AEROSOL FORMATION DURING THE HANDLING OF BEECH-PLASTIC PELLETS
Abstract
Plastic waste pollution represents extensive threats to ecosystems and human health. A lot of plastic waste enters the ocean or ends on landfills, where it threatens the ecosystem. Therefore, it is crucial to find methods for its effective disposal or reuse. A significant amount of plastic can be found in personal protective equipment used to protect against viral infections and transmission, for example during the COVID-19 pandemic. This article focuses on the utilization of plastic waste by mixing it with beech sawdust and subsequently producing pellets. The pellets serve as a fuel, and aerosols were measured during their loading into a pellet hopper by an optical particle sizer in the range from 0.3 ?m to 10 ?m. The most commonly measured property of aerosols is just mass concentration which was observed. A previous study showed that the pellet combustion process did not influence aerosol formation in the laboratory with an automatic pellet boiler and retort burner. This study found that the total measured aerosol concentration increased by up to 72.6% during their handling in the hopper compared to the total aerosol concentration before the handling. However, the produced pellets represent a promising way to utilize plastic waste as an additive to wood pellets
