Authors: Toparceanu, Florica; Ionescu, Ioana; Kim, Lidia; Stoica, Catalina; Nita-Lazar, Mihai
Abstract: The presence of research stations, ice runways and tourism in Antarctica could have a potential risk
of anthropic impacts on a pristine environment. Larsemann Hills is a free-ice „oasis” area, nearby the ice cap, located along the Ingrid Christensen coastline, Prydz Bay, East Antarctica, with more than 150 freshwater lakes well-mixed by katabatic winds in summer. This area, especially the freshwater lakes, is scientifically and environmentally significant and it was designed ASMA 6 in 2007. The diatoms have a ubiquitous presence in oceans, lakes, freshwater streams, and soil and they are responsible for up to 50% oxygen production. Moreover, the diatoms are an indicator of the water quality, being very sensitive to anthropic impacts and climate changes. Broknes Peninsula of Larsemann Hills contains endemic freshwater diatoms to Prydz Bay or Antarctica. In the context of global warming, in the Antarctic summer 2019-2020, there was an increase in
temperature in West Antarctica to 21 degrees and algal blooms.

Authors: Tugui, Tatiana; Efros, Natalia
Abstract: The paper summarizes the research results on the development country country-specific emissions factors for the Greenhouse Gas Inventory (GHGI) for Source Category “5A Solid Waste Disposal on Land”, namely the degradable organic carbon (DOC), fraction of degradable organic carbon which decomposes (DOCf) and fraction of methane. The factors are determined based on the results of the survey on the composition of municipal solid waste, which was investigated during one year in the Republic of Moldova: from spring 2023 to 2024. The obtained morphological composition and results refer to three seasons: spring, summer, and autumn, and offer the opportunity to observe the variations among the seasons. After finalizing the survey on morphological composition, the final results will be used for the estimation of country-specific emission factors, which will allow to estimate accurately the emissions of methane from the landfilling of waste in the Republic of Moldova, necessary for the development of a policy framework and tracking the progress in achievement of NDC. It will also improve the Intergovernmental Panel for Climate Change (IPCC) methodologies and Emission Factors for assessing the GHG emissions originating from the waste sector.

Abstract: The global issue of Food Loss and Waste (FLW) is gaining increased attention from both academic and policy circles. This challenge is progressively spreading, particularly in less developed and developing nations. This article aims to address the FLW concern within grape cultivation, proposing solutions for repurposing leftover materials from the crop. The paper will depict the current understanding of FLW, outline the supply and value chain of grape crops, and conduct an intricate analysis of production quantities, imports, exports, and processing. The study draws from the IPSUS project's research, which explores techniques for reclaiming plant and seaweed proteins through recycling raw materials. Additionally, it will explore the potential for upcycling and assess the quantity and quality of FLW at various points along the value chain. To evaluate FLW in viticulture, an IoT system will measure environmental parameters like air temperature, humidity, soil moisture, and precipitation. These measurements will help estimate harvest quality and quantity, pivotal aspects within the context of food loss and waste. The outcomes of this research will underscore the significance of repurposing grape crops, opening novel avenues for agricultural advancement in Romania.

Authors: Constantin, Cristian; Popa, Georgeta Olguta; Calinescu, Simona; Tanase, Gheorghita
Abstract: In this study, the area of a biofilter representing an active area source was sampled by taking 12 odour samples from the gaseous effluent and measuring the physical parameters of the source, so that we can obtain the odour emission rate (OER) specific to the source. The odour sampling process is a crucial step in the assessment and monitoring of odour pollution. Direct measurement of odour concentration in the ambient air is often not sufficient to determine whether an activity is responsible for producing olfactory discomfort to the receptors. To observe the contribution of the source to olfactory pollution and air quality by estimating the odour concentration in the ambient air, the odour emission rate (OER) was taken into account, which is expressed in odour units per second (ouE/s) and is obtained as the product of the odour concentration and the airflow rate associated with the source. The odour emission rate was entered into the dispersion program AERMOD for mathematical modeling. In order to estimate the odour concentration in the surrounding air in the adjacent areas to the sampled biofilter, 2 mathematical models were made to illustrate the odour concentration on the site and in its vicinity in the most unfavorable weather conditions „Highest values” and „98th Percentile” to illustrate the concentration in the surrounding air excluding the 2% unfavorable weather condition
