Manuel Marques is of the opinion that all cork companies should be members of APCOR. "I recognize the important role of APCOR in representing the cork sector nationally and internationally as well as help in other areas such fiscal or labor issues" he states. And continues: "mainly at the international level the role of APCOR in communication and marketing, informing our customers of the characteristics and advantages of cork has been of fundamental importance"
