Yes—for temporary events, urban trash bins can be chained together, but I would treat it as a small safety and operations plan rather than a quick zip-tie job. Chaining bins to each other can help stop them from tipping over, being dragged out of place, or drifting into walkways when crowds build up. It can also keep a row of bins looking orderly and make waste and recycling stations easier for people to find. The key is to chain them in a way that still lets crews open, empty, clean, and move them without a struggle.
First, check the event permit and local rules. Some cities allow temporary bin clusters, but others have requirements about placement, fire access, accessibility, and waste storage. If the bins sit on a public sidewalk or street, you may need approval from the local authority or the waste hauler. I would not chain bins to a fixed object such as a lamppost, fence, or building fixture unless you have explicit permission, because that can create liability or damage if the setup needs to move quickly.
Use a proper chain, cable, or strap with a quick-release clip, and connect bins at a stable point rather than around the lid or lifting mechanism. Do not chain lids closed: people need to use the bins easily, and crews need to empty them. Keep the chain visible or covered so it does not become a trip hazard, especially at night. Place the bins on level ground, avoid blocking emergency exits, accessible routes, or crowd flow, and leave enough space for servicing. A heavy base or weighted bin is safer than a light empty one in windy conditions.
Plan capacity and servicing before the event starts. Chained bins are harder to move, so make sure the waste team can reach them and swap bags or empty them without unclipping the whole row. Use clear signs for general waste and recycling, and keep the stations tidy so people do not pile rubbish beside them. If the event is large, high-wind, or near roads, ask the waste hauler or event safety officer to review the setup. In short: yes, chaining can work for temporary events, but only with permission, quick-release hardware, good placement, clear access, and a realistic cleaning plan.
