Is Laser Cleaning Environmentally Safe?

Laser cleaning is one of the cleaner ways to remove rust, paint and coatings. It uses light, not chemicals or abrasive media, so the usual waste streams never get created. It is not zero impact. The removed coating still has to go somewhere, and the machine uses electricity. Here is the full picture.

What laser cleaning avoids

• No chemical strippers. No solvents, acids or caustics to store, handle or dispose of.
• No spent media. Sandblasting leaves piles of used grit mixed with the paint or rust it removed. Laser cleaning has none.
• No runoff. Nothing washes into landscaping, drains or soil, which matters on driveways, stone walls and property near water.
• No water. Useful in Southern Utah, where water is a real constraint.
• Little rework and waste. The laser can be set to remove the coating and leave the base material, so parts are not ground down or pitted and need replacing less often.

What it still leaves behind

The laser turns rust, paint and coatings into vapor and very fine particles. We do not let them drift away:

• A fume extraction system pulls the particles away from the work area as we go and traps them in a filter.
• That used filter, with the captured residue, is the main waste from a job. It is a small, dry, contained amount compared with bags of grit or drums of stripper sludge.
• The laser uses electricity. It draws far less than a large air compressor and blast pot, but it is not free.

Older paint and lead

The coating matters more than the method. Paint on older items can contain lead or other heavy metals, and any method that removes it creates hazardous residue. Tell us how old the item is before we quote. If a coating cannot be processed and contained safely, we will say so and may decline the job. See our FAQ for more.
