Paper pulp rejects are a waste stream originating from the recycling process of paper. Besides some fibers, these rejects include a large amount of non-recyclable plastics that are separated from the wet paper pulp. These are extremely suitable to be used as alternative energy. However, after its removal from the wet paper pulp, the rejects have a high amount of moisture, leaving waste processing facilities with the challenge to optimise the drying process.
What if the initial dewatering step could be improved? With contents reaching lower moisture levels in the initial step, a lot of energy and money could be saved in further treatments such as drying as well as on transport and gate fee costs.
Pellet production or reuse of paper rejects in general could become much more economical and sustainable while preventing material going to landfill.
Royal Dutch Kusters Engineering aims to provides this solution with its separation technique, the Organic Liquefying Press (OLP). The technology allows the user to separate moisture from solid waste fractions in a smart and energy efficient way. recent tests revealed its potential in dewatering paper pulp rejects, enabling at least 40 to 50% moisture reduction for any input and any level of initial moisture.
