Gather foods with calories, the higher calorie filled a food is, the more propane and fertilizer is produced. Gather these foods my looting, fishing, trapping, foraging, or farming  
(I personally recommend fishing because you don't need to do much work other than the setup)

Fill the Home Biogas Unit with these foods and then plunge the funnel

After some time, the Home Biogas Unit will pump out units of propane and fertilizer. You can gather propane with a propane tank and the fertilizer with a bucket, which needs to be mixed with dirt to be usable

The hotter it is outside, the more efficient the Home Biogas Unit it is, and in the winter time, it's barely usable, so I advise only using it in the late Spring and Summer times for best production
