Timoleague Agri Gen is located in West Cork outside the village of Timoleague. We take waste food from food processing and manure from across Co. Cork and convert it into biogas and electricity through a process called anaerobic digestion. The site produces 500KW of renewable electricity. The site can accommodate a maximum of 48,500 tonnes per annum.
The residual by-product after the anaerobic digestion process is known as digestate. The digestate is rich in Nitrogen (N), Phosphate (P) and Potassium (K) and this biofertilizer can be land spread as a substitute for chemical fertilizer.
At Timoleague Agrigen we aim to close the loop on the circular economy. Anaerobic digestion makes the best use of organic materials by producing renewable energy. The residual by-product digestate acts as a nutrient rich fertilizer closing the nutrient cycle and reducing the amount of chemical fertilizer required.
1 – Waste intake
Waste material & manure feedstock is transported to the site via lorries. The feedstock is then dispensed within a reception building into a reception tank.
2 – Homogenization in the mix tank
Material from the reception tank is pump via sealed pipework to the mix tank where a homogenized feed is generated.
3 – Primary Digester
The mix tank feeds the primary digester at regular intervals. The primary digester is constantly heat and stirred to increase bacterial activity
4 – Secondary Digester
The secondary digester is a continuation of the process in the primary digester. It is heated to 50°C. This is a secondary process to breakdown long chain molecules which can be difficult to digest.
5 – Pasteurization
All feedstock material is pasteurized at the end of the process. The feedstock is heated to 70°C for 1 hour to kill any bacteria or pathogens present.
6 – Digestate storage
After pasteurisation the by-product known as digestate which is a nutrient rich fertilizer is stored in covered geomembrane lined storage lagoons. The digestate is then land spread as a substitute for chemical fertilizer.
