18.12.2020 · If a technology reduces or eliminates the hazardous chemicals used to clean up environmental contaminants, this technology would qualify as a green chemistry technology. One example is replacing a hazardous sorbent [chemical] used to capture mercury from the air for safe disposal with an effective, but nonhazardous sorbent.

The major application of solvents in human activities is in paints and coatings (46% of usage). Smaller volume applications include cleaning, de-greasing, adhesives, and in chemical synthesis. Traditional solvents are often toxic or are chlorinated. Green solvents, on the other hand, are generally less harmful to health and the environment and preferably more sustainable. Ideally, solvents …

Dec 18, 2020 · One example is replacing a hazardous sorbent [chemical] used to capture mercury from the air for safe disposal with an effective, but nonhazardous sorbent. Using the nonhazardous sorbent means that the hazardous sorbent is never manufactured and so the remediation technology meets the definition of green chemistry. Green chemistry's 12 principles

For example, the production of ammonia generates both waste heat and carbon dioxide, both derived from fossil fuel. One UK manufacturer pipes these to large commercial tomato greenhouses, greatly extending the season during which the plants may be grown economically.

The United States, desiring to reward and celebrate significant achievements in Green Chemistry, has given out an annual award since 1996, the Presidential Green Chemistry Challenge Award. Examples of green chemistry accomplishments listed below illustrate how green chemistry impacts a wide array of fields, from pharmaceuticals to housewares, and offer a pathway to a better world.

10.05.2014 · Green chemistry seeks to develop new processes and improve conventional production methods. Faraday has developed a plating process to make high-performance chrome coatings from trivalent chromium instead of highly toxic hexavalent chromium.

Companies DOW and BASF jointly developed a technology of conversion of hydrogen peroxide into propylene oxide (HPPO) that has significant "green" advantages over competing technologies: It uses hydrogen peroxide and propylene as raw materials, producing only propylene oxide and water. It reduces waste water by 70-80%. It uses 35% less energy.
