In recent years, there has been increasing interest in developing novel materials based on natural biopolymers as a renewable alternative to petroleum-based plastics. The availability of proteins derived from agricultural by-products, along with their favourable properties, has fostered a renewed interest in protein-based materials, promoting research in innovative technologies. In this study, we propose the use of rapeseed protein-rich meal as the main ingredient for the preparation of novel sustainable materials combining excellent environmental properties such as biodegradability and renewability.

Article Synopsis
  • Community-based participatory research (CBPR) is a popular framework that enhances health outcomes in vulnerable populations by fostering greater community involvement in health programs.
  • A study analyzing 51 randomized controlled trials found that existing community interventions and institutional funding significantly increased engagement levels, while income status did not correlate with engagement.
  • The research highlights the importance of forming new partnerships and collaborative efforts in public health to effectively address social determinants of health among disadvantaged communities.

Article Synopsis
  • - Enzymatic digestion offers a gentler method for recycling plastic waste, but enzymes struggle to penetrate dense plastic materials, necessitating a pretreatment process.
  • - This study focuses on using hydrothermal liquefaction as a thermal pretreatment for rigid polyurethane foam prior to enzymatic digestion, analyzing the material's structure and composition through advanced techniques.
  • - Results indicate that combining hydrothermal liquefaction with enzymatic digestion effectively breaks down polyurethane, enabling the recovery of valuable chemicals and presenting a viable recycling solution.

In this study, we investigate the hydrothermal liquefaction (HTL) of PET separated from a densified postconsumer plastic mix, with the aim of recovering its monomer. This second raw material is made up of 90% polyolefin, while the remaining 10% is made up of PET, traces of metals, paper, and glass. After preliminary separation by density in water, two batch experiments were performed on the sunken fraction (composed mainly of PET) in a stainless steel autoclave at 345 °C for 30 and 20 min.

The influence of a nanodispersion of TiO in water (nanoparticle size: 40 nm, polydispersity index: 0.25), brushed on a Paraloid film and subjected to UV-Vis irradiation was evaluated. The TiO nanodispersions showed a tendency to reduce the molecular weight of Paraloid due to its photocatalytic properties.
