Judge Dredd - Sector 190
Nothing goes to waste in Mega-City One, not even the dead. Corpses are sent to the nearest Resyk centre where the body is broken down into it components and rendered into other materials. Funeral services are held at Resyk so the bereaved can say goodbye to their loved ones and purchase reasonably priced souvenirs at the gift shop.
Bodies are fed onto a giant conveyor belt where machinery dissects each body and sends the parts onto the next relevant section.
Rich citizens can afford to pay for a burial at exclusive cemetaries.
