Companies are looking for leather alternatives that are as durable and tactile as the original. The solutions are driven by science and powered by nature.
Sustainability Drives The Change
Leather has accompanied humanity for millennia thanks to its versatility and durability. However, with over 20 billion square feet of leather produced annually, animal farming and leather production are responsible for increasing greenhouse gas emissions and deforestation.
Plastic leathers have been a longstanding vegan leather alternative; however, concerns around their petrochemical feedstocks, disposal, and microplastic production are beginning to outweigh their low costs for some companies. With sustainability-focused projects on the rise across many sectors, newer types of leather, including mycelium, plant-based, microbial, and lab-grown, are starting to emerge as more environmentally friendly options.
The tech research company IDTechEX has analysed the market, its key players and the pros and cons of the current alternatives with a forecast for the next decade.
Mushroom Mat Leather
Mycelium is emerging as a promising leather alternative thanks to its dense, mat-like growth structure, which can be processed to mimic the look and feel of animal leather. It decomposes easily, requires minimal water, and does not compete for agricultural land, positioning it as an environmentally attractive option.
According to IDTechEx, mycelium leather has the potential to be cost-effective in the long term, benefiting from low-cost feedstocks and opportunities for scalability and automation. However, pricing concerns persist due to the high capital expenditure required to establish and maintain growth facilities. These facilities must be sterile and climate-controlled, adding complexity and cost. Moreover, the current manufacturing infrastructures are not well-aligned with mycelium production, necessitating additional investment to adapt or develop compatible processes.
Plant-Based Byproducts
Plant-based leathers are derived from a wide range of natural sources and industrial byproducts, often blended with plastics to achieve the desirable leather-like properties. As a result, their composition can vary significantly across different types. Depending on the plastic content, many of these materials can decompose successfully, and their production tends to be relatively sustainable and cost-effective, with lower environmental impacts, such as reduced CO₂ emissions and water consumption. A key advantage is their compatibility with existing leather manufacturing infrastructure, which eases the transition for producers.
IDTechEx notes that plant-based leathers may not yet fully replicate traditional leather's aesthetic and tactile qualities, presenting a potential trade-off between sustainability and consumer expectations around performance and appearance.
Microbial Sheets And Lab-Grown Animal Cells
Microbial leather is produced using agricultural and industrial waste as feedstocks, which microbes convert into cellulose, collagen, or other biopolymers. These materials are then grown into sheets that can be processed to resemble conventional leather.
While microbial leather typically uses little to no fossil-based plastic, some formulations still incorporate synthetic components to enhance the performance. As a result, its compostability and biodegradability depend on the specific blend of materials. When minimal or no plastic is used, microbial leather offers a strong sustainability advantage.
Lab-grown leather, by contrast, is cultivated from animal cells to replicate the composition of traditional leather without the need for livestock slaughter. It offers the potential to tailor production volumes precisely, reducing material waste. However, this approach faces major challenges. The production process is highly complex and energy-intensive, requiring significant inputs of water, energy, and chemicals, particularly in post-processing. As a result, lab-grown leather is likely to remain prohibitively expensive for mainstream applications. Its most viable use case may lie in niche markets, such as high-end or exotic leather products, where unique material properties and ethical sourcing justify the premium.
What Is The Most Promising Alternative To Leather: The Forecasts
While some options are more cost-effective than others, with mycelium and microbial leathers being favourites within the industry, IDTechEx expects the vegan bio-based leather market as a whole to grow at a CAGR of 37.4% up to 2034. The popularity of these new materials is expected to gain traction among consumers and a wider platform of brands that shift towards prioritising sustainability goals.
