EPC Solutions

CBG plants engineered for the way they will operate.

From site diligence to commissioning, XEMX brings civil execution, process technology, and system integration into one defined EPC scope, with feedstock and operating support where required.

Our Approach

Engineering Grounded in Operating Experience.

No two feedstocks or sites are identical. We define the plant around raw-material characteristics, gas specification, utilities, logistics, and the owner’s operating model, drawing on trials, plant feedback, and technology partnerships.

Civil engineering stays in-house. Foundations, tanks, buildings, drainage, roads, utilities, and feedstock-handling infrastructure are coordinated with mechanical, electrical, instrumentation, and process work against one integrated schedule.

How We Deliver

A Clear Path From Definition to Handover

Scope, responsibilities, schedule, and the performance framework are agreed for each project.

Define the Project

Map and test feedstock; review land, water, power, access, logistics, and buyer requirements. Select pre-treatment, digester design, mixing, purification, compression, and controls around those inputs.

Diligence · Design Basis · Process Selection

Build & Integrate

Translate the design into civil, mechanical, electrical, and instrumentation scope. Coordinate procurement, site works, installation, piping, cabling, automation, and system integration.

Civil Works · Procurement · Integration

Commission & Stabilize

Ramp up digester biology, tune gas upgrading, and test performance. Prepare operating procedures and train the owner team through start-up and handover.

Feedstock Services That Support the Plant

Feedstock support can extend the EPC engagement into the recurring supply system required to keep the digester fed.

  • Map seasonal volumes, competing uses, collection radius, and delivered cost
  • Build sourcing relationships with growers, mills, poultry farms, and aggregators
  • Plan storage, preparation, quality checks, backup supply, and daily scheduling
  • Support Napier grass and energy cane cultivation, irrigation, harvesting, and delivery where suitable

We Stay Beyond Commissioning

XEMX can remain involved through stabilization and ongoing operations and maintenance, with a support scope matched to the owner’s needs.

  • Loading plans, digester health, biology stabilization, and troubleshooting
  • Daily operating routines, gas-quality monitoring, and utility management
  • Preventive maintenance, critical spares, and vendor-service coordination
  • Feedstock blending, methane recovery, power consumption, and performance reporting
