This project entailed the construction of large-capacity slipform concrete digestate holding tanks designed to support renewable energy operations. Located in Vegreville, Alberta, each tank was engineered to hold approximately 7 million litres of digestate—a byproduct of biowaste processing used in methane production. The facility was built to integrate seamlessly with advanced biowaste input and methane capture systems, contributing to sustainable energy generation.

The primary goals were to create durable, large-scale storage tanks capable of safely containing digestate while supporting efficient methane gas integration for energy recovery. Ensuring structural integrity, environmental safety, and operational compatibility with biowaste processing systems were critical objectives to maximize renewable energy output and minimize ecological impact.

The project utilized slipform concrete technology, which enabled continuous and uniform construction of the large cylindrical tanks, ensuring optimal strength and durability. Innovative methane integration systems were incorporated into the design to capture biogas emissions from the digestate, allowing for energy recovery and reducing greenhouse gas emissions. Additionally, specialized biowaste input processing systems were implemented to optimize feedstock management and facilitate continuous anaerobic digestion processes.

The completed digestate tanks demonstrated robust performance, effectively supporting the renewable energy plant’s operational requirements. Methane integration systems functioned as intended, enabling enhanced biogas capture and contributing to the facility’s sustainability goals. The tanks met stringent safety and environmental regulations, ensuring secure containment of digestate and reducing potential risks associated with biowaste storage.
