I should suggest a way to use PP waste for producing value added products so that it becomes economic to gather and processing them.
This is a wide question. Can you narrow it down by mentioning the equipment/final use you are thinking?
In fact I want to make use of remaining polypropylene from equipment that makes medical serum packages. It provides plenty of PP waste because of the different and special forms that these serums are presented in. I don't know how to use these. any mechanical or chemical method to for conservation of these valuable scraps of PP?
You mean recycling "medical waste"?? .. medical or hospital waste raises kind of red flags in human psyche and is generally incinerated.
You can convert waste-PP into thermoplastics for large volume, low returns product or convert waste PP into carbon nanotubes (dx.doi.org/10.1016/j.cej.2012.03.077)
One of my students is working on the recycling of plastics, she is working on the recycling of plastic from scrap electronic / electric equipment but she has published with another PhD student some work on PP being recycled after blending with other plastics. Look for this paper by Sandra Tostar et. al.
E. Stenvall, S. Tostar, A. Boldizar and M.R.StJ. Foreman, The Influence of Extrusion Conditions on Mechanical and Thermal Properties of Virgin and Recycled PP, HIPS, ABS and Their Ternary Blends. International Polymer Processing, 2013, volume 28, pages 541-549.
@ Sridhar: Yes, it could be considered as medical waste, but it is still clean and not shipped to the hospitals and is not used. In fact we work on the waste from medicine factories. I thought since it is clean there maybe better way to use it.
Thank you for the article.
@ Mark: Although here we just have PP from medicine factories with the same standards and not any other type of plastic, but it seems interesting. I will definitely check her article.
Thank you. I hope it helps me find other sources.
Dear Hossein: I suggest to have an screening by kneading the PP waste you have and check for mechanical and thermal properties. This will give you a good idea what are you grasping and where the reuse can be done. Good Luck!!
@Victor: I like your way. I will try that too. this way there is a better chance to find the proper reuse option. Thank you Victor. However I would need other sources to help me figure out what is the best choice based on its thermal and mechanical properties.
