That's a fantastic question, and it's something every park manager thinks about. The key isn't just having bins, but placing them strategically based on human behavior. First, focus on "points of generation." Bins must be immediately visible at every park entrance and exit—people won't carry trash far. Next, cluster them at high-activity zones: near picnic tables, playgrounds, sports fields, and food concession areas. The rule of thumb is that no one should be more than 30 seconds' walk from a bin.
Visibility is crucial. Use brightly colored bins and place them along natural walkways, not hidden behind bushes. Pair recycling bins right next to trash bins with super clear signage—if they're separate, people often default to the trash bin for everything.
Maintenance is part of placement. An overflowing bin is the biggest litter attractor. Place bins in areas easily accessible for collection trucks on a frequent schedule. Finally, consider the type—lidded bins prevent scavenging by animals, and solar-powered compactors in very busy spots can hold more waste between collections. It's a mix of smart location, constant upkeep, and making the right choice the easy choice for visitors.
