Biochar Carbon for Stormwater

Transforming stormwater management with biochar

Stormwater runoff contains a variety of environmental contaminants that pose a growing threat to water quality and ecosystem health. These contaminants can include heavy metals, petroleum hydrocarbons, per- and polyfluoroalkyl substances (PFAS) and excess nutrients. At Myno Carbon, we offer biochar—a sustainable, versatile, and cost-effective tool recognized as a Best Management Practice (BMP) for comprehensive stormwater management.

Biochar is not just a material—it’s a tool for change. Whether you are retrofitting stormwater infrastructure, designing green roofs, or implementing urban soil restoration, biochar offers the versatility and effectiveness you need to achieve your goals sustainably.

More about biochar

The biochar advantage: a swiss army knife for stormwater challenges

Stormwater runoff is a growing issue, leading to contaminated waterways and ecosystem degradation, biochar is uniquely positioned to address these challenges

Exceptional filtration properties

Biochar’s porous structure and cation exchange capacity adsorbs contaminants including heavy metals, petroleum hydrocarbons, longcarbon-chain per- and polyfluoroalkyl substances (PFAS) and excess nutrients such as nitrogen and phosphorus, reducing their impact on water bodies.

Enhanced water retention and infiltration

By increasing soil permeability and reducing bulk density, biochar helps manage water flow during heavy rains, reducing overall runoff volumes.

Microbial habitat creation

Biochar supports beneficial microbial communities, which break down certain organic pollutants, further enhancing water quality.

Real-world impact: proven applications of biochar

Biochar’s effectiveness in stormwater management has been validated through numerous projects worldwide

Urban soil restoration

In urban environments, compacted soils lead to excess runoff and reduced water quality. Biochar-amended soils improve infiltration rates, mitigate erosion, and enhance the overall resilience of green spaces.

Biochar-enhanced bioretention systems

Adding biochar to bioretention media improves the removal of pollutants like suspended solids, heavy metals, and phosphorus. Research shows that biochar can increase nitrogen removal rates by up to 55%, outperforming traditional bioretention materials.

Roadway and infrastructure improvements

Biochar-amended roadway soils effectively reduce runoff and pollutant loads, offering scalable solutions for municipalities.

A sustainable solution with tangible benefits

Biochar’s role in stormwater management goes beyond filtration—it addresses broader environmental and operational goals

Climate Mitigation
Each unit of biochar sequesters roughly two units of CO₂ equivalent, contributing to global climate targets.

Economic Efficiency
Biochar provides a cost-effective alternative to activated carbon and other filtration materials, reducing upfront and long-term operational costs for stormwater infrastructure.

Regulatory Compliance
Biochar is a recognized Best Management Practice for stormwater filtration, helping municipalities and businesses meet standards while improving environmental outcomes. Numerous states, including Washington, California, and Minnesota, include biochar as a BMP for stormwater.
