description: M.M. Parascanu, J. Clavell Díaz, M. Rodriguez Mijangos, M. Isasa Sarralde, D. Salle, A. Alonso Galdames, Life cycle assessment of an innovative seabed cleaning platform for marine litter removal in aquatic ecosystems, Environmental Technology & Innovation, Volume 37, 2025, 103971, ISSN 2352-1864, https://doi.org/10.1016/j.eti.2024.103971. (https://www.sciencedirect.com/science/article/pii/S2352186424004474) Abstract: Plastic consumption is projected to rise significantly over the coming decades, especially in developing economies, leading to increased plastic leakage into the environment and the accumulation of waste in ecosystems. Despite the urgent need to address this issue, the environmental implications of marine litter removal technologies have been largely unexplored. This paper addresses this gap by presenting the first comprehensive Life Cycle Assessment (LCA) of the Seabed Cleaning Platform, a novel cable-based underwater robot developed by TECNALIA to remove litter selectively and efficiently from the seabed and lower water column. The Seabed Cleaning Platform introduces significant advancements in marine litter removal by enabling a more efficient and cost-effective process. Its innovative design allows for selective and automated removal of identified debris, ranging from microplastics (>5 mm) to large items. Additionally, the system is designed to operate in a manner that benefits the marine ecosystem, mitigating the environmental impact of traditional clean-up efforts. The LCA provides an in-depth evaluation of the platform's environmental performance throughout its entire life cycle. Results indicate that the use and maintenance phases account for 70.9 % of the total environmental impact. Sensitivity analyses highlight optimization opportunities, such as increasing operational time and waste collection volume to reduce the environmental impact per unit of waste removed and replacing the generator with a smaller, more efficient model to minimize fuel …

description: The objective is supporting the Circular Economy Strategy, the European Strategy for Plastics in a Circular Economy aiming at having all typologies of ML and plastics removed identified, sorted and reused. MAELSTROM will combine innovative processes to recover valuable material for a new life cycle, demonstrating that a sustainable plastics economy can be possible from marine litter and providing a strategic circular marine litter vision for the future. This will be pursued by involving diversified players in the plastic value chain and deploying a mix of ML treating technologies made of physical, chemical solutions. The conversion of solid waste feedstocks into chemical precursors, polymers, materials, etc. shall foster an ecosystem-based bio-industry, innovative manufacturing processes in line with the circular economy approach. The pyrolysis waste-to-energy plant will also produce primary power and 2nd generation fuel. This fuel will be utilized to co-supply MAELSTROM raft energy demands for the removal of seabed/water column ML. The set of ML derived products will be thoroughly analysed for new market prospects within a new industrial life cycle.
