Malden is a Pay-As-You-Throw (PAYT) community where residents pay for the trash they dispose. It affects persons living in households up to six units. It allows each household to control its volume of trash disposal and encourages recycling. All residents must use official light blue City of Malden trash bags. Under the PAYT program, recyclables and yard waste are collected at no additional cost. (Recyclables are picked up weekly and yard waste collection is on a seasonal schedule).The department also holds hazardous waste recycling days throughout the year.
