Hi guys

Can I run some calculations by you see if they make sense to you!

If we assume that per 100g biomass we can get a biogas production of 6.63litres/day then for 20 tonnes biomass with a retention time of 60 days, the biogas production in m3 is

(6.63 * 10 * 1000 * 60 HRT)/1000 = 3978m3

Thanks
