Beyond Buckthorns - The two barrel biogas digester - welcome the "Warp Core"

For some month, even years, I claimed that my initial biogas system “Jean Luc” was too big for a family of two. A 1000 litre IBC digester with an Hydrolic Retention Time (HRT) of 20 days can be fed about 50 litres / day. The most we fed over the years is 10 litres / day. If we calculate the size of the digester based on the amount of food scraps and the HRT the resulting size is 200 litres.
