The newest method for recycling waste linear low-density polyethylene (LLDPE) is the thermo-catalytic degradation technique known as catalytic pyrolysis. Typically, it is limited by 500–800 °C high temperatures. Catalytic pyrolysis releases toxins and forms harmful carbonized char. The current study is based on exposing wasted LLDPE to different gamma irradiation doses and then pyrolysis in castor oil (150–300 °C). The output product of Ir-(rLLDPE) is turned into another compound with a new structural architecture (sponge-like). SEM analysis confirms conversion, showing sponge-like spicules and layers. Ir-(rLLDPE) is sponge-like with a soft, malleable, absorbent texture. The DSC demonstrates altered thermal properties, with a melting point at 121 °C splitting into two peaks (endothermic at 117 °C and exothermic at 160 °C). The exothermic peaks signify the curing process of the sponge-like material. Ir-(rLLDPE) is assessed as an adsorbent for aqueous oils and solvents. The study examines irradiation doses, pyrolysis temperature, and time on adsorbent capacity. The oil removal obeys the Langmuir isotherm with monolayer adsorption, with a maximum adsorption capacity of 24.75 g/g of waste oil and 43 g/g of 1,1,2,2-tetrachloroethane. Squashing maintains adsorption after 20 reuses. Data shows sponges effectively clean marine oil spills and solvents.

“…In pursuit of sustainable alternatives, various studies have explored the production of SA through fermentation processes using renewable resources. In this approach, sugars derived from renewable feedstocks, such as agricultural waste (e.g., corn, wheat, and rice straw, oil palm trunk, and empty fruit bunch), food waste, fruit and vegetable waste, and aquatic biomass (e.g., microalgae, seaweed, and aquatic plants), are utilized by microorganisms like Anaerobiospirillum succiniciproducens, Mannheimia succiniciproducens, and Actinobacillus succinogenes (Li et al, 2010;Putri et al, 2023;Akhtar et al, 2017;Dessie et al, 2018;, Kuglarz et al, 2023;Patsalaou et al, 2020;Bai et al, 2015). Microalgae, as photosynthetic microorganisms, are recognized as potential feedstock for bio-SA production, offering an alternative to purified sugar derived from In this study, Response Surface Methodology (RSM) was applied, using R analysis to assess the impact of agitation rate and initial biomass feedstock concentration, along with examining their interactive effects on the production of bio-succinic acid (bio-SA) utilizing the Actinobacillus succinogenes strain.…”

This paper evaluates the potential of Chlorella sp. microalgae biomass as a feedstock for biosuccinic acid (bio-SA) production via the fermentation process. In this study, the biomass was pretreated and hydrolyzed using a mild acid before being fermented with Actinobacillus succinogenes. The influence of the initial biomass concentration and agitation rate on bio-SA production during batch fermentation was evaluated using a Response Surface Methodology (RSM) design. The results of the study indicated that Chlorella sp. microalgae biomass contained various types of sugars, with glucose identified as the dominant reducing sugar in the Chlorella sp. hydrolysate. According to the RSM analysis, the study showed that changes in the initial biomass concentration and agitation rate could significantly affect bio-SA production from Chlorella sp. hydrolysate. The highest bio-SA concentration of 14.56 g/L with a yield of 0.62 g/g was achieved when fermentation was performed using 10% (w/v) biomass at 150 rpm. Therefore, this study suggests that Chlorella sp. hydrolysate can be an alternative and renewable feedstock for efficient bio-SA production.
