1. Microplastics in Latin America Ecosystems: A Critical Review of the Current Stage and Research Needs
The ubiquity of microplastics ecosystems has gained global attention. In this context, Latin America, which is responsible for 8% of the world’s consumption of plastic material and has a small recycling rate (4.5%), does not have enough data on microplastics contamination in its environmental matrices. This systematic review analyzed 196 studies from 16 te

2. Thermal and catalytic pyrolysis of plastic waste
Abstract The amount of plastic waste is growing every year and with that comes an environmental concern regarding this problem. Pyrolysis as a tertiary recycling process is presented as a solution. Pyrolysis can be thermal or catalytical and can be performed under different experimental conditions. These conditions affect the type and amount of product obtai

3. 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

4. Influence of lubricant oil residual fraction on recycled high density polyethylene properties and plastic packaging reverse logistics proposal
Abstract To recycle post-consumer HDPE contaminated with waste lubricating oils, companies include prior washing and drying in the process. This consumes large amounts of water and energy, generates significant effluent requiring treatment. This study assesses lubricating oil influence on HDPE properties to evaluate the feasibility of its direct mechanical r

5. The Recycling of Sugarcane Fiber/Polypropylene Composites
Mechanical recycling is utilized to reuse waste and obtain other plastic products via the reprocessing of a material in industrial equipment. Natural fiber composites have become more popular in recent years; however, these composites' mechanical behavior remains less well-understood than single polymers’ behavior after recycling. Therefore, the objective

6. Mechanical characterization of sisal fiber-reinforced recycled HDPE composites
The increasing awareness of the environment protection has contributed to concerns regarding alternative procedures for recycling of plastic wastes. Since chemical processes are high cost, energy and often environment harmful, thermo-mechanical techniques of recycling rises as a good alternative. This research deals with mechanical characterization of thermo

7. Reciclagem do lixo de informática: uma oportunidade para a química
Recycling and sustainable development are increasing in importance around the world. In Brazil, the new National Policy on Solid Wastes has prompted discussion on the future of electronic waste (e-waste). Brazil generates the greatest amount of e-waste among Latin American countries. Nevertheless complete recycling, including end processing of e-waste, does

8. Processamento de cartuchos de impressoras de jato de tinta: um exemplo de gestão de produto pós-consumo
This work presents a route for processing spent ink-jet cartridges in an experimental course. The disassembly of the cartridges requires several steps and the recognition of their different components is essential to define the best final destination (recycling, co-processing). The plastic strips were chemically processed so as to recover gold and copper. Th

9. Estudo de processo de reciclagem do composto de polietileno e alumínio proveniente de embalagens cartonadas assépticas através de simulação computacional usando o método dos elementos discretos (DEM) / Study of recycling process for polyethylene / aluminum compound by computer simulation using discrete element method (DEM)
As embalagens cartonadas assépticas para alimentos são comuns em nosso dia-a-dia. Tais embalagens são compostas por três materiais: papel, polietileno de baixa densidade e alumínio. Seu processo de reciclagem se dá em duas etapas sucessivas: a reciclagem do papel e a posterior reciclagem do composto de polietileno e alumínio. Durante a primeira etapa

12. Degradação catalítica de polietileno de alta densidade sobre a zeólita HZSM
In last years it has talked a lot about the environment and the plastic waste produced and discarded. In last decades, the increasing development of research to obtain fuel from plastic material, by catalytic degradation, it has become a very attractive looking, as these tailings are discarded to millions worldwide. These materials take a long time to degrad
