Life Cycle Assessment of Wood Pyrolysis for Bio-Oil Production

Author(s): Thomas, H. ;  Bricka, R.

The Department of Chemical Engineering is evaluating a pyrolysis process for the conversion of wood into bio-oil or pyrolysis oil for use in wood treatment. Historically, wood has been treated with a mixture of copper, chromium, and arsenic. Due to the toxic substances and potential leaching into the ground water supply, CCA has been banned from use in the U.S. As older wood is being taken out of service, new methods of preservation are being explored for the wood being put into service. The resulting bio-oil from this pyrolysis process has shown promise as a wood preservative.

Before full scale production can begin a Life Cycle Assessment (LCA) will be performed on the process. LCA is a cradle-to-grave analysis involving the feedstock and materials of construction as well as storage, transportation, and disposal issues. It helps quantify emissions into the air and ground water. The results of the LCA model will be used to determine the economic viability of the process, the energy "break-even point," and the carbon footprint of the process. LCA can also be used to aid in future management and planning for the process.

Responsible Site Design: Implementing Innovative Stormwater Management Strategies

The primary goal of the workshop is to create a dynamic learning experience that examines the role of stormwater management in the built environment. The workshop will focus on integrating ecologically sound water management approaches into site design. After the workshop, attendees will be familiar with the following concepts and technical issues:

  • Knowledge of the stormwater treatment chain
  • Knowledge of the impact of land use codes on stormwater management
  • Application of a design process that mitigates the effects of stormwater on-site
  • Knowledge of the relationship between land use codes and design for innovative stormwater management
