Great question! Finding the right trash bin for a construction site is all about balancing simplicity, durability, and cost. For a very simple and cheap outdoor option, I'd recommend looking at basic, heavy-duty plastic or metal barrels. These are incredibly affordable and can handle the rough environment of a site. You can often find them without lids for maximum ease of tossing in debris, or with a simple, removable lid to help contain lighter waste.
Another excellent choice is a standalone wire mesh basket. They're super simple, allow for airflow, and are very budget-friendly. For a step up in capacity while still keeping things straightforward, consider a large, wheeled trash cart with an open top. It's easy to move around the site as work zones change.
The key is to avoid complex mechanisms. Go for open-top designs or bins with simple, flip-up lids. Look for materials like reinforced polyethylene or galvanized steel that can withstand weather and rough handling without breaking the bank. Remember, on a busy site, the simpler the bin, the more likely it will be used properly by the crew.
