WASTE RECYCLING POLYOLEFINS PROCESS IMPLEMENTATION IN A GRANULATED PRODUCT AT JSC «ANGARSK POLYMER PLANT»

Implementation of a Waste Oil Recycling Program

As federal, state, and local regulations regarding waste disposal become more stringent, the need to address current disposal practices for waste aircraft engine lubricants and other fluid wastes has become a major issue. The purpose of this Air Force sponsored study [ I ] is to examine recycling as an alternative to current disposal methods and the steps required to implkment and monitor recyc...

Recycling Techniques of Polyolefins from Plastic Wastes

Disposing of plastic wastes to landfill is becoming undesirable due to legislation pressures, rising costs and the poor biodegradability of commonly used polymers. In addition, incineration meets with strong societal opposition. Therefore, recycling either mechanical or chemical, seems to be the only route of plastic wastes management towards sustainability. Polyolefins, mainly polyethylene (LD...

The Use of HyperSpectral Imaging for Quality Control in the MDS-based Recycling Process of Polyolefins

The separation of pure polyolefins, polyethylene (PE) and polypropylene (PP), from post-consumer plastic waste is of increasing interest in the last years according to market requirements for their further recycling. In this paper new analytical inspection strategies, based on HyperSpectral Imaging (HSI) in the VIS-NIR and NIR fields (400-1000 and 1000-1700 nm, respectively), have been investig...

Novel waste printed circuit board recycling process with molten salt

The objective of the method was to prove the concept of a novel waste PCBs recycling process which uses inert, stable molten salts as the direct heat transfer fluid and, simultaneously, uses this molten salt to separate the metal products in either liquid (solder, zinc, tin, lead, etc.) or solid (copper, gold, steel, palladium, etc.) form at the operating temperatures of 450-470 °C. The PCB rec...
