The Stora Enso Group has recently launched DuraSenseTM brand wood based biocomposites. This is another major step for Stora Enso to replace fossil-based materials with renewable materials solutions. DuraSense will be a high performance, sustainable biocomposite that will replace plastics.
DuraSense can replace most fossil-based plastics by using wood-based renewable fibers. In 2017, Stora Enso Group announced that it will invest 12 million Euros in the Hylte plant in Sweden to build a biocomposite production line. The project has been put into production in 2018. After the full production, the plant will have an annual production capacity of 15,000 tons. Make it the largest wood fiber composites plant in Europe.
Jari Suominen, head of the Stora Enso Group's timber division, said: “Reducing the amount of plastic used and replacing it with renewable, traceable materials is a gradual process. With the introduction of DuraSense, we will be able to Customers provide wood fiber-based alternatives to improve performance in the sustainable sector while significantly reducing their carbon footprint, with a maximum drop of 80% depending on the product."
The DuraSense range is versatile and can be used in both consumer and industrial applications. The main application areas include furniture, pallets, hand tools, automotive parts, beauty and daily necessities, toys, kitchen utensils and caps.
DuraSense granules are made up of natural wood fibers, polymers and additives that provide plastic-like plasticity while maintaining the sustainability and processability of the wood. Based on DuraSense, we can also combine fiber with recycled polymers or bio-based polymers to further enhance environmental value. For example, DuraSenseTM Eco100 is a wood fiber-based and biopolymer-based product that is cost-competitive and can completely replace fossil-based plastics.
Patricia Oddshammar, head of Stora Enso Biocomposite Division, said: “Consumers are increasingly eager to achieve affordable sustainability and environmental protection. DuraSense can reduce the use of plastics by up to 60%, thereby reducing the environment. Residual amount of micro-plastics. Stora Enso's biocomposites can be reused seven times, recycled together with other plastics, and used for energy recovery after the end of their life cycle."
As part of the bioeconomy, Stora Enso is a leading global provider of renewable solutions for packaging, biomaterials, wood structures and paper. We believe that all products made from fossil materials today can be made of wood in the future. Stora Enso has approximately 26,000 employees in more than 30 countries and had sales of 10 billion euros in 2017. Stora Enso shares are listed on the Helsinki and Stockholm stock exchanges.
Meniscus cylinder Lens can increase the NA of the system while only adding slightly to the total spherical aberrations. The Negative Meniscus cylinder Lens is used to increase the focal length of another Cylindrical Lens while maintaining the angular resolution of the optical assembly. This lens shape is best used when one conjugate is relatively far from the cylindrical lens.
Some styles of cylindrical lenses have antireflective coatings to increase the transmission of light through the lens.
Fused silica cylinder lenses are ideal for demanding laser machining and medical applications.
