Biorefineries are facilities that turn plants into useful products like biofuels and biomaterials. They can use different types of plants, like corn or wood, to make these products. Some biorefineries focus on using newer types of plants, like algae. To make biorefineries more efficient, researchers are combining different plant types and technologies. They are also developing tools to help design better biorefineries. By using a mix of plants and technologies, biorefineries can make a variety of products in a more sustainable way.
