The Economic and Environmental Aspects of Miscanthus × giganteus Phytomanagement Applied to Non-Agricultural Land

Popis výsledku v původním jazyce

Miscanthus x giganteus (M x g) is a promising energy crop in phytotechnology with biomass production. Despite considerable vegetation and harvest under varying climate conditions and across different soils, field-scale studies on utilising M x g remain scarce. Analysing the literature and our own findings, this study intends to highlight the potential of M x g phytotechnology for revitalising non-agricultural lands (NAL), including brownfields, and illustrate the expediency of applying biochar to enhance biomass yield, energy efficiency, and economic feasibility. To validate the feasibility of M x g production on brownfields, two scenarios within the value chain &quot;biomass-biogas-electricity&quot; for green harvest were examined. The assumptions were as follows: (1) a methane yield of 5134 m(3) ha(-1) y(-1), and (2) substrate-specific methane yields of 247 and 283 mL (g oDM)(-1) for the first and subsequent years, respectively. The findings suggest that Scenario 2 is better suited for cultivating M x g on brownfields/NAL, being more sensitive and eliminating inaccuracies and the generalisations of results. From the third year onward, the revenue of M x g production on biochar-amended brownfields showed greater potential for future profitability. Future research should confirm the positive trend in the energy efficiency ratio of M x g phytotechnology on a larger scale, particularly in real brownfield applications.
