Green chemistry is one of the modern branches of chemistry, which has recently emerged on the scene and has become one of the most important disciplines since it aims to protect the environment from human damage.
In the last decades of the 20th century, there were growing concerns about the impact of industry on the global environment. These concerns included many adverse effects on the environment, including acid rain, high greenhouse gases, pollution of river water by fertilizers and fertilizers, air pollution, ozone hole. Some of which are directly related to power generation and transport, which have caused significant problems outside the direct impact of the chemical industry.
What is green chemistry?
This term first appeared in the early 1990s by the US Environmental Protection Agency (EPA), an agency dedicated to protecting human health and the environment. This area is concerned with designing products and chemicals that reduce harmful emissions to the environment.
What is the difference between environmental chemistry and green chemistry?
While environmental chemistry is based on the effects of polluting chemicals in nature, green chemistry is based on the environmental impact of chemistry in general, including techniques and strategies to prevent pollution and reduce the consumption of non-renewable resources.
What are the benefits of green chemistry?
Green chemistry has several benefits for human health, the environment, and the economy ... but how?
First: for better health of man:
- Cleaner air: The less harmful chemicals are emitted into the air, the less damage it causes to the lungs.
- Cleaner Water: Minimizing the dumping of harmful waste into water leads to cleaner water for drinking and recreational purposes.
- Increase the safety factor for workers in the chemical industry as a result of reducing the use of toxic chemicals and reducing the use of personal protective equipment and therefore less likely to occur accidents such as fire and explosions.
- All types of products are safe for the consumer and will be available to the buyer, such as medicines that will result in less waste generation and other products such as pesticides and detergents that will be replaced by safer products.
- Safer food: This is due to the reduction of the use of toxic substances that are difficult to decompose and therefore the manufacture of pesticides that are safer for the environment and that are toxic to certain pests and not all organisms in addition to their rapid degradation after use and non-pollution to the environment.
- Lack of exposure to harmful chemicals that cause disruption of endocrine functions in the human body.
Second: for a cleaner environment
- Some harmful chemicals end up being disposed of in the environment in a deliberate manner during use, such as pesticides or unintentionally as a result of their emission during manufacturing or as a result of disposal as waste to the environment; but green chemicals decompose into harmless or reused materials.
- Reduce plant and animal suffering from harmful chemicals and use green chemicals instead of harming plant and animal health.
- Reduce global warming, reduce ozone depletion, reduce haze and smoke.
- Reduce the imbalance in the proportion of chemicals in the ecosystem.
- The use of landfills for waste, especially waste, is harmful to the environment.
Third: Economy and Business
- High production proceeds for chemical reactions using less raw material to give the same output.
- Less manufacturing steps, allowing faster processing of products, increasing plant productivity and conserving energy and water.
- Eliminate costly waste treatment and reduce its size as well as reduce the treatment methods, because treatment of materials is often a liability, since green chemicals do not need to be treated.
- Allow the replacement of used products that will be recycled and converted to raw materials with new products and ready for consumption between traders and manufacturers.
- Achieve higher efficiency by using less raw materials to give the same function.
- Lower use of petroleum products reduces the decline of these products and avoids the risk of using them and increasing their prices.
- Reduction of deforestation and trees, as well as the effects of these plants on the environment by increasing plant productivity itself.
- Increase sales, gain and offer safer products; inform the consumer by placing a more secure mark on the product.
- Increased competition between chemical manufacturers and their customers.
