A socio-economic based survey of household waste characteristics in the city of Dublin, Ireland. I. Waste composition

Resumo: O objetivo do presente trabalho foi aplicar e avaliar uma proposta didática sobre pilhas, baterias e lâmpadas fluorescentes, no ensino de Ciências, direcionada a estudantes do Ensino Fundamental de duas escolas públicas da cidade de Jaciara-MT. A pesquisa se baseia em uma abordagem qualitativa, tendo como instrumentos de coletas de dados: questionário, observação e diário de campo. Para o planejamento das atividades propostas, os estudantes foram investigados sobre as temáticas, por meio de questionários, de forma a verificar os conhecimentos prévios a respeito dos riscos ocasionados pelo descarte inadequado, destes materiais. Para evidenciar os riscos do descarte inadequado, foram utilizadas duas aulas expositivas/dialogadas e um desafio para o recolhimento dos materiais, que apresentou grande diferença, entre as escolas. Observou-se, por meio das respostas, que a maioria dos estudantes descartam suas pilhas, baterias e lâmpadas fluorescentes, no lixo doméstico, por não saber dos riscos que estes materiais podem causar à saúde e ao meio ambiente, por possuírem metais pesados que são liberados, no caso das pilhas, quando começam a enferrujar e nas lâmpadas fluorescentes, quando são quebradas.Palavras-chave: Descarte inadequado. Pilhas e baterias. Lâmpadas fluorescentes. Abstract: The objective of the present work was to apply and evaluate a didactic proposal on batteries, batteries and fluorescent lamps, in the teaching of science, directed to students of the elementary School of two public schools of the city of, The research is based on a qualitative approach, having as instruments of data collection, questionnaire, observation and Field Journal. For the planning of the proposed activities, the students were investigated on the subjects, by means of questionnaires, in order to verify the previous knowledge about the risks caused by the inappropriate disposal of these materials. To highlight the risks of inappropriate disposal, two expository/dialogue classes were used and a challenge for the collection of materials, which showed great difference between schools. It was observed, through the replies, that most students discard their batteries, batteries and fluorescent lamps in household waste, because they do not know the risks that these materials can cause to health and the environment, because they have heavy metals that are Released, in the case of batteries, when they start to rust and in fluorescent lamps, when they are broken.Keywords: Improper disposal; Batteries; Fluorescent lamps.

In Malaysia, waste management via recycling is highly promoted, however, recycling bins are not fully utilized as almost all the recycling bins provided are filled with other wastes. As institutional waste is a part of municipal solid waste (MSW), this composition study will be crucial to obtain a conventional management of the waste. In other words, waste composition studies are vital for a more effective and proper management of the waste generated. Hence, the objectives of the research are to analyse the trend of the recycle waste composition obtained during both semester session and semester break and to determine the recycle waste composition collected at UiTM engineering complex. Sorting of the solid wastes from the recycle bins are done manually before weighing of each waste category. The trend shows that paper has the highest composition both during semester session and semester break which is at 65% and 84% respectively followed by plastic bottle with 25% and 13% and aluminum can at 10% and 3%. A sample of recyclable wastes is taken from each recycle bins to the instrumental analysis laboratory for ultimate analysis. The ultimate analysis result shows 43.68% carbon and 1.27% nitrogen for paper wastes, which give a C/N ratio of 34.67. This indicates that paper wastes are compostable when mixed with yard wastes. In determining the economic benefits of recycling, potential revenue of RM78.37 can be obtained from a 10-week period of study and hence, if recycling practice is made compulsory, the revenue can be increased.

This article presents a reflection on the past and current history, uses, and significance of the Luiz Rau creek to the municipality of Novo Hamburgo, Rio Grande do Sul. Its waters have always been important to the region, quenching the thirst of the local population and their livestock and providing venues for shared social interactions, but also as a destination for municipal industrial and household waste, which has polluted the waters of the creek. Our primary objective is to present and discuss these aspects with the purpose of elucidating the historical importance of this watercourse to the city of Novo Hamburgo. Toward that end, we conducted an exploratory survey to obtain the necessary inputs for such a discussion. We also employed texts from the now-defunct Jornal 5 de Abril and from Jornal NH, the highest-circulating newspaper in the region, to illustrate some situations experienced by the community. We found that municipal waste continues to be dumped into the creek, which has made it rather unloved by the local residents, but it remains firmly present in their daily lives.

Waste has become a problem that is really worrying everywhere. If you pay close attention, there are indeed a number of factors that cause waste problems to become serious. First, population growth. Second, more and more instant food with plastic packaging. Third, the habit of littering, the habit of consuming instant food in packaging, to the habit of throwing garbage without sorting between organic and non-organic waste will damage the ecosystem. The same problem is also experienced by Berbek Village in Sidoarjo Regency, the problem of waste and flooding that is always faced by the city cannot only be the responsibility of the government, but the community as one of the producers of household waste should always help reduce the amount of waste. Thisneeds to provide an understanding to the community of environmental concerns, especially regarding household waste management and water conservation for the future based on water conservation. The results achieved from this activity are that the village community is aware of and understands the importance of a clean environment, there is no garbage scattered, puddles or floods can be reduced, and are able to practice independent waste management methods.
