A tombstone is provided having a stone appearance. The tombstone includes a tombstone base and a tombstone head made of recycled plastic. The tombstone is made of high impact plastic diverted from a waste stream and injection molded under pressure of at least about 1 MPa. The lightweight plastic tombstone is secured by digging a hole; pouring uncured cement into the hole; inserting a spike through the tombstone into the uncured cement; and allowing the uncured cement to cure.
