<p>The invention relates to envelopes (3) made from waste paper. To this end, the recycled envelopes (3) are folded from pieces of waste paper obtained directly from paper waste so that its preparation does not require the use of any chemical additives, e.g. bleaches, and the addition of water. According to the invention, the waste paper collected and sorted for this purpose is cut into the sections (1) to be processed further, whereby the section shapes (1) and the position of the fold lines (2, 4, 6, 8) are advantageously laid out according to the waste paper sizes used. As the waste paper requires no laborious processing, the production and use of the envelopes (3) of the invention for postal and other purposes results in a particularly favourable eco-balance.</p> |
