“The first generation biotechnologies utilize edible biomass such as sugarcane, corn, and cassava as their feedstock. However, using edible biomass can create competition for food by increasing food prices. Second generation biotechnologies now utilize inedible lignocellulosic biomass as feedstock, which is advantageous because it is carbon neutral and does not require the use of foods that are otherwise consumed by humans.” – Biochemical Engineering Journal, 2018
