Outdoor trash cans are essential for maintaining clean public spaces, but liquid leakage can create unsanitary conditions and unpleasant odors. To address this issue, designers can implement several effective strategies.

1. Sealed Liners: Using heavy-duty, leak-proof liners inside trash cans can contain liquids and prevent seepage. These liners should be made from durable materials like thick polyethylene.

2. Sloped Bottoms: Designing trash cans with a slightly sloped bottom directs liquids toward a central drainage point, where they can be collected in a removable reservoir or evaporate naturally.

3. Dual Compartments: Separating liquid waste from solid waste with dual compartments reduces the risk of leakage. This design is particularly useful in areas with high volumes of beverage containers.

4. Drainage Holes with Filters: Small drainage holes at the base, paired with filters, allow liquids to escape while trapping solids. The liquid can then be safely absorbed into the ground or collected separately.

5. Elevated Design: Raising the trash can slightly above the ground prevents accumulated liquids from spilling out and makes cleaning easier.

By incorporating these features, outdoor trash cans can effectively minimize liquid leakage, improving hygiene and reducing maintenance efforts.
