Título: Evaluación y propuesta de un sistema de tratamiento de efluentes cloacales aplicable al refugio San Martín Autor(es): Zárate Kachyña, Antonella Marlene Abstract: Nahuel Huapi National Park, located in the northwest of the argentinean andean Patagonia, has a system of mountain refuges, constituted by natural and cultural heritage assets of high intangible and landscape value. This system takes place in an environmentally fragile site, given its association to high-altitude streams and lagoons or to glaciers and streams, which were designed to serve a specific amount of visitors. San Martín mountain refuge, located in the proximity of Bariloche, has shown a marked increase in the number of visitors in recent years, following the tendency previously mentioned. Therefore, several field researches were carried out, where the sewage treatment system from the San Martín mountain refuge’s external restrooms were diagnosed. Through one of the field researches, it was determined that the effluents, once treated, are being discharged into a high-altitude wetland. It is important to note that, due to the saturation of the system, the wastewater has a highly deficient, reatment, negatively impacting the high-altitude wetland. These environments develop under rigorous environmental conditions, remaining covered by snow several months and exposed to low temperatures most of the year. All these factors decrease the speed of their recovery process. An analysis of several conventional and non-conventional technologies of treatment systems applicable to the site was carried out, taking into consideration field trips to several mountain refuges in the area, as well as interviews and a bibliographical analysis. The different technologies were analysed taking into account social, economic and environmental aspects, dimensioning several treatment systems and projecting the design for 10 years of use. It was determined, as a conclusion of this study, that the implementation of the wastewater treatment system known as dry toilet allows to reduce significantly the environmental risk, due to its high efficiency under extreme climatic conditions and the elimination of the effluent discharge to the environment. This technology is strongly recommended for the area of study, given that it is eco-friendly, easy to apply and maintain, and it adapts well to the mountain environment.

Título: Caracterización ambiental y propuestas de cierre del vertedero a cielo abierto de Junín de los Andes. Autor(es): Valencia Mó, Matías Abstract: Urban solid waste management is a problem that affects all populations and that has increased due to urbanizations development. Inappropriate waste management can lead to major environmental problems. Located in the town of Junín de los Andes there is an open-air landfill where, currently, no waste is available and not only action has not been taken for its proper disposal, but also, they are being buried in quarries and mounds. Different parameters in groundwater, soil and gases generated in the landfill have been sampled and analysed. In addition, methodologies have been implemented in order to determine vents tubes condition and the own composition of the soil. As a result, some dangerous to health components have been found in the environment and should be contained. It is necessary the implementation of different measures due to remediation needs, each zone features and the contaminating components found in the sampling process.

Título: Diseño de un sistema de gestión de residuos patológicos y farmacológicos domiciliarios para la ciudad de San Carlos de Bariloche y Dina Huapi. Autor(es): Sedlarik, Ian Abstract: The modern economy is based mainly on a linear model, in which limited resources are extracted, used and after fulfilling their purpose, they are eliminated. This aspect together with urbanization, population growth and consumerism affect directly the household solid waste generation, were many of them contain compounds of dangerous characteristics. As part of household hazardous waste in homes is pharmacological and pathological waste, the latter include waste of absorbent hygiene products. Household hazardous waste have multiple effects on human health and the environment, and a process of pollution can occur through various means and generate chronic diseases or even death. Based on this, it has been proposed a waste management that includes the selected recollection for these three sub-categories. Subsequently, two treatments have been proposed, being the incineration by combustion in rotatory ovens the recommended choice for pathological and pharmacologist wste, while the use of US Patent 8,177,151 B2 has been proposed by means of which the majority forming elements of the absorbent hygiene products wastes.

Título: Análisis de tratamiento y/o aprovechamiento del bagazo de cebada en cervecerías de San Carlos de Bariloche. Autor(es): Piotti, Matías Ariel Abstract: This thesis addresses the problem of barley bagasse, a byproduct of the beer brewing process, in breweries in San Carlos de Bariloche. Various alternatives for its utilization are analyzed with the goal of reducing its environmental impact and generating added value within a circular economy context. Barley bagasse contains high levels of fiber, protein, and micronutrients, making it a valuable resource for various uses. However, its high moisture content, typically exceeding 80%, favors microbial growth, which accelerates the decomposition of the material in a short period of time. This rapid degradation not only complicates its handling and storage but also limits its utilization unless appropriate stabilization methods are implemented. The thesis demonstrates that barley bagasse, often considered a problematic waste, has significant potential as a valuable resource. Adopting sustainable practices and utilizing this byproduct not only benefits breweries in terms of profitability, but also contributes to social well-being and reduces the environmental impact in San Carlos de Bariloche.

Título: Evaluar y comparar el biocombustible leña del género Pinus con otras especies locales, en el valle superior de El Manso (Río Negro). Autor(es): Orrego, Romina Silvana Abstract: Biomass is considered a clean energy source due to its role in combating climate change. The use of biomass resources can boost rural economies, creating more job opportunities and reducing economic pressures on agricultural and forestry production. However, in some Chilean cities, wood heating is one of the main sources of air pollution due to the combustion of uncertified firewood. In rural areas of the Argentine Andes, firewood consumption is deeply rooted in local traditions and culture. Such is the case in the rural area of El Manso, which will be studied in this paper. This project aims to study and compare the performance of firewood from the Pinus genus, widely available in the Andean Patagonia region, compared to local forest species such as Nothofagus, Lomatia, and Salixs pp, used for home heating. The valorization of Pinus biomass will encourage its use and reduce pressure on native forest stands.

Título: Potencialidad del matorral mixto norpatagónico para el secuestro de carbono Autor(es): Morabes, Nora Victoria Abstract: Currently, efforts related to climate change mitigation highlight the importance, among other things, of determining the amount of carbon stored in forest ecosystems as a tool for reducing greenhouse gases. The North Patagonian mixed shrubland has significant unexplored potential for carbon sequestration in its various reservoirs (aboveground biomass, soil, and roots). This study was conducted in a mixed shrubland located in El Foyel, Río Negro, Patagonia, Argentina. The study area comprised a total of 202 hectares, divided into six unmanaged stands with similar ecological characteristics, well-preserved. The objective of this study was to quantitatively estimate the potential of the North Patagonian mixed shrubland to sequester carbon in the aboveground biomass of trees. Tree species with the highest biomass and number of individuals had greater carbon retention and CO2 absorption, with the Ñire (Nothofagus antartica) being the species with the highest carbon sequestration in most stands. Similarly, to protect the countryside from potential carbon loss, all activities that reduce vegetation cover, such as logging, soil movement, and animal herbivory, must be avoided. A fire protection system must also be in place, taking into account the area's vulnerability to fires.

Título: Estimación del impacto de un hipotética liberación accidental de material radiactivo considerando contramedidas. Autor(es): Lavate, Nazarena Abstract: This integrative final project analyzed the radiological impact of a hypothetical accident at a generic nuclear power plant and the effect of implementing different countermeasures. WinMACCS was used to calculate the atmospheric dispersion of the released radioactive material and the resulting doses to the public. This same code was used to calculate the economic impact of the accident and the countermeasures. In addition, a Python programming language was developed to calculate the Individual Radiological Risk (IRR) and graph it using contour lines. Eight cases were defined in which different short-term countermeasures were applied, including sheltering, evacuation, temporary relocation, and the provision of potassium iodide tablets. In some cases, only one of the countermeasures was applied across the entire area, while in others, they were applied progressively and in different areas. When evaluating the effects of countermeasures, their complexity and costs, it was determined that the most favorable case is the one in which the population present within a circular area of 10 km around the plant is sheltered and then evacuated, the population outside this area is relocated according to an established effective dose limit, and KI tablets are supplied to 50% of the population.

Título: Diseño, ejecución y ajuste de un proyecto bioingenieril para la rehabilitación del ex vertedero de San Carlos de Bariloche. Autor(es): Hruby, Silvina Anabela Abstract: The final disposal of urban solid waste represents a serious problem worldwide. Sites destined for this purpose, in general, are landfills that lack the necessary infrastructure to control pollution caused by buried waste and consequently impact the environment, affect the health and well-being of the population. To avoid the negative aspects of landfills, they must be permanently closed and monitored. The rehabilitation measures implemented after the closure, contribute to improve the health of the population and preserve the environment. The former municipal landfill of San Carlos de Bariloche has a closure plan made in 2015 that ended with the placement of a substrate cover suitable for vegetation support, but the final stage of revegetation was not carried out.

Título: Funcionalidad del paisaje y salud del suelo en un ambiente pastoreado del ecotono bosque-estepa patagónica Autor(es): Espert, Nuria Guadalupe Abstract: Soil is a nonrenewable natural resource that harbors immeasurable biodiversity and, through its functions, provides diverse ecosystem services. Overexploitation of soil due to intensive productive activities, such as livestock farming and agriculture, has led to soil degradation, a global problem. In Argentine Patagonia, the combination of the semi-arid environment and overgrazing has promoted physical, chemical, and biological soil degradation, including changes in grassland structure (species composition and abundance). Currently, it is urgent to understand the state of soil health in order to promote sustainable grazing practices and the conservation or recovery of natural communities. In this context, the objective of this Final Integrative Project is to evaluate the organization and functionality of the landscape and soil health in a grazed environment in the Patagonian forest-steppe ecotone.

Título: Estudio del potencial impacto en la atmósfera por el uso masivo de pellets de Pinus ponderosa para calefacción doméstica en San Carlos de Bariloche. Autor(es): Douat, Guillermo Abstract: For the WHO, the main environmental risk to the health of the Latin American population is air pollution, a passive factor that causes one in nine deaths worldwide (Prüss-Ustün et al., 2016). This organization argues that air pollution is a product of human development resulting from the inefficient combustion of fossil fuels and biomass. In San Carlos de Bariloche, the lack of natural gas supply for part of the population is a problem that has persisted over the years. Furthermore, the city is characterized by large expanses of native forests and plantations with exotic species, from which large quantities of biomass could be extracted. This study studied the potential use of ponderosa pine as a bioenergy resource, in the form of pellets and chips in high-efficiency equipment, with the aim of providing a solution to the problems mentioned above.

Título: Aproximación de factores locales de emisión de CO2 del suelo en pastizales naturales de Patagonia Norte bajo ganadería extensiva Autor(es): Díaz Leviante, Macarena Julieta Abstract: By ratifying the United Nations Framework Convention on Climate Change through Law No. 24,295, Argentina assumed a series of obligations. These include reporting greenhouse gas emissions through biennial inventories, national programs containing measures to mitigate and facilitate adequate adaptation to climate change, or any other information relevant to achieving the commitments assumed. The study of the global carbon cycle (C) is a priority for understanding the consequences of the accelerated increase in CO2 concentrations in the atmosphere, as well as for designing strategies to reduce emissions and mitigate global climate change. This Final Integrative Project (FIP) aims to determine the maximum potential CO2 respiration (Rmax) from Northern Patagonian steppe soils in the context of extensive livestock farming, as this is an important activity for the local and regional economy, with soil C dynamics.

Título: Gestión ambiental del área de acampe y del Refugio Italia en Laguna Negra Parque Nacional Nahuel Huapi Autor(es): Crego, Alondra Abstract: Nahuel Huapi National Park has a large public-use area, including trails and mountain refuges. Given the increase in visitors to this area in recent years, a series of environmental impacts have emerged in the high mountains, such as soil erosion, the elimination of scarce habitats, landscape modification, changes in wildlife behavior (Dujisin Rebolledo, 2020), the risk of fires and the dispersal of exotic species, waste sources, erosion and pollution in watersheds and glaciers, and changes in the structure and runoff of wetlands and peatlands (APN, 2019). In particular, this paper seeks to develop environmental management measures in the third most visited refuge in the park, the Italia refuge (Manfredo Segre). Analyzing wastewater treatment, solid waste management, camping area use, and visitor flow during the 2019/2020 summer, it was found that it is possible to improve environmental quality and bring visitors closer to natural and cultural values under the criteria of sustainable development, from the perspective of planning and management of the public-use area.

Título: Impacto del retroceso de los glaciares del cerro Perito Moreno sobre el abastecimiento del agua de riego de Mallín Ahogado Autor(es): Clavería, Ailín Rocío Abstract: Freshwater is a valuable, scarce, and vulnerable resource that can be found in solid form in glaciers, perennial bodies of ice formed by the accumulation, compaction, and recrystallization of snow. Glaciers are capable of regulating flows and providing water during the warmest seasons of the year, functions that are jeopardized by their retreat. This final integrative Environmental Engineering project evaluates the impact of the retreat of the North and South Cerro Perito Moreno glaciers on the flow of the Pedregoso stream and on the water supply to the Mallín Ahogado irrigation system, Río Negro, Patagonia, Argentina. Available information, consisting primarily of annual surveys by the DPA (National Park of Patagonia) for the period 2012–present, was compiled and analyzed. The glaciers are in the process of retreating and decreasing their thickness. According to available measurements, they show an average retreat rate of 5.4 m/year and a cumulative retreat of 53.6 m. Historical hydrometeorological data, field surveys, and gauging were analyzed. The ecological flow of the Pedregoso Stream was determined for February at 0.315 m3/s and March at 0.246 m3/s. A series of average daily glacier discharge rates was obtained by correlating them with temperature. These range from 0 m3/s to 0.167 m3/s, with a mean value of 0.047 m3/s. The available water flow for use in the Luden Canal was obtained under a current and future scenario in which the glaciers have disappeared. Adaptation measures to the water deficit and their economic cost were proposed, based on decentralized reservoirs, efficient water distribution systems, field irrigation methods, and the need for access to drinking water for the population. Environmental education, technical advice, and the strengthening of IWRM are presented as essential tools.

Título: Evaluación de impacto del enriquecimiento de nitrógeno en suelos regados con aguas residuales tratadas de la planta de tratamiento de la ciudad de Ingeniero Jacobacci (Río Negro) Autor(es): Catenazzo, Carlos Joaquín Abstract: The reuse of treated wastewater (RTWW) for agricultural irrigation is of special interest in arid and semi-arid regions, since it reduces pressure on water resources and closes the hydrological cycle on a small and medium scale. On the other hand, water and nutrients are used for crops in environments where their availability for human activities is very limited. Although it is a growing trend at the global and regional levels, which has many advantages, there are some environmental risks that need to be monitored, including soil enrichment in different forms of nitrogen. The purpose of this work is to propose a Nitrogen (N) balance, evaluate its adjustment and propose a monitoring plan for the behavior of N, in its different forms within the system. It is hypothesized that the RTWW for irrigation will increase the concentration of Nitrogen in the soil, but at the same time, the harvest of biomass will allow maintaining the levels of mineral Nitrogen at admissible values for crops and avoiding the excessive movement of nutrients in the soil.

Título: Evaluación Ambiental Preliminar de un aprovechamiento hidroeléctrico en su fase de factibilidad en el arroyo Casa de Piedra, San Carlos de Bariloche. Autor(es): Aguilar, Katherine Abstract: This paper focuses on a potential small hydroelectric project (SHP) for a locality and analyzes it from an environmental perspective in its early planning phase. The city of San Carlos de Bariloche was chosen as the study area, as a population center that would be directly affected and benefited by the project. To determine a potential watercourse for the SHP, the Casa de Piedra stream, located west of the city, was chosen. This choice was based on three criteria: proximity to the city; favorable water resources for hydroelectric development (constant flows and terrain gradients); and the existence of a previous hydroelectric project on the stream, created in the late 1960s, which ultimately was not implemented.

Título: Diseño de un humedal de flujo subsuperficial por medio de un modelo de caja negra para tratamiento de aguas residuales para un complejo turístico post tratamiento. Autor(es): Samudio Caballero, Juan Francisco Abstract: Water, like other natural resources, is a finite resource on Earth, and it is estimated that freshwater bodies account for 3% of the land surface. Therefore, maintaining the good ecological status of natural water bodies focuses on treating wastewater before it is discharged into the natural environment and restoring the quality of already degraded natural waters. Constructed wetlands (CW) are increasingly being used for wastewater treatment. CW construction and maintenance costs are typically relatively low, and energy consumption in the treatment process is reduced. Additionally, they can retain and treat variable volumes of wastewater. Likewise, these systems enable the reuse of wastewater, thus promoting the recycling, reuse, and recovery of water resources, in addition to helping alleviate water stress and offering social, economic, and environmental benefits.

Título: Inundaciones en la cuenca del arroyo Ñireco. Medidas preventivas y correctivas, acciones estructurales y no estructurales. Autor(es): Lasso, Matías Ezequiel Abstract: Bariloche has experienced significant growth in recent decades, expanding from the city center to the east and south, occupying high-risk areas for the population, such as the Ñireco Creek basin and floodplain. The overall objective of this study is to study the hydrological characteristics and dynamics of the Ñireco Creek watershed, with the goal of proposing corrective measures to reduce flooding and erosion risks in the lower reaches. To achieve this, work was carried out in a GIS environment based on basin parameterization, storm modeling, and subsequent analysis of hydrographs generated at the stream mouth for different intervention scenarios. The results demonstrate that the proposed actions and measures have strengths and weaknesses, so it would be ideal to implement them together, provided a corresponding individual assessment is made.
