RESUMEN Objetivos: describir los elementos promotores de satisfacción e insatisfacción en el trabajo de recuperadoras de materiales reciclables y realizar acción de enfermería enfocada en tales elementos. Métodos: estudio cualitativo, convergente asistencial, realizado con recuperadoras trabajando en cooperativa. Datos obtenidos en 2015 mediante observación participante, entrevistas semiestructuradas y grupo de convergencia. El análisis contempló las fases Aprendizaje, Síntesis, Teorización y Transferencia. Resultados: emergieron cuatro categorías que ilustran experiencias de satisfacción e insatisfacción relativas a la identificación con las tareas y el contenido del trabajo, ganancias materiales y personales obtenidas con la recuperación, el prejuicio, la desvalorización y dificultades con las relaciones interpersonales. Esta última, por su significatividad, fue objeto de una acción de enfermería. Conclusión: el estudio contribuyó a mejorar conocimientos y posibilidades de asociación entre la realización de la investigación y la atención de enfermería a trabajadores.

RESUMO Objetivos: descrever os elementos promotores de satisfação e insatisfação no trabalho de catadoras de materiais recicláveis e realizar uma ação de enfermagem focada nesses elementos.

A produção de dados ocorreu em 2015 por meio de observação participante, entrevistas semiestruturadas e grupo de convergência. A análise contemplou as fases Apreensão, Síntese, Teorização e Transferência. Resultados: emergiram quatro categorias que ilustram vivências de satisfação e insatisfação relacionadas à identificação com as tarefas e com o conteúdo do trabalho, ganhos materiais e pessoais obtidos com a catação, o preconceito, a desvalorização e dificuldades nas relações interpessoais. Esta última, devido ao seu destaque, foi objeto de uma ação de enfermagem. Conclusão: o estudo contribuiu para o avanço de conhecimentos e possibilidades de associação entre a realização da pesquisa e do cuidado de enfermagem com trabalhadores.

RESUMEN

The volume of waste generated annually in concrete plants is quite large and has important environmental and economic consequences. The use of fresh concrete recyclers is an interesting way for the reuse of aggregates and water in new concrete production. This paper presents a study carried out for over one year by one of the largest ready-mix concrete producers in Brazil. This study focused on the evaluation of two recyclers with distinct material separation systems, herein referred to as drum-type and rotary sieve-type equipment. They were evaluated through characterization and monitoring test programs to verify the behaviour of recovered materials (aggregates, water, and slurry). The applicability of the recovered materials (water and aggregates) was also evaluated in the laboratory and at an industrial scale. The results obtained with the two types of recyclers used were equivalent and showed no significant differences. The only exception was in terms of workability. The drum-type recycler generated fewer cases that required increased pumping pressure. The analysis concluded that the use of untreated slurry is unfeasible because of its intense negative effects on the strength and workability of concrete. The reclaimed water, pre-treated to ensure that its density is less than 1.03g/cm(3), can be used on an industrial scale without causing any harm to the concrete. The use of recovered aggregates consequently induces an increase in water demand and cement consumption to ensure the workability conditions of concrete that is proportional to the concrete strength level. Therefore, the viability of their use is restricted to concretes with characteristic strengths lower than 25MPa.

RESUMEN

O objetivo do presente estudo foi avaliar a quantidade e o grau de segregação dos resíduos sólidos orgânicos (RSO) gerados em 14 estabelecimentos que preparam e servem alimentos em um shopping center no município de Porto Alegre - RS. Em quatro dias não consecutivos, os resíduos gerados nos estabelecimentos foram coletados para avaliação, resultando em 180 amostras e geração diária média de 421 kg de RSO. Considerando que estes resíduos são destinados à alimentação animal, determinou-se o grau de conformidade na sua segregação, através da observação e manuseio dos conteúdos de cada amostra. Verificou-se que apenas 82 (46%) amostras estavam de acordo com os critérios de segregação previamente estabelecidos, não sendo observada diferença (P=0,189) entre os estabelecimentos. O alto índice de segregação em desacordo demonstra que há necessidade de capacitação continuada junto às pessoas que atuam nestes ambientes.(AU)

This study aimed at quantitatively and qualitatively assessing the solid organic waste (SOW) produced by 14 food establishments in a shopping center. In 4 days, 180 samples were collected, with each establishment generating a daily average of 421 Kg. Considering that these SOW are destined to feed animals, the conformity degree in their segregation was determined, through observation and handling ofthe contents of each sample. We verified that only 82 (46%) of the samples were compliant with the segregation criteria established and that this percentage was similar (P=0.189) between the establishments. The high level of deviation demonstrates that the persons working in such environments need continuous training.(AU)

RESUMEN

'If an integrated urban waste management system includes the informal recycling sector (IRS), there is a good chance that more solid waste is recycled' is common sense. However, informal integration brings additional social, environmental, and economic benefits, such as reduction of operational costs and environmental impacts of landfilling. Brazil is a global best practice example in terms of waste picker inclusion, and has received international recognition for its recycling levels. In addition to analysing the results of inclusive recycling approaches, this article evaluates a selection of the best Brazilian inclusive recycling practices and summaries and presents the resulting knowledge. The objective is to identify processes that enable the replication of the inclusion of the informal recycling sector model as part of municipal solid waste management. Qualitative and quantitative data have been collected in 25 Brazilian cities that have contracted waste pickers co-operatives for door-to-door selective collection of recyclables. Field data was collected in action research projects that worked with waste pickers co-operatives between 2006 and 2013. The Brazilian informal recycling sector integration model improves municipal solid waste recycling indicators: it shows an increase in the net tonness recycled, from 140 to 208 t month(-1), at a much lower cost per tonne than conventional selective collection systems. Inclusive systems show costs of US$35 per tonne of recyclables collected, well below the national average of US$195.26. This inclusive model improves the quality of collected material and the efficiency of municipal selective collection. It also diminishes the negative impacts of informal recycling, by reducing child labour, and by improving the conditions of work, occupational health and safety, and uncontrolled pollution. Although treating the Brazilian experience as a blueprint for transfer of experience in every case is unrealistic, the results suggest that this approach to informal sector integration can be considered among the global best practices for informal sector integration. The article closes with recommendations for deploying technology in other urban areas throughout the world.

RESUMEN

Sales of electrical and electronic equipment are increasing dramatically in developing countries. Usually, there are no reliable data about quantities of the waste generated. A new law for solid waste management was enacted in Brazil in 2010, and the infrastructure to treat this waste must be planned, considering the volumes of the different types of electrical and electronic equipment generated. This paper reviews the literature regarding estimation of waste electrical and electronic equipment (WEEE), focusing on developing countries, particularly in Latin America. It briefly describes the current WEEE system in Brazil and presents an updated estimate of generation of WEEE. Considering the limited available data in Brazil, a model for WEEE generation estimation is proposed in which different methods are used for mature and non-mature market products. The results showed that the most important variable is the equipment lifetime, which requires a thorough understanding of consumer behavior to estimate. Since Brazil is a rapidly expanding market, the "boom" in waste generation is still to come. In the near future, better data will provide more reliable estimation of waste generation and a clearer interpretation of the lifetime variable throughout the years.
