Digester facility revenue is often heavily tied to total biogas production. A good digester operator is always looking for ways to produce more biogas. One of the simplest ways of doing this is by evaluating feedstocks. While increased volume and potency of the feedstock is often the objective, one must be careful to understand to affect this may have on the system and its stakeholder’s operations. At the DCCD, CFP has made a number of feedstock modifications over the years to increase biogas yield, while also:

1. Prolonging the life and function of the digesters.
2. Accounting for mechanically damaging side effects.
3. Reducing overall volume burden put on participating farmers.
4. Taking into account overall nutrient loading on the surrounding landbase.
