Topic Information

Dear Colleagues,

The way we transform material substances into many different forms has changed over the years and has continued to change since ancient times as a result of ideas, aspirations, ambitions, or simply by chance. At present, cutting-edge solutions are required to meet “Net Zero” targets and/or solutions based on “Industry 4.0” technologies. This topic is open to all. Let’s work together to define and redefine “sustainability” and “green” in chemical and biochemical processing. Subjects of interest include, but are certainly not limited to, the following:

  • Advanced manufacturing technologies
  • Advanced materials and nanomaterials 
  • Bioactive compounds 
  • Green solvents 
  • Smart sensors
  • Biofuels 
  • Residue reutilization 
  • Waste minimization 
  • Simulation and integration
  • Carbon footprint and eco-industry 
  • Life cycle assessment

Urban solid waste (USW) is a promising alternative source of valuable chemical compounds. It is considered an adsorbent material due to its chemical structure, porosity and electronic charge available to form chemical bonds and can be recovered or transformed for use in bioprocesses and industrial applications. This is the case with cigarette butts (CBs), which consist of thousands of substances that can be chemically converted for various purposes. This work showed high efficiency in the production of cellulose mass from the recycling of CBs, a patented technology in operation at the company Poiato Recicla—SP. The lignin-like solid (LLS)—a material obtained from the recycling of cigarette butts (CBs) by catalytic transfer hydrogenation (CTH), under non-rigorous conditions—showed high efficiency in its conversion into molecules of great interest. In the bio-oil obtained, characterized by analyses such as GCMS and RMN 2D HSQC, a mixture of predominantly hydrocarbons (many of them with cyclic and/or branched chains) was identified in almost all the experiments. This method demonstrates the potential of the TCH process for SSLs and completes the recycling chain designed for CBs, promoting their complete conversion into chemical compounds of greater interest.

The use of natural materials as adsorbents and the environmentally friendly removal of pollutants and azo dyes from water are important topics today. The goal of this research work was to assess the utility of Luffa cylindrica (L. cylindrica) as a natural and non-conventional adsorbent for azo dyes in water on a large scale (2 L). An azo dye (AD) at a concentration of 0.250 g/L was removed from the solution at a rate of 63.07% using 10.0 g/L doses of L. cylindrica, and the maximum adsorption capacity of L. cylindrica was 25.25 mg/g. L. cylindrica desorbed 95.8% of the AD in 0.1 M NaOH. Thermodynamically, the adsorption occurs through pseudo-second-order kinetics and the behaviors adjust better to the Langmuir isotherm. The analysis of variance (p-value < 0.05) shows that the contact time and the concentration of AD significantly influence the adsorption capacity and removal of AD. Few studies have examined the environmentally friendly removal of azo dyes from water using a natural non-conventional adsorbent. Full article

The enzymatic resolution of chiral sofosbuvir precursors is a critical step in producing stereoisomerically pure ProTide drugs, essential for their therapeutic efficacy. In this study, a mutated phosphotriesterase (W131M-PTE) was immobilized onto various polymeric macroporous beads, including commercial immobead 150P (IB), modified (IB-EDA and IB-MTD), and synthetic polyacrylamide (PAM) beads functionalized with glutaraldehyde (PAM-GA) or 1-Ethyl-3-(3-dimethyl aminopropyl) carbodiimide (PAM-EDC). The immobilization efficiency, stability, and reusability of the enzyme were systematically evaluated. Among the tested supports, PAM-EDC demonstrated superior performance, retaining high enzymatic activity across multiple cycles and achieving a 92% yield of the (Sp)-diastereomer. The study highlights the potential of immobilized W131M-PTE as a cost-effective and scalable solution for chiral separation in pharmaceutical manufacturing, with implications for broader applications in ProTide drug production.
