3-Hydroxypropionate (3HP) is an important compound in the chemical industry, and the polymerized 3HP can be used as a bioplastic. In this review, we focus on polyesters consisting of 3HP monomers, including the homopolyester poly(3-hydroxypropionate) and copolyesters poly(3-hydroxybutyrate-co-3-hydroxypropionate), poly(3-hydroxypropionate-co-3-hydroxybutyrate-co-3-hydroxyhexanoate-co-3-hydroxyo...

Around the world, plastic materials are being produced and consumed more as global demand for increases. Consequently, both marine terrestrial life have been negatively affected by waste pollution. Multiple health risks associated with microplastics. The decomposition of plastics takes a long time, therefore reusing plastics, burning them, chemically treating burying them in landfills not best ...

Bioplastics are increasingly replacing traditional plastics in many sectors, but the legislative and operative frameworks for their disposal remain unclear: they should be collected treated together with organic fraction of municipal solid waste (OFMSW), often do not biodegrade satisfactorily plants that treat OFMSW. This work focuses on a type cellulose diacetate employed eyewear industry to a...

Research on biodegradable biopolymers has been increasing rapidly during the past few decades due to the environmental concerns related to plastic pollution. Polyhydroxyalkanoates (PHAs), the structurally versatile, biodegradable polyoxoesters produced by diverse group of microorganisms as intracellular storage granules have material properties similar to thermoplastics and identified as a prom...

This article presents experimental data of organosolv lignin from Poacea grass and structural changes after compounding and injection molding as presented in the research article "Effects of high-lignin-loading on thermal, mechanical, and morphological properties of bioplastic composites" [1]. It supplements the article with morphological (SEM), spectroscopic (31P NMR, FT-IR) and chromatographi...
