Abstract
The marker of the degree of release of elements that are difficultly or slowly biodegradable (harmful elements) into the environment for objects consisting of an element (1, 1′, 1″) with a structure which ostensibly modifies the appearance thereof at a rate in accordance with the wear of the fabric of the article (2) for which it is intended, warning the user about it. Said element consists of a button (1) or a label (1′) comprising two layers that are different in appearance, a surface one (11) and a central or lower one (12), the outer one (11) being “able to be worn out” until it disappears at a rate in accordance with the fabric of the article (2). In another variant, the element is a seam (1″) consisting of a thread that is “able to be worn out” until it disappears at the rate in accordance with the deterioration of the fabric of the article (2) for which it is intended.
