Today, the chemical industry is involved, directly or indirectly in the production of essential products that surround us. That is why it is at the forefront of concerns for sustainable development. In the early 1990s was born the concept of green chemistry in the United States. It aims to develop products and chemical processes to reduce or eliminate the use and synthesis of hazardous substances.
Interview with Yves Chauvin Nobel Prize in chemistry 2005The 12 recommendations of green chemistry
This green chemistry is guided by a list of 12 recommendations proposed in 1998 by Paul Anastas, director of the Green Chemistry Institute in Washington and his colleague John Warner.
Focus on prevention is to reduce pollution at source rather than having to invest in sanitation or waste disposal.
By saving the atoms used in the synthesis, the chemical industry reduced the amount of residue of reaction, or suppress them altogether.
The design of less hazardous chemical synthesis is reflected in the use of new processes to create and use low-toxic substances – even non-toxic – for human and environmental impact.On the other hand , The evaluation systems green building using natural construction , home appliances & design materials like wall fountains could be compared to a scorecard or a report card. These systems are tools to assess how the design, construction and operation of a building are environmentally friendly or “green”. Among these assessment tools include LEED ® Canada, Green Globes and BREAAM.
LEED ® Canada uses a point system to assign values in five performance categories:
sustainable sites;
water efficiency;
energy efficiency and renewable energy;
conservation of materials and resources;
indoor environmental quality products (e.g. , water fountains,
.
According to the total points he earned, a building will be classified in any of the following categories: certified, silver, gold or platinum.
From the total scenario of present ongoing world a great radical change is happening in echo field & lots of company , builders etc are supporting this project. We can hope It will not far away that all atomic , wasted materials will be demolish & world will be greenish in all respect.
