Concerning  the  conservation,  of  the  protection  and  the  improvement  of  the 
quality  of  the  environment,  as  well  as  for  the  protection  of  the  health  of  the 
persons and the careful and rational use of natural resources, MX15 has to be the 
object  of  a  selective  collection  for  the  electronic  equipments  and  cannot  be 
scrapped  with  the  normal  domestic  waste.  The  user  thus  has  the  obligation  to 
separate  the  MX15  of  the  other  waste  so  as  to  guarantee  that  it  is  recycled  in  a
