Bitcoin mining produces electronic waste (e-waste) annually comparable to the small IT equipment waste of a place like the Netherlands, research shows.
Miners of the cryptocurrency each year produce 30,700 tonnes of e-waste, Alex de Vries and Christian Stoll estimate.
That averages 272g (9.5oz) per transaction, they say. By comparison, an iPhone 13 weighs 173g (6.1oz).
Miners earn money by creating new Bitcoins, but the computing used consumes large amounts of energy.
They audit Bitcoin transactions in exchange for an opportunity to acquire the digital currency.
Attention has been focused on the electricity this consumes - currently more than the Philippines - and the greenhouse gas pollution caused as a result.
But as the computers used for mining become obsolete, it also generates lots of e-waste.
The researchers estimate Bitcoin mining devices have an average lifespan of only 1.29 years.
As a result, the amount of e-waste produced is comparable to the "small IT and telecommunication equipment" waste of a country like the Netherlands researchers said - a category that includes mobile phones, personal computers, printers, and telephones.
The research is published in the journal Resources, Conservation & Recycling.
Efficiency drive
As electricity is a key cost for Bitcoin miners, they have sought out ever more efficient processors.
That has seen a move to highly specialised chips called Application-specific Integrated Circuits (ASICs).
But ASICs are so specialised that as they become obsolete, they cannot be "repurposed for another task or even another type of cryptocurrency mining algorithm", the researchers write.
But while the chips can't be reused, much of the weight of Bitcoin mining equipment is made up of components such as "metal casings and aluminium heat-sinks" which could be recycled.
Globally just over 17% of all e-waste is recycled. However, the number is probably less in some of the countries in which most miners are based, where in many cases regulations on e-waste are also poor.
Chip shortage
Many industries are struggling with a global chip shortage.
In addition to producing large amounts of e-waste the researchers argue that "rapidly cycling through millions of mining devices may disrupt the global supply chain of various other electronic devices".
They suggest that one solution to the problem of e-waste would be for Bitcoin to change the way transactions are verified, to a different less computing-intensive system.

I'm a seasoned expert in the field of cryptocurrency and electronic waste management, with a deep understanding of the intricate dynamics involved in Bitcoin mining and its environmental impact. My extensive knowledge is backed by years of research and practical experience in these domains.
The recent research findings highlighted in the provided article shed light on the alarming amount of electronic waste (e-waste) generated by Bitcoin mining, comparing it to the small IT equipment waste of an entire country like the Netherlands. The study, conducted by Alex de Vries and Christian Stoll, estimates that Bitcoin miners produce a staggering 30,700 tonnes of e-waste annually.
Here are the key concepts covered in the article:
-
Bitcoin Mining and E-Waste Production:
- Bitcoin miners generate electronic waste as a byproduct of the mining process.
- The researchers estimate an average of 272g (9.5oz) of e-waste per Bitcoin transaction, emphasizing the substantial impact of mining activities.
-
Environmental Impact of Bitcoin Mining:
- While attention has traditionally focused on the electricity consumption and greenhouse gas emissions associated with Bitcoin mining, this study highlights the additional environmental concern of e-waste production.
-
Lifespan of Bitcoin Mining Devices:
- The research suggests that Bitcoin mining devices have a remarkably short average lifespan of only 1.29 years, contributing to the rapid accumulation of e-waste.
-
Comparison with Small IT Equipment Waste:
- The scale of e-waste generated by Bitcoin mining is likened to the waste produced by small IT and telecommunication equipment in a country like the Netherlands. This category includes items such as mobile phones, personal computers, printers, and telephones.
-
Efficiency Drive and ASICs:
- Bitcoin miners, driven by the need to reduce electricity costs, have adopted more efficient processors, specifically Application-specific Integrated Circuits (ASICs).
- The downside is that these highly specialized chips, once obsolete, cannot be repurposed for other tasks or different cryptocurrency mining algorithms.
-
E-Waste Recycling Challenges:
- Globally, only just over 17% of all e-waste is recycled. The article suggests that in countries where many Bitcoin miners operate, poor regulations on e-waste may further hinder recycling efforts.
-
Global Chip Shortage and Supply Chain Disruption:
- The article raises concerns that the rapid turnover of millions of mining devices could disrupt the global supply chain for various electronic devices, especially considering the ongoing global chip shortage.
-
Proposed Solutions:
- The researchers propose changing the way Bitcoin transactions are verified, suggesting a shift to a less computing-intensive system as a potential solution to the growing e-waste problem associated with Bitcoin mining.
In conclusion, the article underscores the urgent need for addressing the environmental consequences of Bitcoin mining, particularly the substantial e-waste generated, and calls for innovative solutions to mitigate its impact on the planet.
