The image features three segments related to the processing of Turkish coffee grounds. The first part shows a close-up view of raw Turkish coffee grounds in a pile, indicating their granular texture. The second part displays a measuring beaker containing brewed coffee extract, marked with measurement increments on the side. Below these images, there is a diagram illustrating the process: starting with Turkish coffee grounds in a container, then showing an oven labeled with a duration of thirty-six hours at eighty degrees Celsius, followed by the final product of dried Turkish coffee grounds in a container. The overall layout emphasizes a step-by-step transformation of the coffee grounds through different states.(a) Biopolymer 4043D PLA matrix; (b) spent coffee grounds; (c) drying spent coffee grounds
