As the production volume of polymers increases, so does the amount of plastic waste. Plastic recycling is one of the concepts to address in this issue. Unfortunately, only a small fraction of plastic waste is recycled. Even with the development of polymers for closed loop recycling that can be in theory reprocessed infinitely the inherent dilemma is that because of collection, cleaning and separation processes the obtained materials simply are not cost competitive with virgin materials. Chemical upcycling, the conversion of polymers to higher valuable products, either polymeric or monomeric, could mitigate this issue. In the following article, we highlight recent examples in this young but fast-growing field. This article is part of the theme issue 'Bio-derived and bioinspired sustainable advanced materials for emerging technologies (part 2)'.

The economical and productive viability of wood plastic in Manaus was developed in this work. Initially, the marketing chain of the tucumã was characterized in order to establish the distribution of the vendors and points of supply of the fruit in the zones of the city. In a second stage, an investigation was carried out into the production of recyclable plastic waste, according to the city zones, aiming to increase the amount of information. In addition, strategies were proposed based on the economic viability study for the implementation of recycling programs according to the best regions of the city. In the third step, a review covering several aspects of the production chain, such as historical evolution, composition, production and application of wood plastic in world terms was presented. In a fourth step, the possibility of producing wood plastic from the mixture of low-density polyethylene (LDPE) and the endocarp of tucumã is reported. Due to the success of the production of wood plastic with LDPE, a composite of wood plastic obtained from polypropylene (PP) and the endocarp of tucumã was obtained. In this work it is possible to observe that with the quantities of woody endocarp and PP discarded in the environment, it would be possible to inject in the local economy around R$ 3.58 million per year to be applied in a range of product possibilities, such as floor plaques and coatings, support of cell phones, picture frames, clipboards, etc. In contrast, R$ 46 million in recyclable plastics are disposed annually in the sanitary landfill of the AM-10 that could be reused commercially.
A viabilidade econômica e produtiva de madeira plástica (wood plastic) em Manaus foi desenvolvida neste trabalho. Inicialmente, a cadeia de comercialização do tucumã foi caracterizada, a fim de estabelecer a distribuição dos vendedores e pontos de fornecimento do fruto nas zonas da cidade. Numa segunda etapa, realizou-se uma investigação da produção de resíduos plásticos recicláveis, de acordo com as zonas da cidade, visando aumentar a quantidade de informações. Além disso, foram propostas estratégias baseadas no estudo de viabilidade econômica para a implantação de programas de reciclagem, segundo as melhores regiões da cidade. Na terceira etapa, uma revisão abordando vários aspectos da cadeia produtiva, como evolução histórica, composição, produção e aplicação da wood plastic em termos mundiais foi apresentada. Numa quarta etapa, a possibilidade de produzir wood plastic a partir da mistura de polietileno de baixa densidade (PEBD) e do endocarpo do tucumã é reportada. Diante do sucesso da produção de wood plastic com PEBD foi obtido e caracterizado compósito de wood plastic obtido a partir da mistura de polipropileno (PP) e do endocarpo do tucumã. Neste trabalho é possível observar que com as quantidades de endocarpo lenhoso e de PP descartados no ambiente, seria possível injetar na economia local cerca de R$ 3,58 milhões anuais para serem aplicados em uma gama de possibilidades de produtos, tais como placas de pisos e revestimentos, suporte de telefones celulares, porta-retratos, pranchetas, etc. Em contrapartida atualmente são descartados anualmente R$ 46 milhões em plásticos recicláveis no aterro sanitário da AM-10 que poderiam ser reaproveitados comercialmente.

L’elaborato è rivolto all’analisi del progetto didattico Dea Minerva, un’iniziativa avviata presso l’Istituto scolastico di Savignano sul Panaro (Comune in provincia di Modena) e sostenuta dall’Amministrazione comunale. Si tratta di un’esperienza a favore dell’ambiente, che si concretizza attraverso l’organizzazione di una raccolta differenziata integrativa di qualità d'imballaggi primari e secondari presso le scuole. Il progetto rientra tra le iniziative di promozione sul territorio dell’economia circolare, un nuovo paradigma a favore di una società più sostenibile, che si sta diffondendo, promosso in particolar modo dall’Unione Europea. L’obiettivo del lavoro svolto è stato quello di ricercare per il progetto didattico un supporto normativo e procedurale definitivo, al fine di aiutarlo a superare le problematiche che attualmente si trova ad affrontare, vista l’incertezza del quadro normativo in cui si inserisce. Per esaminare questo caso, è stato prima inquadrato il contesto normativo europeo e italiano in materia di rifiuti, in particolare rifiuti di imballaggi, e di gestione degli stessi. Successivamente sono state analizzate nel dettaglio, ricercando anche contatti diretti con i soggetti interessati, esperienze simili al Dea Minerva avviate sul territorio italiano, come la raccolta di tappi, di abiti usati o l’uso di compattatori intelligenti, con lo scopo di identificare, a partire da essi, una soluzione per il caso in esame. Alla fine delle ricerche svolte, l’unica soluzione risultata percorribile per l’iniziativa di Savignano, nel quadro normativo italiano, è stata quella di non considerare più il conferimento da parte dei cittadini come raccolta di rifiuti, bensì come donazione di materiale, di cui il soggetto non intende disfarsi, ma decide di tenere da parte e donare volontariamente ad una specifica iniziativa. Per implementare tale soluzione sono richieste diverse modifiche al progetto che, tuttavia, ne consentono un’ulteriore estensione in futuro.

The efficient treatment of waste plastics and pharmaceutical pollutants is of conspicuous environmental, social and economic benefits. Therefore, here it is approached the application of catalysts that can be efficient in mitigating both environmental problems. In this work, four different catalysts were prepared. Three of them were synthesized by co-precipitation of Ni, Al and Fe nitrates with different mass ratios (5%Ni:95%Al, 20%Ni:80%Al and 10%Ni10%Fe80%Al). The fourth catalyst was prepared by wet impregnation of nickel on alumina. Then fresh catalysts were characterized by Fourier Transformed Infrared Spectroscopy and X-ray diffraction to observe crystalline phases. Carbon structures were prepared from low-density polyethylene, used as representative compound of plastic solid waste by Chemical Vapor Deposition over 20% Ni/Al catalyst in a tubular furnace. Scanning Electron Microscopy analyses were performed, identifying the carbon nanostructures with size variation (1 μm to 4 μm). For paracetamol (PCM) removal Catalytic Wet Peroxide Oxidation was assessed with 20%Ni:80%Al, 10%Fe:10%Ni:80% and commercial Al2O3 catalysts. The conversion of paracetamol, hydrogen peroxide and Total Organic Carbon (TOC) were monitorized by High-Performance Liquid Chromatography, UV-Vis spectrophotometer and TOC analyzer, respectively. The iron-containing catalyst showed the highest catalytic activity in the CWPO of PCM satisfactory conversions (complete removal of PCM after 4 h of reaction time under the following operating conditions: Ccat = 2.5 g/L, CPCM,0 = 100 mg/L, pH0 = 3.5, and CH2O2 = 472.4 mg/L).
Um tratamento eficiente de resíduos plásticos e poluentes farmacêuticos traz benefícios ambientais, sociais e econômicos notáveis. Portanto, neste trabalho é proposta a aplicação de catalisadores que possam ser eficientes na mitigação de ambos os problemas ambientais. Neste trabalho preparou-se quatro tipos diferentes de catalisadores. Três deles foram sintetizados por co-precipitação dos nitratos de Ni, Al e Fe, como diferentes proporções de massa (5%Ni:95%Al, 20%Ni:80%Al and 10%Ni10%Fe80%Al). O quarto catalisador foi preparado por impregnação úmida de níquel em alumina. Em seguida, os catalisadores frescos foram caracterizados por Espectroscopia no Infravermelho Transformado por Fourier e difração de raios X, para observar as fases cristalinas. As estruturas de carbono foram preparadas a partir, do polietileno de baixa densidade, usado como composto representativo de resíduos sólidos de plástico, e pelo método de Deposição Química por Vapor realizada em um forno tubular e aplicação do catalisador de 20% Ni/Al. Realizou-se análises de microscopia eletrônica de varredura, para identificar as nanoestruturas de carbono com variação de tamanho (1 μm a 4 μm). Para a remoção do paracetamol (PCM), o método utilizado foi a Oxidação Húmida Catalítica com Peróxido de Hidrogênio, realizado com os catalisadores 20%Ni:80%Al, 10%Fe:10%Ni:80% e alumina comercial. A conversão do paracetamol, peroxido de hidrogênio e carbono orgânico total, foram monitoradas por cromatografia líquida de alta eficiência, espectrofotômetro UV-VIS, e TOC respectivamente. O catalisador contendo ferro mostrou a maior atividade catalítica no processo de CWPO, obtendo conversões satisfatórias de PCM (remoção completa do paracetamol após 4 horas, nas seguintes condições de operação: Ccat = 2.5 g/L, CPCM,0 = 100 mg/L, pH0 = 3.5, and CH2O2 = 472.4 mg/L).
