1. Halogen Determination in Polymeric Waste of Electrical and Electronic Equipment: Overcoming Limitations in Sample Preparation
Sample preparation of polymers for halogen determination requires special attention because they are difficult to bring into solution and due to the risk of analyte losses when using acid digestion. A method using microwave-induced combustion (MIC) was optimized for accurate determination of halogens in polymeric parts obtained in waste of electrical and ele

2. Selecting chemicals for separation of ABS and HIPS in WEEE by froth flotation
Abstract The feasibility of using common chemicals to separate plastics from waste electrical and electronic equipment (WEEE) by froth flotation is investigated. Plastic waste is one of the WEEE polluters and a separation is necessary to recycle it. The most common plastics in electronic industries are acrylonitrile-butadiene-styrene (ABS) and high impact po

6. Análise de patentes de tecnologias relacionadas a resíduos de equipamentos elétricos e eletrônicos / Analysis of patents for technologies related to waste electrical and electronic equipment
The problem of solid waste has been touted as one of the most serious to date. The increasing scarcity of land for the establishment of new landfills, combined with the existing limitations for the recovery of non-renewable materials, low degree of implementation of new treatment alternatives and recycling, now represent a major challenge. Therefore, conside
