All‑Natural‑Domain Degradable Polyester

PDA: All‑Natural‑Domain Degradable Polyester The 3rd‑Generation Biopolymer Solving Marine Degradation Bottleneck Most conventional biodegradable polymers such as PLA and PBAT only degrade properly under industrial‑composting conditions. Once released into soil, fresh water or ocean, their degradation slows sharply, leaving persistent fragments and potential micro‑plastic risks. PDA — Polyesters Bio‑Degradable in All Natural Environments — is a 3rd‑generation degradable polyester developed by the technical team from Institute of Physics and Chemistry, Chinese Academy of Sciences. It addresses the long‑standing challenge: poor degradation performance of existing bioplastics in marine and open‑natural environments. Key Advantages of PDA🌱 True all‑natural‑domain biodegradation Fully mineralized in compost, soil, fresh water and seawater. End‑products are CO₂ and H₂O, zero micro‑plastic residues. Tunable degradation timeline Degradation cycle customizable from dozens of days to several years. Balances service‑life performance and end‑of‑life environmental safety. Good processability & mechanical performance Multiple grades available: high‑transparency, heat‑resistant, high‑strength, high‑barrier. Compatible with injection molding, film blowing, spinning and standard plastic manufacturing, minimal line modification required. Diversified feedstock & circular capability Works with fossil‑based or bio‑based monomers; supports chemical recycling for material circularity. Typical Applications Marine: aquaculture nets, protective meshes, seabed restoration parts, no manual recycling needed after service life Agriculture: degradable mulch film, agricultural ropes & nets Packaging & consumer goods: food‑contact packaging, single‑use articles, 3C protective packaging Others: 3D‑printing filaments, textile yarns, etc. Fighting plastic pollution is more than “compostable‑only”. Materials should fit real‑world natural surroundings. PDA enables products to return gently back to earth and ocean after use.
