The catalog of products and materials containing secondary raw materials was created as an online version of the document for the Czech Standardization Agency. The catalog has two basic sections – an overview of secondary raw materials and recycled products. In order to supplement the overview of the topic, the legislative requirements and related regulations, standards and test procedures for putting recycled products into practice are collected in other sections. An additional glossary of terms contributes to an easier understanding of the catalog issue. An interactive offline version of the catalog in PDF format is also available for download.
