DOT Spill Cleanup: Nviroclean Use by Scenario

DOT: MASTER THE SPILL CLEANUP GAME

Introduction: Nviroclean is an all-natural, EPA-approved emergency response sorbent made from 100% volcanic rock (amorphous alumina silicate) processed into hollow micro-crystalline structures. It offers exceptional absorption—up to 12x its weight in liquids—while being non-biodegradable for stable, long-term containment. Safe for people, animals, and the environment, it holds NSF food safety certification and excels at encapsulating oils, chemicals, fuels, and bio-waste without leaching contaminants (verified by independent TCLP testing with 99.9% VOC retention). As confirmed in the Safety Data Sheet (SDS), Nviroclean is not classified as hazardous, containing no substances at concentrations that pose health risks.

Storage: Keep Nviroclean in a sealed or closed container to preserve its powdery form and avoid premature moisture absorption.

Application Tips: For fresh spills, first encircle the spill with a ring of Nviroclean (about 1-2 lbs, depending on size) to contain it and prevent spreading. Then, generously pour a layer directly on top (about 1 lb per gallon of liquid). Wait 1 minute for initial encapsulation. Work it into the spill using a broom, brush, or shovel in a circular motion for 1-2 minutes to promote full encapsulation. Allow it to sit for 5-15 minutes (longer for viscous fluids) until the liquid solidifies into a dry, crumbly solid. Sweep or vacuum up the material for reuse or disposal. Wear gloves and eye protection; ventilate if dealing with volatile substances. For large spills (>5 gallons), apply in sections with multiple layers if needed. If the powder is overly dry and causes fly-away during application, spritz lightly with water to settle it without affecting performance. For old or set-in stains only, mix 3 parts Nviroclean with 1 part water into a paste, apply directly, let the water evaporate (30-60 minutes), then sweep up.

Reusability: Nviroclean is reusable up to 5 times for any compatible spills. After use, sweep it up, store dry in a sealed container, and inspect before reusing.

Saturation Indicator: It’s fully saturated when the powder changes color to match the absorbed liquid, signaling the internal voids are filled.

Disposal: Toss saturated Nviroclean in regular trash—it’s safe for standard landfill without special bagging, incineration, or hazardous waste handling, thanks to non-leachable encapsulation.
