Advance in Environmental Waste Management & Recycling is a new international journal, full of interesting & novel topics, ideas & information. It is characterized by extremely fast turnaround times (less than 4 weeks!) for articles that are of interest to the editorial board. I heartily recommend this journal for scientists in "publish or perish mode" for whom priority of publication is of paramount importance.

I thank your journal and you for publishing our research which has attracted a bigger audience within a short period of time. Of course, your journal and you, the editor rendered an excellent service to us, as authors. I appreciate very much the process of your journal that has given value for our time and work. I hope to contact you soon for the next research article.

There are no words to describe my gratitude to your journal (Opast group). Being Kansas based, the state of Superman, you are my heroes!!! It is the first time for me to be in a truthful, honest, and productive scientific relationship. My experience so far with you has shown me that I belong to a very promising, productive, aspiring, and energetic professional team. But most of all, I have to say that the journal, besides the dissemination of science, strongly supports a friendly connection with the author as a person as well. I consider myself honored to be a part of this scientific family.

I am glad to have to publish my research article in your journal. I would recommend to my colleagues to join in OPAST Membership category

A study entitled "Why are diabetic patients still having hyperglycemia despite the use of diet regulation, anti glycemic medication, and insulin?" was published by the International Journal of Diabetes & Metabolic Disorders and it was very successful because I could disseminate my ideas in the whole world using this publication and I am still using this publication in many conferences worldwide. I thank you very much to the directors and editors of this journal to help me in this work and divulgation of this other reasoning regarding diabetes diagnoses and treatment.

It was great publishing my research article in this journal as I got exposed not only in my country but throughout the world. The Editors and Editorial Board have precisely gone through the article and hence I am thankful to them.

I had the occasion to publish papers in advances in theoretical & computational physics. The process is very simple, very quick, the work is serious and of quality. I was very pleased with the service provided and I would encourage anyone wanting to publish in the field to apply to this journal.

I am so glad that when we contributed in the earlier state of your journal, we tried to provide one of our best paper because we actually respected those who are eager to work smart and diligent. Presently, your journal has consistently improved according to your vision and mission in developing science and technology.

I would like to thank the professionalism, editing skills, and the graphic design and proofreading work of OPAST authors. They responded promptly from the start, and the revisions were adequate in terms of bibliography, context, theme, and format. The financial support and assistance allowed me to publish within a reasonable timeframe. I definitely recommend this edition to others.
