The International Association for Advanced Materials is optimistic that the United Nations' Sustainable Development Goals (SDGs) can be achieved through scientific consideration of circular materials and embracing new green technological advances, as well as by keeping global commitments to reduce climate change, adapt to it, and come up with new ways to deal with it. The present green transition projects rely heavily on the accessibility of biodiversity, climate, and net-zero technologies leading to a sustainable future. A sustainable and green world refers to a global society that operates in harmony with nature, respects ecological limits, and ensures social and economic well-being for present and future generations. It is characterized by responsible resource management, reduced environmental impact, social equity, and the protection of ecosystems. In the context of effective climate resource management, it is necessary to recognize the value of natural materials and incorporate them into ongoing practices and processes. Understanding materials selection, along with leveraging nature-based solutions and renewable technologies, plays a significant role in driving the world's circular economy while ensuring sustainability. Addressing pollution, reducing reliance on non-renewable energy sources, adopting low-carbon materials, and eliminating plastics and harmful chemicals are essential steps toward creating a circular market that connects materials in a circular manner. This approach aligns with SDGs along with the Conference of the Parties (COP), and European Green Deal (EGD), which also emphasizes sustainability, net-zero, and circular processes. In this quest, advancements in climate-efficient materials science and technology, coupled with waste resource innovations, have potential usefulness towards all-in-one green solutions. Thus, it is crucial for the research community to focus on green R&D practices, and topical consortiums as much as possible. By prioritizing climate-efficient materials, promoting sustainable practices, and fostering innovation, the advanced materials world community can work towards materials development goals for a sustainable and green world.

This paper studies human exposure to microplastics in real-life situations. The concentration of the polyamide nano/microplastics in the proximity of textile workplaces was made by the device Laser Aerosol Spectrometer. The descriptive statistical analysis was elaborated for: variables TSC (total concentration µg/m3), PM10 (µg/m3), PM2.5 (µg/m3), PM1 (µg/m3) and TC (total number of particles, 1/l). The histograms of each variable highlight the asymmetry of the distribution, with the predominance of frequencies or variables; representation of level indicators (average, median) and dispersion-box-plot graphs were obtained. Collection of the particle made with TECORA-SKYPORT PM-HV and GilAirPlus pumps, by using Quartz and Nucleopore filters with different diameters highlighted that the highest mass (683µg) was collected by using GilAir Plus pump and Quartz filter 37mm. A strong correlation was obtained between the variable: "Collected mass/ Air concentration": r = 0997775 ÷ 0,999477 and "Collected mass/ Air volume", r = -0,97473 ÷ 0.80064. The prediction of the value of the collected mass as a function of the diameter of the filters, particle concentration, airflow, and total air volume was made by obtaining the regression equations. Optic microscope analyses highlighted the dimension of microfibres (50% are <10µm) and SEM the dimension: 25% < 68.47 nm and the spherical shape of particles. FT-IR, µRaman and TG-DSC analyses showed the presence of PA particles in the collected particles.

This paper presents the polypropylene (PP) micro-nano particles (MNPs) exposure routes of textile industry personnel and analyses the characteristics of such particles collected in and outside the workplaces. A Laser Aerosol Spectrometer set was used to determine: the total suspended particles (TSP), PM10, PM2.5, PM1 fractions (µm/m3), and the total number of particles (TC) (1/l) from the air. Specific methods for descriptive statistics were used to characterize the particle populations. Mean, dispersion and standard deviation, median and quartiles, skewness and kurtosis for asymmetry, and highlighting the cases in which they should be performed were calculated. The box plots and histograms graphs for TSP, PM10, PM2.5, and PM1, TC variables. The comparative analysis of the results led to the identification of the fraction of the particles with the highest value concentration in the air. The particles were collected on quartz and polycarbonate filters with gold membrane using TECORA and GilAirPlus pumps. The mass of particles collected was determined by weighing the filters before and after collection, using an electronic balance. Characterization of PP dust collected by analysis: Optical microscope, Scanning Electron Microscopy, µRaman spectroscopy, FTIR, and TG-DSC allowed the identification of the shape, size, and structural footprint of PP particles.

The intertidal clam, Glauconome virens, was collected in the northwestern portion of Peninsular Malaysia near Kuala Perlis, Sungai Layar, and Pantai Teluk Air Tawar. This research attempted to determine the cadmium (Cd) and lead (Pb) concentrations in the various G. virens’s organs. The Cd concentrations (mg/kg dry weight) in five distinct soft tissues ranged from 0.90 to 1.89, but the concentrations in shells ranged from 0.95 to 1.25. Pb concentrations (mg/kg dry weight) in the five distinct soft tissues ranged from 27.0 to 44.9, whereas shell concentrations ranged from 74.8 to 75.3. In general, the shell had more Pb than the soft tissue components. Future biomonitoring research on this type of clams should concentrate on certain tissues (such as the remainder, shell, and gill) to identify their potential as biomonitoring organs/materials. This biomonitoring study is of paramount importance to establish the intertidal clams as a good biomonitor under the umbrella of International Mussel Watch. Besides, establishment of such biomonitoring baseline data is important for future references and human health risk assessments.

Climate neutrality has turned out to be crucial in policy and state relationships. In lines of green actions, many capitals have declared aspiring climate neutrality goals to establish their net-zero infrastructures and inhabitants. The increasing emission of greenhouse gases paves the way to enhance the earth temperature, which are resulting to endangering lives mainly due to dry up of water reserves. Thus, abrupt climate change is adversely affecting the world-wide ecosystems and biodiversity. The common effects of climate change are causing through droughts, forest fires, cloudbursts, cyclones, earthquakes, heavy rains, snow, cold and hot waves etc. From north to south America and from east to west Asia are experiencing frequently extreme weather events. This interns to fast moving of the global warming. The impact of extreme weather conditions needs to urgently normalise with adopting ecological practices, green scientific protocols, time bound government strategies and comprehensive climate actions.

Climate change is evolving as the major concern of erratic weather conditions for example heavy rains, drought floods, landslides, soil erosion, tsunami, and extreme cold and warm weather, which severely impact the livelihoods of mankind. Attaining the substance by reducing carbon pollution and other greenhouse gases is the best way to control climate change. Considering the suitable climate, habitat variation, and their adverse effects such as glaciers, heatwave, sea levels rise, etc., it is important to understand the climate control and framing combat policy as per the requirement of energy. Hydrogen is now established as a clean and flexible energy carrier. Europe and the other nations are progressively walking toward achieving the net-zero objective with the overview of clean hydrogen energy, which will ensure global sustainability faster.

The present study is aimed to remove toxic crystal violet dye from aqueous solutions. In this study guar gum (GG) has been grafted with acrylic acid (AA) by following microwave assisted grafting method. Two different nanomaterials i.e., nanoclay (NC) and multiwalled carbon nanotubes (MWCNT) has been incorporated either alone or in combination during the grafting reaction. The synthesized nanocomposites have been used for removal of crystal violet dye from aqueous solutions. Study showed higher dye adsorption capacity of the synthesized composites after addition of nanomaterials. The adsorption isotherm followed both Langmuir and Freundlich model. It was found that GG grafted AA composite with MWCNT showed highest crystal violet dye adsorption compared to others. Swelling behaviour of the synthesized composites in acidic, neutral and alkaline medium has been studied. The swelling kinetics in acidic, neutral and alkaline medium was found to follow pseudo second order kinetic model with <R2> value more than 0.98. Fourier transform infrared spectroscopy (FTIR) showed efficient grafting of AA on GG. X-ray diffraction (XRD) and morphological characteristics depicted enhanced dispersion of nanomaterials in GG matrix.
