Evaluation of hydrothermal treatment in enhancing rice straw compost stability and maturity

In order to evaluate the hydrothermal treatment (HTT) in enhancing compost stability and maturity of lignocellulosic agricultural residues, a bin-scale (90 L) composting of rice straw with and without “HTT” was performed. The rice straw compost product with “HTT” after 6 weeks of composting can be considered stable and adequate for field application as expressed by pH of 8.4, “EC value” of 2.96 dS m−1, C/N ratio of 12.5, microbial activity of 83%. However, compost may prove phytotoxic if used as growing media for EC sensitive plants. As for rice straw compost product without “HTT”, the high microbial activity (>12.28 mg CO2 g−1 OM d−1) even after 14 weeks of composting suggests that the residue has not stabilized yet and is far away from stability and maturity, although a higher GI (>100%) was observed

Reducing ammonia volatilization during composting of organic waste through addition of hydrothermally treated lignocellulose

Composting of organic wastes rich in nitrogen suffers from the loss of certain amount of nitrogen into atmosphere, notably through ammonia (NH3) volatilization. In this study, the addition of hydrothermally treated lignocellulose (180 °C, 1.0 MPa, 30 min) to composting mixture as a new strategy for reducing NH3 volatilization during the bench-scale composting experiment was tested. The results show that the addition of hydrothermally treated lignocellulose is very effective in reducing NH3 volatilization during composting process. The effect was mainly due to the presence of high amount of simple sugars in treated lignocellulose, which promoted microbial activity to immobilize more inorganic nitrogen during intensive decomposition of organic nitrogenous compounds. As a result, NH3 volatilization reduced from 9.61% in Control to 3.37% in Treated composting mixture. The difference in NH3 volatilization was also reflected by significant difference (p < 0.05) in C/N ratio of the final compost products: with 23.89 in Control and 19.47 in Treated compost
