High-Temperature Fluidized Bed Processing of Waste Electrical and Electronic Equipment (WEEE) as a Way to Recover Raw Materials

نویسندگان

چکیده

This paper explores the effectiveness of metal recovery and values gaseous emissions during thermal e-waste processing followed by magnetic separation. The process conversion this kind waste is difficult due to uncertainty operation when compared homogeneous materials. their complex heterogeneous structure. adoption fluidized bed reactor makes feasible, stabilizing it significantly limiting harmful gases. Mobile cellphones were used as raw input material 450 g total mass. During transformation, exhaust gases such as: CO, CO2, NOx, SO2, HCI, HBr, HCN, NH3, phenol, hydrocarbons, HF COCI2 analysed. treatment resulted in 333.6 solids bed. They fragmented into grains smaller than 1 mm 0.5 mm. enrichment was next on greater carried out using a neodymium magnet for particles >1 plate electromagnetic separator (powered three-phase current) together with 1-disc tape-type separator, which <1 Such an approach 81.9% cobalt, 96.6% iron 99.2% neodymium. most efficient method enriching (MS) proved be use separator.

Environmental Information System for Waste Electrical Electronic Equipment (WEEE) Managent: Case Study of Pernambuco (Brazil)

The National Policy on Solid Waste (NPSW) brought a new dimension to waste management in Brazil. According to the requirements of this law, producers, traders, recyclers, importers, distributors, and consumers are each held responsible for waste outcomes. The establishment of reverse logistics systems, also proposed by the law, begins from the management of diffuse interests in support of envir...

High Temperature Erosion- Oxidation Behavior of Nickel- Based Alloys Containing Mo in Fluidized Bed Waste Incineration

High-temperature erosion-oxidation behavior of nickel-based alloys containing 0-7 wt.% Mo in fluidized bed waste incineration conditions was studied. A stream of hot condensed air with a flow rate of 25 L/min caused hot silica sand (700 °C) mixed with 0.5 wt.% of chloride salts to hit the specimens for 250 h. By removing the erosive factor, the high-temperature oxidation behavior of the alloys ...

Waste electrical and electronic equipment (WEEE) recycling for a sustainable resource supply in the electronics industry in China

High consumption of electrical and electronic equipment (EEE) is accompanied with a high yield of waste electrical and electronic equipment (WEEE). Meanwhile, because the different types of resources have their own unique properties, the current content of each type will remain limited in a range of fluctuations. Therefore, WEEE recycling is an obvious choice to meet the resource demands of the...
