Cork is the ultimate environmentally friendly product. Even cork that has been used can be given a new life. You may already know of wine cork recycling - where used wine corks are collected and then re-purposed into other cork products including flooring, building material or used in crafting. Another cork product that can be re-purposed is granulated cork (or cork grain). Cork grain is often the bi-product of wine cork production. The grain is then used in many applications including as a stand-in for dirt on movie/theatrical sets. Once the grain has been used for its intended purpose, it can actually be used again. Among other uses, it works and looks great in a garden - offering texture and weed control.
