Indian Space Research Organisation (@isro) chairperson K Sivan in November 2021, mentioned that they are working on futuristic technologies such as self-eating rockets and vanishing satellites as part of the measure to reduce space debris.

“All our rockets have metal casings that are dropped into the sea after launch or become (final stage) space debris. We are working on a technology where rockets will effectively ‘eat themselves’ leaving no waste.” Sivan elaborated.
