“…Overall, in cyanobacteria composting, all the parameters reached stable condition after days (39), and the organic matter reduced by 7.46% to 10.33% on the 24th day (8). Meanwhile, in this composting, until days 34, the curve showed the shoulders because, during this initial period, Spirulina need a couple of time to adapt to the composting environment before they do the waste degradation rapidly.…”

Disposable diaper waste harms the environment and human health. Composting has gained attention for diaper waste recovery because of cost-effectiveness and wastes conversion into value-added products. Cyanobacteria advantages over other microorganisms to enhance the disposable diapers composting has studied. This research aimed to determine the affection of Spirulina platensis, which is one of the Cyanobacteria species, in the diapers composting. Given the complexity of separating materials, the process involves all parts of disposable diapers. The reactor volume is 30 litres, made of clear plastic to allow Spirulina absorbs light to carry out photosynthesis. A total of 3 kg of disposable diapers composted together with 7 kg of food waste, 250 grams of rice husks as a bulking agent, and pure culture of S. platensis with various density: 1.5, 3.0, 6.0 million of sinusoids. All composting reactors operated in triplicates. The parameters analyzed were organic Carbon, Total Nitrogen, C / N ratio, moisture content, pH, and temperature. After a 6-week composting process, compost with the 6.0 million sinusoids attained the highest degradation rate and the total nitrogen 47% higher than the control. The final compost had good quality and accomplished the limits set in the national regulation. It can be used as a growing medium, as shown in the phytotoxicity tests performed using maize and cayenne pepper. It is a feasible and affordable option for the valorization of disposable diapers, which can apply on a small or home-scale by the community.

“…The specific method is that the farm composts livestock and poultry manure in situ to form the first product, and the third-party company purchases the original product and further processes it to produce organic fertilizer. The composting process not only did a harmless treatment but also reduced the water content in the feces [17] . This mode can also avoid pollution caused by fecal transportation and minimize transportation costs.…”

In recent years, the utilization of manure resources for livestock and poultry farming has attracted a widespread attention, and manure resources utilization models suitable for different regional characteristics have formed gradually. Among them, the production of organic fertilizer from animal manure is a vital utilization method. However, there are still some problems such as high production costs, difficult sales, and the unwillingness of farmers to use organic fertilizers which have affected the breeding cycle and the sustainability of manure treatment in livestock and poultry breeding. This article selected 371 organic fertilizer plants, related farms and farmers in China, focusing on the main links of the entire process of livestock manure-organic fertilizer-farm application, and studied the mode of animal manure collection by organic fertilizer plants. The costs of organic fertilizer production and farmland application were discussed. Moreover, suggestions were made for the promotion and implementation of large-scale organic fertilizers to make good utilization of manure resources in livestock and poultry farming.
