This document provides Product Category Rules (PCR) for the assessment of the environmental performance of micronized stone from quarry. It aims to be the main way to develop and register EPDs in the International EPD System.

Micronized stone from quarry is a ultra-fine powder, obtained from rock grinding. It is characterized by a selected granulometry lower than 200 µm. It can be used in zootecnic, agri-food, pharmaceutic, painting and building sectors, depending on the characteristics and chemical composition of the stone of origin. For example micronized limestone is mainly used as calcium carbonate additive in agriculture (e.g. fertilizer or chemical for organic management) and feedingstuffs, but it can be used also in pharmaceutic sector, if the purity is high.

The scope of the products does not in general fall under the European standard for core product category rules for construction products, EN 15804, as products are not defined as construction products themselves. Specific products may however fall under the definition of construction products. In such cases this PCR shall not be used. Other PCRs made in accordance with the EN 15804 standard are available at www.environdec.com.

The PCR document may be downloaded in PDF format on the right side of this page. The free registration will also enable you to post comments on the PCR Forum.
