When recycling PLA, the plant-based feedstock is replaced by a collected PLA waste feedstock. Therefore, the amount of land use is proportionally decreased according to the amount of recycled content. Figure 6 shows that for a 20% and 30% recycled content rPLA, the land use impact reduces by 20% and 30%, respectively.
