As the life expectancy of the population increases, the quantity of solid waste produced has also risen. There is therefore a clear need to recycle materials, particularly polymers, and it is very important to reduce the time taken for materials to degrade after they have been discarded. The objective of this study was to develop a composite material from a mixture of waste drug packaging made from HDPE and fiber from the pseudostems of banana plants. A series of experiments were conducted to determine the characteristics of this compound, including tests of its mechanical properties, analyses with scanning electron microscopy and infrared spectroscopy, and tests of biodegradability and ecotoxicity. The infrared analysis showed that the compound was free from chemical groups that could indicate contamination by medications. The biodegradability assessment showed that the HDPERC5 compound took 28% less time to degrade after use was than the postconsumer HDPE (HDPER). The HDPERC5 compound exhibited the best results for possible use for production of domestic utilities, in addition to a shorter degradation time if its final disposal destination were to be a landfill.

“…As described in the scientific literature and by standards organizations, 25,31,32,40 polymer recycling is classified into four categories, which are related to the resource management degree and reduction of processing costs. Polymer recycling operations thus present a hierarchy of preference, with ascending order, which goes from primary to quaternary: Primary recycling or reuse: reprocessing operations of industrial polymeric residues, from the production process itself, to obtaining products with a performance similar to those products made with pristine polymers; Secondary or mechanical recycling: transformation of polymeric residues into a new product with satisfactory performance for its respective application, using mechanical and thermomechanical processing; Tertiary or chemical recycling: processes in which the polymer residues are chemically modified or transformed into small molecules (such as oils or hydrocarbons, in the case of polyolefins), monomers, or oligomers; Quaternary recycling or energy recovery: technological solutions that involve the incineration of polymer waste to generate heat, steam, and electricity. …”

Several researches and technologies on polymer recycling have been driven and justified by the uncontrolled and crescent polymer waste generation in the world. Herein, a critical and concise review on the recent and well-established recycling practices for polymer waste is presented, taking into account not only thermoplastics (or plastics) but also thermosets and elastomers. Moreover, sorting and characterization techniques for polymer waste recycling are detailed and their importance is discussed. An in-depth analysis of the literature indicated that novel and advanced recycling methods for polymeric waste (PW) present difficulties to be applied in the industrial sector, mainly the scientific innovations in the chemical recycling area. In the current scenario, new challenges for the recycling sector are linked to highly contaminated PW from electrical, electronic, and medical products.

“…Essa norma informa que os restos de alimentos gerados por UAN são classificados como não perigosos, embora juntamente com os demais resíduos gerem consequências para o meio ambiente. Assim, a reciclagem destes materiais é, sem dúvida, a melhor alternativa para minimizar problemas ambientais e aumentar o tempo de vida útil dos aterros sanitários (CRUZ et al, 2011;HALL et al, 2009;KINASZ;WERLE, 2008).…”

A elaboração de cardápios saudáveis sob a ótica da produção sustentável é uma tendência mundial entre gestores de serviços de alimentação. O objetivo do estudo foi elaborar uma ferramenta de avaliação para setor de alimentação coletiva, no que diz respeito à produção de refeições e cardápios sustentáveis. Utilizou-se como embasamento científico revisão de literatura nacional e internacional sobre sustentabilidade em serviços de alimentação, e elaborou-se um questionário de verificação. Este questionário foi aplicado em uma UAN institucional e constatou-se conformidade em 70,3% dos itens avaliados. Destacou-se o desenvolvimento de ações relacionadas a geração de resíduos sólidos e a oferta de variedade das escolhas alimentares, embora, não tenha sido realizada auditoria energética e as refeições não apresentarem adequação total quanto à qualidade nutricional. Diante da relevância e escassez de estudos com propostas de avaliação de cardápios sustentáveis que auxiliem gestores, alunos e professores para aplicação de práticas voltadas para a sustentabilidade, sobretudo visando o atendimento legal vigente, o questionário desenvolvido auxiliará estes profissionais para uma gestão contemporânea, facilitando a implantação de ações sustentáveis na produção de refeições. A relevância do tema e escassez de trabalhos que apresentem ferramentas que propiciem adoção de práticas sustentáveis na produção de refeições ressaltam a importância de mais estudos voltados para esta temática. O instrumento desenvolvido nesta pesquisa é de fácil aplicação e contempla as recomendações mundiais da Associação Americana de Nutricionistas, desta forma, almeja-se que seja utilizado por profissionais dos serviços de alimentação visando adoção de ações sustentáveis na produção de refeições. PALAVRAS-CHAVE:Cardápios sustentáveis, unidades de alimentação e nutrição, atitudes. METHODOLOGY OF EVALUATION OF SUSTAINABLE MENU FOR FOOD SERVICES ABSTRACTThe elaboration of healthy menus from sustainable perspective production is a worldwide and imminent trend among professional food service managers. The objective of the study was to elaborate an evaluation tool for collective and commercial food services, in relation to the production of sustainable meals and menus. A review of national and international literature on sustainability in food services was used as a scientific basis. A verification questionnaire was developed. This questionnaire was applied in a collective food service and compliance was verified in 70.3% of the items. It was highlighted the development of actions such as the audit of solid waste and the variety of food choices, although no energy audit was performed and meals did not present adequate nutritional quality. In view of the relevance and scarcity of studies with proposals for evaluation of sustainable menus that assist the activities of managers of food and nutrition units regarding compliance with actions related to sustainability, above all to comply with current legal aspects, the questionnaire developed will have an impact...
