I have been buying these Oil Only absorbent mats from New Pig for nearly 10 years. We use them in our heavy equipment shop where minor oil spills and drips are common. These mats soak up more oil than you'd think given their size. We also use them, believe it or not, as "floaters" on the top of our wastewater recycling system, in which we use recycled water to pressure wash equipment. We commonly throw two or three of these mats in the wastewater holding pond, and they float on the surface and absorb the oil that sits atop the water before it goes into the recycling system. Works surprisingly well, especially when used with the oil absorbent booms also available thru New Pig. New Pig has been our "go to" source for all containment requirements, safety supplies, signage, etc. The company is prompt in shipping and billing, is eager to help with inquiries and I'm always greeted by a friendly voice at the other end when I do call. I wouldn't think of using any other outlet for my cleanup and prevention needs.
