CarbonMicro™ – The Next Generation Of Sustainable Carbon

Micronized Biochar for the Next Era of Green Innovation.

Wakefield’s CarbonMicro™ is a high-purity, micronized biocarbon engineered for advanced applications — from coatings to plastics, sustainable pigments, tires and energy storage materials. This is biochar reimagined for the modern materials industry.

What Is CarbonMicro™?

CarbonMicro™ is Wakefield’s engineered form of micronized biochar — a fine, high-surface-area carbon material derived from renewable biomass through controlled pyrolysis.

• Particle size range: 100 microns to <15 microns
• Carbon content: 80–92%
• Surface area: 200–400 m²/g
• Feedstock: Sustainably managed softwood

This process creates a clean, consistent carbon material that performs like traditional carbon black — but with a dramatically lower carbon footprint and carbon sequestration benefits.

Sustainable Replacement for Carbon Black

Traditional carbon black is derived from fossil fuels and accounts for millions of tons of CO₂ emissions annually. CarbonMicro delivers comparable performance with a 90–95% lower life cycle carbon¹ footprint.

Applications include:

• Plastics and polymers
• Coatings
• Rubber and tire compounds
• Battery anodes and related materials

By substituting petroleum-based carbon with CarbonMicro, manufacturers can meet sustainability goals while improving performance consistency and regulatory compliance.

Industry Application Spotlight
Sustainable Flooring Innovation

Where sustainability meets material performance.

A global flooring manufacturer is incorporating Wakefield’s CarbonMicro™ into the backing layer of tiles, replacing a portion of traditional, petroleum-based carbon black. This innovation significantly reduces the embodied carbon of each square foot of flooring while maintaining the performance, durability, and appearance that customers expect.

By substituting fossil-derived carbon with biochar-based CarbonMicro, the manufacturer transforms a standard product into a carbon-negative material that stores carbon for hundreds of years instead of releasing it. The micronized structure of CarbonMicro allows for smooth dispersion and stable physical properties — making it a seamless fit for high-volume production.

Result: The integration of CarbonMicro™ in flooring materials demonstrates how engineered biocarbon can align with LEED and EPD goals, helping global brands reduce emissions and lead the shift toward a circular, low-carbon materials economy.

   European Biochar Certificate (EBC) – “Carbon Footprint of Biochar” (2022 update)
   Demonstrates that producing 1 ton of biochar typically removes 2.5–3.5 tons of CO₂e from the atmosphere when derived from sustainably sourced biomass. In contrast, producing 1 ton of fossil carbon black emits roughly 2.4–2.8 tons of CO₂e. Net difference = roughly a 90–95% reduction in lifecycle CO₂e emissions.
   IEA Bioenergy Task 34 Report (2021) – Confirms that substituting fossil-carbon materials (like carbon black) with biogenic carbon (biochar, bio-graphite, etc.) yields 80–95% reductions in lifecycle CO₂e when full sequestration and renewable energy factors are included.

2. High-Temperature Pyrolysis → Higher Carbon Content
   As pyrolysis temperature rises (700–900 °C vs. 400–600 °C), the biochar’s fixed-carbon content increases while volatile matter decreases. This yields higher carbon purity, greater aromaticity, and improved conductivity.

   Micronization → Improved Conductive Network
   Reducing particle size below 50 µm increases surface contact area and electron pathway continuity, enhancing conductivity in composites, inks, and polymers.
