Implementation of ITU-T international standards for sustainable management of waste
electrical and electronic equipment: The path to a circular economy in Costa Rica

The following thirteen coarse fractions were studied:

– Plastic coated electrical cables
– Printed circuit boards
– Aluminium components
– Recyclable plastic
– Galvanized steel components
– Spare parts components (condensers, small batteries, screens, others)
– Computer and cell phone batteries
– Cathode ray tubes
– Glass recovered from liquid crystal screens (LCD)
– Fluorescent lamps contained in EEE
– Non-recyclable plastic
– Other hazardous materials — Plastics with flame retardants (BFR, PBDE, PBB, TBBA)
– Insulating and cooling foams (CFCs)

Fine fractions were grouped into four groups for the analysis, comprising a total of 23 elements,
as shown in Table 4.
