Products classified as "renewable" are characterized by the fact that their starting materials can be regenerated in less than 100 years. For products with several components, a distinction is made between >80%vol., >50%vol. and >20%vol. share of renewable raw materials.
When selecting renewable products, it is important to note that the environmental balance only represents the effects on the climate and secondary effects such as biodiversity and social factors are only included to a limited extent. When selecting products, various certificates can be consulted that provide information on environmental compatibility, working conditions and economic efficiency (e.g. the FSC and PEFC certificates for wood products).
As a general rule, renewable raw materials are preferable to non-renewable raw materials, although the longevity as well as the treatment of the products must be taken into account.
