“…More specifically, the amount of printed circuit boards (PCBs) is estimated to be increasing at a rate of 5-10% annually (Jaiswal et al, 2015). As a result, every year, twenty to fifty million tons of WEEE are generated in the world (Herat, 2008).…”

Emissions of brominated compounds and polycyclic aromatic hydrocarbons during pyrolysis of E-waste debrominated in subcritical water

2017

Degradation of brominated flame retardants present in printed circuit boards (PCBs) was tested using subcritical water in a high pressure reactor. Debromination experiments were carried out in a batch stirred reactor at three different temperatures (225 ºC, 250 ºC and 275 ºC) keeping a solid to liquid (S/L) ratio of PCB:water=1:5 during 180 min. Results indicated that debromination efficiency was increased with temperature (18.5 to 63.6% of bromine present in the original PCB was removed).Thermal decomposition of the debrominated materials was studied and compared with that of the original PCB. Thermogravimetric analyses were performed at three different heating rates (5, 10 and 20 K min -1 ), studying both the pyrolysis (inert atmosphere) and combustion (in air). Pyrolysis runs of the debrominated materials were also performed in a quartz horizontal laboratory furnace at 850 ºC, in order to study the emission of pollutants. More than 99% of the bromine was emitted in the form of HBr and Br 2 . Emissions of polycyclic aromatic hydrocarbons (PAHs) and bromophenols (BrPhs) decreased with the increase in the treatment temperature; naphthalene (10800 -18300 mg kg -1 original sample) and monobrominated phenols (12.8 -16.9 mg kg -1 original sample) were the most abundant compounds.

“…This also resonates with the limits of ecological citizenship (the idea the humans are part of a larger ecosystem and that the future depends on individuals behaving in a manner that has a positive impact on the natural environment) in relation to responsible waste disposal [78], highlighting the point that appropriate e-waste management is bigger than just individual consumer responsibility. Further, mirroring international e-waste case studies, product obsolescence (planned [66,71] and technological [1,2,43]) was reported as the main contributor to e-waste creation in the district, and 57.2% of Whangarei householders exhibited dissatisfaction with the current state of e-waste management in NZ, with many demanding extended producer responsibilities.…”

“…The considerable volumes of e-waste (Waste Electronic and Electrical Equipment; WEEE) generated internationally [1][2][3][4][5], and the associated environmental and health impacts of this material [1,2,[6][7][8] make this a waste stream of significant concern. Whilst it is recognised that New Zealand's (NZ) waste data is poor and that this inhibits opportunities for better management [9,10], it has been estimated that as much as 97,000 tonnes of e-waste is being disposed of as landfill each year as this Whangarei case study found that 98.2% of generated household e-waste could be ending up in landfill.…”

Is Voluntary Product Stewardship for E-Waste Working in New Zealand? A Whangarei Case Study

2019

New Zealand currently manages its annually-generated 99,000 tonnes of e-waste via voluntary product stewardship schemes. Limited data is available to determine the success of this approach. This lack of data is cited as the logic preventing the declaration of e-waste as a priority product by the Minister for the Environment which would trigger the enforcement of mandatory product stewardship. This case study involved an online survey of 264 Whangarei District householders asking questions about e-waste creation and management, as well as analyses of local services, and local and national policy. It found that only 1.8% of the estimated e-waste created in the district is recycled by municipal services, with the 'cost to recycle' and 'a lack of knowledge' presenting barriers to engagement in these services. The 'lack of ability to repair/the cost to repair' was found to be the most significant driver for e-waste creation. The adoption of mandatory product stewardship for e-waste was recommended to ensure robust and transparent data collection, see recycling services become more accessible, and raise awareness of these services, thus reducing the value-action gap. Mandatory e-waste management would also impact product design to ensure affordable repair-ability, further supporting a circular economy for electronic goods.

“…Esta tendencia, que va en aumento, amenaza la conservación de los ecosistemas y principalmente la salud pública, ya que incluyen elementos nocivos y altamente contaminantes (Song & Li, 2014), como el plomo, el cromo, el mercurio, el cadmio y el arsénico (Jaiswal et al . 2015;Abdollahi et al 2015), los cuales, podrían ser liberados y transportados a los cuerpos de agua, por medio de los lixiviados .…”
