Food waste composting with selected paper material was conducted in this study to determine the composting efficiency of various paper materials, (regular paper plates, Earthshell-made plates, and a commercial biogradable paper product) to be used in the food service industry, and to understand the effects of the finished compost as a growing medium. Composting experiments were carried out in three piles each with a total weight of approximately 340 kg and a height of 90 cm. Major ingredients in the compost recipe include food waste, dairy manure, and silage. Finished compost was mixed with a sassafras sandy loam in various ratios to grow corn and tomato plants in a greenhouse potting experiment. Composting experiment results indicated that the recipe we developed was very successful in disintegrating all types of paper products. The addition of 25% by weight of the finished compost in the composite growing medium had the least effect on plant germination and growth. Significantly different growth behaviors were observed between corn and tomato plants.
