Abstract. To characterize potential air pollution issues related to recycling facilities of waste plastics, volatile organic compounds (VOCs) emitted from melted and waste plastics pellets were analyzed. In this study, laboratory experiments were performed to melt and waste plastic pellets under various temperatures (150, 200, and

Emission factors for selected volatile organic compounds and particulate emissions were developed during extrusion of commercial grades of propylene 

Adams et al. Volume 49 January 1999 Journal of the Air & Waste Management Association 51The substances targeted for monitoring included par-ticulate matter, VOCs, light hydrocarbons

Hazardous compounds emitted during the plastic melting process were analyzed to indicate potential air pollution issues associated with recycle plants for waste plastics. These hazardous compounds might be not only from polymer degradation but also from additives and print ink. To confirm what are emitted from them, melting experiments were conducted (150, 200 and 250°C, in air or N2) and

Intertek has been accredited for material testing by automotive market leading OEM (s) and works with customers on Automotive VOC issues to minimize problems before they arise in the field, providing Automotive VOC testing and aldehyde-ketone emission testing for materials and products. Gaseous VOC constituents emitted from test samples are

This paper proposes a strategy to interpret emission experiment results from consumer products and assess the corresponding potential risk. It focuses on 14 common VOCs. The identification of the polymer type of 41 plastic articles was first performed by pyrolysis coupled online to gas chromatography with mass spectrometric detection (pyr-GC/MS).

Introduction Polypropylene versatility became it one of the most important reprocessing, particularly their lost in terms of emissions of volatile thermoplastic materials nowadays, with several applications as organic compounds (VOC). commodity plastic or as engineering material 1.

Polypropylene, as a commodity recyclable thermoplastic, is studied in this research to evaluate the potential environmental impact resulting from volatile 

Models are needed to simulate VOC emissions from on the emissions of VOCs from carpets with polypropylene backing, while this type of carpet is.

Unstabilized PP (U-PP) and stabilized PP (S-PP) resins, simulating recycled materials prone to degradation, were evaluated for total VOC emissions generated during multiple melt reprocessing by

The loading particulate emissions are controlled by fabric filters guaranteed to reduce the particulate emissions to less than 0.01 grain/scf. The vent gas to the control device during loading is expected to be a maximum of 6800 scfm. Hourly particulate emissions are determined to be: lb hr grain lb scf grain hr scf

Changes in the molecular weight of the copolymer polypropylene were analyzed via the Chain Scission Distribution Function (CSDF) procedure and

It is estimated that over 170 polystyrene foam manufacturing plants are located in non- attainment areas. National annual VOC emissions from this source category are estimated at 25,000 short tons per year. Approximately 68 percent of source facilities identified in this report are located in ozone non- attainment areas.

The VOC's included aliphatic (ethane, ethylene, propylene) and oxygenated compounds (aldehydes, ketones and carboxylic acids). The most common components found were particulates and VOC's, meanwhile oxygenated compounds appeared in lower concentrations, with emission rates directly proportional to the extrusion temperature.

The VOC's produced are a mixture of the following: Aliphatic hydrocarbons: alkane, alkene. Aromatic hydrocarbons: benzene, toluene, xylene. Aldehyde: formaldehyde. Polycyclic aromatic hydrocarbons: benzo (a)pyrene. Some materials have other specific groups e.g. PVC polymers generate HCl, 2 component epoxy polymers yield amines and PET generates
