## 1 Introduction
By reintroducing IAS biomass into production processes and applying circular economy principles, this research not only proposes a novel way to restore ecological balance and reduce waste burning but also demonstrates how these materials can be reintegrated into the production cycle, offering a sustainable solution for biodiversity management and control. This approach has the potential to significantly reduce governmental costs associated with IAS management while introducing forward-thinking, environmentally responsible practices within the industry [15]. _Tradescantia fluminensis_ (Figure 1) is a perennial herbaceous plant belonging to the Commelinaceae family. It is originally from South America, specifically from Argentina and Brazil. Colloquially known as'men's love' or 'cat's ear', this plant has small leaves of 3 cm length 1.5 cm wide and a lengthy rhizatic stem above the ground. The original areasof propagation for this species used to be low light environments with high humidity levels, such as dense forest and riparian zones. This tendency means that riverbank areas in Galicia are highly suitable for the propagation of Tradescantia, leading to adverse consequences for the indigenous vegetation of affected areas, which has been reduced, affecting ecosystem health and biodiversity [14]. This plant exhibits a notable spreading capacity as well as being fast growing and easily adapting to any ecosystem [16]. Its highly adaptable capacity alongside its propagation properties leads to intricate management challenges. Other studies have demonstrated the resistance of Tradescantia to chemical control such as herbicides, as well as its fast recovery capacities [9]. _Tradescantia fluminensis_ was first documented as an invasive alien species in Galicia in 1951. It has been reported that the initial reasons for its introduction into the area were linked to ornamental purposes, livestock feeding, and horticultural lands [9]. Beyond its damage behavior to autochthonousal flora, this species has been studied inside the Commelinaceae family as a great source of renewable bioactive compounds [12]. This has been confirmed with the study in [14], demonstrating the potential of this species within the agro-alimentary and health industries, presenting great antioxidant compounds, anthocyanins, and total phenols [9] making it suitable to be used for its anti-inflammatory, antipyretic, and diuretic attributes and suggesting potential for its incorporation into contemporary medical practices. This study aims to explore the potential of biomass waste from the selected invasive alien species plant _Tradescantia fluminensis_ within the papermaking industry, offering significant opportunities for innovation by reducing waste and challenging the industry's reliance on traditional raw materials. Previous research [16] has demonstrated the viability of _Tradescantia fluminensis_ as a cellulose source for decentralized papermaking systems, successfully integrating both leaves and stems into the pulp blend. Despite its biomass being primarily composed of soft material and links rather than fibers, _Tradescantia_ has proven suitable for papermaking, aligning with the principle that nearly all plant-based materials can serve in this process--a concept supported by recent studies [17; 18; 19; 20]. Building on these findings, this study investigates the potential of mixing _Tradescantia_ biomass with industrially applied eucalyptus pulp to evaluate the applications and benefits of such blends. The goal is to address the growing demand for wood cellulose while reducing the burning of vegetal biomass generated during the cleaning and management of areas affected by _Tradescantia fluminensis_. To achieve this, experiments were conducted to observe how different proportions of _Tradescantia_ biomass and eucalyptus pulp influence paper properties, encompassing the manual preparation of pulp, standardized handsheet development, and physicochemical testing of the samples.
