Q & A

What is the definition of green chemistry?

Green chemistry, also known as sustainable chemistry, is a branch of chemistry focused on designing chemical products and processes that reduce or eliminate waste and the formation of hazardous substances.

Who first introduced the term 'green chemistry'?

The term 'green chemistry' was first introduced by Paul T. Anastas in 1991 as part of a special program by the Environmental Protection Agency (EPA) in the United States.

What were the environmental concerns that led to the rise of green chemistry?

The rise of green chemistry was driven by increasing environmental problems starting in the 1940s, coinciding with rapid industrial growth and the need for safer, more sustainable chemical processes.

What are the three main objectives of green chemistry?

The three main objectives of green chemistry are to create better and safer chemicals, to choose the safest methods for synthesizing these chemicals, and to minimize chemical waste.

What is the principle of 'waste prevention' in green chemistry?

Waste prevention is the principle of avoiding the creation of waste during chemical processes, emphasizing that preventing waste is better than handling or processing waste after it has been produced.

What does 'atom economy' mean in green chemistry?

Atom economy refers to maximizing the efficiency of chemical reactions, ensuring that as many reactants as possible are converted into the desired final products, minimizing waste.

How does green chemistry prioritize energy efficiency?

Green chemistry aims to carry out chemical reactions under conditions that minimize energy consumption, such as performing reactions at room temperature and pressure whenever possible.

What role do renewable raw materials play in green chemistry?

Renewable raw materials, such as those derived from natural or agricultural sources, are prioritized in green chemistry over non-renewable materials like fossil fuels, as they can be replenished and sustainably harvested.

Can you give an example of a green chemistry application in the paper industry?

In the paper industry, the use of hydrogen peroxide and tetraamido microcyclic ligand catalysts (TAML) helps decompose lignin at lower temperatures and in less time, leading to energy efficiency and reduced environmental impact.

How does the use of tamarind seed powder relate to green chemistry?

Tamarind seed powder, derived from agricultural waste, is an environmentally friendly alternative to alum in wastewater treatment, showcasing the use of natural, renewable materials for sustainable processes.

What is biodiesel B30, and how does it support green chemistry?

Biodiesel B30 is a fuel blend consisting of 30% fatty acid methyl esters from palm oil and 70% conventional diesel. By using a renewable raw material, palm oil, it reduces the dependence on fossil fuels, aligning with green chemistry's principle of using renewable resources.

What are the primary benefits of applying green chemistry?

The primary benefits of green chemistry include more economical chemical processes, improved energy efficiency, reduced waste, safer products, healthier workplaces, and protection of human health and the environment.
