As environmental awareness increases, more and more brands and consumers are paying attention to the application of sustainable materials to reduce the burden on the environment. Recycled Polyurethane (Recycled PU) is one of the eco-friendly materials that has attracted widespread attention, especially in the backpack industry, where more and more companies and designers are choosing it to produce their products.   What is Recycled PU? Recycled PU, also known as recycled polyurethane, is made from recycled PU materials (such as production waste or discarded items) through processing and regeneration. Typically, these PU waste materials go through processes such as crushing, melting, and reshaping to be turned into reusable polyurethane raw materials. This process not only reduces waste generation but also decreases the dependence on new resources. Recycled PU not only retains the softness, wear resistance, and waterproof advantages of traditional PU but also has a more environmentally friendly production process. Therefore, recycled PU, which combines environmental protection and high performance, is an important material for the fashion and luggage industry to achieve sustainable development goals. Main Features of Recycled PU Environmentally Friendly: The production process of recycled PU uses recycled materials, reducing the exploitation of natural resources. This not only lowers the carbon footprint but also reduces the accumulation of PU materials in the natural environment. High Durability: Recycled PU materials, after modification treatment, maintain excellent tensile and tear resistance, making them very suitable for the frequent use and wear of daily backpack products. Waterproof and Easy to Clean: Similar to traditional PU, recycled PU has good waterproof performance, making it highly valuable in outdoor backpacks and sports bags. In addition, its surface is easy to clean, facilitating daily maintenance. Diversity and Design Flexibility: Recycled PU can be customized in different thicknesses, textures, and colors, allowing for a variety of styles and design options, enriching the appearance choices for backpacks.   The Production Process of Recycled PU 1.Collection and Sorting: Producers collect waste PU from post-consumer or industrial waste and sort it. 2.Crushing and Melting: The sorted PU waste is crushed and then melted to be reshaped at high temperatures. 3.Filtering and Treatment: Chemical treatment is used to remove impurities and maintain the stable performance of the PU material. 4.Reshaping and Processing: Finally, the material is reshaped into films or fabrics for production, creating the recycled PU materials we are familiar with. This production method is more energy-saving and environmentally friendly than synthetic PU materials, and it also reduces the dependence on chemicals.   Why Choose Recycled PU? For brands and consumers who focus on environmental protection and social responsibility, recycled PU represents a forward-looking choice. It not only reduces material waste and environmental pollution but also provides a sustainable alternative to traditional materials. Synberry is well aware of the importance of environmental protection to the industry, and we are committed to continuously introducing more recycled PU materials into our future backpack products, making every backpack a contributor to the protection of the Earth's resources.

Traditional leather production significantly harms the environment, requiring large amounts of water and energy, and releasing harmful chemicals that pollute soil and water. The demand for livestock also leads to deforestation and biodiversity loss, worsening the ecological crisis. With growing global awareness of sustainability, finding eco-friendly alternatives has become essential. The innovative use of reusable materials like apple waste to create leather alternatives is particularly important. Recently, the fashion and leather industries have sought solutions to reduce their environmental impact. A notable advancement is converting apple waste into leather alternatives, which helps minimize waste and promotes sustainability in an industry criticized for resource-intensive practices. The Danish company Beyond Leather Materials has partnered with polymer producer Covestro to develop an innovative leather alternative made from apple waste generated during the production of apple juice and cider. From Waste to High-End Material Every year, approximately 4 million tons of waste are produced globally from apple juice and cider production. This waste is often viewed as a useless burden, ultimately discarded or burned, leading to significant resource waste and environmental pollution. However, Beyond Leather Materials has creatively transformed these previously discarded materials into an eco-friendly leather alternative—a new type of leather material—through innovative technology. They begin by filtering out fibers such as seeds and stems from the apple waste, which contain high levels of polymers. This is followed by a series of reactions to create a strong and flexible material, which is then combined with a textile base layer. Finally, a protective layer produced by Covestro is applied to the surface. Beyond Leather has positioned this material as a preferred new-generation option for various industries and applications, including the backpack industry and furniture sector. In the near future, this material may even be used in automotive interiors. At Synberry, we are always focused on sustainable development and environmental innovation. We are confident in this emerging material that transforms apple waste into leather alternatives and see its enormous potential in the backpack industry. In the future, we plan to explore the application of this eco-friendly material in our products, creating backpacks that are both stylish and sustainable, meeting the dual demands of modern consumers for environmental friendliness and high quality. Through these efforts, we hope to contribute to protecting the Earth while providing our customers with more innovative choices.
