Abstract:
Improving resource use is a pressing research issue because of the huge potential organic waste market. Composting is a recycling technique, treatment to achieve the dual effect of resource recovery and zero waste. Waste composition varies: for example, chicken manure is rich in protein, straw contains wood fibres, fruit and vegetables contain sugar, and food waste contains starch. When considering combining waste streams for composting, it is important to ask if this approach can reduce overall composting costs while achieving a more concentrated result. Chicken manure, in particular, presents a unique challenge. This is due to its high protein content. The lack of precursor sugars for glucosamine condensation in chicken manure results in lower humus content in the final compost than other composting methods. To address this, we conducted experiments to investigate whether adding sugary fruits and vegetables to a chicken manure composting system would improve compost quality. To improve experimental results, we used sucrose and maltose instead of fruit and vegetable waste. Sugars added to chicken manure composting resulted in a significant increase in humic substance (HS) content, with improvements of 9.0% and 17.4%, respectively, compared to the control. Sucrose and maltose have a similar effect on the formation of humic substances. These results demonstrate the feasibility of composting fruit and vegetable waste with chicken manure, providing a theoretical basis for future composting experiments.
摘要:
由于有机废物市场的巨大潜力,改善资源利用是一个紧迫的研究问题。堆肥是一种回收技术,处理,实现资源回收和零浪费的双重效果。废物成分各不相同:例如,鸡粪富含蛋白质,稻草含有木质纤维,水果和蔬菜含有糖,食物垃圾含有淀粉。当考虑将废物流合并进行堆肥时,重要的是要问,这种方法是否可以降低整体堆肥成本,同时实现更集中的结果。鸡粪,特别是,这是一个独特的挑战。这是由于其蛋白质含量高。鸡粪中缺乏用于葡糖胺缩合的前体糖导致最终堆肥中的腐殖质含量低于其他堆肥方法。为了解决这个问题,我们进行了实验,以研究在鸡粪堆肥系统中添加含糖水果和蔬菜是否会提高堆肥质量。为了提高实验结果,我们用蔗糖和麦芽糖代替水果和蔬菜垃圾。添加到鸡粪堆肥中的糖导致腐殖质(HS)含量显着增加,分别提高了9.0%和17.4%,分别,与对照相比。蔗糖和麦芽糖对腐殖质的形成具有相似的作用。这些结果证明了用鸡粪堆肥水果和蔬菜废物的可行性,为今后堆肥试验提供理论依据。
