Campground Trash, Recycling, and Pack-It-In Pack-It-Out Etiquette

Why burning trash in campfires is illegal

A pervasive misconception among novice campers is that a campfire acts as an incinerator for food waste and packaging. Federal regulations under 36 CFR 2.10 strictly prohibit burning trash, foil, plastic, and food scraps in campground fire rings.

The dangers of burning garbage:

• Incomplete combustion: Campfire embers burn between 600 and 900 degrees Fahrenheit, far below the 1,800 degrees required for municipal waste incineration. Burning plastic plates, styrofoam cups, and coated wrappers releases toxic fumes containing dioxins and heavy metals that campers breathe.
• Unburned food attractants: Charred meat bones, bacon grease, and melted plastic wrappers leave persistent food aromas in the ash bed. Nocturnal scavengers (bears, raccoons, mice) investigate the fire pit hours after you fall asleep, digging through hot embers.
• Aluminum and glass contamination: Aluminum foil, beer bottle caps, and glass bottles do not burn. They shatter into sharp fragments that future campers and children encounter in the ash.

The fire pit exists exclusively for clean, untreated firewood and kindling. All packaging and wrappers belong in designated trash dumpsters.

Operating bear-proof dumpsters correctly

Developed campgrounds in bear habitats provide communal steel dumpsters equipped with mechanical animal-resistant latches. Using these containers properly is critical to camp safety:

• Internal latch mechanisms: Dumpster lids feature a recessed metal housing with a gravity latch or interior release plate. Insert your fingers into the latch opening, press the spring plate upward, and lift the heavy lid with your opposite hand.
• Never prop dumpsters open: Propping a dumpster lid open with a stick or rock because your hands are full defeats the safety mechanism. An open dumpster conditions local bears to associate human camps with effortless food calories, inevitably leading to bears being destroyed.
• No overflow stacking: If a dumpster is completely full, do not stack plastic garbage bags on top of the closed lid or on the ground next to the bin. Ravenous ravens, crows, and coyotes tear plastic bags apart in minutes, scattering waste across the loop road. Carry full bags to the next dumpster cluster or store them inside your vehicle until morning maintenance runs.

Managing kitchen dishwater and greywater

Disposing of food-bearing dishwater requires sanitary discipline:

• Strain out food solids: Pour dishwater through a fine mesh kitchen strainer or paper coffee filter before disposal. Dump the caught food particles into your garbage sack; never wash food chunks onto the soil.
• Dedicated utility sinks: Fully developed campgrounds provide a deep stainless steel utility sink mounted on the exterior of comfort station restrooms. Pour strained dishwater directly down this drain.
• Vault toilet disposal: In campgrounds with vault toilets and no utility sinks, pour strained dishwater down the vault toilet riser.
• Never dump at drinking spigots: Dumping soapy greywater or washing greasy dishes at a communal drinking water faucet violates sanitation regulations and contaminates fresh water supply heads for fellow campers.

Micro-trash sweeps before departure

Before hitching your trailer or rolling up your tent, conduct a systematic micro-trash sweep across your campsite:

• The grid search: Walk the site perimeter in parallel lanes, scanning the ground carefully around the fire ring, picnic table, and parking spur.
• Common micro-trash: Pick up plastic bottle safety rings, bread bag twist-ties, dropped peanut shells, twist-off bottle caps, and cigarette butts.
• Fire pit cleanup: Extinguish your fire completely and remove any stray unburned foil or trash left by previous occupants.

Leaving a campsite cleaner than you found it upholds Leave No Trace ethics and preserves public lands for everyone.
