• Feasibility of Frying Oil After Treatment by a Biofuel Company in Manaus - Amazonas
  Abstract Waste generation has increased in many sectors given the demand and population growth. Reverse logistics comes to contribute to the return of these wastes to the production chain. In this context, frying oil is one of the most processed waste and transformed into new products, such as: biofuel, boiler fuel, soap manufacturing, concrete formwork release agent etc. Oil is one of the wastes whose recycling only happens by law, because it has low added value, unlike plastic, aluminum and copper, whose values are higher. The average oil consumption in Brazil reaches 3 billion liters per year, but only 2.5% of this total is recycled, the others are discarded in the wild. The aim of this study is to analyze Reverse Logistics at different points, seeking to describe the chain steps, from the final consumer, through the PEV and ending in the companies that will reuse the frying oil already treated. In Manaus, the logistics of frying oil is done by cooperatives and private companies, being MASSEG, the largest company in the segment. This research has an explanatory character, approaching a case study, which made it possible to observe the financial and environmental feasibility of reverse logistics for the collection of frying oil, carried out at Condomínio Shopping Manauara Center, in the city of Manaus, AM. To reverse this scenario, many companies are investing in the reverse logistics process. Procedures such as leaving drums empty so that they are filled with waste oil, separation of solid waste and water from oil, are already part of the routine of tenants that also contribute to non contamination of water bodies. The collection, transportation, filtering, decantation and commercialization of the product already treated, for fuel purposes, is performed by the company itself. Finally, the company uses part of the treated oil to manufacture biodiesel, applied to the consumption of its own fleet, with no commercialization of the generated biodiesel. Thus there is a reduction in the use and costs with usual fuels (fossils), seeking to add the culture of sustainability. Keyword: Reverse Logistics, Biodiesel, Waste.
• Piezoeletricity as an Alternative Source of Electric Power Generation in an Education Institution in the Amazon
  Abstract The development of technologies for the generation of clean and sustainable energy has brought significant changes to the energy sector in Brazil and worldwide. The newest technology is piezoelectricity, which although it has been studied for years, has not yet gained its proper space in the national and international electrical matrices. With this in mind, the present work aims to describe the process of installing a prototype carpet using piezoelectric ceramics that, through a force applied by any individual, is capable of generating enough energy for the operation of a turnstile in a HEI from Manaus-AM. The application was tested by modeling applying mathematical equations in the working of the prototype developed by APC International. Different answers were obtained considering the different dimensions for the piezoelectric parts. However, it is understood that this energy production model, treated as a new technology, presents economic viability in its implementation. One of the results demonstrates that the smaller the ceramic piece, the greater the energy production and can be adapted over time to respond to large productions. Thus, it is concluded from the calculations made that piezoelectric ceramics is an excellent alternative for the production of clean energy on a small scale, in a short time, and in the long term can reach large scale.

• Degrees of Risk of Environmental Impacts Arising from Irregular Occupations in the Northern Zone of Manaus - Amazonas
  Abstract The disordered urban growth in the city of Manaus has had serious consequences for the environment in recent years, especially towards the northern part of the city. It is extremely important to verify the environmental impacts caused by this situation, in order to define the priority areas for planning and recovery actions of the areas. Sixteen areas were identified during the study, which were divided into four quadrants to define their risk levels. The risk levels were I - low, II - medium, III - high and IV - very high. The first criterion for dividing the areas in the quadrants was to identify similar characteristics between them and the second, the proximity of the areas, considering, therefore, the size of the area, as well as the loss of vegetation cover, the state of the soil and the existence and quality of the areas. water resources near the occupied areas. It was found that the presence of streams is a decisive factor to increase the environmental risk of a occupied area, in which anthropic actions intensify natural processes. Another factor considered is related to the degree of erosive processes, therefore, the occurrence of gullies and ravines accounted for the increased risk. After accounting for recorded impacts, quadrant B, located in the Cidade de Deus neighborhood, has a high environmental risk, while quadrants C and D have medium risk. These three quadrants have streams in their areas, however, quadrant A, which has no water body, has a low degree of risk, although three of its four areas have gullies. From this analysis, it is possible to define mitigation and impact containment measures, allowing natural resources to be preserved for the well-being of everyone today and for years to come.
