Mapping and analysing the current waste paper recycling system in Europe for a new fiber-based packaging material

Abstract: Fiber-based packaging has emerged as an alternative to plastic packaging, driven by concerns regarding environmental impact and excessive usage of plastic. In response to market trends favouring circular packaging solutions, Stora Enso is preparing to introduce Papira, an innovative fiber-based cushioning packaging material, in Europe. However, assessing the practical acceptability of new materials within existing recycling systems is crucial alongside laboratory tests that analyse recyclability. Therefore, the purpose of this study is to examine waste paper recycling practices implemented in Europe and identify factors that should be considered when introducing a new product into the European market to provide insights that will help evaluate the positioning of Papira and provide recommendations accordingly. To accomplish this aim, after creating a conceptual framework, a combination of interviews and desk research, including analysis of academic and grey literature sources, was employed to gather valuable insights and develop a comprehensive understanding. The scope of the study focuses on paper and board waste generated by households including eight countries: Belgium, Finland, France, Germany, Luxembourg, Poland, Sweden, and the Netherlands. One of the key findings of this study is the variation observed in the practices employed within the waste paper recycling system. The implementation of the Extended Producer Responsibility system highlights the prominence of both single and multiple Producer Responsibility Organizations, while the household separate collection system involves the collection of waste through different fractions. Consequently, the fractions collected and the designated mills for separated materials play a crucial role in the mechanical sorting stage, alongside the divergence in manufacturing methods employed by mills during the material recycling phase. This underscores critical considerations that arise during the introduction of new fiber-based products. Notably, the composition and fiber content of a product significantly influence its registration within the system, thereby impacting pricing. Additionally, effective labelling is imperative to provide clear guidance to consumers regarding proper disposal methods. Moreover, the suitability of products for mechanical sorting is contingent upon ensuring that sorting technologies align with the waste composition. Lastly, the study identifies four key aspects that hold significance for recycling processes: printing inks, additives, pulping time, and fiber length. In conclusion, Papira, with its high fiber content and biobased additives, has shown promising environmental qualities. However, at the same time, it requires further recognition by the recycling system and consumers, appropriate classification in accordance with the standards, and testing by sorting facilities and recycling mills to meet industry standards and optimise its integration into the recycling system. This study highlights the importance of encompassing the monitoring of actions under the PPWR proposal, the role of consumer communication, and the imperative of maintaining consistent communication among all stakeholders.
