The disposal of polypropylene plastic tubes generated by producing seedlings of forest species promotes negative impacts on the environment and human health. These factors have motivated the search for biodegradable and environmentally friendly materials. Thus, the present study aims to evaluate the efficiency and quality of tubes made from particulate waste from cashew nut shells and beeswax in the development of Mimosa caesalpiniifolia Benth. The sustainable tubes were produced using a natural beeswax matrix with proportions of 10, 20, 30, 40, and 50% cashew nut particles. The chemical characterization of the material was performed. The tubes were made in a handmade cardboard mold and P80 wood sandpaper, 35 mm ×: 125 mm (diameter ×: length). The quality of the seedlings was evaluated using the Dickson quality index (DQI). The results showed that the cashew nutshell particles present in their chemical composition have values of 6.83 g kg&minus:1 of nitrogen (N), 0.60 g kg&minus:1 of phosphorus (P), and 1.93 g kg&minus:1 of potassium (K). The quality assessment found that all biodegradable tubes had higher DQI values than polypropylene tubes, emphasizing the treatment with 40% of cashew peel particles, which showed a DQI of 0.14, while the polypropylene tube presented a value of 0.09. Therefore, biodegradable tubes seem a sustainable and efficient alternative for replacing polypropylene tubes in cultivating forest seedlings.
