Carbon, nutrients and microbes, in one technology.
At the core of every XEN product is the Regenerative Carbon Matrix: an activated long-chain carbon structure that feeds microbes, carries nutrients to the root zone and holds water, so carbon, nutrition and biology work as one system.
A biological carbon engine
Three interacting layers unlock, activate and retain.
Lignocellulose deconstruction
Specialised microbial consortia break down lignin, cellulose and hemicellulose, releasing carbon and nutrients that would otherwise stay locked in slowly decomposing biomass.
Complete nutrition + microbes
Decomposers, nutrient mobilisers, carbon-fixing bacteria and chemoautotrophs multiply, supported by 109 herbal extracts inspired by Vriksha Ayurveda.
Regenerative carbon matrix
A porous carbon matrix holds nutrients and water, gives microbes a habitat and exchanges nutrients with the root zone as the plant needs them.

Three kinds of carbon
Carbon that is designed, not incidental.
Most organic inputs contain carbon. XEN designs it, integrating three carbon pools that each do a different job.
Feeds microbes now
Readily available energy that starts microbial activity immediately after application.
Holds water & nutrients
Humic and fulvic substances chelate nutrients and reduce their loss from the root zone.
Restores soil long-term
Durable carbon that builds soil organic matter, structure and water-holding capacity over seasons.
Inside the matrix
Activated long-chain carbon: the core of soil regeneration.
Stabilises organic carbon and raises soil organic carbon.
Cellulose, glucose and fructose feed every microbial strain so they thrive together instead of competing.
Humic and fulvic substances chelate nutrients and improve availability.
A porous home for a diverse, functional microbial consortium.
Bacteria bond with soil moisture to anchor carbon in the root zone and improve water holding.
Supports microbial respiration and speeds up nutrient transformation.
Chelates and carries macro and micronutrients to the root zone.
Better root growth, nutrient uptake and rhizosphere vitality.
Five engineering pillars
Science engineered. Nature enhanced. Value unlocked.

Carbovardhak · lab-tested fertility stack
The numbers behind the matrix.
Microbial consortium
Functional groups that work together.
Anaerobic-to-aerobic adaptation. Microbes are acclimatised in a controlled hybrid environment so they survive and stay active in open soil.
Microbial coexistence technology. A carbon food matrix of cellulose, glucose and fructose prevents competition between strains.
| Functional group | Examples | Role |
|---|---|---|
| Cellulose degraders | Cellulolytic bacteria | Accelerate decomposition |
| Lignin degraders | Ligninolytic microbes | Break recalcitrant biomass |
| Nutrient mobilisers | PSB, KSB, KMB | Improve P & K availability |
| Nitrogen fixers | Azotobacter, Acetobacter | Biological N contribution |
| Biocontrol & roots | Trichoderma, Pseudomonas, Mycorrhiza | Plant resilience, root uptake |
Enrichment process
How Carbovardhak turns waste into wealth.
The same three biological stages, activate, multiply and stabilise, run at farm scale and at industrial scale. Choose a protocol.
Dilute and mix the first half of the dose uniformly through the dung. Cover and rest. Decomposers start on the lignocellulose.
Turn and aerate the batch, apply the next quarter, remix and cover. Carbon-fixing and nutrient-mobilising microbes multiply.
Apply the final quarter, turn uniformly and verify readiness: brownish-black, about 40% moisture, no odour.
Roughly 1,000 kg/acre of enriched manure replaces about 3,000 kg of ordinary FOM, with 67% less handling.
Typical dose: 50–100 L Carbovardhak per tonne of cattle dung (500 kg FOM + 35 L Carbovardhak + 35 L water → 570 kg enriched output). Paddy straw and dung compost runs 20–35 days with three turnings.
100 L Jivamrit or raw LFOM + 10 L Carbovardhak → 110 L enriched output.
Stir for about an hour a day for 7–10 days while microbes multiply.
Check odour, consistency and settling before use.
About 500 L/acre of enriched LFOM replaces roughly 1,500 L of untreated slurry, through drip, drench or irrigation channels.
Working range for liquid enrichment is 5–15%, subject to site validation.
The PLC meters the batch and injects half the dose via pump → injection quill → static mixer → enrichment tank.
Interlocks verified, 25% injected, intensive mixing; programmed intermittent mixing between dose days.
Last quarter injected with intensive homogenisation. Tank stays closed and safely vented.
Final mixing, closed sampling and lab checks. Only approved batches are filtered, stored and dispatched.

Total dose = LFOM batch × 10%
Calculated from the volume actually transferred into the enrichment tank, not digester feed or plant throughput. Confirm dose and residence time in a controlled pilot before sizing equipment.

Carbon-Centric Digestate Valorisation Platform™
One CBG plant. Two value engines.
A CBG plant is both an energy facility and an organic-resource processing facility. Energy is recovered as gas; carbon and nutrients continue through the digestate. The second value chain begins after digestion, not after disposal.
A · Energy ledger
Biogas → CBG
gas volume × methane recovery × CBG realisation
Primary plant revenue. XEN does not touch this process.
B · Digestate ledger
FOM + LFOM → premium fertiliser
FOM/LFOM quantity × verified quality × market offtake
More than 90% of the biomass leaving a digester comes out as digestate. Today it is mostly sold as low-value bulk manure.
The 90% opportunity
Over 90% of digestate’s potential value is untapped.
Raw digestate has nutrients in low-available form, unstable carbon, inactive microbes, odour and pathogens, and gives farmers inconsistent results. Carbovardhak Flow activates that hidden potential and turns it into a new profit centre for the plant.
Digestate Engineering™ process
From residue to premium regenerative fertiliser.
Optional size reduction, moisture adjustment, homogenisation.
Biogas production runs unchanged.
Solid FOM and liquid LFOM separated.
Characterised: moisture, TS, pH, EC, carbon, NPK.
By volume for LFOM, by weight for FOM.
Uniform distribution of matrix, microbes and nutrients.
48 hours to 10 days (21-day cycle for industrial LFOM).
High-carbon, nutrient-rich, microbially alive and QC-released.
Quality-control framework
One batch. One auditable decision.
Incoming FOM / LFOM
During enrichment
Final enriched product
Every batch carries a Digital Batch Passport: batch number, date and shift, feedstock mix, digestate and Carbovardhak quantities, mixing and retention, operator log, sample ID, lab result and release status.
Retrofit · downstream by design
Biogas production stays exactly as it is.
- No addition to the digesterNo interference with digestion or methanogenesis.
- Starts after separationSeparate FOM and LFOM modules, matched to daily digestate output.
- Metered and recordedCovered processing, drainage control, SCADA/PLC integration where feasible.
- Phased rolloutPilot batch → validated SOP → modular retrofit → continuous operation.
