First project factsheet

Rehap has published an informative and fun factsheet to highlight some of the research and results currently developing, and taking a look at what lies ahead for the project.

The factsheet, the first in a series, explains some of the first publishable results from the project and is titled, “Assessing the availability of agroforestry residues”.

A brief description of what the project is doing was mentioned, before presenting a picture on how the project went about collecting the right data to understand which agriculture and forestry residues are available, and where, and how they can be used sustainably for the creation of bio-based construction materials.

The factsheet highlights the results and the next stage of the project, involving the development of a methodology tool to forecast the potential waste residues across the EU till 2030.

There will be more factsheets coming your way, so keep your eyes on the website. (You will be able to find them on the website under Publications).

New guidelines on cascading use fail to meet expectations of EU’s new Bioeconomy Strategy

The guidelines should be aligned with the new EU strategy to make the bioeconomy more circular.

Today’s publication of the non-binding guidelines on the cascading use of wood fails to live up to the Commission’s own ambitions signalled in its recent Bioeconomy Strategy. CEPI has been a long-time proponent of this principle which allows for every wood fibre to be used on average 2.5 times, instead of solely burning wood for bioenergy.

“The cascading use of principle works automatically in a well-functioning market but unsustainable subsidies distort wood markets” says Ulrich Leberle, Raw Materials Director of CEPI, the European forest fibre and paper industry. “The new guidelines should be aligned with the new EU strategy to make the bioeconomy more circular. They should also take into account any assessment of Member States that encourages the application of these principles in their bioenergy support schemes.

The new guidelines ignore the firm call set out by the revision of the Renewable Energy Directive, approved yesterday, to avoid raw material market distortions and neglect to provide clear instructions on this in the new guidelines.

The guidance is clearly a missed opportunity for contributing to a circular bioeconomy that is built on the efficient use of biomass and innovative solutions rather than on direct burning of wood for bioenergy. The focus should now turn to ensuring that Member States respect the cascading use of principle in their national climate and energy plans and that future revision of these guidelines take account of this principle.

Press Release: European bioeconomy showing positive developments, according to Rehap workshop

Rehap is an EU-funded project that aims to use agroforestry waste to create products for the construction industry. Its most recent workshop looked at how projects in similar sectors are swiftly developing new and advanced technologies and processes for the production of bio-based products and materials from biomass.

The EU project Rehap recently hosted a workshop to explore the matter of the availability of raw materials that can be used in the bioeconomy. The bioeconomy comprises those parts of the economy that use renewable biological resources from land and sea – such as crops, forests, fish, animals and microorganisms – to produce food, materials and energy.
There is concern shared across the EU about the long-term viability of how we use our renewable natural resources in the bioeconomy. A report published by the European Environment Agency in August 2018, “The circular economy and the bioeconomy”, revealed that the EU wants to progressively intervene in the areas of food waste, biomass and bio-based products. As the bioeconomy continues to rapidly grow, these areas are under increased pressure to tackle expanding supply and demand issues and shifts in the availability of land.
The workshop, which was held on 27 September at the University of Augsburg, Germany, promoted successful cases for bio-based products and materials, as well as detailed results from the ongoing Rehap project. Presentations focused on the techniques and bottlenecks of the technologies and processes used in both Rehap and other projects, with a focus on the availability of raw materials.
Dr Klaus Richter from the Technical University of Munich gave a presentation on the “cascading use” of wood. This involves prioritising value-adding non-fuel uses of wood, so it is only burned for energy after it has been used, re-used and recycled as much as possible. The WoodWisdom EraNet project was given as an example of how this approach can be used in the forestry sector.
The Rehap project presented its developments in using advanced technologies to make sure the products it is making – bio-based products for the construction industry – are as sustainable as possible. This included an assessment of the availability of waste biomass in the EU agroforestry sector up until 2030, and the development of a supply network for the transportation of this biomass.
The presentation also revealed how the sustainability of Rehap products and materials may actually help boost their deployment both within and outside the construction sector.

Attis Industries launches new video series to promote lignin conversion process.

“Our goal is very simple – it is to revolutionise biomass processing to reduce our dependence on fossil fuels.”

Lignin, along with cellulose and hemicellulose, makes up most plant materials. Historically, lignin was often considered an afterthought in the biomass world. However, US-based Attis Industries has developed a biomass processing technology that produces high-value applications from lignin. At the start of the month, the company announced that it would be launching a series of videos that would give investors and interested parties additional information on the technologies and bio-based products offered under the firm’s innovations division.

In the first video, Attis CEO Jeff Cosman and policy director Helen Petersen discuss the current inefficiencies in biomass processing and how the company is using by-products from the pulp and paper industry to double biofuel output.

According to the company, Attis can recover around 1.3 pounds of high-purity lignin for every pound of cellulose ethanol it produces. The concentrated carbon can then be used to make bio-plastics and adhesives or can be converted into petrol or diesel.

According to German-based University of Freiburg, every year around 50 million tonnes of lignin accumulate as a by-product of the paper industry. Plants produce around 20 billion tonnes of lignin every year.

Speaking in the video, Cosman said: “Our goal is very simple – it is to revolutionise biomass processing to reduce our dependence on fossil fuels.”

Peterson added: “Our [processing] outputs include pulp and a unique form of high purity lignin.

“While the pulp can be used in traditional pulp and paper markets or to produce cellulosic ethanol, it’s this high purity form of lignin that allows Attis to substantially increase the value and products made from biomass.”

Press Release: New paper provides forecast of agricultural harvesting residues in Europe

A new and spatially accurate forecast of the available waste biomass from agricultural activity in Europe has been made, with the results soon to be published. This data, gathered as part of the Rehap project, can be used by the second-generation bioconversion industry to drive Europe towards a post-petroleum age where materials and fuels are made from renewable resources. 

The European Commission has recently been pushing a more sustainable renewable resource strategy, with the aim of ensuring food security, managing natural resources sustainably, and reducing dependence on non-renewable and unsustainable resources.

Part of this strategy involves modelling, mapping and accurately understanding the available biomass in the agroforestry sector. The idea is to find out what biomass is available across Europe, which could be used to create materials which are normally derived from fossil fuels.

In light of increasing demand for sustainably-sourced biomass, the EU-funded project Rehap is soon to publish a paper that uses new methods to provide a spatially explicit forecast of biomass potentials from the agricultural sector that are available for conversion into useful products.

The paper outlines the materials and methods of this forecast prediction, data on the specific raw material yields and potentials, and results on the forecasted agricultural residue potentials of biomass until the year 2030 in the EU.

The broader aim of the Rehap project is to create new materials for the construction sector that are derived from agricultural and forestry waste. This new and spatially explicit forecast of where and when this waste can be found in Europe will ensure that any biomass they use is sustainably-sourced.

The publication of this paper will also provide other researchers access to the new and improved forecast, facilitating a significant step towards a greener and more resourceful use of natural resources in Europe, whilst promoting a more competitive bioeconomy.

By conducting this research, Rehap is leading the way in furthering the new EC strategy, as the results from this forecasting can be used for decision-making by those working in the bioeconomy to ensure that any biomass being used is not required for cultivation in agriculture, but will be facilitating the progression of the circular economy without damaging other sectors.

The paper, "Spatially explicit forecast of feedstock potentials for second generation bioconversion industry from EU agricultural sector until the year 2030", has been published in the Journal of Cleaner Production.

Project poster presented at Nordic Wood Biorefinery Conference

Rehap’s latest developments in creating novel materials from agoforestry waste for use in the construction industry were presented at the 8th Nordic Wood Biorefinery Conference in October.

The Nordic Wood Biorefinery Conference (NWBC), the leading meeting forum for wood biorefinery professions, took place at the Scandic Marina Congress Centre in Helsinki, Finland on the 23-25 October 2018, hosted by VTT.

Karel De Winter, team leader in bioprocessing at Bio Base Europe Pilot Plant (BBEPP) and his colleagues presented the poster, “Creating novel materials from agricultural and forestry waste” as part of the Rehap project.

BBEPP, partner of Rehap, is tasked with developing and scaling-up new or existing bio-based and sustainable processes to an industrial level. The research that was presented at NWBC focused on the extraction of tannins, lignin and carbohydrates from spruce bark. A detailed study on soda cooking and the subsequent isolation of lignin was completed before the processes were scaled.

The poster explained the soda cooking process and the precipitation of lignin. The soda cooking conditions were originated and developed by VTT, the latter was further developed by BBEPP and some optimisation on how to isolate the lignin took place. The poster presents some of these results.

BBEPP also developed these precipitation and filtration processes at lab scale before testing them at pilot scale, processing 600kg of bark and demonstrating their scalability. Results revealed the amount of lignin available. The poster can be found here.

The Rehap poster was among a turnout of 34 posters at the conference.

The NWBC programme also covered a range of topics in the form of keynotes and talks on forests, dealing with desire and greed in transforming environment; policies and global megatrends; industrial developments in biorefinery; new concepts and applications from wood based raw material; side streams into value-added products; processing and tailoring properties; and the application of these processes.

The conference provided detailed insight from paper and pulping industries, revealing a lot of work being done on the validation of lignin and the use of this material in other industries. There was also a number of discussions on the alternative uses of bark for fuel processes by burning it and using it for energy. For Rehap, this opened up questions as to whether this alternative strategy has place within the project.

Rehap partake in Iberoamerican Biorefineries Conference

Running for its fourth year, the noteworthy Iberoamerican Congress on Biorefineries took place in Jaén, Spain and partner, Bio Base Europe Pilot Plant presented on their work and involvement in Rehap.

For 2018, the Iberoamerican Congress on Biorefineries returned to Jaén in Spain for the fourth edition (4-CIAB) on the 22-26 October, where the Iberoamerican community on biorefineries could network, share and gain new knowledge on the current developments happening in the field in both Europe and across the pond in Latin American countries.

The Iberoamerican Congress on Biorefineries has previously taken place in Los Cabos, Baja California (Mexico) in 2012, Jaén (Spain) in 2013 and Concepción (Chile) in 2015. The congress of Iberoamerican comprises of countries or territories in the Americas where Spanish or Portuguese are the predominant language, with Spain and Portugal included in this definition.

Across the two-day event there were 12 main sessions that were led by a keynote speaker and followed by a range of oral presentations from various projects and expert speakers. The sessions included, but not limited to:

  • Biomass for biorefineries
  • Biochemical processes
  • Green chemistry
  • Advances in biorefineries
  • Techno-economic evaluation, sustainability and LCA analysis
  • Lignin production and applications

Rehap, represented by partner Bio Base Europe Pilot Plant (BBEPP), took part in the session, Ongoing biorefinery projects, chaired by Frederik de Bruyn from BBEPP and Caterina Call from IMECAL.

BBEU’s presentation discussed what it is doing as a multi-purpose pilot facility for bio-based products and processes, why piloting is important and the role they play in various partner projects, including Rehap: hot water extraction of tannins, solid liquid separation of the bark residues, scale-up of soda cooking, solid liquid separation after soda cooking, scale-up of the lignin precipitation and of the enzymatic hydrolysis.

In the wider biorefinery industry, it was noted that there is currently a lot of ongoing work involved with the agroforestry waste industry and the organic fraction of municipal solid waste and forestry waste such as residue leaves, pruning or dedicated crops.

(Based on the works presented at the 4-CIAB, Industrial Crops and Products will publish a special issue looking at: Biomass Fractionation; Bio-based products and materials; Bio-based Energy.)

New process for full use of softwood bark ready for production

The pulp and paper industry and the wood product industry in Finland together produce three million tonnes of softwood bark as waste every year. Most of this is used in energy production, but useful raw materials can also be extracted from softwood bark to create bio-based products and materials. Rehap partner VTT has developed a method to extract a high yield of tannins from bark.

Softwood bark is available in significant quantities, not just in Finland but in a number of locations across Europe, and it has a lot of potential when it comes to the opportunities it can provide the future bioeconomy. VTT has developed a method to extract high yields of pure tannins from softwood bark for use as a raw material for producing resins used in wood products and other material applications. The residual fibre fraction can be used to produce sugar for fermentation products.

Traditionally, tannins are extracted from the bark by hot water extraction. The extraction yield will differ slightly depending on the origin and processing history of the raw material, but it is usually fairly low. For example, the yield from Scandinavian spruce and pine bark is around 10 per cent of the bark’s weight. In addition, using the leftover bark residue as a source of sugar through enzymatic hydrolysis produces low yields, with much of the tannin and carbohydrates in the bark remaining unused.

The new process developed by VTT closely resembles the kraft process used to convert wood into wood pulp, using higher alkaline conditions and higher temperatures than hot water extraction. One third of the bark’s weight can be isolated as a much purer tannin fraction through this process. The fibre fraction can also be hydrolysed far more easily than after hot water extraction.

VTT is a key partner in the EU-funded Rehap project, which is looking to create high-added value products for the construction industry from the agroforestry waste available across Europe. VTT has been developing the extraction, fractionation and purification protocols for the recovery of tannin, lignin and sugars from softwood barks.

BBEPP, FORESA and BIOSYNCAUCHO, all Rehap partners, also participated in the development and validation of the new patented process and the resulting fractions.

ArboSkin pavilion made from bioplastic by ITKE

The spiky modules used to build this curving pavilion in Stuttgart, Germany, are made from a bioplastic containing over 90 percent renewable materials (photography by Roland Halbe).

Students and professors from Stuttgart University's ITKE (Institute of Building Structures and Structural Design) designed the freeform facade to demonstrate the structural properties of a new bioplastic developed specially for use in the construction industry.

Bioplastics are plastics made from renewable biomass sources such as starches, cellulose or other biopolymers, that offer sustainable alternatives to plastics derived from fossil fuels. The bioplastic used in the ArboSkin project is called Arboblend and is produced by German firm, Tecnaro, by combining different biopolymers such as lignin – a by-product of the wood pulping process – with natural reinforcing fibres.

"Thermoformable sheets of bioplastics will represent a resource-efficient alternative [to oil-based plastics, glass, or metal] in the future, as they combine the high malleability and recyclability of plastics with the environmental benefits of materials consisting primarily of renewable resources," explained the project team.

The pyramidal modules are made by extruding bioplastic granules into sheets before thermoforming them to create the faceted shapes and trimming off the excess material.

The double-curved skin is formed by linking the pyramids together, with bracing rings and joists helping to create load-bearing walls.

CNC-milling was used to remove sections from some of the modules, creating apertures in the facade. The waste material from this process can be re-granulated and fed back into the production process, while the plastic sheets can be composted at the end of their life.

ArboSkin Bioplastics Facade Mock Up by ITKE

Mock-Up: The bioplastics facade mock-up was created within the framework of the Bioplastic Facade Research Project, a project supported by EFRE (Europäischer Fonds für Regionale Entwicklung / European Fund for Regional Development). It demonstrates one of the possible architectural and constructional applications of bioplastic materials developed during the course of the project. The blueprint is based on a triangular net composed by mesh elements of varying sizes.
