Rethinking biosolids for today’s changing regulations

Federal and state frameworks govern how biosolids are treated, disposed of, or reused. With evolving regulatory expectations and mounting scrutiny of traditional pathways like land application and landfills, engineered biochar offers a controlled, compliant alternative that transforms biosolids into a stable material through heat, not chemical additives.

Biochar is a carbon-rich product created through the thermal decomposition of organic waste.

By converting organic waste into biochar, we provide a sustainable solution that addresses emerging contaminants like PFAS, microplastics, and pharmaceuticals while providing remediation and construction material solutions and contributing to carbon sequestration.

Carbon Sequestration

Biochar provides durable carbon removal when land-applied, playing a significant role in the growing carbon economy.

Filtration media

Biochar captures metals, volatile organic compounds (VOCs), and PFAS, and supports circular treatment systems by reducing PFAS through thermal processing.

brownfields site remediation

Biochar sequesters metals and other contaminants in polluted soils, aiding in environmental cleanup.

Construction Materials Additive

Biochar derived from biosolids can be incorporated into construction materials, offering a consistent resource that diverts waste from landfills and supports a circular reuse system.

Frequently Asked Questions

How do biochar facilities handle air and odor emissions?

Biochar facilities are designed with advanced odor and emissions controls from the ground up. Facilities are sealed and maintained under negative pressure, routing all air through multi-stage filtration, scrubbers, biofilters, and particulate separators.

How much truck traffic does a biochar facility generate?

On most days, fewer than 12 trucks come and go from a biochar facility, fewer than at a typical grocery store. Each load is tracked from its source, ensuring transparency and accountability. This careful documentation minimizes the facility’s impact on the surrounding community.

Is biochar safe from PFAS and other contaminants?

Independent testing of biochar has shown non-detectable levels of PFAS, microplastics, and pharmaceutical residuals. A high-temperature gasification process is one of the few that can break down these contaminants, making the end product safe and usable.

What will the biochar be used for?

Biochar won’t be used on farms, and that’s by design. Instead, biochar will be used in construction materials like concrete and asphalt, and for environmental remediation. That means no risk to food or soil, and a powerful way to turn waste into a valuable product.

What makes Earthcare’s solution better than traditional landfilling?

Landfilling is Linear; our process is circular. Putting biosolids in landfills passes the problem downstream and increases long-term risk. Earthcare’s solution is breaking the cycle of contamination by turning waste into a carbon-rich product that’s clean, tested, and useful.

Researchers developed a new cleaning material by combining cauliflower leaf waste with a zinc-based framework to purify contaminated water. This eco-friendly catalyst successfully removes up to 92 percent of harmful industrial dyes from water in less than an hour. The system is powered by natural sunlight, making it a low-cost and sustainable alternative to traditional chemical water treatments. The cleaning material is highly durable and can be collected and used again for multiple cleaning cycles without losing its effectiveness.

A recent study in Biochar by Hua Jing and colleagues introduces a “scallop cage” nanoreactor that achieves a 97.53% removal efficiency for perfluorooctanoic acid. This innovative design uses algae-derived biochar to confine cleaning reactions, preventing the rapid deactivation of reactive species in water.

NoviqTech’s acquisition of Coralia establishes a large-scale biochar carbon removal operation in Australia. By securing two million tonnes of invasive biomass, the project addresses data center emissions and Great Barrier Reef health while generating high-integrity, verified carbon sequestration credits for institutional buyers.

A recent study in Biochar by Marianna Guagliano and colleagues shows that biochar carriers achieve a target loading of 23 milligrams of lysozyme per gram. The results demonstrate that intestinal release capacity increases by 50 to 53 percent compared to gastric conditions, enabling targeted delivery.

Guest blog by Nilanjana Banarjee, a carbon consultant specializing in biochar systems and early-stage carbon project planning, examines how biochar carbon projects overlook co-products, permanence, and early MRV integration, arguing that system-level accounting and conservative design choices are essential for long-term carbon credit credibility

A recent study in Biochar by Aycha Dalloul and colleagues demonstrates that magnetic modification increases biochar surface area by 52 percent and improves lead adsorption by 42 percent. These engineered materials achieve up to 85 percent immobilization of arsenic and cadmium in contaminated agricultural soils.
