  • improving the sustainability of organic waste management practices in the food energy water nexus a comparative review of anaerobic digestion and Composting
    Renewable & Sustainable Energy Reviews, 2018
    Co-Authors: Long Lin
    Abstract:

    Abstract With global population growth, the security of food, energy and water is becoming more challenging. Both anaerobic digestion (AD) and Composting are waste management methods that are plausible approaches to address this challenge by reusing organic waste and generating value-added products. In this paper, recent research on AD and Composting is summarized, and differences in the technical, economic, and environmental aspects of AD and Composting, and their potential to improve the sustainability of waste management, are examined. Recent research on AD has focused on process enhancement and valorization of end products, while Composting research has emphasized ways to shorten Composting period and reduce odor and greenhouse gas (GHG) emissions. Strategies to enhance AD and Composting processes are similar, but the operational parameters that affect microbial activity, including inoculation, aeration, temperature, moisture, C/N ratio, and pH, can differ. AD can be economically more advantageous than Composting, depending on plant scale and valorization of end products, while Composting is more profitable at smaller scales (e.g.

  • Sustainability of using Composting and vermiComposting technologies for organic solid waste biotransformation: Recent overview, greenhouse gases emissions and economic analysis
    Journal of Cleaner Production, 2016
    Co-Authors: Su Lin Lim, Leong Hwee Lee, Ta Yeong Wu
    Abstract:

    Organic solid waste poses a serious threat to the environment as the world struggles to keep up with its rapid generation. Biological waste treatment technologies such as Composting and vermiComposting are widely regarded as a clean and sustainable method to manage organic waste. The focus of this review is to evaluate the feasibility of Composting and vermiComposting as a means to recover nutrients from the organic waste and returning them to the environment. The environmental impact and economic potential of these processes are also discussed. This review shows that Composting and vermiComposting are capable of degrading various types of organic waste, thus enabling them to be adopted widely. The present review also reveals that greenhouse gases are emitted during Composting and vermiComposting processes. However, introductions of intermittent aeration, bulking agents and earthworm abundance may reduce the greenhouse gases emissions. Economic assessments of Composting and vermiComposting technologies show that these technologies are generally viable except in some cases. The differences are due to the wide range in market value for organic fertilizer and differences in cost for the type of composing or vermiComposting system which could affect its economic feasibility. However, if organic fertilizer value increases and carbon offsets are available for nutrient recycling, it will affect the economic feasibility in a positive way.
