Biochar & the Green Carbon Wallet: Turning Waste into Wealth and Climate Solutions

In the race against climate change, sustainable solutions must not only reduce emissions but also enhance soil health, support circular economies, and empower communities. One such multifaceted solution is biochar, a carbon-rich product derived from biomass and when integrated with AIROI INC’s Green Carbon Wallet, it becomes a powerful tool for climate action, traceability, and monetization through carbon credits.

What is Biochar?

Biochar is a stable, carbon-rich form of charcoal produced by heating organic biomass in a low-oxygen environment, a process known as pyrolysis. Unlike typical charcoal, which is used for fuel, biochar is primarily used as a soil amendment, offering environmental and agricultural benefits while sequestering carbon for hundreds to thousands of years.

Sources of Biomass for Biochar

Biochar can be made from a wide range of organic waste streams, making it both scalable and adaptable across geographies. The choice of feedstock influences the characteristics of the final biochar product.

Common Feedstock Types:

Agricultural Waste: Rice husks, sugarcane bagasse, corn cobs, coconut shells
Forestry Residue: Wood chips, sawdust, tree bark
Urban Organic Waste: Food waste, green waste, landscape trimmings
Livestock Waste: Poultry litter, cattle manure
Industrial By-products: Paper mill sludge, cotton gin trash

Each of these sources, when processed correctly, helps prevent methane emissions from decomposition and opens doors to carbon credit monetization.

How Biochar is Produced:

The production of biochar involves thermochemical decomposition of biomass under limited oxygen conditions. This ensures carbon remains trapped in the solid biochar rather than released as CO₂.

Key Production Methods:

Traditional Kilns

Low-cost, small-scale units (e.g., pit kilns or earth mounds)

Low efficiency and higher emissions

Improved Portable Kilns

Mobile, low-emission systems for rural applications

Batch Pyrolysis Units

Fixed reactors used for controlled pyrolysis

Suitable for small- to mid-scale operations

Continuous Pyrolysis Systems

Industrial-scale units offering high yields and efficiency

Enable waste heat recovery for co-generation

Gasification Units (with biochar by-product)

Generate energy while also producing biochar

AIROI’s Green Carbon Wallet enables traceability and documentation of the entire process from biomass collection to biochar production, testing, storage, and application ensuring transparency and accountability.

Applications of Biochar

Biochar’s versatility allows it to be applied across sectors, turning waste into value.
Agriculture

Enhances soil fertility by improving nutrient retention

Increases water holding capacity

Promotes microbial activity and root growth

Reduces dependency on chemical fertilizers

Livestock Farming

Used as a feed additive to reduce methane emissions

Applied as bedding material to control odors

Waste Management

Convert organic waste into stable carbon

Can be mixed with compost to improve efficiency

Construction & Industrial Use

Incorporated into concrete and asphalt to improve insulation

Used in activated carbon production

Water Filtration & Remediation:

Adsorbs heavy metals and toxins

Purifies wastewater and polluted soils

Benefits of Biochar

Environmental: Long-term carbon sequestration, methane reduction, soil restoration
Agricultural: Improved yield, nutrient use efficiency, resilience to drought
Economic: Value from waste, reduced input costs, additional revenue through carbon credits
Social: Job creation, rural income, gender-inclusive opportunities

By locking carbon in a solid form, biochar offers a negative emission solution, recognized by the IPCC as essential for limiting global warming to below 1.5°C.

Biochar & Carbon Credits: Monetizing Sustainability

Biochar projects offer a quantifiable, verifiable method of carbon sequestration, enabling them to earn carbon credits in both compliance and voluntary markets.

How Carbon Credits Work in Biochar:

Baseline Assessment: Determine emissions avoided through waste conversion
Carbon Sequestration: Calculate the amount of stable carbon in biochar
Co-benefits: Credits may include methane avoided from decomposing waste, fertilizer offsets, etc.
Monitoring & Verification: Requires robust data collection, testing, and third-party verification

Green Carbon Wallet: Enabling Transparency & Monetization

AIROI INC’s Green Carbon Wallet is a blockchain-powered platform that digitizes the entire carbon journey from project registration to issuance and sale of carbon credits ensuring trust, transparency, and traceability.

Key Features:

Digital MRV (Monitoring, Reporting, Verification): Tracks biomass sourcing, process data, biochar yield, and application
Blockchain Certification: Immutable records for registry, ownership, and carbon credit provenance
IoT Integration: Sensors can be installed to monitor temperature, emissions, and yields in real-time
AI Analytics: Estimate and optimize carbon credit potential across projects
Marketplace Access: Facilitates credit sales to buyers committed to net zero goals

Through this platform, biochar producers, whether farmers, cooperatives, or industrial units can monetize carbon credits, access climate finance, and contribute to Sustainable Development Goals (SDGs).

SDG Alignment

Biochar projects align with multiple UN SDGs, including:

SDG 2: Zero Hunger – improves soil productivity
SDG 6: Clean Water – supports water purification
SDG 7: Affordable Clean Energy – enables clean bioenergy
SDG 12: Responsible Consumption and Production
SDG 13: Climate Action – carbon sequestration
SDG 15: Life on Land – soil health and biodiversity
