The ability to employ waste products, such as vegetable scraps, raw materials for the synthesis of new promising adsorbing is at base circular economy and end concepts. Dextrin-based nanosponges (D_NS), both cyclodextrin (CD) maltodextrin (MD), have shown remarkable adsorption abilities in removal toxic compounds from water wastewater, thus representing a bio-based low-cost solution which establishing itself market. Nevertheless, their environmental safety either aquatic or terrestrial organisms has been overlooked, raising concern terms potential hazards natural ecosystems. Here, (ecosafety) six newly synthesized batches D_NS was determined along with full characterization by means dynamic light scattering (DLS), thermogravimetric analysis (TGA), Fourier transformed infrared spectroscopy attenuated total reflection (FTIR-ATR) transmission electron microscopy (SEM). Ecotoxicity evaluation performed using battery model ecotoxicity assays, microalgae growth inhibition test freshwater Raphidocelis subcapitata marine diatom Dunaliella tertiolecta, regeneration assay cnidarian Hydra vulgaris immobilization brine shrimp Artemia franciscana. Impact on seedling germination plant commercial interest, Cucurbita pepo also investigated. data showed mild low toxicity batches, up 1 mg/mL, following order: R. > H. D. tertiolecta A. franciscana C. pepo. only exception represented one batch (NS-Q+_BDE_(GLU2) resulted highly species, vulgaris. Those criticalities were solved fresh hence attributed single not specific formulation. No effect pumpkin but rather more stimulative observed. To our knowledge this first D_ NS. As we emphasize that current formulations exposure levels range mg/mL do harm species an ecosafe applications.
