Welcome to the ninth RoadToBio newsletter

Presentation of the latest events results, asking for your opinion on key barriers for bio-based chemicals and a little dig deeper into the dedicated polymer chemicals

Dear Reader,

All throughout summer, we will continue our journey onward.

In this newsletter, we present the results of our latest events, ask for your view on key barriers for bio-based chemicals and dig a little deeper into a group of chemicals that have received special attention in our discussions, the dedicated polymer chemicals.

Enjoy the newsletter!

­ Successful second stakeholder workshop and webinar ­

­ On June 19, the RoadToBio consortium invited stakeholders from the chemical industry, academics, NGOs as well as governmental bodies to a workshop in order to discuss key barriers on bio-based chemicals and products and to validate the business cases that will be included in the roadmap. Discussions were lively, and a lot of input could be gathered from the 20 participants of different stakeholder groups. To round out the process, a webinar was held on July 11 to present initial results and conclusions of the workshop and to give stakeholders who were unable to attend the meeting an opportunity to participate.

­ From “sweet spots” to business cases ­­ ­ ­

­ In the course of the project, a number of “sweet spots” were identified – bio-based chemicals with a high potential to replace fossil-based chemicals by 2030 and to increase the bio-based product share in the chemical industry. Of these sweet spots, 9 were selected for detailed analysis in so-called business cases. The idea was to select different bio-based chemicals and illustrate specific advantages and disadvantages of bio-based production, highlight hurdles that have to be tackled and discuss strategic approaches how to overcome these hurdles. Based on the selected variety, we hope to receive a multitude of insights that allow us to draw conclusions for the diverse field of bio-based chemicals.

The nine business cases selected are:

1,4 Butanediol
Dodecanedioic acid (DDDA)
Lactic acid

Survey about key barriers and hurdles – what is your opinion? ­
­ ­ ­

Key_barriersThe barriers for bio-based chemicals are manifold. During the latest workshop, stakeholders were asked to name key barriers that hinder bio-based production, and then to define actions and name respective actors how these barriers might be tackled. Also, in respect to the time horizon of our roadmap, we asked about the expected time frame required to act on the barrier. Based on the workshop, we have identified three additional barriers:

­ ­ Now it is your turn

We invite you to take an active part in the project. With the provided survey on key barriers for bio-based products you have the opportunity to give us your opinion on which hurdles hold back the bioeconomy. We would be most thankful if you take up the opportunity to participate in the development of the roadmap.
Just fill out the questionnaire and send it back via email until 31st August. ­

New materials with improved functionality represent the largest opportunity for EU bio-based industry ­­ ­ ­

­ The mere fact that a product is bio-based is often not sufficient for a successful market entry. Bio-based materials must have additional characteristics in order to have a real chance to compete with conventional products on the market. It therefore makes sense that dedicated chemicals and polymer-based dedicated chemicals received the most attention during our workshop – these chemicals offer new and improved functionality for end products.

In addition, stakeholders made the following key statements during the workshop:

Production of bulk chemicals is not cost competitive in Europe – The feedstock costs are too high and a continuous and stable availability is not guaranteed
Some of the smart drop-ins have small production volumes or small downstream markets in the EU – this may be a weakness

For all the chemicals studied, there is no straightforward recipe for success. A strength for one product can be a hurdle for a the next. Three selected chemicals exemplary show the strengths that bio-based products have to offer, the reasons why they do not currently dominate the market and how their market share could be increased: ­­ ­ ­

­(Poly)Lactic acid ­

PLA240Lactic acid is a nontoxic and biodegradable polymer with a low price and several marketable applications.

Lactic acid is the cheapest among the biodegradable bio-based polymers but in order to increase its volume, new applications and/or improved recycling characteristics are required. At the current state, however, this potential is not fully exploited and lactic acid is primarily used as a monomer for plastics. In order to become successful and sustainable in the market, ways must be found to recycle this polymer. If this is achieved, market share is predicted to soar.­

­ ­ ­

PHA240PHA is the fastest degradable polymer studied in the project. Therefore it is particularly suitable to be used e.g. as slow releasing fertilizer application or as filler or rheology modifier in home or personal care. The molecule has been known for a long time, but the optimal application is still being researched and investigated. Once one of the promising leads has been developed to a commercial stage, a significant increase in market share can be expected.


PEF240A special case we are considering within the project is PEF. This polymer has the potential to replace the widely used PET as a plastic in the packaging industry. With its high mechanical strength and better barrier properties, it seems possible that less amount of PEF can achieve similar characteristics of PET, leading to cost advantages and light-weight products. Whether the market entry of PEF will be successful depends, among other factors, on potential recycling processes for PEF. The alternative could be the production of bio-PET which is as of yet more expensive than PEF.

­Lessons learned for dedicated chemicals ­­ ­ ­

The results of the workshop have shown that three factors strongly influence the successful introduction of bio-based polymers. ­

RecyclingStrong demand for recyclable bio-based polymers: This requires sorting and separation technology for plastics mixtures and/or the establishment dedicated recycling streams.
cosmeticsSearch for applications other than packaging: biodegradable films for farming, fillers or microbeads for cosmetics, biomedical materials, automotive, electronics and other fields
TableCost competitiveness of bio-based chemicals: Make dedicated chemicals cost competitive by developing technologies that lower production costs and/or switching to cheaper feedstock, e.g. waste streams instead of sugars.

­What you can expect from the next newsletter ­­ ­ ­

After the summer break, in our September’s newsletter we would like to share with you some of the key finding from the development of the business cases for drop-in and smart drop-in bio-based chemicals.

We will present the case studies of bio-based ethylene, methanol, 1,4 butadiene and dodecanedioic acid, and assess the business opportunity that these chemicals could potentially represent for Europe.

Read our next newsletter to learn about barriers and opportunities for drop-in and smart drop-in biobased chemicals. Learn how will these business cases help us develop RoadToBio roadmap.­ ­ ­

Join the network ­

We would like to invite you to join us on the journey to a more bio-based chemical industry. The roadmap should contain clear, realistic goals. Your knowledge and experience is necessary to create a market relevant roadmap with a high impact. Therefore, we will conduct workshops and webinars to involve you as stakeholder.

Your opinion is of utmost importance to us. Through your participation, you get the opportunity to help shape the development process and to find your opinion later in the roadmap.
