environmental degradation would be evident.However, despite the many advantages obtained from using greenchemistry, its actual internalization proves to be difficult. First,the methods of green chemistry are a trade-off among the costs ofproduction, the feasibility, and the benefits of the sales. In mostindustrial applications, the processes of adopting green chemistry donot fall under the objectives or in any visions for the industries.Furthermore, the intake of green chemistry into the various chemicalproductions and in varied industrial applications can only be anadditional improvement on an existing manufacturing process. Thegreen chemistry will act as an auxiliary process, with very fewapplications where the green chemistry is the primary productionmethod for the chemical products.
