It certainly can be, and remember that for conservancy we repurpose, reduce and reuse as well as recycling. Using discarded cotton clothing to make paper products is an excellent way to recycle and reduce cotton materials headed for the landfill. Using fabric scraps from the garment industry to make paper is a great way to repurpose those leftovers. Using cotton linter to make paper is another excellent example of repurposing something that would otherwise just be a discarded by-product.
