Abstract
In this work, the suitability of colour monitoring during composting is reported. Two composting experiments were conducted with winery wastes for five months in the laboratory. In the first experiment the composting of spent grape marc was studied, whereas in the second a mixture of hydrolyzed grape marc (residue of the treatment for biotechnological production of additives), wine lees and CaCO3 was composted. In addition to monitoring common chemical parameters, the colour of the materials was determined, both in the Munsell system and in the CIELAB space. During the five months of composting, the winery wastes showed a very low degree of evolution in their chemical properties, restricted to the first three months. The colour parameters were modified with composting time, particularly in the first months, indicating their relationship with the evolution of the materials in composting.
