Specific Challenge:Lignin and hemicellulose are mostly treated as low-quality, low-value side streams of lignocellulose fractionation. However, both lignin and hemicellulose are some of the most abundant raw materials — and a potential feedstock — for the bio-based industry. They could play a crucial role in promoting the regional supply and refinement of sustainable biomass feedstock for both existing and new value chains. Several high-value and moderate-value applications of lignin and hemicellulose have already been demonstrated. And both lignin and hemicellulose are potentially already available in large quantities from existing operations. However, it remains a challenge to raise their quality to suitable levels for further processing in an affordable resource-efficient way. To do so, it will be necessary to identify specific, sustainable and economically attractive applications. It will also be necessary to specify the required quality aspects of lignin and hemicellulose to help promote commercialisation.

They could play a crucial role in promoting the regional supply and refinement of sustainable biomass feedstock for both existing and new value chains. Several high-value and moderate-value applications of lignin and hemicellulose have already been demonstrated. And both lignin and hemicellulose are potentially already available in large quantities from existing operations. However, it remains a challenge to raise their quality to suitable levels for further processing in an affordable resource-efficient way. To do so, it will be necessary to identify specific, sustainable and economically attractive applications. It will also be necessary to specify the required quality aspects of lignin and hemicellulose to help promote commercialisation.
For example, lignin has enormous potential as a feedstock for aromatics. However, turning it into a feedstock for bio-aromatic value chains requires chemical reactivity for further processing. Technologies to convert hemicellulose are advancing. Some of these technologies use conversion methods such as fermentation. However, the feedstock must be of adequate quality, and further developments in yeast strains able to transform hemicellulosic sugars are needed. Moreover, new high-volume applications are essential to create a large enough outlet for the large stream of hemicellulose becoming available. Industry is interested in using both lignin and hemicellulose as feedstock for new bio-based value chains.
The specific challenge is to break up lignocellulose into its components to create value for most of all fractions (not only cellulose) in identified applications.
Scope:Develop integral processing technologies to fractionate lignocellulose and deliver components of sufficient quality to be transformed into established or newly emerging high-value applications [1] .
The scope of this topic focuses on the development of an integral fractionation process to produce good-quality cellulose (the main product) and lignin and hemicellulose (the by-products) for established or newly emerging market applications. The scope excludes processes that create ethanol as an end-product.
In addition to the separation of high-quality cellulose, proposals must also include the separation and purification of lignin and hemicellulose to a sufficiently high quality so they can be turned into intermediates or end-products. The developed processes must be designed so that they can be readily scaled up.
Proposals must give convincing evidence of their innovative nature, and they must be complementary to the projects already funded by the BBI JU.
Proposals must always include the proof that the main product cellulose is of high quality (with a market value exceeding EUR 700 per ton) to serve as the basis for a profitable total business case.
Successful proposals will identify market applications for value chains based on lignin and on hemicellulose. These value chains will determine the required quality of the lignin and hemicellulose fractions. Proposals must also achieve this quality in an optimal way with a proper balance between higher-value/lower-volume products and lower-value/higher-volume products. The targeted market sectors can be any, except energy, and proposals should include actors in the related market sector(s).
Proposals should also include options for the consumption of chemicals, their recovery and re-use in the selected processes. They should also describe the recycling potential of the target applications after use.
Proposals should also consider how to turn residual amounts of the feedstock into other added-value applications such as for soil-improvement or bioenergy. The topic excludes, however, energy carriers as the main products, even if used as energy input into the process itself.
Proposals should address all the requirements for RIAs shown in Table 3 of the Introduction of the 2020 Annual Work Plan.
The technology readiness level (TRL) at the end of the project should be 4-5 and not exceeding 5. Proposals should clearly state the starting and end TRLs of the key technology or technologies targeted in the project.
INDICATIVE FUNDING:
It is considered that proposals requesting a contribution of between EUR 2 million and EUR 5 million would be able to address this specific challenge appropriately. However, this does not preclude the submission and selection of proposals requesting other amounts.
[1] The scope of this RIA topic differs from that of the flagship action topic BBI2020.SO1.F1. This topic is about developing a new processing scheme to make use of most of all the fractions of lignocellulose, whereas F1 focuses on lignin only and aims at upscaling proven processes to enable the use of lignin on a commercial scale.
