Waste paper increasingly contains plastic waste as well. We find this undesirable, but it’s too valuable to simply dispose of. That’s why, in 2018, we commissioned a reject processing plant that turns this waste into fuel pellets. These pellets can replace standard industrial fuels such as natural gas, thereby further reducingCO2 emissions.
The vast majority of our products are made from 100 percent recycled paper; for some varieties, we use pulp from sustainably managed forests in addition to this raw material for technical reasons. The fibers in recycled paper can very often be reused, so that processing and recycling create an environmentally friendly cycle.
The production of paper and cardboard from recycled paper is also energy-intensive, although significantly less so than for products made from virgin fiber. We use state-of-the-art technology to make the most efficient use possible of our current energy source, natural gas. Our in-house power plant can convert up to 92 percent of this energy into electricity and steam. Efficient technology also allows us, for example, to reuse the cooling and waste heat in water and air multiple times, and we also generate our own biogas.
We need water in the production of paper and cardboard primarily to dissolve solid waste paper, clean it, transport the fibers, and form a new paper web from them. In the process, we reuse the same water dozens of times in various cycles. Finally, we treat the water until it is clean enough to be discharged into the North Sea. Through evaporation and precipitation, it then re-enters the cycle.
