<p>Secret or valuable documents (3) are placed in contact with sheets (2) containing a base material and an oxidizing agent in an amount sufficient for sustaining a glowfront in the sheets (2) and for pyrolyzing the documents (3), whereafter the sheets (2) which, preferably, are pyropapers are ignited. Complete and reliable destruction is achieved by employing sheets (2) which present a rougher surface than the documents (3), for example obtained by embossing channels (4) upon the sheets' surfaces.</p> |
