The Challange
The client, a bespoke modular anaerobic digestion (AD) developer, required a solution to utilise waste effluent generated from distillery processes at an independent distillery located in a remote island environment. The proposed AD system converts distillery waste effluent into usable heat energy, which is circulated back into the distillery to support production operations. Treating the waste effluent on-site removes the need to transport waste by road tanker to port for off-island disposal, significantly reducing logistical complexity and environmental impact.
The modular AD system was specifically suited to remote and island locations, enabling the conversion of unwanted liquid residues into on-site bio-energy while reducing carbon emissions through decreased transport and replacement of fossil fuel energy. Bio-energy generation was designed to align directly with production requirements at the distillery, ensuring efficient and sustainable energy use.
Clean water discharged from the AD plant was directed to a nearby bespoke Ecological Treatment System (ETS), creating a new wetland habitat and delivering biodiversity enhancement. The ETS was located within an environmentally sensitive area surrounded by multiple statutory designations, including Sites of Special Scientific Interest (SSSIs) and proximity to a Ramsar-designated site. Regulatory stakeholders raised concerns regarding potential impacts on protected species, particularly white-fronted geese and corncrakes.
Given the sensitivity of the location, the project required careful planning, detailed environmental assessment, and an innovative design approach. Through robust technical analysis and evidence-based justification, it was demonstrated that the proposed development would result in negligible environmental impact, satisfying both environmental regulators and the local planning authority and enabling progression of the project.
The Solution
Petro Safe undertook direct engagement with statutory consultees and the local planning authority, working closely with the wider project team to identify a practical solution that would enable the development to proceed. This collaborative approach focused on developing appropriate draft planning conditions that balanced regulatory requirements with project delivery objectives.
The local planning authority agreed to share draft planning condition wording, which was refined through continued consultation with statutory consultees to ensure a workable and proportionate solution. More detailed engagement was also carried out with environmental regulators to address recommended planning conditions and clarify the level of control required over the development, enabling concerns to be resolved and the project to move forward.
