Diretrizes para o gerenciamento de resíduos provenientes de papel na UNESP, câmpus de Rio Claro

As atividades exercidas em uma Instituição acadêmica resultam na formação de diversos tipos de resíduos entre eles um volume considerável daqueles provenientes de celulose, principalmente variedades de papel e papelão, sendo o primeiro utilizado em larga escala para a confecção de objetos para os mais variados fins, de atividades didáticas, usos para fins de limpeza, até documentos. O presente trabalho foi realizado integrado às práticas do projeto PGR (Plano de Gerenciamento de Resíduos) desenvolvido no campus da Unesp de Rio Claro, tendo como objetivo o diagnóstico do gerenciamento dos resíduos de papel e papelão, tais como as práticas de descarte, reciclagem e/ou reutilização vigentes para posterior elaboração de um manual para o gerenciamento ambientalmente correto de tais tipos de resíduos. Para esse levantamento foi elaborado um questionário (Check-list) que foi aplicado nos diferentes setores da UNESP entre Novembro de 2014 e Abril de 2015. A partir desse levantamento preliminar e da quantificação aproximada do montante de resíduos e das porcentagens reutilizadas/recicladas e as descartadas, visou-se propor melhorias no processo de gerenciamento deste tipo de resíduo. O montante de resíduos provenientes de papel gerado nos 50 setores avaliados, sendo 27 do Instituto de Biociências, 21 do Instituto de Geociências e Ciências Exatas e dois de uso comum entre os dois institutos, foi de aproximadamente 190kg de material, embora observado que na maioria das vezes os papéis tenham sido eliminados junto a resíduos de outra natureza, até mesmo orgânicos. Também foram constatadas a proporção de setores que procuram reduzir e reutilizar seus resíduos, sendo que a reutilização de papéis diversos para rascunhos e a utilização de caixas de papelão para o armazenamento de variados objetos foram as práticas mais comumente observadas, sendo apresentadas em maior ou menor grau em 62% dos setores visitados

Potencial de contribuição e importância socioambiental dos 'catadores autônomos' de Rio Claro (SP) para o programa de coleta seletiva municipal

The Urban Solid Residues are the rests of human activity, popularly known by trash and considered by population like useless, undesirable and disposable. On the other hand, for the waste pickers, solid residues are the beginning of a cycle: they see in the other's people trash the only income, an economic value. Currently, in brazilian cities, one million collectors act, alone or in cooperatives, socially excluded by the work they do. The National Policy of Solid Residues (PNRS), instituted in 2010, established guidelines to the execution of integrated residues management, with should be practiced by city halls and other governmental institutions. This policy has, besides other things, goals of residues reduction and inclusion of waste pickers in the mechanism of selective collect and recycling. However, this and other public policies created for residue management are benefic only for cooperated waste pickers. That could negatively affect most of this class, since 90% are waste pickers working in a precarious way on the country's streets. This study has for objective show that most of waste pickers that work in a precarious way on the brazilian territory has a huge potential for the solid residues recycling chain and how they should be valued for the environmental services they provide, so they can be included with dignity on the society, ensuring economic and social benefits for this workers. The methodology adopted was based on the amount of residue collected by the 44 cooperated members of the Rio Claro‟s waste pickers cooperative to estimate the potential of collect and recycling did by 210 autonomous waste pickers who are active on city streets. It was observed that the cooperative collects the equivalent of 10.2% of all recyclable residues generated by city population. However, with the potential that these autonomous waste pickers have, which together could contribute 465 tonnes of solid residues per month, or 5,570 tons a year...

Proposta de captação de água de chuva de para fins não potáveis em projetos residenciais

Water is an economic, strategic and social valuable resource of the utmost importance to society. This renewable natural resource is increasingly scarce with the growing of populations, industries and agriculture, in addition to the pollution surface and underground water and the waste have aggravated this situation. Investments in the sector of water resources so that this resource meets in quantity and quality the demand from its multiple uses, represent a significant portion of national and regional budgets. Therefore, the use of alternative sources of water capture can reduce the pressure on conventional public water supply systems. In this work was designed and executed a rain water collection system to a residence in the city of Barueri (SP), which can be applied to other residences. In this system, the rooftop of the residence was used as the waterproof and capture area. The gutter and the PVC conductors were used for driving the water to two connected reservoirs. The stored water was designed to address activities that are not potable, such as washing clothes and external areas and garden irrigation. The system showed economic viability, with 34-month return of investment time, wherein after that period, in addition to environmental and social benefits derived from the implementation of the project, the economy made with the payment of public supply rates should be considered. This rainwater capture system is inexpensive and uses materials available in the market. Therefore, its application to a greater number of households should be encouraged as a measure of sustainable water management

Diagnóstico e proposição de medidas para o controle das perdas de água no sistema de abastecimento de Guaratinguetá

Over the past two years, Brazil has been facing a major water crisis in its history and the state of Sao Paulo is the one that has been going through worst difficulties. In this scenario, all water users should do everything possible so that the consumption of water resources is carried out in a sustainable manner. In this context, the companies responsible for the public water supply must increase the efficiency of water resource management. It is indispensable combating losses in the public supply system. When there is a non-visible leak in a pipe, the wastewater volume can be high, but in this case, the water returns to nature and continues to participate in the hydrological cycle. The economic loss corresponds to the value added to the product water, which includes the intrinsic costs of exploration, processing and distribution. This damage results in a reduced availability of financial resources of sanitation companies to invest in environmentally friendly solutions. This study aimed to diagnose the water distribution system in the city of Guaratinguetá (SP), held by the Companhia de Serviços de Água, Esgoto e Resíduos de Guaratinguetá (SAEG), to propose measures to combat water loss. Among the proposed measures, there is the monitoring of losses, planning for replacement of old pipes and company awareness as a whole in relation to combat water losses
