In 2022, the global production capacities of bioplastics amounted to 2.2 million tonnes. This translates to approximately 0.8 million hectares of land. Consequently, the surface required to grow sufficient feedstock for today’s bioplastics production just reaches a little bit more than 0.01 percent of the global agricultural area (5 billion hectares). Metaphorically speaking, this ratio correlates to the size of an average cherry tomato next to the Eiffel Tower.
Assuming continued strong growth of the bioplastics market based on the current stage of technological development, a market of 6.3 million tonnes could be achieved by the year 2027. This accounts for about 2.9 million hectares, or less than 0.06 percent of the global agricultural area. This estimation does not include the expected increased share of food residues, non-food crops or cellulosic biomass, which will lead to a smaller land use demand for bioplastics than the predicted amount mentioned above.

Sustainable sourcing of feedstock is key
The sustainable sourcing of feedstock is a prerequisite for more sustainable products. Negative impacts like deforestation of protected areas and environmental damage caused by bad agricultural practice must be avoided. The same applies to social criteria and human rights. The implementation of good agricultural practice, including guidelines for social standards (health protection etc.), is part of the sourcing strategy of many companies, e.g., by implementing a suppliers’ code of conduct.
Certification is an appropriate tool to ensure the sustainable sourcing of biomass
There are several stakeholder initiatives committed to achieving sustainability goals for specific products, such as the Better Sugar Cane Initiative. The independent certification of sustainability criteria is another approach to help follow the guidelines set by the European Renewable Energy Directive (RED). Corresponding certification schemes have been established in several European countries (e.g. ISCC).
