Techno-economic analysis of biorefinery concepts integrated in existing pulp mills

Existing pulp mills have great potential to deliver more products through the integration of biorefinery concepts, and thus become an important part of the future bio-based economy. RISE can help with techno-economic analyzes to show what potentials there are in your particular mill.

Tekno-ekonomics

New, bio-based materials and fuels are often more expensive to produce compared with their fossil-based equivalents, especially if stand-alone plants are considered. The pulp mill offers an excellent platform for integrated biorefinery concepts, especially as utilities such as steam and waste handling are already in place and could be integrated for improved process economy. When considering a new biorefinery concept, a techno-economic evaluation is an excellent help to show possibilities, benefits and technical limits and to further develop the concept in an iterative process. The results can be used as a basis for LCA studies. Full value chains can also be studied, with both cost and carbon footprint evaluated from the forestry outtake to the finished product.

How is it done?

A techno-economic evaluation often starts with a technology review. Mass yields, energy yields and process efficiencies are evaluated and a suitable process layout is constructed, partly by building simple models to determine energy and mass balances. RISE has a good insight in the technical maturity of different technologies and close contact with equipment suppliers which results in accurate estimates of investments, production cost, market volumes and profitability of new biorefinery concepts. RISE can help companies interested in biorefinery with their business development leading to profitable investment decisions.
