Recycling of Mixed Plastic Waste – Is Separation Worthwhile?
The automated separation of plastic waste fractions intended for mechanical recycling is associated with substantial investments. It is therefore essential to evaluate to what degree separation really brings value to waste plastics as raw materials for new products. The possibility of reducing separation requirements and broadening the range of possible applications for recycled materials throu...
متن کاملCharacterization of Bitumen Mixed with Plastic Waste
Plastic (Polyethylene Terephthalate, PET) is now used as packaging material for a whole range of consumer products in addition to carbonated beverages. Although plastics are very useful product, but the disposal of these wastes has become a problem and is of great concern, particularly in our country. One of the solutions to the disposal of plastic wastes is recycling it...
متن کاملSorting of plastic waste for effective recycling
Separation of plastic from various types of waste streams represents one of major problematic process in energy recovery through different thermochemical processes. The sorting of plastics is a very essential step in different waste management technique. Manual sorting is suitable when plastic component are present in large amount but it is a labor intensive process. In automated sorting techni...
متن کاملMixed waste reduction in radioactivity determination by using plastic scintillators
In this work, we tested whether plastic scintillation (PS) is a suitable alternative to liquid scintillation (LS) and Cerenkov techniques for beta emitter detection. The main advantage of this alternative is the reduction of mixed waste produced as consequence of the measurement process. In addition, the quality parameters obtained with PS are as reliable as those obtained with LS and allow det...
متن کاملThe selective recycling of mixed plastic waste of polylactic acid and polyethylene terephthalate by control of process conditions
The glycolysis of postconsumer polyethylene terephthalate (PET) waste was evaluated with catalysts of zinc acetate, zinc stearate and zinc sulfate, showing that zinc acetate was the most soluble and effective. The chemical recycling by solvolysis of polylactic acid (PLA) and PET waste in either methanol or ethanol was investigated. Zinc acetate as a catalyst was found to be necessary to yield a...
