I am installing new floors in my home, and I am considering bamboo, cork, linoleum (Marmoleum), and vinyl. I am aware of the environmental advantages of buying bamboo and cork, particularly if bought from an environmentally reputable company. As I understand it, linoleum is made of natural materials and is 100% biodegradable, correct? Vinyl seems to have come a long way. There is a company that states that it's vinyl flooring has recycled content, but they may just be referring to the 100% recycled cork backing. If you wanted to do right by the environment, which of these flooring types, would you choose? Other considerations of mine are pet friendly, waterproof, durability, and easy to maintain. I live in a Mediterranean climate. I am also interested in home resalability. Vinyl doesn't sound like a great selling feature, or has vinyl changed? I am hearing that vinyl is coming back in popularity. Is that true? Thank you for any information you can provide!
