Modeling of the Risk of Forest Fires for the Andean Community Picol Orcompugio, Cusco – Peru

The risk of wildfire is common in different regions of Peru, only in the Cusco region until October of 2022 there were 10 active fires (COER, 2022), the effects of them play a role in the dynamics of the ecosystems decimating the ecosystem services that in turn affect the economy in the area. The most common origin of these forest fires is the use of agricultural burning as a tool to clear and prepare the soil, furthermore, other wildfires are originated for the weather conditions because the effects of global warming on the patterns of rainfall and solar incidence (Armenteras et al., 2020). For that reason, is necessary arises models for the risk of forest fires in areas with low response capacity and high level of poverty like San Gerónimo district, specifically in the Andean community of Picol Orcopungio, because these wildfires can break out in there. The information was collected based on historical forest fires and the analysis of meteorological variability in the previously delimited area, which allowed the development of maps of temperature, humidity, precipitation, and wind speed, as inputs on the modeling of possible forest fires in the area. The results of the investigation showed valuable information on the characteristics of the Andean Community, the mapping of meteorological conditions, and the modeling of fire risk for agricultural areas, forest areas, and community areas. The investigation concludes that the characteristics of the Andean Community and the meteorological conditions of the study area present a high risk and contribute to the formation of forest fires, it also presents a risk model that allows for managing prevention and emergency operations in the Andean community

Electricity Generation from Slabs of Construction and Demolition Waste and Waste Electrical and Electronic Equipment

Many countries depend on electrical energy to be able to develop their activities, and the most advisable is to generate it from renewable energy sources. Construction and demolition waste as well as WEEE (waste electrical and electronic equipment) can be used to generate electricity. Therefore, the research aimed to generate electricity from energy slabs from construction and electrical waste. For this purpose, the waste was collected, sorted and segregated, and then the slabs were made and assembled with the mechanical part. The method of transformation of mechanical to electrical energy arising from the interaction of people through the action of stepping on the slabs was used. The results obtained indicated that a single module of 14 slabs was able to charge a 12 V battery in an average of 4 hours, and by increasing the number of modules the energy collection time is substantially reduced, as long as the flow of people is increasing. Finally, it was concluded that the use of these slab modules is quite favourable for small-scale power generation, provided the necessary conditions are met

Biomechanical Recycling of Plastic Waste Using Tenebrio Molitor Larvae

Insect larvae eat plastics and can take part in biomechanical recycling, breaking down polymers in their intestinal tract. The objective of the research was to biodegrade waste vinyl (PVC) gloves for domestic use using Tenebrio molitor larvae. For this, the mass of plastic waste was recorded on days 5, 10, 15, 22 and 28 of December 2022. The larvae were measured at the beginning and at the end of the trial and its excrements too. After excrement was analyzed by FTIR. Likewise, the most dominant bacteria were isolated from the intestines of the larvae that ate the plastic waste. The results indicated a utilization rate of 12% of the PCV, a rate of specific consumption of PVC equal to 2.41 mg/larva.day. The introduction of oxygen as a consequence of oxidation and associated granmegative bacteria in the larvae's intestines were also identified in the excreta of the larvae. Se ha development the biodegrading of vinyl glove residues that can be considered a biotechnological and ecological solutions to the challenge of plastic waste

Bioelectricity Generated by Microbial Fuel Cells from Spearmint (Mentha Spicata) and Ribbon Plant (Chlorophytum Comosum)

Clean energy such as bioelectricity, a sustainable energy, obtains electricity associated with biological processes that do not generate greenhouse gases. The research aimed to produce bioelectricity using microbial fuel cells (MFCs) that transform chemical energy stored in organic matter into electricity. Peppermint (Mentha spicata) and ribbon plant (Chlorophytum comosum) MFC were designed in the district of Yanacancha, Chupaca-Junín. For the experimental process, microbial fuel cells were built, 3 batteries for mint and 3 batteries for ribbon plant, using graphite rods as electrodes. The initial characterization of the soil used in the pile was carried out, and then the global solar radiation was measured during the operation of the pile. In the investigation, a greater bioelectricity was achieved when the pH and temperature of the soil of the microbial fuel cell were 7.04 and 10.80 °C in peppermint MFC and 6.43 and 12.83 °C in tape MFC where bioelectricity of 245.37 mV was generated, 601.15x10-6 W in peppermint MFC and 505.45 mV, 2552.52x10-6 W in ribbon MFC respectively, so the ribbon microbial fuel cell (MFC) was the most efficient for bioelectricity generation
