Structured Solutions for Complex Environments

Protecting your capital investment requires independent, unbiased expertise. As your Owner’s Engineer, Methagenix acts as your technical representative throughout project development, procurement, construction, and handover—ensuring contractors deliver high-performing, bankable biogas assets on spec and on budget.

• Feasibility & Due Diligence: Comprehensive review of proposed plant designs, technology selections, feedstock contracts, and financial yield models for developers and investors.

• EPC Contractor & Procurement Oversight: Verifying engineering specifications, reviewing equipment quality, and ensuring compliance with international environmental and safety standards.

• Design Validation & Risk Mitigation: Rigorous technical audits of biological sizing, mixing dynamics, heating loops, and gas conditioning pathways before construction begins.

• Construction & Milestone Quality Audits: Independent on-site inspections to verify installation quality, timeline compliance, and performance guarantees prior to contractor sign-off.

When off-the-shelf equipment no longer meets your operational goals, we re-engineer existing biogas assets for higher capacity, lower parasitic load, and new substrate integration.

• Substrate Pre-Treatment Retrofits: Integration of mechanical, thermal, or enzymatic pre-treatment to break down complex biomass.

• Agitation & Heating System Redesigns: Replacing underperforming mixers and heat exchangers with high-efficiency solutions.

• Gas Upgrading Integration: Preparing biological outputs for RNG / biomethane grid injection or Bio-LNG conversion.

The transition from construction completion to stable biological operation is the most critical phase in a plant's lifecycle. We provide hands-on, on-site commissioning to safely build up methanogenic populations and ramp output to 100% capacity seamlessly.

• Inoculum Selection & Seeding Strategy: Sourcing and managing high-quality biological starter cultures for optimal bacterial establishment.

• Controlled Ramp-Up Protocols: Step-by-step loading rate increases designed to build buffering capacity and avoid early-stage VFA spikes.

• System Calibration & Performance Testing: Verifying heat distribution, mixing regimes, and gas cleanup integration under real operating conditions to hand over a fully optimized asset.

Foaming in digesters can cause catastrophic operational downtime, substrate loss, structural damage, and severe gas line blockages. We deliver rapid response protocols to knock down foam instantly and stabilize the underlying biological trigger.

• Emergency Foam Mitigation: Immediate deployment of specialized anti-foaming agents tailored to your digester's specific biochemistry.

• Root-Cause Diagnostics: Rapid identification of foaming drivers, including filamentous bacteria overgrowth, surface-active protein spikes, rapid organic loading increases, or mixing imbalances.

• Long-Term Foam Prevention: Re-balancing operational parameters and dosing strategies to eliminate recurring foam events permanently.

While remote monitoring is powerful, nothing replaces boots on the ground. Our senior biochemical engineers fly directly to your facility anywhere in the world to conduct deep-dive operational audits.

• Comprehensive Plant Audits: Full evaluation of biological health, substrate handling, heating loops, and gas management systems.

• Operator Training & SOP Development: Hands-on training for local operational teams to improve daily sampling, testing accuracy, and preventative care.

• Troubleshooting & Bottleneck Removal: Identifying physical, electrical, and biological limitations constraining overall plant throughput.

Prevent costly shutdowns before they begin. Our retainer services offer regular lab testing, trend analysis, and early-warning alerts for plant managers.

• Routine Parameter Panels: Regular evaluation of FOS/TAC, total VFAs, alkalinity, ammonium/ammonia, and dry matter content.

• Trace Element & Heavy Metal Audits: Preventing micronutrient deficiencies or toxic accumulation over time.

• Data-Driven Reporting: Actionable insights delivered straight to your operations team with clear instructions.

Operating at capacity isn't enough—your digester should be operating at peak financial efficiency. We fine-tune physical, chemical, and biological variables to increase methane production while lowering operating expenditure.

• Micronutrient & Trace Element Balancing: Correcting enzymatic bottlenecks with targeted dosing strategies.

• Organic Loading Rate (OLR) Optimisation: Safely pushing throughput limits without risking volatile acid accumulation.

• Acidification Recovery: Precision dosing of alkaline agents and biological inoculants to restore pH and methanogen activity during souring events.

Your plant is only as productive as the fuel you feed it. We provide comprehensive analytical characterisation to evaluate biogas yield potential, substrate compatibility, and inhibition risks before you feed your digester.

• Biomethane Potential (BMP) Testing: Precise measurement of maximum theoretical methane yield per tonne.

• Nutritional Profiling: Moisture, Volatile Solids (VS), Carbon-to-Nitrogen (C:N) ratios, and volatile fatty acid (VFA) composition.

• Inhibition Screening: Early detection of toxic loads, high ammonia, heavy metals, or organic contaminants.
