Nuclear Energy in the  Pulp and Paper Industry, Paper360º September/October 2023

In a low-carbon world, there are two sources of carbon for biofuels and chemical feedstocks: biomass and natural sources of carbon dioxide, such as in air and seawater. In an integrated pulp and paper mill, about half the incoming carbon exits as products and the other half as carbon dioxide from kraft recovery and biomass boilers. Most of the plant energy is from these two boilers with some added external natural gas and electricity.

In a recent workshop (see sidebar), my colleagues and I, along with members of the industry, investigated options for co-locating nuclear plants, which can provide the nec-essary heat, electricity, and hydrogen. This will give the flexibility of converting residual biomass into biofuels, chemical feedstocks, and carbon char for sequestration of carbon in soil with recycle of nutrients to the soil. The approach will potentially increase plant revenue and profits.
