TRACK 1: Green and sustainable chemistry
Green chemistry competently uses raw materials (renewable), removes wastes and avoids the use of toxic or precarious reagents and solvents in the manufacture and application of chemical products. It plays an important role in attaining sustainability.
Catalysis has an important key role in green chemistry. It is the process which increases the rate of chemical reaction by adding a substance called catalyst. The designing and using of new catalysts and catalytic systems are together attaining the goals of environmental protection and economic benefit.
TRACK 2: Basic Principles in Green Chemistry
Basic principles of green chemistry include prevention, less hazardous chemical synthesis, safer chemicals designing, use of inexhaustible or renewable feedstocks, derivatives reduction, catalysis, degradation, analysis for pollution prevention, safer solvents and auxiliaries etc. These principles allow scientists and engineers to preserve and benefit the economy, people and the planet by innovative ways to reduce waste and conserve energy. They are also helpful in discovering replacements for harmful substances.
TRACK 3: Waste reduction, reuse and recycling
Waste reduction, also known as source reduction, is the method of using less material and energy to reduce waste generation and preserve natural resources. Some of the ways to reduce waste include:
-
Using reusable materials
-
Purchasing wisely and recycling
-
Composting
-
Restraint the use of paper
Reuse is defined as the practice of using a material over and over again in its present form. It is the second preferred waste management alternative after waste reduction method.
Recycling is the process of collecting waste and processing those materials and turning them into new products instead of throwing them away as trash.
TRACK 4: Hazardous Waste Management
Hazardous waste management is the process of collecting, treating, and discarding of waste material. This waste material when improperly handled, can cause significant harm to human health and to the environment. The improper storage and disposal of hazardous waste frequently pollutes surface water and groundwater supplies which results in water pollution and can also be a source of threatening land pollution.
An analytical method or technique is a method which is used to determine the concentration of a chemical compound or element in a sample. There is a very broad variety of methods used for analysis which afford different degrees of sample devising and instrumentation.
As there is a growing interest in green chemistry it needs modern views on analytical extractions. Reduced solvent utilization, safer solvents, and cheap energy demands should be balanced with former analytical issues.

The Green Chemistry provides:
-
A huge range of challenges to those who follow chemistry in trade,

Green chemistry also plays a major in developing innovatory drug delivery methods which are less toxic and more useful, effective with minimum side effects and could help millions of patients
In the past years, for the production of Adipic acid industrially, benzene is used as a beginning material (Benzene is one of the basic chemicals for industrial reactions and a solvent). It is known that it derives mainly from the refining processes of the petrochemical industry. Later the starting material became cyclohexanone or a mixture of cyclohexanone and cyclohexane. For the oxidation process it was used nitric acid, producing toxic fumes of nitric oxides, which are also responsible to the greenhouse effect and the destruction of the ozone layer in the stratosphere. It was certain that the method had to be changed again with more environmentally cordial reactions.
TRACK 9: Green Chemistry Technologies in Food Manufacture & Processing
Green food production often suggested the organic farming practices a few centuries ago. This type of organic farming uses a small area of land for crops and another area for grazing cattle. Farm entities were almost always independent with no use of pesticides/ herbicides and the only manure was used as fertilizer.
Primary, secondary, and tertiary processing techniques are discovered to produce value-added foods and ingredients. Primary processing techniques like cleaning, sorting, and milling are used as first step in processing.
