In recent years, competition has increased for determinate resources. There is an urgent need to look for sustainable, non-polluting alternate sources to meet the demands of an ever-increasing population. Sustainable processes and production while using biological material can produce food, fodder, agricultural inputs, fuel etc. with lesser inputs and reduced emission of pollutants. Agricultural waste and food waste are another concern which demands immediate interventions. The Bioeconomy can be a possible way to address these challenges. It includes sustainable production of food, fodder, fiber, fuel, agricultural inputs, and other goods while using renewable resources or different types of waste. This is beneficial to resolve diverse environmental problems such as future bioenergy production technology, societal transformations, pollution management, industrial circular economy, agricultural practices and food securities, climate management etc. Bioeconomy helps to move from a linear economy to a circular economy.
