What this dot point is asking
Edexcel wants you to explain the environmental issues that come from using digital devices, across four areas: energy consumption, manufacture, the replacement cycle, and disposal (electronic waste).
Energy consumption
The energy story is not just the device in your hand. Every online service, streaming video, cloud storage, web search, runs on data centres full of servers that draw huge amounts of power day and night, plus cooling to stop them overheating. As more of life moves online, this energy demand grows, which is why efficiency and renewable energy for data centres matter environmentally.
Manufacture
A smartphone contains many different metals and materials, several of them scarce, extracted from the ground in processes that pollute air, water and land and consume energy. This "embodied" environmental cost of manufacture is significant, which is one reason keeping a device longer (rather than replacing it) reduces overall impact.
The replacement cycle
The problem is that a short cycle compounds the other issues: each new device means another round of manufacturing (more materials, more energy, more mining) and the old device becomes waste sooner. Marketing and frequent new releases encourage upgrades that are not always necessary, so the environmental case is for using devices for longer, repairing rather than replacing, and reusing or passing on working devices.
Disposal and e-waste
E-waste is one of the fastest-growing waste streams. Done badly, disposal lets toxic substances leak into soil and water; done well, recycling recovers metals (reducing the need for new mining) and safely handles the harmful materials. Edexcel expects you to know both the danger (toxins in landfill) and the better alternative (recycling and safe disposal).
Bringing the four issues together
The four areas form a life cycle: manufacture (materials and energy), use (electricity and data centres), replacement (a short cycle multiplying the impact) and disposal (e-waste and toxins). A strong "discuss" answer covers several of these, develops each point, and reaches a balanced conclusion, noting that digital technology also brings environmental benefits (less travel, less paper) but that its costs are significant and need managing.
Try this
Q1. State one environmental issue caused by manufacturing digital devices. [1 mark]
- Cue. It uses energy, water and finite raw materials (such as mined rare-earth metals), causing pollution.
Q2. State why e-waste in landfill is harmful. [1 mark]
- Cue. It can contain toxic materials (such as lead and mercury) that damage the environment and health.

Edexcel 20226 marksDiscuss the environmental impact of the widespread use of digital devices such as smartphones and laptops.Show worked answer →
A "Discuss" answer should explore several aspects and reach a balanced view.
Manufacture: making devices uses energy, water and finite raw materials, including rare-earth metals that must be mined, causing pollution and habitat damage.
Energy consumption in use: devices and the data centres that support them consume large amounts of electricity, much still generated from fossil fuels, contributing to carbon emissions.
Replacement cycle: devices are often replaced every few years (driven by new models, fashion and built-in obsolescence) even when still working, which multiplies the manufacturing and disposal impact.
Disposal: discarded devices become electronic waste (e-waste), which can contain toxic materials (such as lead and mercury) that harm the environment if sent to landfill, though recycling can recover materials.
A balanced conclusion notes positives too (digital services can reduce travel and paper), but the manufacture, energy use, short replacement cycle and e-waste are significant negatives that need managing through efficiency, longer use and recycling.
Markers reward exploring several aspects (manufacture, energy, replacement, disposal), developed points, and a balanced judgement. "Discuss" needs breadth and a conclusion, not a single point.
Edexcel 20213 marksExplain why the short replacement cycle of digital devices is an environmental problem.Show worked answer →
Many devices are replaced every few years, often because newer models are released or for fashion, even when the old device still works.
This is a problem because every replacement device requires more raw materials and energy to manufacture (with the associated mining and pollution), and the old device is discarded, adding to electronic waste that can release toxic materials. So a short replacement cycle multiplies both the manufacturing impact and the disposal problem.
Markers reward linking the short cycle to extra manufacturing (materials and energy) and to more e-waste from discarded but still-working devices.
