Leaf protein concentrate from paunch grass and green waste: A technoeconomic analysis and lifecycle assessment
The global supply of food and feed protein needs to double during the first half of the 21st century. At present, food and feed protein is produced by livestock and arable crop farming. Further expansion of this protein production model is unsustainable in many countries due to overallocated water …
