Green chemistry, similar to sustainable chemistry or circular chemistry, [1] is an area of chemistry and chemical engineering focused on the design of products and processes that minimize or eliminate the use and generation of hazardous substances. [2]
The word GREEN in the name Green Nanotechnology has dual meaning. On one hand it describes the environment friendly technologies utilized to synthesize particles in nano scale; on the other hand it refers to the nanoparticles synthesis mediated by extracts of chlorophyllus plants. [ 1 ]
Green solvents are environmentally friendly chemical solvents that are used as a part of green chemistry. They came to prominence in 2015, when the UN defined a new sustainability -focused development plan based on 17 sustainable development goals, recognizing the need for green chemistry and green solvents for a more sustainable future.

The construction was majority funded by GlaxoSmithKline, as part of their commitment to green chemistry first announced in 2010, [3] and saw a grant of £12 million provided to the project. [2] There are five teaching and research laboratories on the first floor, [4] with write-up space for about 100 researchers.
Photoredox catalysis is a branch of photochemistry that uses single-electron transfer.Photoredox catalysts are generally drawn from three classes of materials: transition-metal complexes, organic dyes, and semiconductors.
A green source for photocatalyst synthesis refers to a material that is renewable, biodegradable, and has minimal environmental impact during its extraction and processing. [3] [4] This approach aligns with the principles of green chemistry, which aim to reduce or eliminate the use and generation of hazardous substances in chemical processes.
The Green Chemistry Initiative of California would address transparency issues by creating a public chemical inventory and requiring more stringent regulation of chemicals that may be toxic. The CGCI Draft Report suggests a green labeling system to identify consumer products with ingredients harmful to human health and the environment.
Hydrogen can be produced from water by electrolysis.Electrolysis powered by renewable energy is carbon neutral.The business consortium Hydrogen Council said that, as of December 2023, manufacturers are preparing for a green hydrogen expansion by building out the electrolyzer pipeline by 35 percent to meet the needs of more than 1,400 announced projects.
