From the Sector

The current European Football Championships 2024 in Germany will be played on natural turf, which is very costly to maintain, does not tolerate high frequency of use and has a limited service life of only 6 months in some cases. Artificial turf is easier to maintain and correspondingly popular. In Germany, there are estimated to be more than 5,000 artificial turf pitches and as many as 25,500 across the EU. The drawback: the enormous annual emission of microplastics in the form of infill material, the high CO2 impact and the not environmentally friendly disposal. Researchers in Aachen presented a sustainable alternative: BioTurf is a new artificial turf system made from bio-based polymers that no longer requires polymer infill material!

"Every year, around 500 kilograms of plastic granules are produced per artificial turf pitch, which have to be refilled as infill. This also corresponds to the amount that potentially enters the environment as microplastics per sports pitch," explains Dr Claudia Post from TFI. With an estimated 25,000 artificial turf pitches in the EU, artificial turf in Europe alone produces 12,750 tonnes of microplastics that end up in the environment every year! The TFI - Institut für Bodensysteme an der RWTH Aachen e.V., Institute for Research, Testing and Certification in Europe for Indoor Building Products, has developed the innovative artificial turf system together with the ITA (Institute for Textile Technology at RWTH Aachen University) and in collaboration with the company Morton Extrusionstechnik (MET), a specialist in artificial turf fibres.

"New artificial turf pitches will be phased out by 2031 at the latest due to the ban on plastic granules. Even now, artificial turf pitches with infill material are no longer being subsidised," says Dr Claudia Post. For grassroots sports, clubs, cities and local authorities, converting their existing artificial turf pitches will be a mammoth task in the coming years, as artificial turf pitches have to be replaced every 10-15 years. With BioTurf, an environmentally friendly alternative is now available! The surface can be played on like any other, whether running, passing or kicking. Short, heavily crimped blades support longer blades and this simple approach increases playing comfort. BioTurf fulfils all quality requirements and standards for the highest footballing demands.

"BioTurf is an innovative, holistic solution," emphasises Dirk Hanuschik from TFI. "We use rapeseed oil and agricultural waste that does not compete with food production. BioTurf is also almost completely recyclable".
This is in stark contrast to conventional artificial turf, which can currently only be thermally utilised, i.e. burned to generate heat.

As BioTurf does not require the traditional latex process at all, the energy-intensive drying process can be dispensed with, which has a positive effect on the price. Latex is also difficult to recycle. In contrast, BioTurf uses the new thermobonding technology. Here, the thermoplastic pile yarns are thermally fused to the backing. Further development steps still need to be taken in the endeavour to develop a 100% mono-material artificial turf, as a few percent polypropylene still needs to be processed in the backing in addition to the polyethylene fibre material in order to protect it during thermobonding. However, this does not hinder its recyclability.

Beaulieu International Group will turn the spotlight on geotextile products with sustainability benefits to support progress in resilient civil engineering projects at the 12^th ICG Rome from 18^th -21^st September 2023, presenting options to target fossil carbon reduction by choosing PP-based staple fibres or woven geotextiles that are among the lowest in carbon footprint for geosynthetics.

For manufacturers of nonwoven geotextiles, Beaulieu Fibres International (BFI) offers PP fibres with > 25% carbon footprint reduction compared to the European standard PP fibres, generating 1.48 kg CO₂/kg PP fibres. A step further is to accelerate the replacement of fossil carbon in engineered fibre applications by choosing its ISCC Plus certified bio-attributed MONO-PP with a negative carbon footprint.

For construction projects, nonwoven geotextiles made with high-tenacity HT8 fibres are proven to secure a longer service lifetime and reduce the environmental impact, as they offer high mechanical performance at a reduced weight.

Beaulieu Technical Textiles' (BTT) woven geotextiles provide a wide range of functions, including separation, filtration, reinforcement and erosion control, and are among the most sustainable in the industry. Depending on weight, the carbon footprint of its woven geotextiles (m²) ranges between 0.37 and 1.40 kg CO₂ eq./m². They also minimize the use of natural resources for more sustainable infrastructure development. Case studies such as at the Ostend-Bruges airport highlight significant CO2 reduction on the jobsite by replacing the transport of 960 trucks of gravel with 3 trucks of woven geotextiles, and by extending the runway’s life span.

The ICG launch of its new line Terralys MF woven filtration geotextiles with monofilament boosts the performance of a common solution in building layers that require high water flow rates. High-tenacity extruded polypropylene tapes and monofilaments are interwoven to form dimensionally stable and highly permeable geotextiles. These new filtration geotextiles provide greater resistance to dirt and biological clogging. They allow water to travel freely while reducing soil erosion when employed as a separation and stabilizing layer.

As of September 2023, all PP staple fibres and woven geotextiles will have Environmental Product Declarations (EPD) based on LCAs. Each EPD is an essential tool for communicating and reporting on the sustainability performance and helps carbon-conscious customers in their purchasing and decision making. Registered EPDs are globally recognized, publicly available and free to download through EPD Libraries.

• Spunbond, meltblown and composite structures for new market opportunities

RadiciGroup is participating with its Advanced Textile Solutions business area at Index in Geneva from 18 to 21 April 2023. Among the Group’s products showcased are spunbond and meltblown for different application sectors, such as roofing, construction, automotive, HO.RE.CA. and filtration.

“The key message we are bringing to the fair is sustainability,” noted Enrico Buriani, CEO of the Nonwovens division of RadiciGroup Advanced Textile Solutions. “Those who already know us know that, for many years, the Group has been focused on proposing low environmental impact products and processes where sustainability is scientifically measured or certified by independent third parties. Our company is dedicated to nonwovens, which, by the way, are produced using 100% renewable energy. We have expanded our portfolio of innovative solutions for customers interested in realizing projects with sustainability as an essential requirement.”

Respunsible® is a spunbond brand manufactured from recycled polypropylene. A preliminary Life Cycle Assessment (LCA) study was carried out by RadiciGroup to demonstrate the correlation between the reduction in environmental impact and the percentage increase in recycled material. The final results demonstrate that a variable percentage of from 50 to 70% recycled material leads to a reduction in CO2 emissions of from 30 to 40%, compared to a fabric made of 100% virgin material, without comprising high technical performance.

Additionally, since RadiciGroup has achieved ISCC PLUS certification (International Sustainability and Carbon Certification), it can offer bio, biocircular or circular polypropylene spunbond and meltblown nonwovens, in which the sustainable polypropylene is biomass balanced. This certification signifies traceability along the supply chain and verifies that the certified companies meet high environmental and social standards.

“Since 2020, we have had a technologically advanced meltblown production line,” Mr. Buriani concluded. “This allows us to make composite structures, sold under the brand name Radimelt®. Now our goal is to expand our filtration applications, diversifying and developing new business, for instance vacuum cleaner bags or HVAC (heating, ventilation and air conditioning) system filters, where we can meet the high efficiency and mechanical resistance demanded, thanks to our latest generation technology.”

Moreover, RadiciGroup is participating in a forum organized by the Technical Textiles Section of Sistema Moda Italia in collaboration with the Italian Space Agency (ICE) (Hall 12.1 – Stand C58), with the goal of introducing product innovations not only coming from a single manufacturer, but also from an innovative synergistic approach all along the supply chain, from raw materials to finished products. An example of this synergistic collaboration is the “Mars Spacesuit”, recently tested in the USA by analogue astronauts as part of a space medicine project designed to measure the vital signs of future astronauts and develop technologies to support the simulation of life in space and planetary environments. RadiciGroup teamed up with major Italian textile companies and supplied the materials to make the suits for the six analogue astronauts participating in the mission and coordinated the development of the technologies needed to create the technicalwear for use in extreme environmental conditions.

Trützschler Man-Made Fibers introduces OPTIMA for IDY and expands the range of the OPTIMA extrusion systems by the industrial yarn (IDY) sector. In addition to OPTIMA for carpet yarns (MO40-C, MO40-E and TO40), variants for manufacturing (semi-)industrial multifilament yarns are now joining the line.

Since 2012, Trützschler has been developing and building high-performance extrusion lines for carpet yarns (BCF - Bulk Continuous Filament) and industrial/technical yarns made of polyester, polyamide and polypropylene. The market launch of the OPTIMA concept for BCF took place in 2019 and has established itself in the markets since then. OPTIMA was designed as a modular platform and now also includes solutions in the IDY (InDustrial Yarn) sector.

OPTIMA systems for industrial yarn (TEC-O40 and TEC-O80) impress with flexibility application and end product diversity. Both concepts offer a wide range of design options and can be tailored precisely to meet end product and the throughput requirements.

OPTIMA enables the production of high-tenacity yarns for shoelaces, ropes and nets as well as low-shrinkage qualities for tire cords, truck tarpaulins and airbags. As the lines are modular, they can be quickly adapted to new market developments and end products.
