Electronic waste after a digital TV transition: Material flows and stocks

摘要: Abstract As with every technology, televisions (TV) are prone to replacement due technological evolution of the equipment itself (e.g. CRTs flat panels) or system signal). While former is commonly a gradual change that depends on consumer, latter could be sudden, as it national regulations. When an abrupt happens, can generate abnormal volume at end life. Thus, principal motivation this research estimate amount CRT TV sets will stored by users in 2025, analog switch-off (ASO) Peru. Dynamic Material Flow Analysis (D-MFA) was applied flows and stocks from residential, business public sources between 2005 2017. Because data constraints Business Public (B&P) sector, two scenarios were modeled lower uncertainty estimated number sets. Results show 2.6 5.7 million units, equivalent 41,100 68,200 metric tons leaded glass 4500 8000 lead, placed residential B&P facilities 2017 have become obsolete ASO. Projections for final ASO year, indicate 0.27 5.86 units those places. If planned correctly, resources embedded create urban mining opportunity, but inadequate waste management plan excludes appropriate recycling technologies significant environmental impacts.
