100% Biodegradable Short Cut Fiber PLA Polylactic Acid Fiber For Paper-Making
PLA Degradable Fiber 1.5D For Medical Nonwoven
1 . Descriptions:
PLA production is a popular idea as it represents the fulfillment of the dream of cost-efficient, non-petroleum plastic production. The huge benefit of PLA as a bioplastic is its versatility and the fact that it naturally degrades when exposed to the environment. For example, a PLA bottle left in the ocean would typically degrade in six to 24 months. Compared to conventional plastics (which in the same environment can take several hundred to a thousand years to degrade) this is truly phenomenal

3 . Advantages:
- Greenhouse gas emissions of bio-based plastics amount to less than 3 KG of CO2 equivalents per KG of plastic, less than that of petrochemical based plastics which produce an average of 6 KG of CO2 equivalents per KG of plastic..
- the production of bio-based polymers, in comparison to all petrochemical plastics examined, leads to savings in fossil resources. The biggest savings potential can be found in comparison with polycarbonate (PC). The average savings potential in the production of PLA amounts to 56 ± 13 megajoules per kilogram of plastics here.
PLA can be recycled as it can be broken down to its original monomer by a thermal depolymerization process or by hydrolysis. The outcome is a monomer solution that can be purified and used for subsequent PLA production without any loss of quality.
However, the recycling infrastructure for PLA hasn’t been scaled up yet, mainly because end markets for the recycled material haven’t been developed.
While recycling PLA might be a viable solution in the future, we currently recommend composting as a preferred end-of-life option, especially as foodservice packaging is often contaminated with food scraps, making recycling impractical.
