What are the ergonomic considerations for marble outdoor trash can openings?

When designing marble outdoor trash can openings, ergonomic factors are crucial for user comfort and accessibility. Key considerations include the opening height, which should be positioned between 30 to 40 inches from the ground to accommodate most adults without straining. The opening size must be large enough, typically 8 to 12 inches in diameter, to allow easy waste disposal while preventing littering. Additionally, smooth edges and a slight inward slope can reduce the risk of injury and keep debris contained. Materials like polished marble should be used to ensure durability and ease of cleaning, enhancing both functionality and aesthetic appeal in public spaces.
