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

– Distributions in Figure 33 for new EEE and used EEE are based on the responses of
nine importing trading companies to the survey described in 3.5.1 Structure of surveys.
Therefore:

• For new EEE, the sale distribution of CRT monitors and TVs is not known.
• For used EEE, only the sale distribution of printers is known. It is well known that there
are imports of used computers and household appliances, but this was not reflected
in the study result.
– The average net weight of each tracer import was used according to the baseline
information provided by the Directorate General of Customs (DGA) for year 2020
(Figure 35). Figure 35 displays, as a reference, the unitary weights of imports for 2018
and 2019, as well as those used by UNU in its “E-waste generated tool” used to quantify
the generated WEEE in Costa Rica in 2019 as part of the activities contemplated within
the PREAL project and the development of the Regional Monitoring of Electronic Waste
for Latin America (Wagner et al., 2021). Table 2 shows the maximum and minimum unitary
weights estimated from the 2020 import statistics provided by DGA.
