However, composting is still seldom considered as

2023/1/1/ · 12.1. Introduction. The exponential rise in human population has resulted in generation of mammoth quantity of waste. According to United Nations report [1] the world population had attained approximately 7.6 billion people in 2017. It is estimated to achieve 8.6 billion in 2030 and will amount to 9.8 billion in 2050 and 11.2 billion by 2100 due to

Compost screening equipment is a kind of fertilizer equipment in fertilizer production line whether organic fertilizer production system or compound fertilizer production process. It is mainly used for separating finished products and returned materials. Therefore, it plays an important role in the process of producing fertilizer.

2023/12/13/ · Hence, an energy-efficient composting technique with minimum environmental impact is needed. This research work aims to analyze the performance of an energy-efficient spouted bed technique for aerobic composting of municipal solid waste for the first time using spouted bed technology with sand as the bed material. Spouted bed

In general, composting poultry can be described as an all-natural, environmentally friendly method of mortality management, which minimizes water and air pollution by retaining nutrients, pathogens, and odors.Given the right conditions, microorganisms break down organic material (poultry mortalities, in this case) and carbon into a useful and valuable
