London Brewery Innovates with Beer Grain-Based Leather Alternative

In an innovative approach to sustainability, a London-based brewery and a biomaterials lab are collaborating to transform spent grain from beer production into an eco-friendly leather alternative called “New Grain.” This process not only diverts waste from landfills but also offers a promising solution to the environmental impact associated with traditional leather production, including the tanning process. By altering the beer grain type, such as stout, the final product can achieve a range of colors and textures, akin to natural leather. This new material is expected to be more affordable than conventional leather, leveraging the low cost of feedstock from breweries. The developers are optimistic about scaling production and envision this alternative material entering both luxury and mainstream markets soon.

• Spent grain from beer production is repurposed to create a sustainable leather alternative named “New Grain.”
• The material is produced without using animals or plastics, addressing environmental concerns associated with traditional leather.
• An alkaline solution extracts protein from the grain, which then undergoes a transformation process to develop texture and strength similar to natural leather.
• Different types of beer grains lead to variations in the color and texture of the final product, allowing for customization.
• The environmental impact of leather production, especially the tanning process, is mitigated by exploring natural coloring agents and dyes.
• The creators are investigating ways to scale production and make the material more cost-effective than traditional leather and plastic leather alternatives.
• Initial product offerings are expected to target a small client base before expanding into luxury and eventually more accessible markets.
• The project benefits from the low cost of feedstock, as breweries often dispose of spent grain at minimal or no cost.
