This paper investigated the upcycling process of thermoplastic waste polystyrene (WPS) into thermosetting particleboard adhesive using two cross-linkers, namely methylene diphenyl diisocyanate (MDI) and maleic anhydride (MA). The WPS was dissolved in an organic co-solvent. The weight ratio of WPS/co-solvent was 1:9, and 10% of cross-linkers based on the WPS solids content were added subsequently at 60 °C under continuous stirring for 30 min. The adhesive properties, cohesion strength, and thermo-mechanical properties of WPS-based adhesives were examined to investigate the change of thermoplastic WPS to thermosetting adhesives. The bonding strength of WPS-based adhesives was evaluated in particleboard made of sengon (Falcataria moluccana (Miq.) Barneby & J.W. Grimes) wood and rice straw particles at different weight ratios according to the Japanese Industrial Standard (JIS) A 5908:2003. Rheology and Dynamic Mechanical Analysis revealed that modification with MDI and MA resulted in thermosetting properties in WPS-based adhesives by increasing the viscosity at a temperature above 72.7 °C and reaching the maximum storage modulus above 90.8 °C. WPS modified with MDI had a lower activation energy (Ea) value (83.4 kJ/mole) compared to the WPS modified with MA (150.8 kJ/mole), indicating the cross-linking with MDI was much faster compared with MA. Particleboard fabricated from 100% sengon wood particles bonded with WPS modified with MDI fulfilled the minimum requirement of JIS A 5908:2003 for interior applications.

This research produced textile pigment printing paste using expanded polystyrene (EPS) as a binder, sodium alginate as a thickener, and ultramarine pigment. The printing paste production was optimized through response surface methodology, using central composite design (CCD). The dynamic viscosity of the produced printing paste samples ranges from 5200 to 5550.50 cP (Centi Poise). The Fourier infrared transform (FTIR) spectroscopy revealed the functional groups present in the printing paste. The result of the thermogravimetric analysis (TGA) conducted shows a first step decomposition of 94.14% that occurred at the range of 30.96°C–127.75°C. Differential scanning calorimetry (DSC) showed an endothermic transition at 119.44°C due to the absorption of energy during the breaking of printing paste bonds. Textile characterization such as wash fastness, croak fastness, and light fastness was carried out to determine the suitability of the print paste on cotton and polyester fabrics. The results of the fastness tests range from 4 to 5 for wash fastness, 3 to 4/5 for croak fastness, and 4 to 6 for light fastness. The optimum values of the model variables are thickener (50%), binder (40%), and pigment (5%). The performance of the printing paste as revealed from the results is moderate and comparable with textile printing paste suitable for commercial application.

“…The development of new products from recycled EPS has been reported in the literature substantially; e.g., in the production of ceramic coating foams [46], in construction [47][48][49][50][51][52], in natural fiber/polymer composites [53], in composite [54], as a gemstone for application in contemporary jewelry using silver recovered from scrap sources [55], in resin for wood [56], modified castor oil [57], in the form of beads on the ground [58], adhesives for paper and wood [59], in nanofibers with chitosan as an adsorbent in the removal of lead (II) from water [60], in a fibrous mat for air filter media [61], as thermal insulation material [62]. However, the development of an optimal adhesive for the footwear industry from recycled EPS from the packaging industry is unknown by assessing the qualitative quality perceived by the experts on the production line.…”

Development of an Adhesive Based on Waste Management as a Mechanism Towards Sustainability

Plastic pollution is an alarming issue; it is a phenomenon that, in addition to altering health, is capable of generating damage to the environment. It is estimated that only 8% of plastics are recycled and that 76% end up in landfill sites or are indiscriminately disposed of into the environment. “Single-use” plastics contribute the most to the generation of pollution due their short “life cycle” since after their useful life, they are discarded. Expanded Polystyrene (EPS), one of the plastics with the greatest use as a packaging material, has a complicated recycling process due to its volume and weight characteristics. Based on the above, following the Circular Economy model, the optimal development of an adhesive for the cut-sole union is addressed through the analysis by classified attributes using an orthogonal array L9(3)4 of Taguchi. Of the factors under study, it was determined that the “adhesive formulation” is the factor that statistically significantly influences the degree of adhesion of the cut-sole, followed by the “type of sole”. The adhesive with post-consumer EPS is viable and contributes to minimizing the environmental pollution footprint as a strategy toward sustainability.
