From the Sector

The DITF is leading the joint project "DACCUS-Pre*". The basic idea of the project is to develop a new building material that stores carbon in the long term and removes more CO₂ from the atmosphere than is emitted during its production.       

In collaboration with the company TechnoCarbon Technologies, the project is now well advanced - a first demonstrator in the form of a house wall element has been realized. It consists of three materials: Natural stone, carbon fibers and biochar. Each component contributes in a different way to the negative CO₂ balance of the material:

Two slabs of natural stone form the exposed walls of the wall element. The mechanical processing of the material, i.e. sawing in stone cutting machines, produces significant quantities of stone dust. This is very reactive due to its large specific surface area. Silicate weathering of the rock dust permanently binds a large amount of CO₂ from the atmosphere.

Carbon fibers in the form of technical fabrics reinforce the side walls of the wall elements. They absorb tensile forces and are intended to stabilize the building material in the same way as reinforcing steel in concrete. The carbon fibers used are bio-based, produced from biomass. Lignin-based carbon fibers, which have long been technically optimized at DITF Denkendorf, are particularly suitable for this application: They are inexpensive due to low raw material costs and have a high carbon yield. In addition, unlike reinforcing steel, they are not susceptible to oxidation and therefore last much longer. Although carbon fibers are more energy-intensive to produce than steel, as used in reinforced concrete, only a small amount is needed for use in building materials. As a result, the energy and CO₂ balance is much better than for reinforced concrete. By using solar heat and biomass to produce the carbon fibers and the weathering of the stone dust, the CO₂ balance of the new building material is actually negative, making it possible to construct CO₂-negative buildings.

The third component of the new building material is biochar. This is used as a filler between the two rock slabs. The char acts as an effective insulating material. It is also a permanent source of CO₂ storage, which plays a significant role in the CO₂ balance of the entire wall element.

From a technical point of view, the already realized demonstrator, a wall element for structural engineering, is well developed. The natural stone used is a gabbro from India, which has a high-quality appearance and is suitable for high loads. This has been proven in load tests.  Bio-based carbon fibers serve as the top layer of the stone slabs. The biochar from Convoris GmbH is characterized by particularly good thermal insulation values.

The CO₂ balance of a house wall made of the new material has been calculated and compared with that of conventional reinforced concrete. This results in a difference in the CO₂ balance of 157 CO₂ equivalents per square meter of house wall. A significant saving!

The kick-off meeting for the "Trends and Design Factors for Hydrogen Pressure Vessels" project, recently held at AZL Aachen GmbH, was a successful event, bringing together more than 37 experts in the field of composite technologies. This event laid a solid foundation for the Joint Partner Project, which currently comprises a consortium of 20 renowned companies from across the composite pressure vessel value chain: Ascend Performance Materials, C evotec GmbH, Chongqing Polycomp International Corp. (CPIC), Conbility GmbH, Elkamet Kunststofftechnik GmbH, F.A. Kümpers GmbH & Co. KG, f loteks plastik sanayi ticaret a.s., Formosa Plastics Corporation, Heraeus Noblelight GmbH, Huntsman Advanced Materials, Kaneka Belgium NV, Laserline GmbH, Mitsui Chemicals Europe GmbH, Plastik Omnium, Rassini Europe GmbH, Robert Bosch GmbH, Swancor Holding Co. Ltd. Ltd., TECNALIA, Toyota Motor Europe NV/SA, Tünkers do Brasil Ltda.

The project follows AZL´s well proven approach of a Joint Partner Project, aiming to provide technology and market insights as well as benchmarking of different material and production setups in combination with connecting experts along the value chain.

The kick-off meeting not only served as a platform to foster new contacts and get informed about the expertise and interests of the consortium members in the field of hydrogen pressure vessels, but also laid the groundwork for steering the focus of the upc oming project's ambitious phases. As a basis for the interactive discussion session, AZL outlined the background, motivation and detailed work plan. The central issues of the dialogue were the primary objectives, the most pressing challenges, the contribut ion to competitiveness, and
the priorities that would best meet the expectations of the project partners.

Discussions covered regulatory issues, the evolving value chain and the supply and properties of key materials such as carbon and glass fibres and resins. The consortium defined investigations into different manufacturing technologies, assessing their matu rity and potential benefits. Design layouts, including liners, boss designs and winding patterns, were thoroughly considered, taking into account their implications for mobile and stationary storage. The group is also interested in cost effective testing m ethods and certification processes, as well as the prospects for recycling into continuous fibres and the use of sustainable materials. Insight was requested into future demand for hydrogen tanks, OEM needs and strategies, and technological developments to produce more economical tanks.

The meeting highlighted the importance of CAE designs for fibre patterns, software suitability and the application dependent use of thermoset and thermoplastic designs.

The first report meeting will also set the stage of the next project phase, which will be the creation of reference designs by AZL's engineering team. These designs will cover a range of pressure vessel configurations using a variety of materials and production concepts. The aim is to develop models that not only re flect current technological capabilities, but also provide deep insight into the cost analysis of different production technologies, their CO₂ footprint, recycling aspects and scalability.

AZL's project remains open to additional participants. Companies interested in joining this initiative are invited to contact Philipp Fröhlig.

As part of Sappi Europe's full scale decarbonisation roadmap, Gratkorn mill is expanding the share of biomass to be used as an energy source, further driving the move away from fossil fuels as part of the mill’s contribution to the European roadmap. The project follows the recent modernisation of the power plant boiler which enabled the shift from coal to a combined approach of biomass and natural gas.

The mill is now embarking on a next step, enhancing its infrastructure and therefore capacity in order to handle the delivery, sorting and processing of increased biomass levels. This increased utilisation requires an improved biomass handling system at the mill as well as decentralised intermediate storage terminals within the surrounding regions.

"With our long-standing competent wood sourcing partner Papierholz Austria, we will continue our journey to move away from fossil fuels at Gratkorn mill and work towards a climate-neutral future”, says Peter Putz, Managing Director of Sappi Austria GmbH.

For the near term, Sappi’s decarbonisation roadmap includes close to 80 projects being carried out across its European mills by 2025.

“Our 2025 roadmap identifies the path we have embarked on towards a carbon-neutral future,” explains Sarah Price, Director Sustainability of Sappi Europe. The objective is to reduce emissions of specific greenhouse gases (Scope 1 and 2) by 25 per cent and to increase the share of renewable energy in Europe to 50 per cent by 2025 (compared to 2019). Additionally, Sappi’s 2030 science-based target is to reduce carbon emissions by 41.5% per ton of product. “We’re already making good progress towards these targets, with a large number of projects already well-underway or completed”.

Price Trends

• The nearby cotton futures contract on the Intercontinental Exchange was down just 1% in December and closed the year at $1.84 per kilogram. A year earlier, the March contract closed at $2.30 per kilogram.  
  
  Cotton futures have been inverted for nearly three years because of supply chain disruptions that prevented normal on-time deliveries of international shipments. With the easing of container shortages and increased sailings, cotton futures are gradually reverting to the normal pattern in which contracts for forward delivery exceed nearby contracts by the cost of insurance, storage and interest between delivery months. The May and July 2023 contracts also finished 2022 at $1.84 per kilogram. In November, the May and July contracts were each several cents per kilogram lower than the March contract.
• The Eastern Market Indicator of prices for fine wool in Australia rose 9% in December to US$9.06 per kilogram. A year earlier, the EMI was $9.66. Australian analysts note that sheep for meat, cattle, and grain production, are competing alternatives for the use of land, and wool prices must continue upward if production is to be maintained in 2023.
• Prices quoted by the Indian Jute Balers Association (JBA) at the end of December converted to US$ fell 2% from a month earlier to an average of 74 cents per kilogram. The decline occurred entirely because of a weakening exchange rate. Prices in Rupee rose marginally. A year earlier, quoted prices averaged 84 cents per kilogram. The 16-percent decline year-on-year was caused about equally by a decline in quoted prices in Rupee and a weakening of the exchange rate.  
  
  The Indian jute industry is almost entirely focused on domestic demand, while half of total demand in Bangladesh comes from exports. Because of shortages of higher quality jute, export prices in Bangladesh are reportedly rising.

  India extended the anti-dumping duty at the end of December on jute and jute products imported from Bangladesh and Nepal for a period of five years. Bangladesh had urged the Indian government not to accept recommendations for extension, while the Indian industry was lobbying to ensure the duty remained in place. The duty rates range from approximately $6 per tonne at current exchange rates for low-quality fibres to $350 per tonne for finished products. The duty was originally imposed in January 2017 and was to expire at the end of 2022.
• Prices of silk in China rose 2% during December to US$28.0 per kilogram. Prices in yuan fell marginally during the month, but the RMB rose 3% against the USD. Prices of textile-grade silk in China were essentially unchanged at the end of 2022 compared with the end of 2021. However, prices closed 2022 about 40% above the average level pre-Covid. https://www.sunsirs.com/uk/prodetail-322.html and  https://businessanalytiq.com/procurementanalytics/index/raw-silk-price-index/ .
• Coconut coir fibre in India quoted in US$ remained in a narrow range, averaging $0.205 per kilogram in December. Prices in Rupee have been stable, and changes in dollar prices reflect changes in the exchange rate.

 
Production
 
World Natural Fibre Production in 2022 is estimated as of early January at 32 million tonnes, approximately one million below production in 2021 and down 900,000 tonnes compared with the estimate in early December.

World cotton production is estimated at 24.2 million tonnes in 2022/23 (August to July), 700,000 tonnes lower than in 2021/22 (ICAC.org). World cotton production rose from 20 million tonnes to 25 million between 2020/21 and 2005/06, but there has been no growth in the nearly two decades since.  
 
World production of jute is forecast down nearly 400,000 tonnes in 2022 because of inadequate rainfall during the harvest period to permit proper retting. Production in India is estimated up by 100,000 tonnes to 1.7 million tonnes, but production in Bangladesh fell by nearly one-third to just one million tonnes.
 
Production of coir, flax and sisal in 2022 are each estimated based on recent trends. Coir and flax have each been trending upward over the past decade, while world sisal production has been largely stable.

World wool production is forecast up 5% in 2022 to 1.09 million tonnes (clean), the highest since 2018. The Australian Wool Production Forecasting Committee issued its third estimate of 2022/23 production in December, keeping the estimate unchanged from September. Above-average rainfall in Australia, and across most of the Southern Hemisphere, is resulting in better pasture conditions and a rebuilding of sheep numbers. Sheep numbers shorn in Australia are climbing from 67 million in 2020/21 to 72 million in 2021/22 and to an estimated 75 million in 2022/23. https://www.wool.com/market-intelligence/wool-production-forecasts/  
 
According to the International Sericulture Commission (https://www.inserco.org/), silk production in China dropped from 170,000 tonnes in 2015 to 53,000 in 2020, with further declines estimated during Covid. Consequently, world silk production dropped from 202,000 tonnes in 2015 to 92,000 in 2020, and estimates of production during 2022 remain below 100,000 tonnes.

Trützschler Card Clothing (TCC), technology leader in the manufacture of high-performance card clothings for textile yarn processing, is expanding its site in Neubulach, Germany. With the twelve-million-euro investment, the supplier for the international textile machinery industry is expanding its production, warehouse and office capacities. A groundbreaking ceremony will take place during the coming winter.

The new building will expand the warehouse and logistics area by 600 square meters, to make a total area of 2,800 square meters. In the optimized cube of the new hall, a modern warehouse system will double the storage capacity. There will also be a fully automated warehouse for coils for sawtooth wires. During the construction phase, logistics and shipping will be temporarily outsourced to Pforzheim-Büchenbronn.

The move into the new building is planned for 2024. TCC will also expand the range of services and the production intensity at the site, while optimizing the process flows. Trützschler intends to recruit the additional employees required within a short timeframe by hiring new staff and offering apprenticeships at the Neubulach site. TCC employs more than 130 people in Germany, with a further 220 people employed worldwide at locations in Brazil, China, India, Mexico, Turkey and the USA.

Overall, the production area will be expanded from 4,000 to 5,400 square meters. This will enable the process flows to be optimized. The office space will be increased to 1,000 square meters. An additional level of the building will provide modern workplaces for administration and sales.

The new building will also improve access and exit routes for truck traffic. This will provide considerable relief for the local neighborhood in terms of noise emissions and other factors. Good integration into the region is very important to Trützschler. All contracts for planning, construction and air conditioning technology have been awarded to local companies.

In the future, TCC will operate its production facility in Neubulach in a climate-neutral manner. This will contribute important progress toward achieving the ambitious climate goals of the Trützschler Group. The new production facility will meet the highest requirements for energy efficiency and climate protection. Heating is provided by process heat recovery and geothermal energy. In addition, the company produces green electricity via its own solar panels.

"By expanding our business here in Neubulach, we are strengthening our presence in this area and our leading global market position too," says Managing Director Peter Gäbler. The Trützschler Group SE is also investing in India to build a new site with over 100,000 square meters for the Spinning, Card Clothing and Nonwovens business units. "It is important to be close to the customer worldwide because our foreign companies make a significant contribution to the success of the Group," says Gäbler.

TCC achieved another record sales result in 2021. Demand for the technology components for carding fibers in spinning mills and for carding in nonwovens production has increased significantly. The steel sawtooth wires, which are wound onto coils and produced for customers around the globe, eventually get worn down by use in production processes – so it is necessary to replace them regularly. For this reason, further growth is expected in 2022 and beyond.

A huge logistics hub which is set to become AkzoNobel’s largest warehousing base in China is on course to be completed by the middle of 2023.

Located at the company’s decorative paints site in Songjiang, Shanghai, the new €10.3 million facility – a nerve center for production, storage and transport – will use intelligent digital technologies and advanced security management to customize storage and operation modes for different product categories.

“Eastern China is a strategically important region for us and the new facility will ensure that we’re well placed to meet the steady growth in demand which is expected over the next ten years,” says Mark Kwok, AkzoNobel’s President of China/North Asia and Business Director for Decorative Paints China/North Asia.

Equipped with a heat-insulating and light-permeable roof – along with nearly 5,000 solar panels that will generate 1.6 million kWh of electricity – the new facility will collect clean energy and use it for warehouse and office lighting, as well as charging forklifts.

The use of clean energy, logistics optimization and the automation of warehouse operations will make an important contribution to the company’s ambition of cutting carbon emissions by 50% and moving to 100% renewable electricity by 2030.

Earlier this year, AkzoNobel also announced that it was investing in a new production line for water-based texture paints in Songjiang. The new 2,500 square meter plant will boost capacity for producing Dulux products for various markets.

The new warehousing facility is scheduled for completion in May 2023.

The adidas TERREX HS¹ is one of the first knitted products to be made in part with Spinnova technology. At least 30% of the fabric in this mid-layer hiking hoodie comes from wood-based SPINNOVA® fibres (other fibres)* and 70% from cotton (organic).

Adidas is committed to helping End Plastic Waste via a three-loop strategy that consists of using recycled materials, materials that can be made to be remade and in the case of Made with Nature, products created in part with natural ingredients, such as the adidas TERREX HS¹.  

The first product to emerge from this partnership, the adidas TERREX HS¹ mid-layer is a piece of multi-functional gear that works on the trails and then rolls up into its hood for easy storage or to create a pillow on longer adventures. It was designed using UNITEFIT – an all-gender fit system created with a spectrum of sizes, genders, and forms in mind.

Made in part with Spinnova technology , a minimum of 30% of the fabric in the adidas TERREX HS¹ comes from wood-based SPINNOVA® fibres (other fibres)* that are made by grinding wood pulp with water into a paste and then spun into a textile fibre.

The product also works with the material’s natural color. Since no dyeing or bleaching is applied, in turn this uses less water compared to the standard dyeing process.
