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.

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.

A Sustainability Analysis of Different Types of Asphalts Abstract
The present work aimed to analyze ecological asphalts, aiming at their influence on the tripod of
sustainability in the social, environmental and economic spheres. The option of using eco-rubber
asphalt and EVA as a raw material for paving roads and highways is a bet for a more resistant material
that requires less nature degradation and easier maintenance. One of the main reasons for the
degradation of flexible pavement is the wear caused by the time of use, as well as the traffic of vehicles
carrying excessive loads. This study reports some alternatives to multiply the improvement of reverse
logistics of waste tires and EVA (ethyl vinyl acetate) plastics, facing problems related to environmental
impacts, which directly affect the Brazilian population. This project is important because it is directly
linked to sustainability and the development of the environment, facing renewable and suitable
alternatives to be employed, such as ecological asphalts, and their benefits. Among the benefits of
ecological asphalt we can mention the contribution to the environment by reducing the amount of
waste tires improperly discarded in nature and the durability of ecological asphalt compared to
conventional asphalt where it showed greater resistance to climate fatigue. The research used the
qualitative method being a study based on bibliographies, analyze and discuss the reuse of solid waste
and the mitigation of environmental impacts through asphalt. Ecological asphalt seems to be more
expensive than the bituminous asphalt used today, however it is environmentally friendly and its
effectiveness, durability and safety are noticeable advantages.

Solid Waste Generated by Amazon and Tapajós River Vessels: An Environmental Education Activity Abstract
Given the lack of research on solid waste generated by vessels and often incorrectly discarded, it
became clear the need for a new methodological approach focusing on the knowledge of this theme.
Thus this study was conducted focusing on the process of awareness of users of a vessel that made
the route that traveled the Amazon River and Tapajós, using an environmental awareness activity, with
results and immediate observations. From this, the waste was quantified before and after the
interventions, which occurred from the clarification of the environment, solid waste generation,
natural resources, water, among others. The research took place aboard a vessel that connects
Manaus-AM to Alenquer-PA, evaluating the before and after the intervention. Given this, it is verified
that the evaluation process achieved positive results in the minimization of solid waste generated,
ensuring that the study has immediate effect, but the intervention measures need time for
consolidation, given the responsibility of environmental education, which needs different approaches,
under different eyes and with depth of knowledge, even if it requires a long-term process. Therefore,
the importance of this type of activity is verified, aiming at the correct destination of the solid waste
generated, in any circumstance, mainly in vessels, in different rivers, considering the condition of this
natural resource. In addition, user awareness and education through environmental education is
mandatory to better understand the impacts caused by different changes over time and needs to be

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.

Waste Reuse in a food establishment for the production of organic fertilizer in Manaus - Amazonas Abstract
Organic waste has been a threat to society and the environment, both by the amount generated and
the inadequate treatment. Seeking solutions to these wastes, composting becomes an efficient
process through accelerated biodegradation. The present study aimed to analyze the reuse of organic
waste generated in a food establishment in Manaus-AM. The quantitative methodology presented two
steps, weighing for three (3) weeks daily, (i) the waste generated in the kitchen and (ii) discarded by
consumers, in addition to the total compost generated by the compost, as a basis for treatment of this
material, as way of minimizing the amount of these wastes, analyzing the productive activities of this
establishment. Given the results obtained it was observed a disposal of almost 30 kg / week, which if
estimated, can reach a value of 0.5 tons / year, for each type of disposal evaluated, totaling a value
that can reach 1 ton of organic waste disposed of by this small food establishment. Analyzing the
composting process, the data show that there is a reduction in the amount of materials generated,
due to their transformation into organic fertilizer, obtaining 50% of the total value produced from the
waste, thus indicating a solution to the problems arising from the incorrect disposal of waste. organic
matter, which is close to 54% of this waste generated in Brazil. In addition, currently about 1.3 billion
tons of food is wasted and there are on average about 815 million hungry people in the world, proving
