In recent years, resource optimization has been recognized as a top priority among many challenges. Studies have indicated that valuable products can be created by combining natural or discarded resources with cutting-edge biosynthesis techniques. This approach is considered foundational for establishing a “zero-waste” socio-economic structure. This research focuses on optimizing resources and minimizing environmental impacts, especially within the manufacturing and fashion sectors. An innovative leather-like material named BC-BioLeath (Bacterial Cellulose-Based Bio Leather) has been introduced. BC was produced by the fermentation of coconut water, a byproduct of the food industry. Traditional leather-like processing, including tanning, was applied to BC using food waste such as oxidized edible oil and coffee grounds, along with timber industry by-products like vegetable tannins. Studies involving SEM observation, mechanical, style, and dyeing performance testing revealed that the product, BC-BioLeath, exhibited superior mechanical properties. For instance, BC crosslinked with oxidized edible oil showed a tensile strength of 82.14 MPa, surpassing traditional cowhide used in shoe uppers by 2.08 times. When plasticized with glycerol, the tensile strength reached 56.19 MPa, with breaking elongation of 36%. Beyond its mechanical prowess, the product also achieved economic and environmental benefits through waste repurposing, contributing to a natural energy cycle. BC-BioLeath was identified as a more humane and eco-friendly leather alternative. This method showcased not just efficient waste repurposing but also introduced a novel, microbe-focused sustainable production approach. Such a model offered a genuine circular economy solution for high-polluting sectors, such as the leather fashion industry. A cost analysis showed that BC-BioLeath's production cost of $97.92/m 2 (excluding labor and operating costs: $7.52/m 2 ) was within the commercial leather range of $39.7 to $220.8/m 2 . This indicated its sustainability as a competitive alternative.

The increasing amount of food waste and its sustainable management are gradually becoming global issues. The sustainable management of food waste has great potential benefits in terms of emission reduction and economic benefits. This study reports a novel environmentally friendly kitchen waste hydrogel synthesized from kitchen waste prepared from acrylamide, N,N ′-methylene bisacrylamide, Urea, and sodium persulfate by free radical cross-linking polymerization. Further, the effects of single factors on the solubility and mechanical properties of the hydrogel were investigated. Additionally, using a response surface methodology, the combined effects of the three key experimental parameters-cross-linking agent, temperature, and initiator were investigated on the mechanical properties of the hydrogel. The results revealed that at 64.83 ℃, the elastic modulus of the hydrogel reached 277.61 Kpa. The cross-linking agent and modifier amounts were determined to be 0.122 and 4.669 g, respectively. Subsequently, the mechanical properties of the kitchen hydrogels were researched by investigating the experimental mode of interaction between the experiment and molecular dynamics simulation. The simulation results were consistent with the experimental data, acting as a reference for the in-depth study of other properties of the kitchen hydrogel system. Graphical

Food waste is a kind of wet bio-waste which has been a challenge for the ecological environment and disposal. In this paper, hydrogen production from subcritical water gasification (SbWG) of food waste with and without catalyst loading was systematically investigated. The effects of reaction temperature (300–360 °C), residence time (30–90 min), food waste concentration (10–30 wt%) and catalysts (Ni/γ-Al 2 O 3 , Ni/ZrO 2 , NaOH, KOH, and FeCl 3 ) were studied within a pressure range of 10.5–20 MPa. The optimal process condition for SbWG of food waste without catalysts loading was determined to be 360 °C and 90 min with 10 wt% food waste. The liquid products and hydrochar were characterized by TOC , TGA/DTG, and SEM. The TOC concentration of liquid products decreased vastly with increasing reaction temperature. The highest H 2 yield (1.88 mol/kg), H 2 mole fraction (35.01%), and H 2 selectivity (53.86%) were achieved at 360 °C for 90 min with 5 wt% loading of KOH. It can be concluded that the performance of the catalysts for improving hydrogen production in SbWG of food waste was in the following order: KOH > NaOH > Ni/γ-Al 2 O 3 > Ni/ZrO 2 > FeCl 3 . The catalytic SbWG can be a potential alternative for energy conversion of food waste and hydrogen production.

Graphical HMF synthesis in NADES : High yield of 5-hydroxymethylfurfural (HMF) is obtained in a cheap and green natural deep eutectic solvent (NADES) system with a low amount of SnCl 4 catalyst from different biomass materials, including glucose, starch, and food wastes. The addition of water obviously improves the reactivity and economy of the NADES mixture. This is a green and efficient method to utilize carbohydrate resources for HMF production in a robust solvent system. 5-Hydroxymethylfurfural (HMF) has been regarded as an essential building block for synthesizing chemicals and biofuels, but the direct conversion of biomass to HMF is still a critical challenge. In this study, a cheap and green aqueous-natural deep eutectic solvent (A-NADES) was used to efficiently produce HMF from various carbohydrates, with a low amount of SnCl 4 as the catalyst. High HMF yields of 64.3, 64.0, 61.3, and 54.5 % were obtained from glucose, starch, rice waste, and bread waste at 130 °C in the A-NADES/MIBK (methyl isobutyl ketone) biphasic system, respectively. Mechanistic study results revealed that the water in A-NADES was the key factor in facilitating the conversion of Sn atom existent forms and promoted the HMF production. The choline chloride in NADES stabilized the HMF product with the cooperation of extraction solvent MIBK and inhibited the side reactions of HMF. This study investigated the multiple interaction functions of A-NADES to feedstocks and proposed a practical application of novel solvents to facilitate biomass and food waste conversion with a green method.

Capacitor deionization (CDI) technology has potential applications in heavy metal removal with low operating cost, environmental friendliness, and comprehensive benefits for water remediation. In this work, using food waste biogas residue as the carbon source, food waste biogas residue composite biochar with rich pore structure was prepared by adding tobacco stalk and KOH activation as the CDI electrode material, and Cu 2+ was taken as target pollutant for heavy metal removal studies. The pore volume of food waste biogas residue composite biochar with activation temperature at 600 ℃ was 2 times larger than that of food waste biogas residue and tobacco stalk biochar. The influence of temperature on structure, composition, electrochemical performance of biochar was further systematically investigated. Food waste biogas residue composite biochar with activation temperature at 800 ℃ (ABTC800) exhibited much larger specific surface area (2044.58 m 2 /g), abundant porous structure (1.29 cm 3 /g), and higher specific capacitance. The removal capacity of ABTC800 electrode can be up to 171.26 mg/g at 3 h in 50 mg/L Cu 2+ solution at a voltage of 0.8 V. Weak acidity is more favorable for Cu 2+ adsorption. ABTC800 had an excellent adsorption capacity towards Cu 2+ . In addition, characterizations revealed that Cu 2+ removal mainly relied on electrostatic adsorption, surface complexation, precipitation, and reduction during the whole process. This study proposed a promising strategy of biogas residue reuse for heavy metal removal.

The anaerobic digestion of food waste, can result in large amounts of solid waste digestate, often without methods of disposal. In this study, a biochar was prepared from food waste digestate (FWD) by pyrolysis, and its potential to activate peroxymonosulfate (PMS) for the removal of pollutants from a simulated textile wastewater was evaluated. The results showed that the addition of biochar (0.5 g/L) and PMS (1 mM) to wastewater could remove >99% of a representative azo dye pollutant (reactive brilliant red X-3B, 1 g/L) within 10 min. The efficiency of this removal process was attributed to the catalytic sites in the biochar (graphitic carbon and nitrogen, pyridinium nitrogen and C O structures) which could activate PMS to produce reactive oxygen species ( 1 O 2 , O 2 − , OH and SO 4 − ). The results obtained in this study confirmed the activation potential of the biochar derived from FWD on PMS, providing an alternative utilization strategy for anaerobic FWD.

Bioconversion of food waste into value-added products is a promising way to tackle the global food waste management problem. In this study, a novel valorisation strategy for bioenergy and lutein production via microalgal fermentation was investigated. Significant amount of glucose was recovered from enzymatic hydrolysis of food waste. The resultant hydrolysate was then utilised as culture medium in mixotrophic cultivation of Chlorella sp. to obtain high levels of lipid and lutein, whose accumulation patterns were consistent with molecular analyses. The resultant algal lipid derived from microalgal biomass using food hydrolysate was at high quality in terms of biodiesel properties. Further, in semi-continuous fermentation, the average algal biomass was 6.1 g L −1 with 2.5 g L −1 lipid and 38.5 mg L −1 lutein using hydrolysate with an initial glucose concentration of 10 g L −1 . Meanwhile, the resultant algal biomass was 6.9 g L −1 with 1.8 g L −1 lipid and 63.0 mg L −1 lutein using hydrolysate with an initial glucose concentration of 20 g L −1 , which suggests food waste hydrolysate could trigger algal products preferences. The experimental results of this study suggested the potential of microalgae as a platform for bioconversion of food waste into high-value products, especially sustainable bioenergy.
