The Importance and Possibilities of the Efficient Use of Natural Fibre-Based Materials

Abstract

The role of CO₂ emissions as a driver of climate change is well known. In addition to emission reduction strategies, CO₂ storage is also important in mitigating global warming. In this context, natural fibre-based materials like wood and paper have become more important due to their ability to store CO₂. Efficient management of this resource is vital due to the limited availability of natural fibres. Good resource management includes optimal utilisation and effective recycling systems, including paper recycling. Lightweight constructions offer an opportunity for the efficient use of raw materials. The Professorship of Wood Technology and Fibre Materials Technology (HFT) conducts research in the field of natural fibre-based lightweight products, more specific on double curved components in sandwich construction with paper honeycomb cores and top layers of fibreboard, in order to develop new applications for this advantageous combination. Paper recycling extends the life cycle of natural fibres significantly. The implementation of paper recycling systems requires a comprehensive understanding of country and region-specific contexts and challenges. Based on the “EcoPaperLoop”-Project, a similar analysis is proposed for Kenya, considering unique challenges posed by water scarcity. Innovative waterless process technologies, such as dry defibration, hold potential as part of the solution.
