Activated biochar
Carbonised under a computer-controlled heat curve, then activated at close to three times the efficiency of the standard route. The result is a high-surface, low-variability carbon that performs the same way in the tenth container as in the first.

How it is made
01Feedstock selection and dryingCertified plantation eucalyptus from Paraguay and Brazil, with documented origin. Moisture is brought to target before the material enters the reactor.
02Computer-controlled pyrolysisThe heat curve is programmed for the feedstock and held through drying, devolatilisation and carbonisation. Temperature and residence time are logged for the batch record.
03C-fix controlFixed carbon is the parameter the process is steered towards, and it is verified analytically per batch rather than inferred from the burn.
04High-efficiency activationOur activation step develops close to three times the usable surface per tonne of feedstock compared with the standard process, which is where adsorption capacity comes from.
05Sizing and packingScreened to the agreed granulometry or milled to powder, then packed in big bags, sacks or loose bulk according to the order.
Applications
Soil amendmentStructure, water-holding capacity and cation exchange in degraded and sandy soils.
Fertilizer blendingCarbon carrier in organomineral and granulated blends, reducing nutrient leaching.
Microbial carrierPore structure that hosts inoculants and biological formulations in storage and in soil.
Animal bedding and housingAdsorbent in bedding and litter, for moisture and barn odour management.
Water and effluentFiltration media and adsorbent in effluent treatment and odour management.
Carbon removalStable carbon with a long residence time in soil, for programmes that require it.

Values are typical for standard production and are confirmed per batch on the certificate of analysis. Specifications can be adjusted against a firm volume commitment — send us your target and we will confirm feasibility before quoting.
How to read our specification
Fixed carbon is the share of stable carbon that remains once the volatiles have been driven off. The H/C molar ratio is the stability indicator carbon-removal buyers work with. Both are measured per batch and reported on the certificate of analysis. Where a value reads "to specification", the figure is agreed in the contract and confirmed on the COA.
Buyer questions
Can you hit a specific fixed-carbon target?
In most cases yes. Because the heat curve is programmed rather than judged by eye, we can steer production towards a target and confirm it analytically per batch. Send your target range with the enquiry and we will tell you before quoting whether it is within our window.
What does "three times the activation efficiency" mean in practice?
It refers to our activation step, which develops close to three times the usable surface from the same tonne of feedstock compared with the conventional route. For a buyer it means more adsorption capacity per tonne shipped — a better landed cost per unit of performance, not just per tonne.
Do you supply a certificate of analysis?
Yes, per batch, travelling with the shipment. We also keep a retained sample of each batch, so if anything is disputed on arrival it can be checked against the same material rather than against an argument.
What is the minimum order and how fast can you ship?
Twenty tonnes is the practical minimum for export pricing; sample quantities are available separately for qualified buyers. Lead time depends on granulometry, packing and port, and is confirmed in writing with the quotation.
