Kiln configurations
Retort chambers from 2.31 m³ to 9.24 m³, in containerised, mobile, standalone industrial, stainless steel and mild steel commercial builds.
Commercial & municipal
From biomass to regenerative enterprise
We size the kiln, model the economics before anyone commits capital, and build the offtake path so the char has somewhere to go. Waste stream in, working asset out.

Technology
Precision biochar systems, built for African conditions
Modular low-emission retort kilns designed to run on the feedstocks you already have, without depending on grid electricity. Deployed through our technical partnership with The Biochar Company Africa.
PROCESS
How they run
Syngas recirculation and self-sustaining heat generation cut fuel requirements. Wood vinegar is captured as a by-product rather than vented.
OUTPUT
Char to specification
Biochar is not generic. We tune temperature, residence time and post-handling to the end use, whether that is filtration media or a soil amendment.
Designed for purpose
Four chars, four jobs
The performance of biochar depends on the interaction between feedstock type, production temperature, residence time, moisture content and how it is handled after the burn. We optimise for the intended use case rather than producing one blend and hoping it suits everything.
- Water filtration — high adsorption capacity, microporosity, pollutant capture
- Soil regeneration — carbon stability, moisture retention, cation exchange, microbial habitat
- Livestock & compost — moisture management, odour suppression, compost stabilisation
- Air filtration — volatile compound adsorption, humidity control, odour removal
Feedstock
The problem is the raw material
Black, green and silver wattle are treated almost everywhere as a clearing cost. We treat them as an input, which changes the economics of clearing them.
- Black wattle (Acacia mearnsii)
- Green wattle
- Silver wattle (Acacia dealbata)
- Forestry residues and wood waste streams
- Dairy slurry blends and poultry litter
- Crop residues
Clearing invasive alien vegetation restores catchment hydrology and returns water to the system. The obstacle has never been the ecology — it is that clearing costs money and produces nothing but a burn pile.
Converting that biomass into biochar, animal feed supplements, renewable heat, compost and wood vinegar turns a cost centre into a supply chain, and gives landowners a reason to keep clearing after the grant money ends.
Services
What we actually do for clients
Most biochar projects fail on economics, not chemistry. We front-load the modelling so you know whether a project works before the kiln is on a truck.
01
Biomass valorisation
Biomass identification, harvest logistics, feedstock aggregation, processing and conversion, product development and route to market — the full chain, not one link of it.
02
Dynamic modelling
CapEx and OpEx, biomass availability, production efficiency, yield forecasting, revenue projections and sensitivity analysis, built around your feedstock rather than a generic template.
03
Carbon intelligence
Permanence projections, sequestration estimates, monitoring frameworks, verification support and MRV integration for organisations pursuing credits or reporting on ESG commitments.
04
Right-sizing kiln purchases
The most expensive mistake in this industry is buying too much kiln. We match system size to your actual feedstock volume, labour and burn cycle before you spend the capital.
05
Training & education
Operator training, knowledge transfer and ongoing support for your team, so the system keeps running once we are off site.
06
Advisory & offtake
Product commercialisation, carbon market positioning, investor readiness, feasibility development and partnership structuring.
Applied work
Catchment and stormwater filtration
Biochar gabions and socks at stream inlets, and biochar-amended reed beds upstream, intercept pollutants before they reach open water. It is a rapidly deployable intervention while long-term wastewater infrastructure is rehabilitated — not a replacement for it.
Knysna Lagoon proposal
Our proposal for the Knysna Lagoon targets nutrient loading, elevated E. coli and algal blooms entering through the Bongani, Bigai and Salt River catchments. The design pairs heavy-duty biochar gabions at the three main stream entrances with biochar-amended upstream reed beds.
The biochar is produced from invasive wattle cleared from the same catchment — roughly 11 hectares of dense black wattle a year — which restores catchment hydrology while supplying the filtration medium.
- 58 tonnes of biochar for initial installation
- 76 tonnes annually for replacement and maintenance
- Two 3.2 m³ retort kilns and a biomass-fired heat recovery system
- Floating litter traps and modular biochar gabions
- A water quality monitoring programme
- Approximately 20 direct green jobs
Field data from stormwater treatment trials using biochar media is available on request, along with the full executive summary of the Knysna proposal. Figures above are from the proposal as submitted; budgets are being finalised.
