Renewable/degradable plastics

The degradable bio-films used today consist mainly of natural fibres, sugar and starch of plant origin and are therefore not without controversy. The fact that this type of packaging may not normally be put into composting also goes against the widespread use of these bioplastics. On the other hand, we see a sensible use of the films in the horticultural sector, with the aim of composting the packaging together with the plant/roots after use.

Newer developments, the non-degradable but renewable bio-polymers such as bio-PP or bio-PE, nevertheless conserve fossil-based resources and reduce the CO2 footprint.
