Como você pode ver abaixo, eles colocam seus pratos sujos e xícaras no replicador, que então inverte o processo de replicação (para permitir que o material seja usado mais tarde);
De DS9: Tempo Difícil
KEIKO : Make sure to put your plate in the replicator.
MOLLY : Okay.
Molly picks up her plate and puts it in the replicator. It disappears...
e DS9: A subida
SISKO : I'm afraid Jake's going through a phase of his own.
(a beat)
I don't know what's so difficult about putting a dirty plate back in the replicator.
Há também uma observação no Manual Técnico de Star Trek TNG de que alguns materiais replicados (água e vestuário) são recuperados através de meios mecânicos e químicos, enquanto os alimentos são mais frequentemente devolvidos à pilha de matérias-primas devido a limites de reabastecimento no espaço:
Material that cannot be directly recycled by mechanical or chemical
means is stored for matter synthesis recycling. This is accomplished
by molecular matrix replicators that actually dematerialize the waste
materials and rematerialize them in the form of desired objects or
materials stored in computer memory. While this process provides an
enormous variety of useful items, it is very energy intensive and many
everyday consumables (such as water and clothing) are recycled by less
energy intensive mechanical or chemical means. Certain types of
consumables (such as foodstuffs) are routinely recycled using matter
replication because this results in a considerable savings of stored
raw material
