Direct Carbon Sequestration

What's included

Every capability below runs through SYNE Carbon's seeker-provider network, with SYNE's own advisory available end-to-end.

Enhanced Rock Weathering (ERW)

Crushed silicate rock applied to agricultural or industrial land, accelerating natural carbon mineralisation while delivering soil health co-benefits.

Enhanced Rock Weathering Carbon Removal

Applies crushed silicate rock to land, accelerating natural mineral weathering to remove atmospheric CO2.

Agricultural Mineralisation

Deploys ERW specifically across farmland, combining carbon removal with soil health co-benefits.

Industrial Land Mineralisation

Applies ERW to industrial land not used for agriculture, focused purely on the removal pathway.

Mine Waste Carbon Mineralisation

Uses mine tailings - already crushed and exposed - as the substrate for accelerated carbon mineralisation.

Rock-Based Carbon Credit

Structures verified ERW removal tonnes into a tradeable carbon credit.

In-Situ Mineralisation

Direct mineralisation of CO2 into stable rock formations, explored particularly for mining and industrial site applications.

Geological Carbon Mineralisation

Injects CO2 into suitable rock formations, converting it into stable mineral form underground.

CO₂ Storage & Mineralisation

Combines geological CO2 storage with active mineralisation for permanent removal.

Industrial Carbon Storage

Applies in-situ mineralisation to CO2 captured from an industrial process on the same or nearby site.

Mine Site Carbon Storage

Uses existing mine geology and infrastructure as a host site for CO2 mineralisation.

Permanent Carbon Removal

Focuses specifically on removal pathways with multi-century to permanent storage duration.

Agri-Enabled Decarbonisation

ERW, biochar and regenerative agriculture practices deployed together as a single farmer-facing program, not three separate initiatives.

Regenerative Agriculture Carbon

Applies regenerative practices across farmland to rebuild soil organic carbon while maintaining yield.

Farm Carbon Farming

Structures carbon removal as a direct, verifiable revenue line for the farm business.

Soil Carbon Enhancement

Measures and credits soil organic carbon gains from changed farm management practices.

ERW + Biochar Integrated Carbon

Deploys ERW and biochar together on the same land as one combined removal program.

Climate-Smart Agriculture

Combines carbon removal with resilience-focused farming practices suited to a changing climate.

Agricultural Carbon Credit Programme

Structures a multi-farmer program into a single, verifiable carbon credit issuance pathway.

Biochar

Biochar production and land application, sequestering carbon while improving soil water retention and fertility.

Biomass-to-Biochar Carbon Removal

Pyrolyses biomass into biochar, locking carbon that would otherwise decompose and release as CO2.

Waste-to-Biochar

Converts suitable waste biomass into biochar rather than sending it to landfill or open burning.

Agricultural Biochar Application

Applies biochar to farmland, combining carbon storage with soil fertility and water retention benefits.

Biochar Soil Carbon

Measures and credits the long-term soil carbon storage delivered by biochar application.

Biochar Carbon Credit

Structures verified biochar carbon storage into a tradeable removal credit.

Long-Term Carbon Storage

Focuses on biochar's multi-decade to century-scale storage stability as the basis for credit issuance.

Methodology & PDD Advisory

SYNE's own advisory on methodology selection and Project Design Document development, aligned to the standard the project will be verified against.

Carbon Methodology Selection

Advises on which carbon methodology actually fits a project's specific removal or avoidance pathway.

Carbon Standard Alignment

Aligns a project to the requirements of the specific carbon registry and standard it will be verified against.

Baseline & Additionality Assessment

Establishes the counterfactual baseline and demonstrates that the project's impact is genuinely additional.

Project Design Document (PDD) Development

Develops the formal PDD required before a project can proceed to validation.

Validation & Verification Preparation

Prepares the evidence package a third-party validator or verifier will actually need to review.

Carbon Credit Certification Support

Supports a project through to formal credit certification and issuance under the selected standard.

Part of SYNE Carbon

One of four enablement pillars, one seeker-provider network.

Direct Carbon Sequestration is one of four physical domains SYNE Carbon connects seekers and providers across - see the full ecosystem, case studies and the Vivent ERW spotlight on the main SYNE Carbon page.

Project approach

Nature-based, technology-based, or a hybrid of both.

Every project on this page can be delivered through any of these three approaches, matched to what actually suits the site.

Nature-Based

Working with existing land and ecosystems rather than new industrial infrastructure.

Explore Nature-Based

Technology-Based

Purpose-built infrastructure and process engineering for engineered outcomes.

Explore Technology-Based

Hybrid

Technology-enabled processes applied at nature-based scale, combining both approaches.

Explore Hybrid
Partner network

Deliver projects through SYNE Carbon.

Implementation partners and technology providers in Enhanced Rock Weathering, in-situ mineralisation, agri-enabled decarbonisation and biochar can join SYNE Carbon's partner network to get matched with seekers actively looking for proven delivery capability - vetted once, then visible to every relevant project.
