Biochar-Graphite Market to Double by 2035
The global market for biochar-based graphite is projected to grow from $321 million in 2025 to $629 million by 2035, expanding at a 13.5% compound annual growth rate. A new report attributes this growth to rising demand for sustainable materials in EV batteries and lightweight industrial components. This trend signals an opportunity for startups focused on advanced materials and industrial decarbonization.
- Biochar is a stable, carbon-rich material produced from biomass (such as wood or agricultural waste) through a process called pyrolysis, which involves heating in a low-oxygen environment. This process creates a porous structure ideal for various applications, including as a replacement for fossil carbon in industrial manufacturing. - The traditional graphite market, valued at over $22.9 billion in 2024, is split between natural and synthetic types. Natural graphite is mined, with China supplying 65-70% of the world's demand, while synthetic graphite is a more expensive and energy-intensive petroleum byproduct favored for its uniformity in EV batteries. - In lithium-ion batteries, graphite is the largest single component, making up as much as 50% of the battery's weight and serving as the primary anode material. The surging demand from the EV and energy storage sectors is a primary driver for seeking sustainable, high-performance alternatives like biochar-based graphite. - New Zealand-based startup CarbonScape, which recently raised $18 million, is commercializing a "biographite" made from forestry by-products. The company claims its product is carbon-negative and could reduce a battery's carbon footprint by nearly a third. - Beyond batteries, biochar has established applications in agriculture for improving soil fertility and water retention and is being explored as a sustainable substitute for coal and coke in steelmaking. Its properties can be tailored based on the feedstock and production process for uses ranging from water filtration to an additive in cement. - In Turkey, several startups are active in the advanced materials and industrial decarbonization space, including Biolive (bioplastics from olive waste) and Sumatrix Biotech (hydrogel materials from waste). The country recently launched the Türkiye Industrial Decarbonisation Investment Platform (TIDIP) with the EBRD, aiming to deploy €5 billion to decarbonize sectors like steel, cement, and aluminum. - Silicon-based anodes are another major alternative to graphite, with startups like Group14 and Sila Nanotechnologies leading development. While silicon offers significantly higher energy density, it has historically faced challenges with stability and cycle life, though recent breakthroughs are bringing it closer to commercial scale.
