>>> Waste paper

It may seem irritating at first glance that envelopes with a viewing window may be thrown in to waste paper. This is possible because the waste paper is broken down into a pulp in the recycling process. The windows can then be easily separated from this waste paper pulp. Of course, it would be exemplary to separate the viewing windows of the envelopes and dispose of them separately in the yellow garbage can.
