Study: Top Feedstocks For Pyrolysis Biorefinery

A study into the composition and processability of different biomass feedstocks has found sunflower seed husks and poplar wood slabs to be the most suitable for producing bio-based products via fast pyrolysis conversion. The study was conducted by Capax Biobased Development and BTG Biomass Technology Group as part of the Horizon 2020 project Bio4Products, which is testing the feasibility of a fast pyrolysis based biorefinery concept.

Feedstock composition

A shortlist of 10 feedstocks were studied, focusing on residues from agriculture, food/feed processing and forestry: Hemp shives, Flax shives, Flax pellets, Wheat straw, Olive kernels, Sunflower husks, Poplar wood slabs, Softwood, Hardwood (poplar) and Phytoremediated poplar wood. These feedstocks were selected based on a previous study into biomass availability as well as their suitability for processing and sustainability parameters.

Capax first investigated the physical properties of each feedstock including particle size and moisture content. This was followed by a chemical characterisation, analysing lignin/cellulose/hemi-cellulose ratio, and ash and mineral content.

Effect on pyrolysis products and fractions

To analyse the effect on quality and yield of fast pyrolysis bio-oil – the main product of fast pyrolysis – each of the feedstocks were converted by BTG Biomass Technology Group at their plant in the Netherlands. The highest yield was obtained from the softwood dust, while the worst result came from the wheat straw.

Finally the bio-oils obtained from the different feedstocks were extracted to obtain lignin and sugar fractions. In general, no large differences were found during the extractions. Based on these results and other criteria including ease of handling and sustainability, a ranking was made, with sunflower seed husks and poplar wood slabs coming out on top.

New bio-based products

The lignin and sugar fractions are renewable chemical intermediates that are being used by downstream partners in the Bio4Products project to substitute fossil materials such as phenols and creosote. Hexion is using the pyrolytic lignin to replace fossil phenol in moulding compounds and insulation foams. TransFurans Chemicals are testing how the sugar fraction can be applied in furan based resins, and is working with Foreco to develop a formulation for wood modification.

Partners are reporting positive results, and it is expected that new bio-based products could hit the market soon after the project closes in 2020.

Karel De Winter

Job title: Team leader bioprocessing 

Company: Bio Base Europe Pilot Plant

Tell us about your education and working life up to now.

I pursued a PhD at Ghent University after obtaining my MSc in bioscience engineering. Thanks to the FWO Flanders (a Belgium public research council) I focused on research in the field of applied biotechnology. From this I presented in numerous international conferences, publications, patents and book chapters. Completing my PhD I joined the Bio Base Europe Pilot Plant (BBEPP) as an R&D project engineer where I currently lead a talented team in the field of industrial biotechnology.

What is your main expertise?

During my PhD I studied enzymatic glycosylation processes, enzyme engineering around the recombinant production and purification of proteins. Now at BBEPP I lead projects on biomass pre-treatment, biocatalysis, (gas) fermentation, downstream purification and green chemistry. In this broad area of industrial biotechnology, the team is focused on process development and scale-up, as well as food-grade applications,

What is your work focused on in the Rehap project?

BBEPP is involved in scaling Rehap's developed processes - the extraction of tannins, lignin and carbohydrates from agroforestry waste - as well as the subsequent fermentation of the obtained carbon source to diols, including their isolation. This latter process highlights the broad spectrum of technology BBEPP offers from biomass pre-treatment over fermentation to ATEX downstream processing.

What are the main challenges you face in this work and how are you meeting these challenges?

In the scale-up the most typical are linked to the broad spectrum of technologies applied. When scaling processes from lab to pilot scale, small challenges encountered in the lab such as purification steps, are exacerbated. For example, when extracting bark, a relatively simple process, it floats on water making it difficult to handle and pump. Also, the piloting phase is used to elevate the performance of any process with industrial equipment and so this is the stage where hurdles are typically encountered. A pro-active mind-set, flexibility and hands-on mentality are must-haves in any piloting environment.

How do you see your work helping the project achieve its main objectives?

Process development at lab scale is a high risk yet low capital-intensive operation. An industrial process on the other hand, typically requires a huge capital investment, but the associated risks from a technological point of view after often limited. Between both phases there is a distinct gap in the innovation chain. During piloting the technological risks are still obvious, while also large capital investments are required. Therefore, the use of shared pilot facilities allows this gap to be bridged in the most efficient way: forging equipment, utilities and in particular skilled and experienced workers. Scaling Rehap processes at BBEPP has allowed in-depth techno-economic assessments, as well as the generation of significant amounts of sample materials.

What impact do you see Rehap having in the future?

Some of the processes developed during the project certainly have potential for commercialisation. However, as is the case for many biotechnological driven innovations, policy makers will have to make sure a suitable environment is created to enable true market penetration.

When scaling processes from lab to pilot scale, small challenges encountered in the lab such as purification steps, are exacerbated

What do you enjoy more about working on a project like Rehap?

Working on the establishment of technology to convert agroforestry waste to building materials is both challenging and inspiring. Moreover, Rehap bundles a large variety of motivated people skilled in different domains. We are also blessed with a great coordinator who makes sure the entire project remains on track.

How would you like to see your work develop after the project ends?

I anticipate the Rehap results to contribute to a solid basis for further research and valorisation. For BBEPP, a continued collaboration with partners from the consortium would be beneficial.

Webinar highlights Rehap’s progress in biomass feedstock and valorisation

Responding to the ambitious targets set in the EU’s Europe 2020 strategy of sustainable patterns of consumption and production, Rehap is an EU-funded project facilitating a significant step towards a better use of natural resources by creating novel materials from agricultural and forestry waste, whilst decreasing the use of fossil resources and energy in the process industry.

The project recently held its first webinar, Biomass feedstock and valorisation: An introduction and insight into transforming agroforestry waste into high added-value commercial and sustainable products developed by the REHAP project. The webinar took a close look at the progress being made after two years’ working on biomass feedstock and valorisation.

Aitor Barrio, Rehap project coordinator from TECNALIA led the webinar providing a streamlined detailed overview of the technical objectives of Rehap and how it will demonstrate turning waste into reliable and sustainable applications later to be demonstrated as a prototype structure.

To provide a picture of the processes and regulations in sourcing this agroforestry waste material, Lars Wietschel from the University of Augsburg the state-of-the-art agroforestry residues and the forecasting results of their 2030 waste potentials.

Discussing the optimisation of these biomass waste stream processing and upscaling, Tarja Tamminen, researcher at VTT, explained the novel approach developed to utilise bark by soda/kraft cooking away from the hot water bark extraction traditionally used in the industry.

Andrea Leoncini from RINA Consulting followed by providing a comprehensive look at the project’s market analysis and impact through the life cycle approach. This provided an extremely interesting picture of how Rehap is hoping to sustainability develop and implement these processes for a greener building sector.

During the webinar poll questions were asked to the audience of professionals in companies and institutions such as the pulp and paper industry, biorefineries, forest proprietaries, sawmills and those in the chemical industries or phenolic resin manufacturing for example. Interesting data was revealed on how they saw the progress and wide-scale adoption across Europe in the uptake of bio-based products over their fossil-based equivalents.

These questions, and the results, along with the webinar on demand, can be found here!

This is the first in a series of Rehap webinars. Sign up to the newsletter to be the first to hear about the second edition.

Commission calls for bioeconomy strategies to be expanded and implemented

Under the future Common Agricultural Policy (CAP), the European Commission will not approve the national strategic plan of a member state that does not include the promotion of the bioeconomy in agriculture, the EU’s farming Commissioner Phil Hogan said on Thursday (25 April).

“The bioeconomy is a very important subject that requires EU-wide action and it is now stating explicitly as part of the 9 EU objectives” of the reformed CAP, Hogan said.

The EU Commissioner for agriculture and rural development was answering a question from EURACTIV.com at the conference Our Forest, Our Future in Brussels last Friday (26 April).

Through national strategic plans laid down in the proposed CAP, all member states will outline how they want to meet these 9 EU-wide objectives, including the promotion of the bioeconomy, using the CAP tools.

Hogan pointed out that EU countries are required to submit proposals on how to expand the bioeconomy’s role in agriculture and in all bio-based industries.

According to the EU’s agriculture boss, EU member states will have more freedom under the Commission’s proposal for the future CAP. This freedom will allow them to focus on their bioeconomies and help them meet the higher ambitions of the future policy on the environment and climate change.

“A sustainable bioeconomy is also hugely important for reducing emissions in the EU,” said Hogan, mentioning bioenergy’s contribution to help meeting renewable energy targets for 2020 and 2030, but also to substitute fossil-based materials in sectors like construction, plastics or textiles.

EU and national strategies

The Commission’s bioeconomy strategy was initially conceived seven years ago as a way to encourage Europe to be less dependent on petroleum. The updated strategy presented last October expanded its action plan to develop a sustainable and circular bioeconomy from mainly biofuels to any kind of bio-based industry.

Now the strategy looks more at the circular economy as well as sustainability. The three goals of the strategy, as stated by the Commission, are to strengthen and scale up the bio-based sectors, unlock investments and markets, deploy local bioeconomies rapidly across the whole of Europe and understand the ecological boundaries of the bioeconomy.

The Commission’s action plan also promotes the uptake of national bioeconomy strategies, setting up tools such as the European bioeconomy policy support facility, as well as a European Bioeconomy forum, in order to help EU countries develop their own strategy.

“We need a bioeconomy strategy that can be implemented in every member state,” Hogan said.

Currently, only Germany, France, Spain, Ireland, Italy, Latvia, Finland and Malta have dedicated national bioeconomy strategies at the national level. Six EU countries have strategies under development while the remaining 13 have other policy initiatives or related strategies at a national level.

Additional income for farmers

“For the past 4 years at the EU level, I have put the bioeconomy centrally in the agricultural policy discussions of the future,” said Hogan.

According to Hogan, the European Parliament agrees that the bioeconomy can be a win-win for farmers and cooperatives when it comes to creating jobs in rural areas and  providing a new source of income for farmers.

However, the three reports that together form the entire CAP structure were approved only by the agriculture committee of the European Parliament, without reaching the plenary stage.

It means that it will be up to the Conference of Presidents of the next Parliament, after the EU elections in May, to decide whether to forward the draft report directly to the plenary or ask the next agriculture committee to start from scratch instead.

“We have tried our best to get member states and farmers focused on this for the future,” Hogan said. “And now, for the first time, I think we are succeeding.”

Hogan hopes member states will make their own initiatives and that the discussions with the Romanian presidency will be successful and help farmers and producers see the potential of the bioeconomy.

April partner meeting round-up

The most recent partner meeting was hosted by RINA in Genova, Italy. Project partners came together to review the progress of actions set during the previous meeting in October and looked closely at results from specific studies in the valorisation of intermediates in high added-value products and preliminary LCA and LCC evaluations.

Dissemination partners, Insight Publishers commenced the meeting providing detail on the exploitation and communication of the on-going project developments and results. This included open discussions on the first Rehap webinar, a second workshop and the project’s place in IPL’s Projects Magazine on the energy efficiency industry.

RINA continued by explaining preliminary LCA and LCC studies on four main materials: Bio-PUR, wooden boards, green concrete and PU adhesives. A short LCA/LCC session was then held with partners to revise the value chains and set benchmarks of these materials.

The second day was opened by Lars Wietschel from UNIA who have published papers on feedstock price analysis and feedstock potential with another paper planned on further work on waste management.

Pieter Brabander from BBEPP elaborated on the lab trials for the planned upscaling of processes for the fermentation of 1,4-BDO and 2,3-BDO, before Rehap coordinator Aitor Barrio led detailed discussions with partners on the on-going research and developments in the valorisation of intermediates in the high added-value products. Partners were reminded to update the Risks table when completing their research.

To round off the meeting, Martin Mosquet introduced partners focused on the application of these products in the final construction elements (concrete, wooden panels, PU adhesives, insulation). LaFarage-Holcim, Foresa, Rampf and Collanti touched on their initial plans of this process for the next six months. In particular, the parameters for the tests that need to be done to develop these products.

The next meeting is proposed to take place in November, when the actions of the next six months will be reviewed. Location TBC.

How to convert wheat straw waste into green chemicals

The development of new bio-refining technologies based on agricultural waste is seen as key to reducing Europe’s dependency on fossil-based products. According to a White Paper by the International Council on Clean Transportation, about 144 million tonnes of wheat residues accumulate each year in the EU. Supported by the EU-funded OPTISOCHEM project, researchers have made significant progress in transforming this excess material into something more useful: bio-isobutene, or bio-IBN, a key precursor for numerous chemicals.

The project involves several processes such as the conversion of wheat straw into hydrolysate and its fermentation into isobutene. This material is then converted into oligomers and polymers. A press release by project coordinator Global Bioenergies states that “currently underutilized residual wheat straw has been converted at demo scale into second generation renewable bio-isobutene, and will eventually be transformed into oligomers and polymers usable in lubricants, rubbers, cosmetics, solvents, plastics, or fuels applications.”

Planned activities

Quoted in the same press release, Jean-François Boideau, EMEA Commercial General Manager at project partner INEOS Oligomers, says: “To date, we received several batches of bio-isobutene from Global Bioenergies for qualification purpose[s], and the quality is promising. During the next phase of the project, INEOS is ready to evaluate conversion of additional quantities of bio-isobutene into downstream products in order to assess the potential of this bio-based feedstock as a building block for end consumer applications.” Frederic Pâques, COO of Global Bioenergies, adds: “We expect to produce several tons of bio-isobutene on this new non-conventional feedstock in the remaining periods of the project.”

Various benefits

The project website notes that the partners hope to make use of the “technical, economic as well as environmental/social sustainability performances” for a commercial biorefinery. The ongoing OPTISOCHEM (OPTimized conversion of residual wheat straw to bio-ISObutene for bio based CHEMicals) project is funded by the Bio-Based Industries Joint Undertaking (BBI JU), a public-private partnership between the EU and the Bio-based Industries Consortium. The project will run until May 2021.

As summarised on the BBI JU project web page, OPTISOCHEM aims to achieve a rise in “the yield of targeted bio-based product(s)” by over 20 % and lessen “production costs of bio-based products by 10-20%, compared to current market situation.” Another expected impact of the project involves “savings, in terms of CO2 emissions per kg product by more than 20% for bio-catalytic as compared to state-of-the-art production methods.” The partners also plan to cut “energy consumption by more than 30% for bio-catalytic processes.”

Overall, the BBI JU is expected to provide several environmental and socioeconomic benefits, as summarised on its website: “The new bio-based products resulting from the BBI JU will on average reduce CO2 emissions by at least 50% compared to their fossil alternatives.” It emphasises that these products will be “comparable and/or superior to fossil-based products in terms of price, performance, availability and environmental benefits.”
