Green Industry is producing environment friendly products or products which should help improve nature conditions to better. And also during working process cause minimal damage to environment.

The green industry is focused on eliminating or significantly reducing dependence on oil, green house emissions, and toxins. With the more and more serious environment issues, green industry has become the top industry. It applies in all industry, mining machinery industry, chemical industry, road construction, agriculture and so on.
Gold mining is one of the great mining industry. Nowadays, gold mining industry goes into green industry.
Mining for gold has traditionally been viewed as a toxic business that harms the environment leaving mercury and other harsh chemicals in the atmosphere. However, this view is beginning to change as gold mining practices turn to fair trade. The new fair trade standards set social, environmental, and economic measures to eliminate child labor and minimize the use of toxic chemicals such as mercury and cyanide. The major goal of this movement is to avoid the negative impacts that mining causes in the environment while also aiming to help the millions of people who depend on the gold mining industry for employment.
Many companies are already beginning to produce under the fair trade standard promising customers that their gold products are ethically sourced and produced with no mercury or cyanide. Training miners to become more environmentally responsible has been a key objective for fair trade companies that hope to create more sustainable business practices. After all, extending the useful life of a gold mine is not only advantageous to the environment but also to the business itself. Many fair trade gold businesses in South America are going a step further by increasing the salaries of their workers, almost doubling the previous average pay. This will dramatically help the workers and their families who depend greatly on the gold mining industry.
