A record 53.6 million metric tonnes (Mt) of electronic waste was
generated worldwide in 2019, up
21 per cent in just five years,
according to the UN’s Global E-waste Monitor 2020, released on Monday.
The new report also predicts global e-waste – discarded products with
a battery or plug – will reach 74 Mt by 2030, almost a doubling of
e-waste in just 16 years. This makes e-waste the world’s fastest-growing
domestic waste stream, fueled mainly by higher consumption rates of
electric and electronic equipment, short life cycles, and few options
for repair.
According to UN, only 17.4 per cent of 2019’s e-waste was collected
and recycled. This means that gold, silver, copper, platinum and other
high-value, recoverable materials conservatively valued at $57 billion —
a sum greater than the gross domestic product of most countries – were
mostly dumped or burned rather than being collected for treatment and
reuse.
According to the report, Asia generated the greatest volume of
e-waste in 2019 — about 24.9 Mt, followed by the Americas (13.1 Mt) and
Europe (12 Mt), while Africa and Oceania generated 2.9 Mt and 0.7 Mt,
respectively.
For perspective, last year’s e-waste weighed substantially more than
all the adults in Europe, or as much as 350 cruise ships the size of the
Queen Mary 2, enough to form a line 125 km long.
E-waste is a health and environmental hazard, containing toxic
additives or hazardous substances such as mercury, which damages the
human brain and / or coordination system.
Other key findings from the Global E-waste Monitor 2020 include that
proper e-waste management can help mitigate global warming. In 2019, an
estimated 98 Mt of CO2-equivalents were released into the atmosphere
from discarded fridges and air-conditioners, contributing roughly 0.3
per cent of global greenhouse gas emissions.
In per capita terms, last year’s discarded e-waste averaged 7.3 kg for every man, woman and child on Earth.
It further revealed that Europe ranked first worldwide in terms of
e-waste generation per capita with 16.2 kg per capita. Oceania came
second (16.1 kg) followed by the Americas (13.3 kg). Asia and Africa
were much lower: 5.6 and 2.5 kg respectively.
According to UN, eWaste remains a health and environmental hazard,
containing toxic additives or hazardous substances such as mercury,
which damages the human brain and / or coordination system. An estimated
50 tonnes of mercury — used in monitors, PCBs and fluorescent and
energy-saving light sources — are contained in undocumented flows of
e-waste annually.
The report informed that eWaste in 2019 was mainly comprised of small
equipment (17.4 Mt), large equipment (13.1 Mt), and temperature
exchange equipment (10.8 Mt). Screens and monitors, lamps, small IT, and
telecommunication equipment represented 6.7 Mt, 4.7 Mt, and 0.9 Mt
respectively.
UN noted that since 2014, the eWaste categories increasing fastest in
total weight terms are: temperature exchange equipment (+7 per cent),
large equipment (+5 per cent), lamps and small equipment (+4 per cent).
According to the report, this trend is driven by the growing
consumption of those products in lower-income countries, where those
products improve the living standards. Small IT and telecommunication
equipment have been growing more slowly, and screens and monitors have
shown a slight decrease (-1 per cent), explained largely by lighter flat
panel displays replacing heavy cathode ray tube (CRT) monitors and
screens.
It however, revealed that since 2014, the number of countries that
have adopted a national e-waste policy, legislation or regulation has
increased from 61 to 78. While a positive trend, this is far from the
target set by the International Telecommunication Union (ITU) which is
to raise the percentage of countries with an eWaste legislation to 50
per cent.
