Various agricultural waste materials, such as cassava stems, pineapple leaves, banana peels, and corn pulp, were developed into natural biodegradable packaging, adding value to the waste. Hence, this research aimed develop biocomposites inspect their mechanical physical properties. Fresh galangal root was washed dried at 80°C for 12 hours then ground achieve a particle size of 250 microns (GR250) 400 (GR400). Then, they mixed with PBS ratio PBS: GR250 80:20 wt.%. Later, mixtures passed through extruder, plastic strands obtained. these shredded small pellets called biocomposite pellets. These formed by heat 150°C 5 minutes under pressure 10 MPa obtain specimens. assessed properties (tensile strength, impact flexural strength). Also, (water absorption, density, morphology, percentage degradation) performed. The results could imply that GR400 PBS-based cause reductions in structural integrity elasticity. PBS/GR would assert less force. reflect PBS/GR250 PBS/GR400 had more ability resist bending stresses than neat PBS. tended degrade faster, supported microstructure observation lower density compared PBS/GR250. It be concluded added developing based-biocomposite. Galangal can produce food containers stresses. Biocomposite have property environmentally friendly aspects.

The application of mulch films for preserving soil moisture and preventing weed growth has been a part agricultural practice decades. Different materials have used as films, but polyethylene plastic considered most effective due to its excellent mechanical strength, low cost ability act barrier sunlight water. However, use carries risk pollution health hazards, hence new laws passed replace it completely with other over the next few years. Research find out about biodegradable polymers this purpose gained impetus in past years, driven by regulations United Nations Organization’s Sustainable Development Goals. primary requisite these is biodegradability under natural climatic conditions without production any toxic residual compounds. Therefore, developed from fossil fuels, microorganisms, animals plants are viable options using mulching material. solution not simple since each polymer different properties compromise be made terms film.

Petro-plastic wastes cause serious environmental contamination that require effective solutions. Developing alternatives to petro-plastics and exploring feasible degrading methods are two solving routes. Bio-plastics like polyhydroxyalkanoates (PHAs), polylactic acid (PLA), polycaprolactone (PCL), poly (butylene succinate) (PBS), (ethylene furanoate) s (PEFs) (PES) have emerged as promising alternatives. Meanwhile, biodegradation plays important roles in recycling plastics (e.g., bio-plastics PHAs, PLA, PCL, PBS, PEFs PES) terephthalate) (PET) plasticizers phthalate esters, PAEs). All these bio- petro-materials show structure similarity by connecting monomers through ester bond. Thus, this review focused on summarized the sequences structures of microbial enzymes catalyzing ester-bond synthesis. Most synthetic belonged α/β-hydrolases with conserved serine catalytic active site catalyzed polymerization forming For enzymatic plastic degradation, about PEFs, PES PET were discussed, most also α/β hydrolases a residue serine, nucleophilically attacked bond substrate generate cleavage backbone. Enzymes hydrolysis representative plasticizer PAEs divided into three types (I, II, III). Type I hydrolyzed only one PAEs, type II mono-ester phthalates, III di-ester bonds PAEs. Divergences mechanisms among still unclear. This provided references for producing bio-plastics, or from an point view.
