Process engineering focus

Engineering anaerobic digestion plants for industrial organic residues

The engineering approach combines anaerobic digestion, biogas production, potential biomethane upgrading and the material recovery of digestate and nutrients. Detailed process solutions are available for the following feedstocks:

Engineering deliverables

Practical deliverables for investment, procurement and plant operation

The deliverables support technical due diligence, permitting and procurement, supplier coordination, construction, commissioning and subsequent plant operation.

Feasibility and investment decisions

Technical options, gas and energy potential, limitations, cost framework and project risks are compared transparently.

Design and tender documentation

Assumptions, material flows, interfaces, requirements and scopes of supply are documented clearly and verifiably.

Technically comparable bids

Clear specifications and evaluation criteria support supplier selection and reduce later change orders.

Schedule, cost and quality control

Decisions, open issues, schedules, costs and quality are systematically tracked and prioritised.

Acceptance, commissioning and performance verification

Inspections, defect resolution, trial operation and performance verification are prepared, documented and supported.

Stable and efficient plant operation

Operating concepts and training retain the technical knowledge required for process stability, safety and energy efficiency.

Project workflow

From data basis to plant commissioning

The workflow is adapted to new construction, plant expansion, conversion to biomethane, repowering or optimisation of an existing biogas plant.

01

Define project objectives & scope

Agree objectives, boundary conditions, project phase, responsibilities and required decisions.

02

Review feedstocks, data & risks

Assess organic residues, material flows, analyses, plant documentation, bids and project risks.

03

Develop plant concept & options

Design processes, prepare mass and energy balances, compare options and provide technical justification.

04

Support design, procurement & construction

Coordinate interfaces, schedules, quality, tendering, suppliers and construction execution.

05

Commission and hand over results

Structure tests, trial operation, performance verification, documentation, open issues and next steps.

Frequently asked questions

Frequently asked questions about biogas and biomethane engineering

Answers about engineering scope, feasibility studies, plant optimisation, organic residues and international project support.

What services are included in biogas plant engineering?

Depending on the project phase, the scope may include a feasibility study, feedstock assessment, mass and energy balances, process selection, preliminary sizing, tendering, project management, construction supervision, commissioning and plant optimisation.

When is a biogas feasibility study useful?

Before an investment decision, when introducing new feedstocks, expanding capacity, converting to biomethane or planning a repowering project. The study assesses technical feasibility, gas and energy potential, plant concept, cost framework and risks.

Can an existing biogas plant be technically optimised?

Yes. The assessment may cover process stability, feedstock mix, organic loading rate, retention time, energy consumption, heat utilisation, bottlenecks and options for capacity expansion.

Which organic residues are covered by the process solutions?

Focus areas include digestate, straw and lignocellulosic materials, bioethanol and brewery residues, starch and potato residues, as well as POME, palm-oil and sugarcane residues.

Is the engineering consultancy independent and international?

Yes. The consultancy is supplier-independent and can be provided as a defined work package or continuous project support. Project communication is available in German, English and Polish.

Project enquiry

Are you planning, reviewing or optimising a biogas or biomethane plant?

Briefly describe the project phase, material flows, existing plant and objectives. During the initial contact, we clarify the suitable work package and required documents.
