United Nations recommends bioplastics as a sustainable alternative to conventional plastics
Mulch films are of crucial importance as they represent the second largest share of plastic films used in agriculture. "Mulch films made from biodegradable plastics provide significant benefits where retrieval, recycling, and reuse pose significant problems. These are specifically designed to biodegrade effectively and can therefore be incorporated into the soil post-harvest," explained François de Bie. In contrast, especially thin non-biodegradable mulching films display a poor selection, management, and retrieval, which can lead to a significant level of pollution on the fields. Even where conventional mulch films are removed from the field, they are often heavily contaminated with soils and plant residues, which inhibits the recycling process.
The FAO report also emphasises the need to develop polymers that are biodegradable in the marine environment. "Although any kind of littering, should be avoided, a certain level of unintentional loss of fishing gear will always take place. Therefore, it is important to foster the adoption of biodegradable solutions", stated the Chairman of EUBP. In the case of used products contaminated with fish residues, e.g., fish boxes usually made from conventional plastics, biopolymers, according to FAO, may ease the recycling process.
The importance of an improved data situation regarding the life cycle assessment of bio-based agricultural plastic as well as the behaviour and rate of degradation of biodegradable products is also underlined in the report. "We strongly support all efforts that contribute to a further improvement of the current data situation. However, this can't be done by the bioplastics industry alone. In order to establish a proper data pool, we need stronger political support. For the European market, the European Commission should take over a leadership role to facilitate and coordinate data pooling," stated Hasso von Pogrell , Managing Director of EUBP. The report also highlights the role of research and innovation grants as means of pump-priming new ideas which lead to the development of new products. "However, the funding of research alone is not enough. An appropriate policy framework for bio-based, biodegradable and compostable plastics is also needed, to capture the sustainable benefits of these products in Europe ," concluded von Pogrell.
