Background

With their 2050 Roadmap to a low-carbon bio-economy (Unfold the future), CEPI outlined how the forest fibre industry is uniquely placed to contribute to a resource-efficient world. Consumer trends, industrial integration and the impact of policymakers were all discussed. But the fact remained; breakthrough technologies are required in order to be future fit. This is why CEPI launched the Two Team Project. To generate and develop new ideas together with an element of competition. In November 2013 CEPI announced the winning concept of its Two Team Project competition in 2013, aiming to find new breakthrough technologies. The winning concept, Deep Eutectic Solvents (DESs), is now successfully being worked out further in this Europe-wide project.

Objectives

The main objective of the Provides project is to develop a radically new, sustainable and techno-economically feasible pulping technology for wood and agro-based lignocellulose raw materials based on deep eutectic solvents (DES), a new class of natural solvents which have the unique ability to dissolve and thus mildly fractionate lignin, hemicellulose and cellulose at low temperature and atmospheric pressure for further processing into high added value materials and chemicals. In parallel, the development of efficient novel cellulose-dissolving DES and other DESs to process lignocellulose materials, starting with paper for recycling, is aimed at with focus on sustainability in selecting DES chemical components and technical and economic applicability of the solvent system.

 

Savings

The technological breakthrough expected through the development of such new DES pulping technology could reduce process energy intensity by at least 40% and investment costs by 50% compared to traditional chemical pulping technology.

 

How?

Provides will create both fundamental and industry driven technological knowledge based on lab to bench/pilot scale experimentation, through: mapping and selection of most effective DES families; investigating processes and process technology options, including DES regeneration and recycling, in order to define full industrial processes that would isolate high quality cellulose/fibres, lignin and hemicelluloses; providing products for industrial evaluation; establishing technical data to evaluate industrial feasibility and integration; performing life-cycle oriented assessment of environmental and socio-economic performance; assessing impacts in terms of energy and cost reductions as well as new high added value applications Provides could provide to the pulp and paper industry sector.

 

Partners

The Provides project consists of 27 participants, of which 21 large industries active in the pulp and paper industry, 3 universities, 2 research institutes and the coordinator of the project; ISPT. See Partners.
