The power of the people: energy recovery through anaerobic digestion
Wastewater and organic-material treatment can create opportunities to recover useful energy.
Informational rewrite based on the topic and available supporting material from David Brushett’s original LinkedIn post. The date shown is the original post date; wording was reviewed in September 2026.
Anaerobic digestion uses microorganisms to break down organic material without oxygen, producing biogas. Depending on the facility and gas treatment, that gas can provide useful energy alongside the treatment service.
Consider treatment and energy together
The energy opportunity depends on the material entering the process, gas yield, the facility’s own energy requirements and a practical use for the recovered energy. Heat recovery is particularly useful when there is a suitable nearby thermal demand.

For owners considering similar opportunities, the central lesson is to evaluate treatment performance, maintenance and energy recovery together. This is an informational technology article rather than a PB Energy project account.
