PLA Origin

Raw material and lifecycle

Polylactide (PLA) is prepared by polymerizing lactic acid obtained from starch or sugar-containing starting materials. The process is now considerably more cost-effective and requires less energy than years ago and makes it very attractive for the industry.

Sugar cane is a perennial plant that forms grass with up to seven meters high and five centimeters thick stems with sugar-storing marrow (7 to 20 percent sucrose).

In our case we use sugar cane and bitter cassava from Thailand, since the natural location for the cultivation is ideal there.

Did you know?

The production of 1 tonne of PLA from sugar cane with an area requirement of 0.16 hectares is much more efficient than the production of 1 tonne PLA from corn (0.37 hectares).

Lifecycle of PLA

The lifecycle of PLA is based on a sustainable closed circulation system. The advantage of PLA is that it does not have a negative impact on the environment and can make a valuable contribution for the industry, consumers and the environment at the same time.

PLA products are reusable and recyclable and can be transformed into a new product life cycle at the end of their lifespan. Thus, PLA provides the industry with a very high-quality material stream and is able to use raw materials more efficiently and reduce material waste.

PLA circuit includes the following possible stations:

  • Reuse
  • Recycling
  • Waste incineration and thus, energy production (even carbon dioxide neutral due to your biobased content)
  • Compostable and biodegradable as soon as it interacts directly with the environment
  • Recovery of raw materials

Example:

  • PLA can be downstreamed to various products like blow film bag, cups, packaging films, injection molding packaging solutions, thermoforming sheets etc.

We use the PLA waste material, for instance, from our non-woven production for the paper industry and try to optimize the loop system even in our production.
