Abstract

Industrial processes can lead to the emission of organic chemical compounds in the environment. These compounds, usually referred to as “volatile organic compounds” (VOCs), are harmful to the environment and contribute to the air pollution of industrialized areas. Indeed, they are classified as particulate matter (PM) and are considered to be ozone precursors. During the last decades, the release of VOCs in the environment has become a major issue, leading to the implementation of specific regulations and to the development of several VOC-abatement systems.
In this study, we focused on the bakery sector, where the VOCs, mainly ethyl alcohol, evaporate during the baking process due to the high temperatures reached in the ovens and are released from the baking chamber. We performed a detailed review of existing and emerging VOC-reducing systems, classified into “combustion” and “non-combustion” control devices, among which we identified five technologies that resulted to be the most suitable for the bakery sector. We carried out technical and economic evaluations for each technology, by interviewing both technology providers and end-users of VOC abatement technologies. Finally, we determined the optimal technology as the one that allowed for reaching the best trade-off among legislative, environmental and economic aspects.
