Abstract
Biomass utilisation�can benefit from a pre-treatment process because the process disintegrates the link between hemicellulose and lignin, potentially increasing biomethane generation. This work aims to assess available pre-treatments for Napier grass to increase biomethane generation. Important factors such as working volume, temperatures, testing time, and mixture ratios were studied in this work. Furthermore, a biochemical methane potential (BMP) test was conducted to measure the volume of biomethane generated from two Napier grass conditions: ground sun-dried and ground sun-dried with additional oven heating Napier grass. The highest average volume generated by ground sun-dried substrates was 47.67 Nml. On the other hand, about 45.87 Nml methane was generated from the Napier grass with an additional oven heating pre-treatment making the percentage difference in methane volume production between the two conditions of Napier grass is 4%. Based on the result, we found that applying the additional oven heating treatment on Napier grass may seem unnecessary as it only shows a small percentage difference compared to sun-dried Napier grass in terms of methane volume produced. In addition, 1.05�g of volatile solids (VS) of pre-treated samples can produce approximately 50.74 Nml biomethane. � 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
