We present a design for programmable luminescent tags fully made from biodegradable, ready-to-use materials (bioPLTs) allowing for waste-free information storage. Quinine embedded in polylactic acid as host material provides sufficient room temperature phosphorescence (RTP) for easy readout even under continuous-wave illumination. Exceval is used as oxygen blocking layer to locally control the oxygen-sensitive RTP emission for high-resolution writing of information. Accordingly, these bioPLTs exhibit all function-defining characteristics also found in their regular non-biodegradable analogs even including a flexible design when using polylactic acid foils as substrate.
