- Abstract
Abstract This study presents and applies a coherent methodological framework to compare biomass cascading chains, i.e. the subsequent use of biomass for materials, recycling and energy recovery, considering land use, CO2 emission reduction and economic performance. Example cascading chains of short rotation poplar wood are compared with each other on the basis of literature data. Results for these chains vary strongly, namely, from CO2 mitigation benefits of 200 <img src="/fulltext-image.asp?format=htmlnonpaginated&src=R0661665336HQ117_html\10584_2005_Article_5934_TeX2GIFIEq1.gif" border="0" alt="$$\,{}$$" />/Mg CO2 to CO2 mitigation costs of 2200 <img src="/fulltext-image.asp?format=htmlnonpaginated&src=R0661665336HQ117_html\10584_2005_Article_5934_TeX2GIFIEq2.gif" border="0" alt="$$\,{}$$" />/Mg CO2, and from net CO2 emission reductions per hectare of biomass production of 28 Mg CO2/(ha yr) to net CO2 emissions of 8 Mg CO2/(ha yr). Using a present-value approach to determine CO2 emissions and costs affects the performance of long-term cascading chains significantly, i.e. cost and CO2 emission reduction are decreased. In general, cascading has the potential to improve both CO2 emission reduction per hectare and CO2 mitigation costs of biomass usage. However, this strongly depends on the biomass applications combined in the cascading chain. Parameters that significantly influence the results are market prices and gross energy requirements of substituted materials and energy carriers, and the efficiency of biomass production. The method presented in this study is suitable to quantify land use, CO2 emission reduction and economic performance of biomass cascading systems, and highlights the possible impact of time on the attractiveness of specific cascading chains.
