Local Environmental Impact From MSW
Aerobic Biological Treatment

Abstract
The present work indentifies some aspects of the environmental impact of two
aerobic biological treatments (bio-drying and composting) applied to fractions of
municipal solid waste (MSW) taking into account the odor release into the
atmosphere and its concentration at ground level. Some scenarios are presented
for the process air treatment and management: bio-filter and regenerative thermal
oxidation treatment (RTO), at different heights of release. A Gaussian dispersion
model, AERMOD, was used in order to assess the dispersion and odor emissions
into the atmosphere. Data refer to a case-study region where both the biological
plants could be constructed. A site of potential location for one of the two plants
was studied from the odor impact point of view. The case of bio-filter at ground
level resulted as the most critical, depending on the low dispersion of the
pollutants. Technical solutions for the optimization of the impact are also
proposed in this paper.
Keywords: bio-drying, bio-filter, composting, MSW, odor, RTO.
1 Introduction
In the sector of municipal solid waste (MSW) aerobic biological treatment, odor
is not related to the presence of only one compound. Thus the management of the
related problems is not easy. The interest in this problem has become more and
more relevant in the recent years because of the construction of these plants near
urbanized areas but also because of the greater attention paid to environmental
protection and human health [1–6]. However the odor perception is a complex
phenomenon with a strong subjective component.
Keywords
bio-drying, bio-filter, composting, MSW, odor, RTO.
