Abstract Production of renewable energy has a fundamental role to play in mitigating climate change issues. Yet the role of modern bioenergy in decarbonizing the global energy system is not widely recognized. It is unfortunately not receiving the attention it truly deserves. The success story of wind and solar renewable energy increase should be revived by increase in bioenergy, which also can be a type of decentralized local energy production. A good option is to use woody biomass from

short rotation coppice of poplar and willow, combined with phytomanagement, planting trees on brown fields and abandoned agricultural lands that may be contaminated with heavy metals or even organic pollutants. The plants and associated microbes help to remediate spoiled areas. The increased attention to sophisticated thermal treatment of biomass to produce biochar opens up new possibilities for woody biomass and forest residue treatment. They can be converted into energy in the form of volatiles, oils, and the carbonaceous material of biochar.

1 Introduction Until today, most of the world’s energy supply has come from scarce resources like coal oil and gas. In a future low-carbon economy, bioenergy can play a significant role and contribute substantially to the global energy supply [1]. National energy production employs centralized large-scale systems or alternatively decentralized local small units. In circular economy, the smart use of resources becomes the paradigm where agricultural wastes actually become a resource with many opportunities, for producing not only ripe crops but also biomass for bioenergy [2, 3]. However, the role of modern bioenergy in decarbonizing the global energy system is neither widely recognized nor it receives the attention it deserves. IEA report reveals that bioenergy production will have the fastest growth among renewables in the global energy mix over forecasted period of 2018–2023. In 2023, it is estimated that bioenergy remains the largest source of renewable energy owing
