Innovation of Biodegradable Seedling Cup Made of Calamansi Peel: An Alternative Solution to Decrease Microplastic

This study assessed the feasibility of calamansi peel as primary material in making a seedling cup as an alternative solution to decrease microplastic. The following test have conducted and performed such as appearance test, drop test, water absorption test and nutrient content test to assess the strength, durability, water absorption, and nutrient to helps plant grow. The result of the study revealed the calamansi peel, vinegar, cornstarch, glycerin, and water are the materials needed to manufacture biodegradable seedling cup. It was concluded that seedling cup made in calamansi peel has a beneficial effect on plant growth because it contains nutrients such as nitrogen, phosphorus, and potassium. To launch this eco-friendly activity, it was recommended to work with the government to campaign this initiative and to align with ISO 14001 criteria to check the possible effect in the environment.
