The results showed that the global plastics demands are increasing by 5% every year, causing larger amount of plastic wastes generation. The quantities and characteristics of pyrolysis products were significantly affected by plastic type, pyrolysis method (slow pyrolysis, fast pyrolysis and flash ...
Techniques are described for determining the identity and toxicity of the pyrolysis products of plastics. Differential thermal analysis (DTA) and thermo-gravimetric analysis (TGA) determine the temperature at which the plastic melts, the temperature at which it goes through physical and/or chemical ...

The Pyrolysis Products of Plastics—Problems in Defining Their Toxicity Reliable studies of toxic effects and hazards of inhalation exposures to thermal decomposition products of plastics must provide good qualitative and quantitative descriptions of the exposure system, if valid data on dose-response are...
Pyrolysis of Plastic Wastes Pyrolysis of polystyrene (PS) plastic waste was investigated in this experimental work harnessing a pressured autoclave surrounded by a furnace. PS was the... K Rumlová 被引量: 4发表: 2010年 Pyrolysis of Plastics Waste Pyrolysis of polystyrene (PS) plastic waste was...
This type of pyrolysis is typically used to produce fuels, such as diesel and gasoline, as well as other useful products such as waxes, oils, and char. The types of plastics that can be processed using pyrolysis vary depending on the type of process employed. Generally, polyolefins, such ...
Chemical recycling of plastics by pyrolysis is a self-sustaining process step that does not require additional energy. It covers the relatively small energy demand to degradate the polymers into small molecules at higher temperatures through energetic utilization of gaseous and solid by-products, and ...
The plastic waste crisis: A tale of mismanagement Plastics,i.e.a subset of polymers that are typically used for commodity materials, are becoming more and more present in our everyday life as hinted by them being the most highly demanded commodity materials. Production of plastics growth averaged...
The public has started to increasingly scrutinize the proper disposal and treatment of rapidly growing medical wastes, in particular, given the COVID-19 pandemic, raised awareness, and the advances in the health sector. This research aimed to characterize pyrolysis drivers, behaviors, products, reacti...
Both catalysts have been tested in pyrolysis of a mixture of plastics which resembles municipal plastic wastes, at 440 and 500 °C in a 3.5 dm3 semi-batch reactor. The results have been compared with those of the thermal process. It has been proved that ZSM-5 zeolite has a strong effect...
