Diagnóstico do plano de gestão de resíduos sólidos do município de Osasco (SP)

The management of solid waste has been a great challenge to public managers both because of its high operational costs and increasing waste generation. Besides environmental and public health harm, it involves high costs to be mitigated. It is necessary to seek solutions that focus on, amongst other matters, economic efficiency for a healthy environment. This could be reached with sustainable development, which has proven itself as an alternative model of development to the actual one in place. In order to ensure that sustentability is the goal of an activity, it is necessary to establish goals and to evaluate a system in order to track opportunities and correct possible mistakes, that is, it is necessary to elaborate a Waste Management Plan. However, in order to establish goals, it is also necessary a good description of the management of solid waste, thus diagnosis is a core aspect in the building of an specific law, as it will allow for the knowledge of the actual status of solid waste collection in Osasco town, showing what progress has been made in recent years, identifying current problems and generating the foundations to build future perspectives in the area. The present work has seeked to elaborate a diagnosis on waste management in Osasco municipality, presenting places for consultation and analysing how it meets the current legislation in place, enabling it to serve as a model for the elaboration of other diagnosis in other Brazilian municipalities

Análise sobre a importância do gerenciamento de resíduos de construção e demolição na universidade

With the growth of settlements and the consequent rise in civilian buildings, there was a need to allocate appropriately the waste arising from construction and demolition. Failure to meet the standards set about building waste generate social, economic and environmental impacts of remediation difficult. This study aimed to attend the importance of holding management programs involving the waste of construction and demolition at the University by the resulting environmental, economic and social benefits, and analysis of the main stages of Waste Management of Construction and Demolition, whose based on the National Solid Waste Policy, as well as verification of the importance of implementing these steps in the design of works, assisting in future studies of this type of waste and the problems accompanying the University

A gestão dos resíduos sólidos no município de Bauru - SP

The destination of urban solid waste has became a very relevant theme because of the fast growth of cities. Bauru, a strategically located municipality, needs solutions for that problem. This research aims to show solid waste management in Bauru through a survey of the selective or regular garbage collection programs, treatment and final disposal of the waste. To do so, a questionnaire with 85 questions was used about solid waste management in the municipality and visits were made to the solid waste collection and disposal sites. Bauru has a bad selective collection program and very significant clandestine disposal of Hazardous waste. Furthermore, it doesnot treat hospital waste and has a deficient final disposal landfill.

Caracterização dos resíduos do processamento de mandioca para produção de bioetanol

Aiming to get the best economic advantage in ethanol production from cassava roots, this study presented a physiochemical characterization from two different types of solid waste in two types of processing of the raw materials in manufacturing ethanol. The processing of cassava roots begins with the disintegration and washing the roots with the addition of 20% more water to obtain a pulp which was treated and stirred in the reactor while adding enzyme α-amylase at a temperature of 90°C for 2 hours. Then we performed a pH adjustment while lowering the temperature to 60 ° C with the addition of the enzyme amiloglucosidase and then stirring for 14 hours. The hydrolyzate obtained was the source of two types of waste which are: i) Solid residue obtained after filtration of the hydrolyatze and ii) Solid waste obtained from filtering wine after alcoholic fermentation of the hydrolyzate with the addition of a dried yeast strain Y-940 manufactured by MAURI OF BRAZIL SA (2%) at a temperature of 25º C. The results of the laboratory analysis showed that the byproducts derived from the hydrolysis and fermentation showed very similar chemical compositions. With levels between 39 and 41% fiber, 0.5% lipids, 20 and 30% carbohydrates, protein 0.5 and 1.50, 6 and 8% acidity, and 20 and 30% soluble solids.

Investigação da condutividade hidráulica dos solos de uma área de aterro de resíduos sólidos urbanos por meio de ensaios de campo e laboratório

A contaminant plume due to leachate infiltration was found in the solid waste landfill from Bauru, SP. The soil hydraulic conductivity (K) is an important parameter to understand the moving of this plume. This paper intends to show representative K values for the soils that occur in the vicinity of this landfill determined by field and laboratory tests. There are four soil types in the area: colluvium, alluvium, sandstone residual soil and the sandstone. Laboratory tests were performed using constant and variable head in rigid and flexible wall permeameters. Slug tests and hydraulic conductivity tests with the Guelph permeameter were also carried out in situ in the area. Representative K values of 3.7x10-7 m/s for the saturated zone and 2.4x10-8 m/s for the unsaturated zone were determined for the residual soil. A K value of 5.3x10-5 m/s was obtained for the colluvium soil. A great variation of K with depth was observed for the alluvium and the assumed average values for the saturated zone were 7.9x10-7 m/s and 1.1x10-4 m/s for the unsaturated surficial layer. An average K value of 3.3x10-8 m/s was determined in laboratory for the sandstone and it was assumed representative for this material.

Diagnóstico e proposta de diretrizes para o gerenciamento de resíduos sólidos no município de Rio Claro (SP)

Over the last few years, Brazil has some problems related to the management of solid waste, mainly related to the final disposal of materials, resulting in serious environmental risks to the municipalities that suffer from this type of situation. Poorly designed landfills and weak management systems after the termination of their employment, for example, is currently showing as a major problem for urban expansion and the subsoil of these sites, endangering all the environmental quality of the areas where they are located . Because of this scenario, this work produced a diagnosis of the current situation of the management of solid waste in the city of Rio Claro (SP) from its generation, through selective collection and sorting, as well as its final destination, in order to propose a reflection on current form management, in order to present some guidelines based on Federal Law 12.305 / 2010 - National Solid Waste Policy for improvement of this issue in the city. Although the situation found in the city can be considered reasonable for good, there is a need to improve and how to manage, especially in the operational issue of selective collection and also the participation of society in the category Environmental Education, converging in the search for improvements to the common good
