Safety is always a top priority when tackling a blasting job—both for your crew and the surrounding environment. Just as important is minimizing the environmental impact of your project. Since our founding in 1984, ESCA Blast has prioritized both, starting with our original mission to provide Environmentally Sensible Chemical Alternatives.
The Critical Role of Blast Media
Blasting projects can pose environmental challenges, including runoff or residual waste from the materials being removed. The type of blast media you choose plays a major role in reducing this impact. At ESCA Blast, our media options are selected for their cleaning effectiveness as well as their environmental responsibility.
Here are three key factors to consider when choosing eco-friendly blast media:
1. Materials That Do Not Add Environmental Contaminants
Some traditional abrasives can introduce toxic chemicals or heavy metals into the environment. Many of our media options are chemically inert or water-soluble, which helps reduce potential pollutants.
2. Recycled Materials
Opting for media made from recycled content helps reduce waste and environmental strain. Crushed glass, made from post-consumer bottles, and steel grit, made from recycled steel, are excellent examples. These options support circular resource use without sacrificing performance.
3. Reusable Materials
Some media can be used multiple times with proper reclamation systems. Garnet and aluminum oxide, for example, can be recycled several times in enclosed blast systems, offering both cost-efficiency and waste reduction.
Environmentally Friendly Blast Media Options from ESCA Blast
Below is a breakdown of the eco-friendly media we offer, along with the types of applications they’re best suited for.
- Dry Ice: Dry ice blasting is a non-abrasive, chemical-free cleaning method that sublimates on contact, leaving no secondary waste. It’s commonly used in food processing, fire damage restoration, and sensitive electrical work where minimal residue is critical.
- Baking Soda: Sodium bicarbonate (baking soda) is ideal for removing paint, grease, and grime without generating heat or damaging substrates. It’s often used in automotive restoration, graffiti removal, and fire or mold remediation.
- Calcium Carbonate: This naturally occurring, non-toxic media is well-suited for projects where surface preservation is essential, such as historic building restoration or delicate masonry cleaning.
- MaxxStrip (Kieserite): With its neutral pH and water-solubility, MaxxStrip is a preferred option for cleaning pool tiles, fountains, and other water features. It effectively removes calcium and mineral buildup without affecting water chemistry.
- Walnut Shells: Biodegradable and reusable, walnut shells are gentle on delicate surfaces, making them ideal for cleaning aircraft, boat hulls, or wooden structures where you want to avoid surface etching.
- Corn Cob: Corn cob is a plant-based media sourced from agricultural byproducts. It’s great for log homes, wood beams, and smoke damage cleanup, offering a soft-touch solution with minimal dust.
- Glass Bead: Made from virgin glass, this media is ideal for achieving a smooth, satin finish on metal surfaces like stainless steel tanks, food-grade equipment, or medical components. It’s also reusable in pressure or suction cabinets.
- Crushed Glass: Recycled from glass bottles, this angular media is a sharp, clean-cutting abrasive often used in bridge work, marine maintenance, and concrete surface prep. It’s a cost-effective and environmentally responsible choice for outdoor projects.
- GMA PyroBlast: PyroBlast is a naturally occurring mineral well-suited for industrial surface prep, including concrete removal, tank linings, and epoxy coating removal. It’s low-dust and recyclable, often used in bridge repair and infrastructure maintenance.
Engineered Media Options for Low-Dust, Eco-Friendly Cleaning
In addition to natural abrasives, we also offer engineered media that balance performance, safety, and sustainability.
- ProGrit: A low-dust, non-hazardous alternative to coal slag, ProGrit is ideal for paint removal on steel structures, tanks and ships. It meets regulatory standards without the health hazards associated with traditional slags.
- JetMag: A dense, fast-cutting abrasive that generates less waste and requires less product per job. JetMag is used in general industrial blasting, shipyards and large steel structures.
- Garnet: Durable, non-toxic and recyclable, garnet is used in a wide range of blasting applications including pipeline maintenance, power plants and structural steel cleaning. It offers a clean profile and can be reused several times.
- Aluminum Oxide: One of the hardest and most wear-resistant media available, aluminum oxide is ideal for blast cabinets and precision cleaning of engine parts, metal tools, or aerospace components. It’s highly recyclable and long-lasting.
- Steel Shot & Grit: Made from recycled steel, these abrasives are used for heavy-duty cleaning and peening of steel surfaces. They’re commonly found in industrial blast rooms and foundries where media recovery systems are in place.
