Acknowledgements: Funding for this study is provided by the Washington State Department of Ecology with the intention to address the growing demand for information on the design of advanced pyrolysis units. The authors wish to thank Mark Fuchs from the Waste to Resources Program (Washington State Department of Ecology), and David Sjoding from the WSU Energy program for their continuous support and encouragement.. This is the first of a series of reports exploring the use of biomass thermochemical conversion technologies to sequester carbon and to produce fuels and chemicals.

Beyond Waste Objectives: Turning organic waste into resources, such as compost, biofuels, recovery of stable carbon and nutrients and other products promotes economic vitality in growing industries, and protects the environment. This creates robust markets and sustainable jobs in all sectors of the economy, and facilitates closed-loop materials management where by-product from one process becomes feedstock for another with no waste generated.
Disclaimer: It is our objective to investigate previous technologies in order to create extremely clean, nonpolluting thermochemical processes for producing energy, fuels and valuable by-products. The Department of Ecology and Washington State University provide this publication as a review of ancient and existing methods of reduction of cellulosic materials to gases, liquids and char. This does not represent an endorsement of these processes.
The historical development of pyrolysis related industries is one of the most interesting in the annals of industrial chemistry. Very often the by-products of today become the main products of tomorrow.
James Withrow, 1915
Since the chemical industry today can produce by-products obtained from the pyrolysis of wood, with the exception of biochar, more cheaply than the pyrolysis process the main emphasis in the latter is on the production of biochar. For this reason simple carbonization methods, similar to the original biochar piles but in improved form are likely to be more economical than more complicated plants that place emphasis on the isolation and processing of by-products.
Herman F.J. Wenzl, 1970
