That's a great question and a common challenge for many cities and businesses looking to manage smoking litter. The best way really depends on the specific bin you're working with, but here's a reliable method that balances durability, safety, and cost.
First, choose a sturdy, commercially-designed public ashtray, typically made of galvanized steel or aluminum with a sand-filled base. Never use a makeshift container. The key is a secure, permanent mount.
For a standard metal post-mounted trash bin, the most effective method is using stainless steel band clamps or U-bolts. Clean the bin's post thoroughly. Position the ashtray's mounting bracket against the post at a convenient height (usually 1-1.2 meters). Wrap the heavy-duty clamps around both the post and the bracket, tightening them firmly with a wrench. Ensure there are no sharp edges exposed.
If attaching to a concrete or brick base, you'll need a hammer drill, concrete anchors, and a compatible bracket. Always check for underground utilities first! For lightweight plastic bins, a specialized adhesive-backed heavy-duty bracket can work, but durability may be less.
Critical considerations: The ashtray must not obstruct access to the trash bin's opening or its servicing. It should be clearly marked with a cigarette symbol. Regular, safe emptying is essential—the sand helps extinguish butts. Always consult and follow local municipal regulations before any public installation.
This simple addition can significantly reduce cigarette litter on sidewalks, making public spaces cleaner and safer for everyone.
