A team from Robert Gordon University will present study results for the AD techno-economic-environment analysis of potential options for waste to energy (power & heat) as well as biofertilizers supply.
In brief, there is a scope for recycling of organic waste from agricultural, horticultural and food operations on Orkney Islands, and this project seeks to provide detailed assessment of the feasibility of using these wastes, together with possible crop supply as feedstock for anaerobic digestion (AD). Anaerobic digestion is the process by which organic matter such as animal or food waste is broken down by microorganisms to produce biogas and biofertiliser.
The aim of this project is to conduct a feasibility study on a community driven Anaerobic Digester (AD) Plant Installation in Orkney for the Orkney Islands to address organic waste management. The project aimed to determine:
- Quantify the volumes of feedstock that would be available and the available area of land to spread digestate to
- Determine whether there is stakeholder interest in running an AD plant and potential sites for an AD plant
- Quantify heat, power and biofertilizers that can be produced from organic waste volumes available in Orkney Islands
- Conduct both economic analysis and environmental impact for an AD in Orkney Islands
The project was funded by the Industrial Biotechnology Innovation Centre (IBioIC) and run by Strathendrick Biogas Ltd and Robert Gordon University (RGU). The project was developed from the Circular Economy workshop we held in Orkney in 2019 (in partnership with HIE and IBioIC) in collaboration with NFU, EMEC, SAC Consulting, Highlands and Islands Enterprise, and OIC locally.
