ofthe defining characteristics of living organisms is their inherent ability to repair physical damage. A growing trend in biomimicry is the creation of non-living structural materials that also have the capacity to heal themselves when cut, torn or cracked. Self-healing materials which can repair damage without external human intervention could give manufactured goods longer lifetimes and reduc
a product or service’s ecological impact to a minimum.
Therefore the concept has to cover every stage from the first tothe last stage of life cycle ofthe product, that is, from sourcing, manufacturing, packing, transport tothe end ofthe life, since each phase can influence the environment negatively.
