When you see the word ECONYL on one of our product pages, it means the product has been made through the ECONYL regeneration process.These carpet tiles are made from 100% regenerated nylon, which is a strong, environmentally friendly fibre. The carpet material is partly made up from fishing nets, toys or whatever is chucked in the ocean. So you're not only getting an aesthetically pleasing, durable carpet plank/tile, but you’re also saving helpless little turtles and other wildlife creatures getting tied up in fishing nets
