Abstract The rise of paper electronics has been accelerated due to the public push for sustainability. Electronic waste can potentially be avoided if certain materials in electronic components can be substituted for greener alternatives such as paper. Within this report, it is demonstrated that conductive polymers poly(3,4‐ethylenedoxythiophene) (PEDOT), polypyrrole, and polythiophene, can be synthesized by screen printing combined with vapor phase polymerization on paper substrates and further incorporated into functional electronic components. High patterning resolution (100 µm) is achieved for all conductive polymers, with PEDOT showing impressive sheet resistance values. PEDOT is incorporated as conductive circuitry and as the active material in all‐printed electrochromic displays. The conductive polymer circuits allow for functional light emitting diodes, while the electrochromic displays are comparable to commercial displays utilizing PEDOT on plastic substrates.

Long term production data from two independent installations have shown a 4 to 5% increase in hardwood yield for digesters converted to Lo-SolidsTMcooking. The following paper will present and discuss this data along with the results, to date, from a program aimed at identifying the underlying mechanism responsible for increased yield. As part of this program, a methodology for rapid yield determinations based on chip, pulp, and black liquor testing has been developed. Preliminary results for samples collected from one mill have confirmed a 3 to 4% greater pulp yield for the commercial process as compared to a laboratory generated pulp cooked to the same degree of delignification. This paper concludes with a description of planned future work.

The development of atmospheric bubbling fluidized bed (BFB) combustion between 1950 and 1960 led to the workout of a new type offluid-bed process circulating fluidized bed (CFB) combustion.In the Europe, the leadership in the development of CFB technology between
