Anaerobic Digestion
We support anaerobic energy projects through the delivery of practical civil engineering solutions for anaerobic digestion and biogas facilities.
We work with clients to deliver infrastructure that enables the controlled processing of organic and agricultural waste to produce renewable gas and energy, supporting both sustainable waste management and low-carbon energy generation.
Our experience includes supporting the construction of anaerobic digestion facilities for a range of feedstocks, including agricultural, food and liquid waste streams. This requires careful coordination within regulated, operational environments where environmental controls, safety and programme certainty are critical.
By combining experienced teams with a practical delivery approach, we help clients develop and upgrade anaerobic energy assets that are safe, efficient and built for long-term operation.

FAQs
We believe strong working relationships begin with clear, open communication. Here, we answer some of the questions clients commonly ask about our delivery approach, commercial processes and experience.
Can Alpha assist with technical buildability during the design phase?
Yes. Through Early Contractor Involvement, our delivery teams review developing designs from a construction perspective, identifying potential issues such as utility clashes, ground conditions and access constraints before work begins. This practical input helps the wider project team develop solutions that are buildable, proportionate and aligned with programme and commercial requirements.
How does Alpha demonstrate its compliance standards in practice?
Compliance is embedded in the way we plan, manage and review our work, rather than being treated solely as a certification requirement. Alongside our ISO 9001, ISO 14001 and ISO 45001 accreditations, our approach includes daily site inspections by Site Managers, monthly formal safety tours by Contracts Managers and our Operations Director, and independent safety audits every two weeks.
Together, these checks provide ongoing oversight of our Integrated Management System, help verify that required hold points are followed and give clients a clear audit trail throughout delivery.
How do you manage construction works within live or high-risk environments?
We have extensive experience working in complex environments where maintaining business continuity is a key consideration. Whether operating within a manufacturing facility or critical utility site, our approach begins with project-specific planning through our Integrated Management System.
We develop appropriate SHEQ and environmental plans to identify and manage foreseeable operational risks, including noise, dust, access, logistics and segregation. Through regular liaison with clients and stakeholders, we coordinate our activities to help works progress safely and methodically while minimising the effect on existing operations and infrastructure.
What are the benefits of Alpha’s self delivery model?
Unlike management-only contractors, we operate with a directly employed workforce. This gives us greater visibility and control over safety, quality, behaviour and programme across the core works we self-deliver, including groundworks, drainage and concrete construction.
Reducing our reliance on external supply chains for critical activities can also provide greater continuity, quicker responses to changing site conditions and clearer accountability throughout delivery. This supports the consistent, right-first-time culture we aim to maintain across our projects.
