Yes—our trash can factory can offer a 30-inch opening option for a festival trash can with a wide mouth. A 30-inch mouth is a strong choice for high-traffic event areas because it makes disposal faster, reduces the chance of waste landing outside the bin, and helps staff manage overflow during peak hours. We can adjust the opening specification to match whether your 30-inch requirement refers to the inner diameter, outer diameter, or clear mouth width, so the final design works with your liners, collection bags, and service routine. For festival use, we recommend confirming the bin height, body material, lid style, liner ring, mobility options, and color or branding requirements at the same time. Our factory supports custom production for event waste bins, including wide mouth trash cans, outdoor festival bins, and large-opening collection stations. Please share your target quantity, preferred material, and delivery schedule, and we will confirm the 30-inch opening option, sample availability, MOQ, and lead time for your festival project.
