Turning under-used biomass into useful biochar products

We develop pilot-led projects that connect biomass recovery with compost and soil products, mine rehabilitation and regional resource recovery.

About

A project-development and integration platform

TerraChar is a project-development and integration platform. We bring together feedstock assessment, logistics, technology selection, product testing and end-use trials to build credible biochar opportunities.

We start with two questions: what biomass can be reliably recovered, and who can use the resulting product? Each opportunity is developed around its own feedstock, site and customer requirements.

Two questions that drive every project

What biomass can be reliably recovered?

Who can use the resulting product?

Projects

Four development pathways

Our project themes represent distinct development pathways. Each requires its own evidence and pilot design.

Composter residues

Testing whether woody material that is difficult to compost can be converted into biochar for use in compost blends and soil products. Pilots assess preparation, product quality, operating reliability and customer acceptance.

Wood chips and timber residues

Exploring clean wood chips, offcuts, bark and other mill residues as potential feedstocks. Development starts with verifying supply, moisture, competing uses and delivered cost, then assessing suitable processing and potential heat integration.

Green waste and regional biomass

Assessing suitable council green waste and locally available clean woody residues. Pilots test collection, sorting, preparation and conversion, with products matched to local soil and rehabilitation applications.

Regional crop concepts

Investigating whether suitable arid or saline-land biomass could support future projects. Early demonstrations begin with verified existing biomass; purpose-grown crops require agronomic and supply validation.

Approach

Pilot first. Scale with evidence.

Our approach: frame the opportunity → verify feedstock → define the product → select technology → pilot → validate → scale.

We design the smallest practical pilot that answers the next investment decision. Testing covers conversion performance, product quality, emissions, reliability, logistics, end-use response and economics.

Each stage pairs evidence with engagement: landholders and feedstock owners confirm supply; host operators test integration; prospective customers assess products; relevant authorities clarify project requirements. Scale follows validated performance and credible commercial commitments.

Our commercial cases are tested without relying on carbon-credit revenue. Any carbon-removal opportunity is assessed separately against project-specific measurement and certification requirements.

Mine Rehabilitation and Invasive Species

Trial pathways for biochar in rehabilitation

We are developing trial pathways for biochar blends and manufactured growth media in mine rehabilitation. Field trials would measure vegetation establishment, soil-water behaviour and nutrient response against site-specific objectives.

Where appropriate, recovery of invasive woody biomass can form part of a legitimate control programme. Removal must include weed-safe handling, prevention of seed spread, follow-up treatment and monitoring to demonstrate net infestation reduction.

Mapping and remote sensing can help prioritise work and track vegetation change. Field verification and soil testing establish the performance evidence.

Biochar use, weed control and rehabilitation outcomes must each be demonstrated before wider deployment.

Vegetation establishment

Field trials measuring plant establishment against site-specific objectives.

Invasive species recovery

Weed-safe handling, seed spread prevention and follow-up monitoring.

Remote sensing

Mapping and remote sensing to prioritise work and track vegetation change.
