Objective: To analyze the recent contributions of bioplastics in addressing environmental problems caused by plastic pollution. Design/Methodology/Approach: A literature review was carried out on definitions plastics and bioplastics, sources raw materials, processing technologies methods to assess biodegradation. Current practices for final disposal and/or reuse were also examined. Special emph...

   This procedure has developed the use of TiO2 nanoparticles as an environmentally friendly and highly efficient heterogenous nanocatalyst for the eco-safe, facile and one-pot three-component Biginelli synthesis of biologically active corresponding 3,4-dihydropyrimidin-2-(1H)-one/thione derivatives under solvent-free conditions. This eco-friendly protocol provi...
