Bioconversion of Organic Waste for Circular Bioeconomy

Due to increased urbanisation and industrial operations, municipal solid waste (MSW) has become one of the most serious environmental concerns in today's globe. Annual MSW generation in the world was anticipated to be 2.01 billion tonnes in 2016, and is expected to rise to 3.40 billion tonnes by 2050. The waste sector contributes 5% of worldwide GHG emissions, mostly due to open dumping and disposal in landfills without landfill gas capture technologies. Landfilling accounts for 37% of garbage globally, while open dumping accounts for 33%, posing a serious danger to environmental sustainability as well as a boatload of other societal challenges. Surprisingly, only 80% of worldwide garbage is not recycled, resulting in a loss of resource recovery potential. As a result, biowaste valorization is a compelling strategy that offers a variety of intriguing alternatives to waste disposal/landfilling. Composting, vermicomposting, anaerobic digestion, anaerobic fermentation, gasification, pyrolysis, co-processing, and other valorisation technologies add value to waste. Recovery of value-added products (energy, materials and platform chemicals) contributes to global sustainability, which is based on a low carbon footprint, renewable energy resources, reclamation of degraded land, improved crop yield, waste and pollution reduction, reduced GHG emissions, ecosystem and human health, sustainable agriculture practices, and other factors. Biowaste streams are well-aligned and play a key role in transition of linear economy to a circular bioeconomy, which comprises better resource management and the return of the end waste product into the production cycle to finish the loop and reduce waste. Biowaste may also produce a variety of value-added by-products, such as bioplastics, biopolymers, bioenergy, and biochemicals, through various biorefinery platforms. Adoption and implementation of these biowaste valorization technologies is viewed as crucial for global sustainability.

This Special Issue, “Bioconversion of Organic Waste for a Circular Bioeconomy” aims to present cutting-edge information on various approaches to biowaste valorization, optimization and challenges, value-added products, and their role in environmental as well as socioeconomic sustainability. The following topics are included in the scope of this Special Issue, but are not restricted to them:

  • Biorefineries and their techno-economic feasibility in circular bioeconomy
  • Biowaste-based additives for restoration of marginal and degraded land, and agricultural fields
  • Anaerobic digestion, anaerobic fermentation, gasification, and pyrolysis: Biowaste-to-energy conversion methods, as well as their optimization and economic viability
  • Plant biochemical, physiological, and economic yield properties of biowaste additions
  • Nutrient cycling and Soil microbial ecology with biowaste additives
  • Intersection of biorefineries, circular bioeconomy, and environmental sustainability
  • Biowaste valorisation: Policy, sociological, techno-economic implications
  • Compost, vermicompost, biosolid/sludge, fly-ash, biochar, digestate, and direct land applications of biowaste in agriculture
