The harmful effects of plastic and their product increase the attention of researchers and farmers toward the development and use of biodegradable products. Biodegradable products have several advantages over the plastics, but one of the major concerns is strength. Several researchers found that the strength of the biodegradable product will reduce significantly with the addition of water. To overcome this problem, biodegradable products made from paper waste are mixed with different wet strength agents and surface sizing agents at various proportions to increase their strength against the effect of water. In this study, three types of biodegradable seedling pot, made from waste paper pulp, mixed with wet strength and surface sizing agent in aratio of 0%, 3% and 5%, namely B0, B3 and B5, were tested for their physical, mechanical, germination and degradation properties. In the moisture absorption test, pot with additives showed significantly different properties than pot without additives. The absorption was lower for B0 while the highest for B5. Mechanical properties of pots were tested in dry and wet conditions, where the strength in wet conditions was significantly lower compared to dry conditions. The strength in wet conditions was higher for the pot with additives than the pot without additives; however, no significant difference was found. When comparing the seedlings' total germination percentage and height, no difference was found during the germination and growing test of Broccoli seeds in each pot. In the biodegradation test, all the pots loosed around half of their weight when placed in the soil for a month; however, around 90% of the strength of all the pots was loosed during the same period. Overall, the additives do not show any effect on the germination and growth of broccoli seeds in the seedling tray. However, differences were found among the pots with and without additives for other properties.
