Disposable diapers have become a complicated matter due to the risk generation to the environment and human health. This study presents a description of disposable diapers characteristics and the success-proven methods used to handle this waste. In many developing countries where an inadequate waste management system occurs, the handling method selection must consider effectivity, the affordable cost, and the end product quality. Despite the diaper composting has successfully conducted in several previous studies, some issues remain for researchers to address. Thus, it requires an improvement so that the system runs effectively and sustainably. This study aimed to determine the possibility of using Cyanobacteria for enhancing the diapers composting. This study gains insights from previous studies using a literature review method, with the year of publication between 2007 to 2020. The focus of the investigation relates to disposable diapers composting and its optimation by cyanobacteria addition. And so as the future prospecting for application and implication to the environment and human life. Cyanobacteria ability to carry out nitrogen fixation, carbon sequestration, ubiquitous in natural habitat, highly adaptive in a wide range environmental condition, can live in the composting system, perform bioremediation, and its application as quality fertilizer, and potentially degrade plastic polymers, spread the expectation to cyanobacteria which associated with its advantages over other microorganisms to enhance the disposable diapers composting. This study highlights the potential utilization of cyanobacteria as an opportunity for copping disposable diapers pollution. The application of compost resulted expected to provide promising-advantages to the environmental sustainability and agriculture. This paper proposes an overarching review of the feasibility in this regard.

Organic fraction of solid waste, which upon degradation produces foul smell and generates pathogens, if not properly managed. Composting is not a method of waste disposal but it is a method of waste recycling and used for agricultural purposes. An integrated approach of composting methodology was tested for municipal solid waste management. Solid waste first was composted and after 22 days, was further processed by vermicomposting. Samples were routinely taken for analysis of carbon, nitrogen, moisture content, pH and temperature to determine the quality of composting. Decrease in moisture content to 32.1 %, relative decrease in carbon and nitrogen content were also observed. Among the different types of treatment, municipal solid waste + activated sludge integration showed promising results, followed by vermicomposting municipal solid waste + activated sludge combination, compared to the combinations of dried activated sludge, municipal solid waste + activated sludge semisolid and municipal solid waste + sewage water. Thus, windrow composting followed by vermicomposting gave a better result than other methods. Thus this method would serve as a potential alternative for solid waste management.
