Project Overview
A 5MW (effectively 3.5MW) anaerobic digestion site in the North of England, which due to a number of factors had been effectively ‘mothballed’, operating on only a handful of tanker per week and producing electrical outputs of less than 10% of targeted levels.
Description of solution or innovation
Upon investigation by Waste4Generation (W4G), the digesters were found to be highly contaminated with debris, rocks and indigestible feedstock. W4G’s services were engaged with the aim of getting the plant’s processes and biology back on track with a minimal budget in order to avoid a likely site closure.
Initial Investigation:
- Phase 1 – External de-grit
- Phase 2 – Commissioning
- Phase 3 – Ramp-up and operations procedures implemented
Steady & continued increases in production- the increase in electrical production steadily increased following the de-gritting and re seeding program, we were then able to effectively ramp production in both a stable and healthy manner.
