The methods in which to reduce the P.L.A final price and making production processes
more eco-friendly, in comparison to earlier production process, include
1. Implementation of crop residue from corn or other plants
2. Use of unfermentable residues as a heat source, as well as substituting some
part of electricity energy by alternative sources, such as wind or solar power energy
One of the most positive effects of PLA production when compared with the
production of other hydrocarbon-based polymers is the decrease of CO2 emission.
“Net” or “residual” emissions are calculated as total emissions from the cradle
to the factory gate minus carbon dioxide uptake that occurs during corn production,
the amount is negative for present PLA production. Negative Net-Emission means
that the total CO2 consumption from the cradle to factory is more than its emission
to the environment, making their net CO2 emission is less than for other polymers.
