2021/1/14/ · The composting experiments were performed for 32 days in 5 L reactors. The results showed that carbon sources could change the nitrogen conversion and improve the compost quality.
2024/2/1/ · Reactor temperature mainly has a significant impact on reaction rate, activation energy, heat generation, and composting efficiency in terms of thermodynamic performance [[60], [61], [62]]. According to the Arrhenius equation, there is an exponential relationship between reaction rate and reactor temperature.
2022/2/1/ · However, the impact of the composting facility and energy input on eco-efficiency is limited. In this study, a LCA approach was conducted to investigate the eco-efficiency of four widely applied composting strategies: static heaps (SH), windrow composting (WC), membrane-covered composting (MC) and reactor composting (RC).
A Compost Heat Exchanger (COHE), hydronically operated, was developed in order to extract and transfer the heat. Energy generated by the compost reactor was calculated, using temperature profiles, captured by the TC-08 data loggers via the K type (PTFE) thermocouples. 11, 449 2 of 14 bioreactors are considered to be an efficient and ...
