Green Chemistry

“Green Chemistry” is a field of science that is based on a philosophy in the process of designing and synthesizing materials or chemicals by reducing, eliminating, or avoiding the use or synthesis of substances that cause harm and toxic to the environment. Therefore, a chemical process or step Including planning environmentally friendly operations. The heart and important mechanism of “Green chemistry” is different from environmental chemistry that studies the causes, sources, reactions, and effects on the environment including air, soil, and water, including impacts on human life activities. Due to the process of synthesizing substances or using chemicals in various ways. The chemistry at each stage of production must always be considered and remember that the chemicals will not be harmful to humans and will not harm the environment, which is an important principle of Green Chemistry. Therefore, green chemistry will focus on prevention at the root cause rather than solving problems at the end of the cause.

“Green Chemistry” looks at the roots and origins of environmental pollution problems. For example, if a chemical is synthesized or produced, it uses reactants or substances used in the reaction as well as solvents that are harmful to the environment. Finding alternative substances that are not harmful or changing the process as well as choosing solvents that do not cause pollution will be important. “Green Chemistry” considers and chooses to use it to replace old processes that cause environmental pollution.

“Green chemistry” can be embedded in various basic fields of chemistry, such as organic chemistry, inorganic chemistry, biochemistry, biological chemistry, and analytical chemistry or even physical chemistry. As well as being applied in the industrial sector where chemical processes are used in various fields such as petrochemicals, polymers, nanotechnology, etc. The same objective is to cause the least amount of pollution, but it increases the efficiency and potential of the production and synthesis process. as well as utilization.

“Green chemistry” occurred because it was found that in the production process or various activities in the industrial process all chemicals are used. Whether used as a starting raw material or used in the production process. For example, in the medical field, chemicals are involved in the matter of drug production industrial such as the plastic industry, fuel production industry, textile industry which involves the production of nylon, rayon, and polyester. Agriculture involves the production of fertilizers or pesticides, etc.

Although the products produced by these various industries are very important to our livelihood, the chemicals and steps used in the production process may cause a negative effect on the environment and health. Therefore, there is a campaign to create awareness of the environment by reducing or avoiding the use or synthesis of substances that cause harm and toxic to the environment. This is where the term “Green Chemistry” comes from.

Researchers reveal chemicals in human breath

Many animals, such as dogs, have an amazing sense of smell, but researchers have found that insects also have an excellent sense of smell. Recently, a research team from the College of Engineering Science and Science Institute from Michigan State University, USA. revealed research in the journal Biosen sors and Bioelectronics indicating that "bees" can distinguish chemicals in human breath. Biomarkers or concentrations of chemicals related to lung cancer can be detected in human breath.

 

Eco Packaging

Eco-packaging is environmentally friendly and safety packaging. It is the selection of raw materials in the production process from nature that can be decomposed or materials that can be reused.

Top 10 uses for silica gel packets

A small square envelope lay at the bottom of the snack bag. Some people may throw it in the trash along with the bag of snacks. If you take it out and look, you will find many clear, round lumps. That object is silica gel (Silica Gel), a moisture-absorbing substance. which in addition to helping to keep the snacks crisp and new Silica gel also has many other uses.
