Composting: Historical Background to Modern Prototypes of the Composting Process
摘要
Composting, which is a biological process that degrades a complex molecular compound into a stable soil amendment, has been practiced for a long time. This process occurs in the presence of microorganisms and oxygen at a suitable range of temperature and transforms organic waste into a valuable amendment for agricultural purposes. The historical evolution of composting has involved an increasing understanding of its role in soil fertility and suitable materials for sustainable agriculture. Ancient civilizations, including the Akkadians, Egyptians, and Chinese, utilized composting with farmyard manure to enhance soil fertility for better crop production. But the use of compost in early American agriculture was reduced due to the use of synthetic fertilizers in the twentieth century to increase the production of crops. However, increasing concerns about soil degradation and the harsh environmental impacts of synthetic fertilizers have led to a renewed interest in composting. Modern composting practices encompass a range of technologies, from traditional methods like windrow composting to more advanced systems such as in-vessel composting and electrical home composters. These technologies have different degrees of control over the composting process, involving several factors such as aeration, temperature, and processing time. The development of efficient composting methods is important for managing increasing volumes of organic waste and mitigating its contribution to landfill methane emissions. Furthermore, compost enhances soil quality, reduces the need for synthetic fertilizers, and supports sustainable agricultural practices. The traditional practices of composting with new innovations and technology can improve the compost quality for better agricultural use.
