Halston prepared an environmental impact assessment report (EIAR) and Appropriate Assessment reports to support planning applications for a centralised 90k tonne per annum feedstock capacity biogas plant with a 5MWe output. Halston were also responsible for preparation of licensing applications from the Environmental Protection Agency and the Department of Agriculture Food and Marine. The licensed facility is a fully bunded site and includes; a feedstock reception infrastructure and plant, digester vessels, pasteurisation plant, compresssion and bottling plant, gas purification plant, enclosed flare, control rooms, and associated drainage infrastructure.
The development is proposed on a 22-acre site and comprises a proposed biogas plant capable of producing 12MWe. The proposed biogas plant designed to accept up to 95,000 tonnes of non-hazardous biodegradable feedstock per annum. The plant includes the initial waste pre-treatment phase followed by anaerobic digestion. The design includes a continuously fed system with digestion carried out in a multi-stage mesophilic process. Biogas is recovered from the process and upgraded to biomethane and carbon dioxide. Digestate generated will be provided as an organic fertiliser and used for agricultural purposes. The need for the project is driven a wide range of EU policies which relevant to developments, including directives and communications on climate change, waste, renewable energy and agriculture /bioeconomy.
Halston was responsible for project managing all facets of the planning application, including; site suitability options appraisal, consultation with stakeholders, provision of engineering drawings, preparation of an Environmental Impact Assessment Report (EIAR), Natura Impact Statement (NIS) and other supporting documentation.
