The growing interest in green chemistry requires fresh perspectives on analytical extractions. Reduced solvent consumption, alternative safer solvents, and reasonable energy demands must be balanced with traditional analytical considerations such as extraction yield and selectively. This session deals with some of the concepts behind green chemistry and discusses green solvent selection and extraction techniques. An overview of alternatives to conventional solvents, new green solvents, ionic liquids, and other solvent options will be discussed in this scientific discussion
Polysaccharides polymers: These are biological feedstock, and as such have the advantage of being renewable, as opposed to those feedstocks which are the product of petroleum. On the other hand, these have no chronic toxicity to human health and environment. Commodity chemicals from glucose: glucose is another alternative for commodity chemicals by using glucose in place of benzene, can help in minimizing the use of certain reagents with certain toxicity. The conduction of synthesis in water instead of organic solvents is more beneficial. The use of CO2 as a substitute for organic solvents already represents a tool of waste reduction in chemical industry.
Biodegradation is nature’s waste management and recycling system. It breaks down everything from yard waste to crude oil. It is a natural process necessary to keep our planet clean and healthy. “A process by which microbial organisms transform or alter (through metabolic or enzymatic action) the structure of chemicals introduced into the environment.” Basically, organic (carbon-based) material is changed through chemical processes from complex molecules into simpler molecules, eventually returning the molecules into the environment. For example, a banana peel can be reduced from cellulose to water, carbon dioxide gas, and humus in a compost pile.
Biomass is an energy resource derived from plant- and algae-based material that includes crop wastes, forest residues, purpose-grown grasses, woody energy crops, algae, industrial wastes, sorted municipal solid waste, urban wood waste, and food waste. Biomass is the only renewable energy source that can offer a viable supplement to petroleum-based liquid transportation fuels—such as gasoline, jet, and diesel fuel in the near to mid-term. It can also be used to produce valuable chemicals for manufacturing, as well as power to supply the grid. A collaborative and multidisciplinary in-depth analysis by the U.S. Department of Energy determined that the United States has the capacity to sustainably produce over 1 billion tons of biomass annually—and still meet demands for food, feed, and fiber.
Bioenergy is renewable energy made available from materials derived from biological sources. Biomass is any organic material which has stored sunlight in the form of chemical energy. As a fuel it may include wood, wood waste, straw, manure, sugarcane, and many other by-products from a variety of agricultural processes. Bioenergy is one of the many diverse resources available to help meet our demand for energy. It is classified as a form of renewable energy derived from biomass organic material that can be used to produce heat, electricity, transportation fuels, and products.
Biopolymers are polymers synthesized by living organisms. Biopolymers can be polynucleotides (such as the nucleic acids DNA and RNA), polypeptides (that is, proteins) or polysaccharides (that is, polymeric carbohydrates). This consist of long chains made of repeating, covalently bonded units, such as nucleotides, amino acids or monosaccharides. Bioplastic is a biodegradable material that come from renewable sources and can be used to reduce the problem of plastic waste that is suffocating the planet and polluting the environment. As an alternative, the use of bioplastics is being promoted, consisting in obtaining natural polymers from agricultural, cellulose or potato and corn starch waste. These are 100% degradable, equally resistant and versatile, already used in agriculture, textile industry, medicine and, over all, in the container and packaging market, and biopolymers are already becoming popular in cities throughout Europe and the United States for ecological reasons: they are known as PHA.
This product is expected to cover the needs of 10% of the European plastics market within 10 years.
Advantages of bioplastics:
They reduce carbon footprint
They are providing energy savings in production
They do not involve the consumption of non-renewable raw materials
Their production reduces non-biodegradable waste that contaminates the environment
They do not contain additives that are harmful to health, such as phthalates or bisphenol A
They do not change the flavor or scent of the food contained
Eco-friendly literally means earth-friendly or not harmful to the environment. This term most commonly refers to products that contribute to green living or practices that help conserve resources like water and energy. Eco-friendly products also prevent contributions to air, water and land pollution. You can engage in eco-friendly habits or practices by being more conscious of how you use resources. Eco Friendly are sustainability and marketing terms referring to goods and services, laws, guidelines and policies that claim reduced, minimal, or no harm upon ecosystems or the environment. Companies use these ambiguous terms to promote goods and services, sometimes with additional, more specific certifications, such as ecolabels. Their overuse can be referred to as greenwashing
VOC reduction enables better indoor and outdoor air quality, and decreases human exposure to pollutants, Dow’s low-or no-VOC solutions cost less than more traditional compounds, Dow’s low or no-VOC solutions meet sustainability requirements without compromising the quality of the product.The manufacture of computer chips requires excessive amounts of chemicals, water, and energy. Estimates indicate that the weight of chemicals and fossil fuels required to make a computer chip is 630 times the weight of the chip, as compared to the 2:1 ratio for the manufacture of an automobile.
Catalysis has come a long way and has served industry well in enabling many reactions to be done which, otherwise, would have been uneconomic or even impossible. Today chemists are faced with new challenges as concerns for the environment and scarcity of resources motivates them to look for greener processes. Biocatalysis is the main green chemistry technology adopted by the fine chemicals and pharmaceutical industries to manufacture chemicals with higher yield. Heterogeneously catalyzed processes using supported metal or molecular catalysts are still an exception.
Green chemistry emerged from a variety of existing ideas and research efforts (such as atom economy and catalysis) in the period leading up to the 1990s, in the context of increasing attention to problems of chemical pollution and resource depletion. The development of green chemistry in Europe and the United States was linked to a shift in environmental problem-solving strategies: a movement from command and control regulation and mandated reduction of industrial emissions at the "end of the pipe," toward the active prevention of pollution through the innovative design of production technologies themselves.
For a technology to be considered Green Chemistry, it must accomplish three things:
- It must be more environmentally benign than existing alternatives.
- It must be more economically viable than existing alternatives.
- It must be functionally equivalent to or outperform existing alternatives.
Green Chemistry presents industries with incredible opportunity for growth and competitive advantage. This is because there is currently a significant shortage of green technologies: we estimate that only 10% of current technologies are environmentally benign; another 25% could be made benign relatively easily. The remaining 65% have yet to be invented! Green Chemistry also creates cost savings: when hazardous materials are removed from materials and processes, all hazard-related costs are also removed, such as those associated with handling, transportation, disposal, and compliance. Through Green Chemistry, environmentally benign alternatives to current materials and technologies can be systematically introduced across all types of manufacturing to promote a more environmentally and economically sustainable future.
Green chemistry metrics serve to quantify the efficiency or environmental performance of chemical processes and allow changes in performance to be measured. The motivation for using metrics is the expectation that quantifying technical and environmental improvements can make the benefits of new technologies more tangible, perceptible, or understandable. This, in turn, is likely to aid the communication of research and potentially facilitate the wider adoption of green chemistry technologies in industry.
Environmental science is the multidisciplinary study of all aspects of the Earth’s physical and biological environments. It encompasses environmental chemistry, soil science, ecology, climatology, vegetation cover, marine and freshwater systems, as well as environmental remediation and preservation, and agriculture and land use. It also covers topics like Environmental Chemistry, Carbon footprint, Co2 capture, Greenhouse effect and many more. The natural greenhouse effect is caused by greenhouse gases which occur naturally in the earth’s atmosphere. The main natural greenhouse gases are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and water (H2O). These gases absorb and re-radiate the sun’s heat, helping to warm the planet and providing a temperature range that is suitable for life as we know it. Without these natural greenhouse gases, the temperature of the earth’s atmosphere would be approximately 34 degrees Celsius lower than it is today.
