Abstract

   Among organic components of waste, paper influences most significantly on the quantity of methane produced from landfilled wastes. However, there are many different types of paper and the biodegradabilities of them are not identical. The objective of this study is to measure methane generation potential and biodegradability of different types of paper most commonly used in Korea. Corrugated cardboard, newsprint, office paper, coated paper, recycled office paper and disposable diapers were selected and Biochemical Methane Potential (BMP) test was carried out to measure their methane production potentials. The maximum methane production was in a range of 141 and 332 mL-CH4/g-VS and the biodegradability was in a range of 21 and 84% depending on paper species. Both the methane generation potential and the biodegradability of office paper were the highest and those of disposable diapers were the lowest among six types of paper. The holocellulose and lignin contents were considered to cause the differences of methane production potentials among the papers studied
