Abstract The meat processing industry has many unfavorable impacts to the environment in Turkey. One of these impacts is wastewater treatment. Meat processing wastewater contains large amounts of proteins, fats, nutrients such as nitrogen, and pathogenic and non-pathogenic microorganisms and viruses. The high organic and hazardous content of wastewater causes environmental challenges for the flora and fauna in receiving water bodies unless it is treated adequately. Due to these reasons, the treatment process to be implemented should be the least damaging to the environment. In this study, three treatment scenarios that include a UASB (upflow anaerobic sludge bed) reactor (Scenario-1), an advanced oxidation process that includes UV/H2O2 treatment (Scenario-2) and a membrane bioreactor (Scenario-3) have been studied for a meat processor's wastewater treatment plant. For these three scenarios, an environmental impact assessment was undertaken using the Fine-Kinney method. The evaluation results revealed that Scenario-2 has the smallest environmental impact value with 475. Scenario-1 has the highest total environmental impact value as 765. Scenario-3's environmental impact value is 637. According to the evaluation results, the UV/H2O2 process is the most applicable technology for wastewater treatment in Turkey's meat industry.

VOCs emitted by two composting static piles of biosolids coming from the “El Salitre” wastewater treatment plant (Bogotá, Colombia) were analysed during the composting process. Each pile in its sampling time was maintained with a different aeration system. The sampling was made using Solid Phase Microextraction (SPME); separation and identifications were made using Gas Chromatography (GC) coupled to Mass Spectrometry (MS). Aliphatic and aromatic hydrocarbons, chlorinated compounds, ketones, mercaptans, alcohols and amines were identified in concentrations greater than the norms stipulated by the EPA for inhalation in humans beings. The emission behavior varied according to the aeration system used.
