Technical Papers

Since the inception of our company in 1976, Jansen employees have authored numerous technical papers and publications pertaining to biomass, chemical recovery, and MSW/RDF boiler topics. These papers were presented at technical conferences, such as TAPPI, ICRC, BLRBAC, INFUB, NAWTEC, NCASI, as well as other venues. Many of them were also published in industry magazines, such as the TAPPI Journal, for example.

An overview of past technical papers by Jansen personnel is presented here for your use. Some of these were co-authored by mill representatives. Included in each overview is an abstract of that technical paper.

We will be happy to send a copy of the full text Technical Paper(s) to any reader who requests it.
