Here’s how U.S. native prairie grass can be turned into bioplastics

L’ampio utilizzo delle pellicole da pacciamatura nelle colture di fragole si traduce nella dispersione di micro e macro frammenti di plastica nel suolo. Un fenomeno, rivela uno studio californiano, i cui effetti possono manifestarsi per decenni
The Patrica plant in Lazio is an example of the potential of the circular bioeconomy: Novamont has transformed a historic Italian chemical hub into a highly renewable biopolyester production centre, obtained from materials of vegetable origin. PHOTO: NovamontNovamont

Circular bioeconomy, biobased industries need specific codes

Plastic, glass, metals: the “enemies” that dirty the compost

,
The alarm emerges from a series of video interviews with managers of composting plants carried out by the italian Biorepack consortium. Too high percentages of "foreign fractions" (up to 12%) make it more difficult and expensive to make compost. On the other hand, compostable, flexible and rigid bioplastics were promoted with flying colors: "very useful for increasing quantity and quality of the final product"
Contamination and plastic pollution in soils are even greater than those affecting the seas and oceans.

Pollution, there is more plastic in agricultural land than in the oceans

,
FAO produced the first report on the use of plastics in agri-food systems. Pollution is pervasive, especially in Asia. The solutions revolve around the "6Rs": reject, redesign, reduce, reuse, recycle and recover. It is essential to invest in the search for alternative products
