“…These facilities are intended to address the existing gaps in medical waste disposal, enhance environmental protection, and mitigate public health risks. The proposed incineration method offers several bene ts, including the reduction of waste volume, mass, and hazardous content (Cai & Du, 2021;Tovkach et al, 2023). However, as with any technological intervention, the implementation of medical waste incinerators raises valid concerns about potential environmental impacts, particularly in terms of air quality degradation (Chaudhary et al, 2022;Forbid et al, 2011;Jouhara et al, 2017).…”

The increase of medical waste is a critical concern in regions grappling with limited infrastructure. Indonesia responds to this challenge by proposing a medical waste incinerator to enhance their waste management practices. However, it is the important to evaluate potential environmental repercussions, in particular air quality degradation. This study employs a Gaussian air dispersion modeling approach to analyze the dispersion patterns and magnitude of air pollutant concentrations emanating from the proposed medical waste incinerator. Our investigation is focused on a nearby existing residential area located 100 meters from the proposed incinerator stack installation to study the immediate impact. The study simulated two atmospheric stability scenarios: 'very unstable' (A) and 'unstable' (B) based on annual meteorological condition at site, highlighting the adherence of five key ambient air quality parameters—Nitrogen Dioxide (NO2), Sulfur Dioxide (SO2), Carbon Monoxide (CO), Total Suspended Particulate (TSP), and Lead (Pb)— against Indonesia's National Ambient Air Quality Standard (INAQS) within both atmospheric stability scenarios. Notably, the concentrations of Pb and NO2, while below INAQS limits, is approaching the threshold levels with peaks of 1.459 µg/m³ and 128.840 µg/m³. Although results comply with local regulation, significance of continoues vigilance in air quality management emerges.

Energy is a crucial factor for urban development. Cities have a crucial role in climate change, as they use 2/3 of the world’s energy, producing 70% of greenhouse gas (GHG) emissions. In order to reduce the large ecological footprint of the utilization of conversional energy sources (coal, gas, and oil) and enhance a nation’s energy independence (security), it is crucial to find alternative fuels. Biomass residues are characterized as a sustainable and carbon-neutral energy source. Hence, this review describes a critical assessment of not only the quality characteristics of several waste and biomass residues for bioenergy production and biofuels but also the value-added products that could be produced from wastes to enhance industry (e.g., pharmaceutical, cosmetics, packaging industry, etc.). Furthermore, the challenges and potential solutions of waste utilization for bioenergy production and the transformation of value-added products for urban sustainability are also explored. Despite the high-quality characteristics and the availability of these wastes, several critical factors should be taken into account. Biomass residues could contribute to sustainable development goals (SDG), such as sustainable cities and communities, clean energy, responsible consumption and production, the economic growth of a country, and, as a result, urban development.
