O ensino da compostagem e produção de sabão como forma de gerenciamento dos resíduos sólidos domiciliares

Introdução: O adequado gerenciamento dos resíduos sólidos domiciliares (RSD) tem se estabelecido nas últimas décadas como um importante instrumento na diminuição do lixo doméstico destinados aos aterros. A compostagem doméstica e a produção de sabão a partir de óleo usado são alternativas para a reciclagem dos RSD que, ao contrário dos lixos recicláveis, não são explorados comercialmente. Assim, o ensino dessas técnicas para a comunidade pode ser uma ferramenta útil na educação ambiental, disseminando práticas que evitam a destinação final de resíduos sólidos em aterros e desenvolvendo valores para a sustentabilidade. Objetivos: Ensinar formas de reciclagem dos RSD através de técnicas de compostagem e produção de sabão a partir de óleo usado, servindo também como instrumento para promover a educação ambiental, e conscientizar a comunidade sobre a importância de um adequado gerenciamento de resíduos. Métodos: As atividades de ensino consistiram em duas partes, unindo teoria e prática, por meio da apresentação de painéis explicativos sobre compostagem, produção de sabão, e sobre as vantagens decorrentes desses processos seguida da realização das técnicas apresentadas, com a produção de sabão em barra e líquido com óleo usado, e pela montagem de pequenas composteiras em garrafões PET de 5 litros de água mineral reaproveitados. Resultados: As atividades foram realizadas em eventos abertos a sociedade de São José do Rio Preto, tais como a Semana da Tecnologia, em outubro de 2010 e a Semana do Meio Ambiente, em junho de 2011, ambas desenvolvidas no SESC (Serviço Social do Comércio) da cidade. O público foi variado, incluindo desde aposentados e donas de casa até estudantes e profissionais de diversos setores. O interesse em anotar as metodologias explicadas culminou na idéia de produzir um material impresso que contivesse as receitas de sabão (líquido e em barra), os procedimentos e dicas de como realizar a compostagem. A convite de uma escola pública, houve também a apresentação das atividades para pais de alunos e funcionários interessados em aprender as práticas para o adequado gerenciamento dos RSD, levando à discussão das possibilidades de implantação de um projeto de compostagem na própria escola.

Proposição de modelo de logística reversa de resíduos sólidos domésticos recicláveis para o municípios de Rio Claro - SP

The approval of the Solid Waste National Policy on August 2, 2010, brought important advances on the issue of solid waste nationwide. Several requirements were imposed causing public and private sectors to direct the problem more diligently. At the same time, the growth of human consumption and the negative impacts of related activities are increasing pressure for new ways to manage wastes. This study was carried out in order to bring proposals for a new model of solid waste management in the city of Rio Claro. To do so, it was used methodologies which stick to collaborative approaches in order to co-create a new vision considering different points of view . This new proposal includes four main initiatives: the integration of a reverse logistics system and collection of recycling materials in all kinds of educational institutions; the use of a routing platform for collection of solid wastes and recycling materials; the application of a garbage fee to residents who use the collection of solid waste system; and a bonus system developed by the private sector as a marketing strategy, encouraged by the public sector, enabling residents to separate their wastes correctly and leave them in one of the educational institutions to exchange points for discounts at local markets

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

Coleta de informações para projeto de incinerador regional de resíduos sólidos urbanos (RSU)

The incineration of municipal solid waste has become a very interesting, in order that incineration reduces the amount of solid waste, which would be accumulated in dumps and / or landfill. Furthermore, it is possible to generate electrical energy by use of clean well known technology. To verify the feasibility of installing a plant for the incineration of solid waste with energy recovery, we must consider some basic requirements. For this reason, will be presented in this paper some factors that influence the project to install a plant of incineration with energy recovery.

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 gestão dos resíduos gerados em aterro sanitário

The issue of environmental impacts to human health and the generation and disposal of solid waste has led to a change of paradigms for your face, highlighting the need for sustainable management of municipal solid waste (MSW). In this context, the expansion of landfills in Brazil in recent decades makes it necessary to sustainable management of waste generated by this type of enterprise, since its implementation. The aim of this study was to perform a diagnosis of the generation of waste in a landfill, in the expansion phase, and the alternatives adopted for its management. The qualitative diagnosis was made from observations on site and the wastes were classified and quantified from August 2011 to January 2012. In the diagnosis was considered the reduction, reuse and recycle, in that order. The results of this study showed that the residue of the greatest generation was PEAD geomembranes used in the waterproofing of the landfill, reaching 7 t, followed by PVC pipes, which reached 850 kg, both destined for recycling. The largest volume of wastewater generated corresponded to the leachate, reaching 11,500 m3 , which were sent for treatment
