RESEARCH ARTICLE Effect of spent mushroom substrate as a bulking agent on gaseous emissions and compost quality during pig manure composting Shuyan Li1 & Danyang Li1 & Jijin Li2 & Yangyang Li1 & Guoxue Li1 & Bing Zang3 & Yun Li1 Received: 12 September 2017/Accepted: 31 January 2018 /Published online: 19 February 2018
The single, one-time filling of the composting reactors with the compost mixture showed better performance characteristics over the gradual filling of the reactors. The aeration for 15 min/hour at the rate of 50 L air/min provided sufficient quantity of O 2 for aerobic conditions in the composting mixtures.
2024/1/22/ · The duration required to compost pig manure can vary depending on several factors. With the right conditions and techniques, pig manure can be transformed into nutrient-rich compost within a few months. However, it is important to note that the composting process can take longer under certain circumstances.
