In the past, when a phone or laptop broke, many people simply bought a new one. This creates a lot of waste.
Now, a growing number of companies want to change that. They sell spare parts, write easy repair guides, and make tools that help people open their devices without fear.
New rules in some countries also help. They ask big companies to sell parts and share repair information. Fixing a device is often cheaper than buying a new one, and it is better for the environment.
