The PlayStation 4 achieved sales of around 117 million units throughout its existence, ranking it among the top-selling consumer electronics of all time. By 2025, Sony was pulling back support for the console, leading to the impending disposal of tens of millions of these devices. The UN’s Global E-waste Monitor 2024 notes that only 22.3 percent of worldwide e-waste is formally recycled. The remainder often ends up in landfills, incinerated, or processed informally overseas.
The lifecycle of the PS4 exemplifies a recurring trend seen with each new console generation. Gaming hardware significantly contributes to the e-waste problem, with the replacement rate of old devices consistently surpassing recycling efforts by manufacturers.
What Goes Into a Console
Modern gaming consoles are composed of metals like gold, copper, lead, nickel, zinc, lithium, cobalt, and cadmium, in addition to processed plastics and specialized circuit components. The extraction and refinement of these materials involve complex global supply chains that can release hazardous chemicals, such as arsenic and mercury, into the environment. Some materials, like tungsten and gold, are sourced from regions associated with conflict and human rights issues.
According to a life-cycle analysis, manufacturing and shipping a single PlayStation 4 unit generates approximately 89 kilograms of CO2 equivalent. This estimate excludes the energy consumed during its years of use, its disposal, and the environmental impact of its accessories like controllers and cables.
When households upgrade their consoles, the environmental footprint is reset as the old device is replaced. Producing a new console involves restarting the entire process of extraction, processing, and shipping.
The Scale of the Disposal Problem
The PS4’s extended lifecycle highlights how slowly consoles leave households. Game File reported that even years after the PS5’s release, about half of Sony’s 118 million monthly active PlayStation users remained on the PS4, as the newer version offered minimal improvements to justify the expense. By 2025, the transition was progressing, with millions of PS4 units moving toward large-scale disposal.
This cycle repeats with each gaming generation. Xbox One consoles are now being phased out, preceded by Nintendo Wii U units. Devices often linger in storage for years before eventually entering the waste stream.
In the U.S., gaming consoles use approximately 34 terawatt-hours of electricity annually, contributing to an estimated 24 million metric tons of carbon emissions. The global e-waste pile in 2022 contained $91 billion worth of recoverable metals, mostly lost to informal processing or dumped in landfills, highlighting a recycling shortfall that gaming hardware exacerbates.
Mid-Generation Upgrades Add to the Problem
In addition to full generational updates, manufacturers have introduced mid-cycle hardware upgrades. The PS4 Pro, Xbox One X, and PlayStation 5 Pro provided enhanced performance for those who already owned earlier models. Unlike full generational shifts, these upgrades don’t technically require the abandonment of older devices. A 2016 analysis pointed out that mid-generation consoles promote the disposal of still-functional hardware, without the platform incompatibility that necessitates generational upgrades for some players.
Trade-in programs offer credits for new devices, yet the compensation for an older console is often much less than the cost of a replacement. The traded-in console typically goes through several resale stages before eventually being discarded.
Where Manufacturer Responsibility Falls Short
Both Sony and Microsoft have released sustainability pledges. Microsoft aims for its Xbox division to be carbon negative by 2030, and newer console models feature energy-efficient standby modes. However, a 2021 analysis by the National Resources Defense Council found that these modes are seldom used, with players often opting for instant-on settings that use more electricity.
Regarding device disposal, no major console manufacturer has implemented a take-back program matching the scale of its sales. There are no large-scale initiatives for collecting PS4s or recovering Xbox Ones. The responsibility for keeping these devices out of landfills largely falls on individual consumers.
Gaming Without Dedicated Hardware
Some gaming occurs without dedicated hardware. Browser-based platforms operate on existing devices like laptops, phones, or tablets. Platforms such as Poki, which reached 100 million monthly players and recorded a billion gameplays in a single month in 2025, offer over 1,500 browser-based titles without installation. This model avoids the environmental impact of manufacturing dedicated gaming devices and the subsequent upgrade cycles.
Although browser gaming represents a small portion of the overall market, most gaming still relies on dedicated consoles and high-performance PCs. However, it illustrates a scenario where gaming does not necessitate a purpose-built device.
What You Can Do
Extending the lifespan of existing hardware can have a greater environmental impact than individual recycling efforts. Here are a few practical steps:
- Keep hardware longer. Using a console for eight years instead of five spreads its manufacturing impact over a longer period. Mid-generation refreshes are optional and not mandatory replacements.
- Find a recycler. Earth911’s recycling search tool accepts “game consoles” as a query and provides local drop-off options by ZIP code. Both Best Buy and Staples offer free recycling for gaming hardware.
- Use certified recyclers. The e-Stewards certification identifies recyclers that adhere to safe handling standards and do not export devices to informal processing sites, where hazardous materials can endanger workers and communities.
- Buy refurbished or previous-generation. A PS4 in 2026 can run most available titles. Purchasing a secondhand one extends the life of an existing device without additional manufacturing costs.
- Donate working hardware. Organizations like PCs for People accept game consoles. Functional devices are more valuable when repurposed than when processed for scrap.
Gaming consoles, like other consumer electronics, face end-of-life challenges. The upgrade cycle outpaces recycling infrastructure. Recognizing this gap can guide more informed decisions about when to upgrade, where to dispose of old devices, and what to purchase next.
