Plan the right project. Build it right. Run it responsibly.
Altpreneur connects feedstock, biology, engineering, construction and operations so critical decisions remain aligned from the first field survey to daily plant output.
Discuss your projectIntegrated service model
Choose a focused assignment—or one accountable delivery partner.
Our scope can begin with a feedstock assessment, feasibility study or design review; extend into EPC and turnkey execution; and continue through plant operations and management. The advantage is continuity: assumptions made during planning remain visible during procurement, construction, commissioning and operation.
Field intelligenceLaboratory evidenceProcurement controls
Feedstock identification & procurement
Feedstock is the operating business model—not a line in the DPR.
We assess what is actually available, when it is available, how quality varies, who controls it and what it costs after aggregation and transport. Representative samples are linked to laboratory findings and process suitability before the feed mix and plant capacity are frozen.
- Catchment and competitionVillage, mill, dairy, farm and organic-waste sources mapped against existing uses.
- Commercial architectureSupplier mix, contracts, price bands, incentives, aggregation centres and fallback sources.
- Daily operating controlsWeighment, sampling, rejection criteria, inventory, traceability and quality reconciliation.
Consulting scope
Decisions supported from opportunity to investment.
Each work package concludes with defined assumptions, findings, risks and recommended actions.
Feedstock identification
Catchment mapping by quantity, seasonality, composition, collection radius, competing use and delivered cost.
Procurement strategy
Supplier segmentation, aggregation model, pricing logic, quality acceptance, logistics and buffer planning.
Feasibility & DPR
Mass balance, process concept, capacity selection, CAPEX/OPEX basis, financial model, risks and implementation plan.
Engineering advisory
Technology comparison, process flow, equipment sizing, design reviews and technical bid evaluation.
Project coordination
Documentation, schedule, vendor interfaces, stakeholder readiness and gas-quality / offtake alignment.
EPC & turnkey execution
A connected scope from design basis to performance validation.
We manage the interfaces between process, civil, mechanical, electrical, automation, vendors and the construction site.

Operations & plant management
We can take responsibility for the day-to-day plant operation.
Altpreneur undertakes structured O&M assignments focused on stable gas output, safe work, equipment availability, cost control and transparent reporting. The operating plan is tailored to the plant technology, feedstock mix, installed systems and performance baseline.
Plant manpower
Recruitment support, shift roster, responsibility matrix, SOPs, training and daily supervision.
Feedstock operations
Receipt planning, weighment, sampling, recipe control, pre-treatment and feeding discipline.
Biological control
OLR, retention time, temperature, pH, alkalinity, VFA trends, gas yield and corrective action.
Asset reliability
Preventive maintenance, condition checks, lubrication, spares, breakdown coordination and uptime tracking.
Gas quality & safety
CH₄, CO₂, H₂S and moisture tracking, safety interlocks, permits, drills and compliance records.
MIS & optimisation
Production, consumption, downtime, cost, inventory and performance reporting with improvement actions.
Management rhythm
Shift log and daily MIS · laboratory trend review · weekly maintenance plan · consumables and spares control · monthly performance review
