Role of Bioeconomy in Circular Economy

Abstract Biomass is a rich energy source worldwide but with a complex supply chain. A complex value of biomass is created, destroyed, and distributed in resource recovery from waste systems. Bioenergy systems mimic the nature and it tends to follow a circular loop in its processes. The use of renewable energy is seen as one of the crucial components of sustainability. Bioeconomic systems are all renewable and follow a cyclic path. The bioeconomy is circular by nature, with carbon being sequestered from the atmosphere by plants, and after its use and reuse, it is cycled in soil carbon or atmospheric carbon again. When the circular economy implements a circular loop in a product’s life cycle, it brings down the concept of end-of-life of a product. The circular economy focuses on the efficient use of finite resources making sure that they are reused or recycled as long as possible. Most of the current circular economic models are not able to eliminate fresh resource addition. Advancements in bioeconomic systems are such that their objective is to eliminate any further addition of fresh resources. Currently, in any of the product’s life cycle, landfill or disposal sites are evident. This chapter provides insights into bioeconomy, challenges, and solution for sustainable bioeconomic pathways. Moreover, it also explains the biomass transformations and impact on climate change.
