1. Job precariousness: supply chain management in a waste pickers association
Resumo Waste pickers are key players within municipal solid waste management and an important link in the recycling chain. Waste pickers perform their activities in precarious conditions: they work in bad weather; run the risk of traffic accidents; come in contact with insects that transmit disease and suffer from weight overload. These conditions are aggrav

3. SYNTHESIS OF MORPHOLINE-BASED IONIC LIQUIDS FOR EXTRACTIVE DESULFURIZATION OF DIESEL FUEL
Abstract Extractive desulfurization with ionic liquids has attracted significant attention from a growing number of scientists due to the current environmental restrictions on fuel. Protic ionic liquids (PILs) were synthesized via equimolar neutralization of morpholine and formic-based compounds. The obtained PILs were characterized by Fourier transform infr

4. Adding value to polystyrene waste by chemically transforming it into sulfonated polystyrene
ABSTRACT Polystyrene (PS), one of the most used polymers in everyday life, has a low recycling rate due to its inexpensive virgin resin. In order to make polystyrene waste (WPS) recycling advantageous, it is possible to change it chemically, introducing heteroatoms in the polymer chain thus transforming the waste into a material with more added value. In thi

5. Relacionando níveis de maturidade em gestão ambiental e a adoção de práticas de Green Supply Chain Management: convergência teórica e estudo de múltiplos casos
Resumo Embora as temáticas de níveis de maturidade da gestão ambiental empresarial e a adoção de práticas de GSCM estejam se consolidando, elas percorreram, até o momento, um longo caminho desconectadas, embora ambas tenham sua gênese circunscrita à sustentabilidade empresarial. Buscou-se, por meio de múltiplos casos, a caracterização de um padr

6. Reprocessability of PHB in extrusion: ATR-FTIR, tensile tests and thermal studies
Abstract Mechanical recycling of biodegradable plastics has to be encouraged, since the consumption of energy and raw materials can be reduced towards a sustainable development in plastics materials. In this study, the evolution of thermal and mechanical properties, as well as structural changes of poly(hydroxybutyrate) (PHB) up to three extrusion cycles wer

7. Photodegradation of a polypropylene filled with lanthanide complexes
This research aims at studying the photodegradation of a polypropylene formulation filled with lanthanide complexes. These complexes can be used as tracers for the identification of polymer materials in order to facilitate an high speed automatic sorting of plastic wastes for an economically efficient recycling. By paying attention to the evolution of carbon

8. Creating shared value in the recycling chain: processing of the green coconut commercialization waste / Criação de valor compartilhado na cadeia de reciclagem: processamento dos resíduos da comercialização do coco verde
A busca por uma solução comum para os impactos ambientais decorrentes da geração e acúmulo de resíduos sólidos e a condição de exclusão socioeconômica que atinge a uma significativa fatia da população em grandes centros urbanos leva a replicação de um modelo de gestão de resíduos sólidos que tem seu ponto de interseção nas cooperativas de

9. Tomada de decisão em redes logísticas de reciclagem de materiais através da dinâmica de sistemas / Decision making in logistics networks recycling of materials through System Dynamics
The principal aim of this work is to study a model of the closed-loop supply chain, which is based on systemic behavior, through the System Dynamics as a decision making tool. Firstly this model is adapted to the Brazilian issues and then it is applied in a recycling network, in this case it is the municipal solid waste of São Carlos city. The proposal invo

10. Chain extension of poly (ethylene terephthalate) by reactive extrusion with secondary stabilizer
Poly(ethylene tereftalate) (PET) is a polymer highly susceptible to the hydrolytic reactions that occur during applications and mainly in thermomechanical processing. These reactions lead to the decrease of molecular weight of the polymer, limiting the recycling number of the material. The reactive extrusion of the PET in presence of chain extenders is an al

11. Algae of economic importance that accumulate cadmium and lead: a review
Currently, algae and algae products are extensively applied in the pharmaceutical, cosmetic and food industries. Algae are the main organisms that take up and store heavy metals. Therefore, the use of compounds derived from algae by the pharmaceutical industry should be closely monitored for possible contamination. The pollution generated by heavy metals rel
