Biodegradability Evaluation of Polymers by ISO 148552

Eco-Friendliness Face-Off: - Recyclability vs. Biodegradability: PET can be recycled multiple times, reducing the need for new plastic production. PLA, on the other hand, biodegrades but requires industrial composting facilities.. The experiments confirmed the ability of the two bacteria and fungi strains in biodegradation of polylactide (PLA) and polyethylene terephthalate (PET). The combination of these microorganisms with some tested plant species increased the microbial population in the soil and, at the same time, degradation of the plastic films.

The difference between polylactic acid (PLA) and PET is essentially the difference between "biodegradable" and "fossil-based, non-degradable" materials. Each has its own advantages and disadvantages: PLA has advantages in resource sustainability and ultimate degradability, but has shortcomings in performance and cost; PET is more competitive in performance, processability, and cost, but lacks.. Ultimately, the choice between PET and PLA should be based on carefully evaluating the specific product requirements, sustainability goals, and available resources. As sustainable packaging solutions evolve, it's important to consider the broader environmental impact and seek innovative ways to reduce waste and promote a circular economy.
