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!

Panda Biotech announced that building construction is complete and the official commissioning process to bring its Panda High Plains Hemp Gin™ (the “Panda Hemp Gin”) project online began in early Q4. The commissioning process marks the final stage before beginning commercial operations in Q1 2024 at the 500,000 square foot Wichita Falls, Texas facility. The Panda Hemp Gin will process 10 metric tons of industrial hemp per hour to produce textile-grade fiber, hurd, short-fiber hurd mix, and a nutrient-rich co-product that will be pelletized. The facility is expected to be the largest hemp decortication center in the Western Hemisphere and among the largest in the world.

Using only renewable energy sources, the engineering and production process at the Panda Hemp Gin has been certified green by Mid-South Engineering Company, in accordance with the International Capital Market Association’s Green Bond Principles. Panda Biotech has also partnered with Oritain, a scientific traceability company, to bring the most traceable hemp grown 100 percent in the United States to market.

Additionally, Panda Biotech is actively signing contracts with producers to grow the hemp feedstock for the 2024 growing season, as well as purchasing hemp fiber that has already been harvested or processed. The company recently unveiled an unmatched pay-to-grow program for producers to begin growing Panda hemp. With up-front, guaranteed money and agronomy support, Panda producers also receive tested and proven seed at no cost, successfully mitigating the risk producers may assume and underscoring Panda’s commitment and promise to the farming community. The benefits of growing hemp are substantial, as it is an excellent rotational crop that remediates the soil and provides a competitive margin.

“Each piece of the Panda Hemp Gin production line, including the three miles of overhead pneumatic duct lines, refining, blending, mechanical cottonization, hurd bagging and storage, baling, and more, must be individually started, checked, balanced, and commissioned,” says Panda Biotech Executive Vice President Scott Evans. “Currently, all equipment is individually being brought online to be officially placed in service.”

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.

Teijin Carbon Europe introduces a new thermoplastic carbon fiber tape (TPUD) based on PPS. The new Tenax™ TPUD with PPS matrix allows entry in new cost-sensitive markets while offering the typical TPUD advantages like high resistance to chemicals and solvents, low flammability, storage or shipping at room temperature and recyclability.  

Due to its flame retardant properties and low smoke emission, it can be used in interior applications of aircraft or rail vehicles, among others. The maximum continuous operating temperature is up to 220 °C. Very low water absorption, excellent creep resistance even at elevated temperatures and high dimensional stability round off the property portfolio of this new TPUD. It is therefore also suitable for demanding applications in the aerospace, oil & gas, sporting goods or industrial sectors, while remaining cost-effective. These properties make the product perfect for highly automated processing routes such as ATL or AFP in combination with overmolding for complex geometries. Production start for the Tenax™ TPUD with PPS matrix is the first quarter in 2021.

For almost 10 years, unidirectional tapes (TPUD) have been manufactured from carbon fibers and thermoplastics in Heinsberg, Germany. The semi-finished products have so far been offered with PEEK or PAEK – and PPS is now added to the list of available matrixes. PPS allows a lower process temperature compared to PEEK or PAEK. For the industrial market in particular, increasing the production rate to make processes more cost-efficient is an opportunity.
