Global eWaste sees 21% rise as Africa generates 2.9 metric tones
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.
