Biogas Plants
Bigadan designs, builds & operates tailored modular biogas systems with cutting-edge technology ensuring a modern, efficient & profitable facilities.
Modular, flexible and efficient
Bigadan's modular process systems have been in use for decades and our we continue to improve them based on experiences from our own facilities — and close collaboration with customers. Our systems come in fixed designs and are scaled in modules ensuring high quality and a more efficient design, procurement, and construction period.
Our designs ensure a stable and reliable operation of the entire facility, as all systems have been tested for control, durability, and service.
Three distinct plant concepts
How we buildOur Biogas Plants are based on multiple proven components for the different plant concepts that all interact in the creation of efficient biogas production.

We’re continuously improving
Bigadan LabsOur proven biogas concept continually evolves thanks to close collaborations with clients and hands-on plant operations. With both mobile and onsite test laboratories, we explore new biomass potentials for biogas yield. As we discover new challenges, we merge our experience with trusted supplier expertise — all in order to achieve cost-effectiveness.
The benefits of a modular approach
Efficiency
Our standardized, module-based design facilitates lower construction and installation costs.
Swift Implementation
Typically, from the initial groundbreaking to plant commissioning, the timeline is usually around 12 months, depending on the project's scale.
Future Expansion
The modular nature of our plants means they can be easily expanded or modernised to meet growing demands or new technological opportunities.
Quality Assurance
Our long-standing relationships with primary suppliers ensure timely delivery and the high-quality standards our clients expect from us.

How we collaborate
01: Turnkey plants
When it comes to large-scale biogas systems, Bigadan offers comprehensive turnkey solutions. We take care of every phase — from detailed project planning to the complete delivery of your facility, from initiating operations to staff training. Our partners benefit from a streamlined construction phase, ensuring timely project completion and high operational efficiency.
02: Plant contracting
For projects where our clients handle the construction and often choose their suppliers, we step in to provide specialized expertise. We can contribute to various aspects of the project — detailed design of the entire facility, full equipment and process machinery, control systems like SCADA, construction and site management, commissioning, staff training, or even taking full responsibility for the operational process.
03: Ownership and operations
We own, co-own and operate many biogas facilities all over the globe. Few in the biogas industry boast as much operational experience as Bigadan, which gives you peace of mind — and operations. Our extensive knowledge and understanding of the daily challenges in biogas aids us in both new and existing partnerships.
04: Modernisation and expansion
Our offerings for existing plants encompass renovating current process tanks and equipment, expanding biogas systems with features like gas purification systems, heat exchangers, and pasteurization units, and increasing the facility's capacity with new reactors, heat exchangers, and pasteurization units.
“We've been pivotal in numerous biogas facility modernizations and expansions, accumulating the right knowledge to pinpoint the optimal upgrading approach”
