Given the importance of science and technology in today's world and the need to turn science into wealth, especially in our beloved homeland of Iran, the publication "Green Technologies" aims to promote science, information, culture and also orient elites, researchers and those interested in innovation Science, research and technology have been published on the challenges of sustainable investments in various chemical industries and the advancement of the principles of "green chemistry" and "sustainable technologies". This publication provides a unique context for the publication of articles, review articles, innovative and innovative views and opinions on the development of sustainable alternative technologies. Green chemistry is the use of a set of principles that reduce or eliminate the use of hazardous chemicals or their production in the design, manufacture and application of chemical products.
The goals of green chemistry include the use of renewable sources, the use of safer raw materials and reaction conditions, the design of healthier and more degradable chemical materials and products after application, increasing the efficiency of atoms or in other words increasing the efficiency of chemical processes, increasing interest Energy efficiency, prevention of waste production and moment-by-moment analysis of the process to prevent the formation and removal of by-products, efficiency of catalysts, use of recyclable raw materials, and reduce the likelihood of adverse events.

Topics covered in this publication include:

1. Design new chemicals and products, greener and safer
2. Development of environmentally friendly paths in the field of process synthesis that leads to value-added products
3. Use of innovative technologies in new green industrial processes
4. Use of sustainable resources
5. Use of biotechnology-based alternatives in chemical methods
6. new energies
7. Renewable energy from a chemical point of view
8. Design methods and tools for measuring environmental impacts and application in real samples
9. Life cycle assessment

In this regard, all researchers, thinkers and innovators at home and abroad are invited to send their research articles to the Journal of Green Technologies affiliated to the University of Tehran in order to achieve these goals. Received articles according to criteria such as quality, how to analyze, how to comment, the results obtained and also considering the aspects of innovation, application, scope and their comprehensiveness, after judging in the editorial board and It will be decided whether to accept or reject it.
