Biomass is a vital part of the Brazilian energy matrix, with a possible contribution of co-products from diluted forests. The aim of this work was to judge the energy balance and CO2 potential emission in mechanized biomass harvest operations in pine stands at nine and ten years-old and below dilution, looking to support the employment of co-product biomass from dilution as a renewable energy supply. Dilution was disbursed through cut-to-length harvest methodology, during which giant logs for sawmill and tiny logs for energy were made. Additionally, tops, needles, barks, and branches were thought of as co-products. The balance between consumed energy and emitted CO2 by machines for dilution in relationship to the energy and CO2 in diluted biomass was calculable. Thus, dry matter, energy potential, and CO2 potential emission were evaluated and compared considering dilution stand ages as treatments. Mechanized dilution consumes an oversized energy and produces CO2; however, the energy consumed by machines is below 1 Chronicles of the calculable energy potential in diluted biomass, whereas the CO2 emission is below zero.5% of the biomass.
