Royal Cosun is developing an integrated sugar beet pulp (SBP) biorefinery to valorize the refined sugar beet components by producing value added biobased materials and chemicals. This adds considerably to the sugar beet value chain, making it more profitable on long term. Goal of this project is to widen the potential application scope of sugar beet pulp components, by generating generic knowledge and technology in order to make beet pectin based products suitable to be used in home and personal care as well as professional cleaning products.
These products are often already partially biobased, so there is a clear proof that biobased products can be suitable to be used in these applications. The industrial end users in this consortium (Unilever and Diversey) are highly motivated to widen their scope of biobased products and to increase the content of biobased products in their formulations.

Doel van het project

In this project we will develop new components for household and professional detergents, as well as personal care applications based on the unique structures and properties of the sugar beet components. The main focus of the project will be on the development of functional additives (surfactants, sequestering agents) based on beet components and derivatives thereof. Secondly explorative research will be conducted for the development of new functional
additives for household and professional cleaning.

Relatie met missie (Motivatie)

Sugar beet production is an important economic activity in the Netherlands and Western-Europe. After extraction of sucrose (table sugar), significant amounts of sugar beet pulp (SBP) remain. The current major outlets for SBP are animal feed and biogas production. As productivity of crops is key for the transition to a biobased/circular economy, this project will strengthen the value chain for sugar beet. Furthermore, the impact on the society will be an increased opportunity to use more sustainable, safe and environmentally friendly products in markets where consumer acceptance is high.

Geplande acties

Planned results 2019:

MS1 Installation of Project steering committee
MS2 First set of surfactants prepared and characterized
MS3 First set of sequestering agents prepared and characterized
D1-3 Supply 3 types of sugar beet components to the consortium

Achieved results 2019: The consortium was successfully built (MS1), and all partners collaborated in prioritizing the promising candidates for sequestering (MS3). Modelling was used to further funnel the pre-selection. Synthesis methods to obtain the desired sequestering agents were explored, and the most promising routes were identified. The first sets of compounds were successfully prepared, and are ready for evaluation by the partners. For the surfactants (MS2), a selection of the most promising compounds has been made as well. Their synthesis was however given a slightly lower priority in year one, but this will increase in 2020.
Deliverables 1-3; Two of the SBP components were supplied to the consortium and used for the synthesis of the first derivatives. Methods are also in place for the production of the third component, needed for the milestones in 2020.

Planned results 2020: Main focus on identifying the most promising candidates (both surfactant and sequestration agent)

MS4 Results on “type 1” sequestering agent testing
MS5 Results on “type 1” surfactant testing
MS6 Preparation and characterization of “type 2” surfactants
MS7 Preparation and characterization of “type 2” sequestering agents
MS 8 Go/no-go for year 3
D-3 Supply of the third sugar beet component.

Achieved results 2020: In 2019 the focus was to obtain sequestering agents from various components of the SBP. Guided by a pre-selection by modelling and biodegradation predictions various new sequestration agents have been identified. The synthesis work that was started in 2019 was continued in 2020 and the products were evaluated by the foreseen end-users (MS5). Cosun provided the third SBP component that was tested by the other partners for its sequestering properties (MS7). Based on these testing results some particular modifications to this SBP component proved to be interesting and therefore this line of research was further investigated and will be built upon by Cosun (MS7). In 2019 lower priority was given to surfactant products and in this year the research into surfactant derivatives from SBP was intensified. Various surfactants were prepared (MS2) and tested (MS5). Based on these tests potentially interesting modifications were envisioned and these new surfactants were prepared (MS6). MS8, the go/no-go, decision is not yet made this year and will be postponed to March 2021 (see project status/explanation)

Planned results 2021: Main focus is on testing of the identified promising modification to SBP components and evaluating the best candidates in more detail for toxicity, biodegradation and commercial feasibility.
