Summary: Electrothermal processes were investigated in pyroresistive composites of high-density polyethylene with carbon black and carbon fibers. The kinetic heating curves showed an exponential dependence with a heating rate constant for each composite. Equilibrium temperature was reached after a short heating time, and decreased with the presence of positive temperature coefficient of resistance (PTC) effect. The composites exhibited self-regulating capability and the equilibrium temperature depended on the applied voltage and electric power with different relationships. An application of using HDPE-CB composite as a heating element for resistance welding was demonstrated.

Summary: In recent years, the valorization of food waste as an energy and/or chemicals source has gained great attention. Coffee by-products, such as coffee pulp, coffee husks, silver skin, and spent coffee, have been investigated for their potential as antioxidants and valuable chemicals, as well as fillers in composites. This study explores a new valorization route for coffee silver skin (CSS), which is typically dumped, by incorporating it into biocomposites based on poly(butylene succinate-co-adipate) (PBSA). The resulting mulching films, formulated with up to 30 wt% CSS, exhibit hydrophilic properties and release plant growth-promoting bacteria, as confirmed by in-vitro tests and pot experiments using lettuce as a model crop. This approach offers potential advantages in terms of soil preservation and fertilization, reduction of polymeric materials in mulching products, and the utilization of waste.

Summary: This study investigates the effects of fibre concentration on the mechanical response of welded glass-fibre-reinforced polypropylene (GF-PP). Experimental observations reveal a significant reduction in weld ratio, up to 60%, indicating a decreased strength compared to the bulk material. Increasing fibre content in the welded material results in a decrease in stress at break and strain at the maximum stress. The use of DIC technique and X-ray microtomography further confirms the localized strain amplification in the welded zone due to the significant increase in fibre density.
