• Capacity building in research on industrial
biogas in Ghana
Sign a Memorandum of Understanding
(MoU) on academic collaboration between
KNUST and POSTECH
Support two PhD students to be trained at
KNUST on biogas 2

Technical assessments (2/4)
Options compared: •Option 1: very large plant, low biogas output
•Option 2: treats large quantity of waste than options 3 and 4 (larger CSTR plant) but due to lower solids content, biogas output is lower
•Option 3: same plant as option 4 but due to lower solids content, lower biogas output
Recommended solution: option 4 •Highest biogas output obtainable within the available budget
•Treating all of the solid fraction produced by separation; liquid fraction to be treated in a plant extension
•Removing most of the organic components from the waste water, reducing environmental load
