The provided diagram illustrates how biogas is manufactured using natural ingredients.
Overall, this man-made operation consists of 5 main steps, starting with the collection of agricultural material, and culminating in the distribution of biogas.
First of all, waste from cattle like cows and pigs, as well as disused stalks are harvested, are gathered and shredded into pieces. Being transported by a specialized farming vehicle, the mixture is next sent to a feeder, then to a large dome through a pipe controlled by a macerator. Inside the container, the concoction is fermented at a high temperature, forming biogas.
Afterward, the end product is delivered to 3 different areas. The first one is a hybrid power plant, where biogas is used to create common energy such as heat and electricity. Meanwhile, the second role of biogas can be found in a biomethane-enhancing factory, in which biogas is turned into a type of gas that fuels automobiles and heat-based equipment. Finally, the environmentally friendly air’s third niche is to be utilized as a material for compost production. The fertilizer can be either used for decorative plants or large-scale farming.
