Polyethylene terephthalate (PET), the principal thermoplastic polyester derived from fossil fuels, is one of the most versatile plastics with vast applications in spinning, printing, the food business, the packaging industry, and electrical fields. PET waste's emissions of greenhouse gases have resulted in global warming, posing a significant ecological concern to humans, animals, and plants around the globe. The approach to achieving carbon peak emissions and carbon neutrality for PET polymers is depicted as CO2. It is indicated that the combination of recycling, biomass utilization, and carbon capture and utilization for PET plastics can be the optimal technique for achieving the set objectives. It would be desirable to achieve the objective of recycling 100% of PET trash and controlling and reusing CO2 emissions.

Abstract The influence of nanolignin coupling bio-agent on some characteristics of polypropylene-wood flour composites was studied. Thus, nanolignin was prepared by the acidic method, and then different ratios of it (0, 1, 3 and 5 wt%) were added to a polypropylene-wood flour mixture. After mechanically mixing wood flour, nanolignin, and polypropylene, the mixture was injection molded. ASTM methods were used to measure the structural properties of nanolignin, and prepared composites’ water absorption, thickness swelling, bending modulus, and bending, tensile and impact strengths. Transforming the original lignin to nanolignin did not change the chemical bonds of the material. The addition of nanolignin… More >

Abstract Greenhouse gas emissions from waste plastics have caused global warming all over the world, which has been a central threat to the ecological environment for humans, flora and fauna. Among waste plastics, waste polyethylene terephthalate (PET) is attractive due to its excellent stability and degradation-resistant. Therefore, merging China’s carbon peak and carbon neutrality goals would be beneficial. In this review, we summarize the current state-of-the-art of carbon emission decrease from a multi-scale perspective technologically. We suggest that the carbon peak for waste PET can be achieved by employing the closed-loop supply chain, including recycling, biomass utilization, carbon capture and utilization.… More >

Abstract Copper oxide nanoparticles (CuO NPs) were synthesised with laser ablation of a copper sheet immersed in deionized water (DW), cetrimonium bromide (CTAB), and sodium dodecyl sulphate (SDS), respectively. The target
was irradiated with a pulsed Nd: YAG laser at 1064 nm, 600 mJ, a pulse duration of 10 ns, and a repetition rate
of 5 Hz. The CuO NPs colloidal were analyzed using UV–Vis spectroscopy, the Fourier transform infrared (FTIR)
spectrometer, zeta potential (ZP), X-ray diffraction (XRD), transmission electron microscope (TEM) and field emission scanning electron microscopy (FESEM). The absorption spectra of CuO NPs colloidal showed peaks at 214,

Abstract Foam glass is a kind of green building material that is widely used because of its excellent thermal insulation and mechanical properties. In this study, the borosilicate foam glass was fabricated by powder sintering method using recycled soda lime waste glass, quartz, and borax as the primary raw materials. CaCO3 was used as a foaming agent and Na2CO3 as a flux agent. Results showed that as the quartz content decreases from 30 to 17.5 wt.% and borax content increases from 5 to 17.5 wt.%, the pore size, porosity, and thermal insulation of borosilicate foam glass increase significantly, while the compressive strength decreases… More >

Abstract Wood is a green material in line with the sustainable development strategy. From the excellent performance of
engineering wood products, modern wood structures represented by light wood structures have gained more
development opportunities. As an indispensable part of light wood structure systems, the wood-frame shear wall
plays a vital role in the bearing capacity and earthquake resistance of light wood structure systems. This paper is
focused on a review of the lateral performance of wood-frame shear walls and classifies the influencing factors in
relevant experimental research into three categories, including internal factors such as shear wall structure, external factors such… More >

Abstract Polyols are groups of organic compounds which contain carbon and are randomly linked to other atoms, especially carbon-carbon and carbon-hydrogen. These compounds are mainly used as reactants to make other polymers. Among biopolymers, lignin is regarded as the base of a new polymer in polyol construction. The present study aimed to investigate the effects of amine type (diethylenetriamine and ethylenediamine) on the modification of lignin-based polyols, so as to provide an alternative to petroleum polyols and, in turn, increase functional groups and reduce their harm to humans’ health and the environment. To this aim, first, lignin was extracted from raw… More >

Abstract Montmorillonite and clinoptilolite zeolite were used as representative materials to prepare calcined clay-cement
binary cementitious materials in order to study the effect of calcination treatment on the activation of clay minerals and the activity difference between layered and framed clays in this research. The influence of different calcined clay content (2%, 4%, 6%, 8%, 10%) on the fluidity, compressive strength, microstructure, phase change,
and hydration heat of cement-based materials were analyzed. The calcined clay improves the fluidity of
cement-based materials as compared with the uncalcined group. The addition of calcined montmorillonite
(CMT) improves the development of mechanical strength, and the… More >

Abstract To address the serious pollution of heavy metals in AMD, the difficulty and the high cost of treatment, Fe3O4-L was prepared by the chemical co-precipitation method. Based on the single-factor and RSM, the effects of particle size, total Fe concentration, the molar ratio of Fe2+ to Fe3+ and water bath temperature on the removal of AMD by Fe3O4-L prepared by chemical co-precipitation method were analyzed. Static adsorption experiments were conducted on Cu2+, Zn2+ and Pb2+ using Fe3O4-L prepared under optimal conditions as adsorbents. The adsorption properties and mechanisms were analyzed by combining SEM-EDS, XRD and FTIR for characterization. The study… More >

Abstract Lignin is a natural polymer, second only to cellulose in natural reserves. Degradation is one of the ways to achieve
the high-value transformation of lignin. Deep eutectic solvent (DES) thermal degradation of lignin can be used as
an excellent green degradation method. This paper introduces the degradation mechanism and effect of the lactic
acid-choline chloride DES system in dissolving and degrading alkaline lignin, and the final solvent recovery. It can
also be found from the scanning electron microscope (SEM) images that the surface of the degraded solid product
is transformed from smooth to disordered. Fourier transform infrared (FTIR) spectroscopy and… More >

Abstract Experiments of soiling effects on the performances of a PV panel have been performed using dust collected from two sites in the region of Agadir-Morocco. The optical transmittance of the front glass was found to depend on the nature and density of dust. The nature of dust was studied by means of scanning electron microscopy and energy dispersive x-ray spectroscopy. It was found that the granulometry of dust particles depends on the study area. For a dust density of around 20 g/m², the maximum power Pmax of the solar panel decreases drastically from 30 to 20 W for the (HP)… More >
