Bioplastics can be chemically recycled into nitrogen-rich fertilizers in a facile and environmentally friendly way

"The team focused on poly (isosorbide carbonate), or "PIC," a type of bio-based polycarbonate that has garnered much attention as an alternative to petroleum-based polycarbonates. PIC is produced using a non-toxic material derived from glucose called isosorbide (ISB) as a monomer. The interesting part is that the carbonate links that join the ISB units can be severed using ammonia (NH3) in a process known as ‘ammonolysis’. The process produces urea, a nitrogen-rich molecule that is widely used as a fertilizer"
