Transformation of Plastic Waste into Fuel by Pyrolysis

Given the scenario of difficulty of equalizing treatment and disposal costs, environmental risks and reduction of mass and volume of waste, the pyrolysis process presents itself as a promising option of heat treatment for the most varied types of waste. The present work aims to enable the transformation of plastic waste into combustion engine fuels. And specifically, perform the pyrolysis process for fuel generation through plastic waste, and describe the benefits generated by the transformation process. The methodology used is the case study, with qualitative approach. To obtain the fuel, it was necessary to use equipment that can degrade the plastic waste by heating it, being possible with the use of a pyrolysis oven. Heating the plastic residue inside the oven without the presence of oxygen causes the residue to melt without burning, releasing vapors, which upon exiting the heating chamber and finding the condensation chamber turns the vapor into liquid, more precisely into fuel oil. However, it was noticed that the transformation of plastic waste into fuel through pyrolysis causes the reduction of the impacts generated by solid waste disposal in the environment, water and air. In addition, it enables a new form of fuel generation, since previously it could only generate fuel from oil

A Sustainability Analysis of Different Types of Asphalts

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

Energy Efficiency Analysis in a Higher Education Institution in Manaus - Amazonas

Thinking about solving the problem of high consumption and high cost in the electricity bill, this study proposes to present proposals to increase the energy efficiency of the site. In this sense, it is proposed an energy efficiency analysis of a Public Higher Education Institution in the Municipality of Manaus, Amazonas. A building survey was performed on the appliances and components of the building\u27s electrical system, as well as an assessment of electricity bills to measure consumption. In order to verify voltage, current and power, electric measuring instruments were used to elaborate proposals aiming at increasing the energy efficiency of the site. Through the results obtained during the building survey at the IES, it was possible to observe the anomalies of the systems and indicate proposals for repair or replacement of equipment to increase the energy efficiency of the building. From the results obtained from the invoice it was possible to propose a new value of demand contract and by comparing the collected data, we identified the appliances that make the electric system less efficient, in this case, the air conditioners. Recurring payment problems with overconsumption were encountered. Adhering to the proposal of a new contract value with possible annual savings of R $22,543.92 referring to the payment of the demand portion in the electricity bill. It is also proposed to replace current lamps with LED tube lamps, reducing energy consumption by 9,122 kWh / month and saving R$ 3,263.57 per month. As for the proposal presented for the HVAC system, given the exchange of existing appliances for new and energy efficient, was not viable. Despite representing a reduction of 41869.91 kWh / month, the expected investment is not paid

Analysis of pathologies caused by humidity in civil construction

In search of better comfort and productivity, man has sought information, since antiquity, about civil construction, because, as society has become more complex, knowledge about construction has become an essential skill for human beings. In this context, the present work aims to present a simplified theoretical review on pathologies caused by humidity, and added to these characteristics, to approach ways for possible solutions, seeking to remedy the different problems caused. The present study was written through a bibliographic review on the different problems caused by pathologies caused by humidity, with a focus on solutions. For this, research was carried out on the subject, through a survey of theoretical sources (journals, scientific articles, books, theses, among others) and a theoretical framework that underlies the history of civil construction and the different characteristics acquired over the years. time. Humidity is a pathology that causes some problems in construction and mainly impacts the financial management of the project, as the final value of the work can undergo major changes until the final solution of the problem. Humidity can cause fissures and cracks, compromising part of the construction structure, in addition to other problems that affect aesthetics, such as mold, efflorescence, mildew, blisters in the paint, loss of plaster and rust. As the main causes identified for the appearance of this pathology, we can mention the lack of prevention, since the lack of waterproofing products compromises the quality of the work, causing infiltrations. The lack of ventilation and high humidity in the environment must also be observed, as they generate moisture by condensation resulting in problems such as stains and mold on ceilings and walls. The hydraulic installation is also considered, since it is important that this system has the correct and necessary sealing to avoid contact of water with the structure

Diagnosis of the Basic Sanitation of the Prata Lagoon and Maresia Lagoon, Prosai-Maués Project, Located in the Municipality of Maués - Amazonas

The discussion about the quality of Environmental Sanitation (ES) services is currently highlighted because it is directly linked to the population\u27s quality of life. Assessing the scope of SA services has become an important tool for the management of municipalities and states, as it allows the adaptation to the reality of the population to improve future planning, foreseeing the expansion of SA services. The Municipal Basic Sanitation Plan - PMSB was established by Law No. 11.455 / 2007 as an important planning tool for basic sanitation services. It consists of programs, projects and actions aimed at improving the conditions of services that constitute basic sanitation: water supply, sanitation, as well as urban solid waste management and urban river water. With the accelerated urban growth in the municipality of Maués and the intense aggressions to the environment, the PROSAI-MAUÉS ES indicators were identified and diagnosed, which propose improvements in the urban, environmental and basic sanitation conditions of the municipality with the recovery of Lagoas do Silver and Maresia, which for many years have suffered from pollution around the lagoons. The lagoons in question were chosen for the implementation of PROSAI-MAUÉS, explained by the occupation of its margins by low-income population installed on stilts, the existence of flood risk points and the need for renewal of this urban fragment of tourist importance. On-site research was conducted using observation techniques and photographic recording to describe the conditions of local sanitation services. The experience of the PROSAI-MAUÉS project indicates that it is necessary to seek the institutional strengthening of the entities involved with the local society since the early stages. from the initial planning and execution to the final phase of monitoring and follow-up of the services provided by the basic sanitation works, thus ensuring the sustainability of the Program for future generations

Evaluation of the replacement of commercial coarse aggregate by Attalea funifera Martius (Piaçava) in concrete manufacturing

In recent decades, technological advances and increased urbanization have instigated remarkable growth in the construction industry, and consequently an increase in environmental impacts both in obtaining raw materials and in the disposal of construction waste. Some studies are being carried out in Brazil for the application of natural fibers as a reinforcing element to produce concrete. According to these facts, the focus of this work is to comparatively evaluate the mechanical strength of commercial concrete with concrete produced with piaçava fiber sludge. Attalea funifera Martius, commonly known as piaçavas, is a solitary, thornless, erect, caulescent palm from the Aracaceae family. It reaches an average height of 8 to 15 meters with a stem diameter of 20 to 25 cm, having 8 to 10 leaves, each 9 meters long. Ten specimens were produced to carry out compression tests. Water, common Portland cement (CP I), sand, gravel and piassava obtained in the municipality of Barcelos-AM were used in the preparation. After curing the specimens, compression tests were carried out until the specimens ruptured. We also observed that the most resistant specimens were those produced with the addition of crushed stone, since the resistance of the specimen with crushed stone was approximately 22 MPa against 19 MPa of piaçava concrete. The main conclusions verified is that with the use of piaçava in the concrete mixture there is a drop in mechanical resistance, despite being a material that presents resistance to cracks, it does not have the same capacity as concrete with gravel as a coarse aggregate

Evaluation of environmental changes as a function of climatic variables from 2008 to 2018 in the city of Manaus - Amazonas

El Niño intensifies the temperature increase in the Amazon region, causing heat and extreme drought in much of the Amazon, in Manaus the process of urbanization intensifies the temperature increase of the city. This study aims to perform an analysis of climatological variables of the city of Manaus-AM, from January 2008 to December 2018, through the maximum and minimum temperature, precipitation and relative humidity in order to show the increase in temperature through statistical analysis showing the temperature. year of greatest impact. According to the results obtained, in 2008 Manaus recorded the lowest minimum temperature in the period being 23.4 ° C, characterizing the minimum maximum temperature with 32 ° C, it is noted that due to the presence of the negative phase of ENSO ( La Niña) in 2008 the precipitation level in the region was high, contributing to the low temperatures and the relative air humidity averaged 87%, and the highest annual average of the maximum and minimum temperature in the study period occurred in 2015. , being 33.5 ° C and 25.7 ° C, due to the positive phase of ENSO (El Niño), temperatures in the capital were high, with little precipitation during the year directly impacting the relative humidity (75%). . Therefore, the positive / negative ENSO anomalies had a major influence on the climatic variables in the year 2008 and 2015, characterizing low temperatures in 2008 and high temperatures in 2015
