“…It is therefore mandatory to look for renewable energy sources able to replace coal and oil, especially in buildings that consume about 30-40% of the world's energy to ensure a healthy and comfortable space. Similarly, the energy efficiency of buildings has started to gain enormous significance in order to contribute to the reduction of the pressure on the environment by inserting ecological and recyclable thermal insulation throughout their life cycle (Adamczyk and Dylewski, 2017;Philip and Rakendu, 2020;Pal et al, 2021;Füchsl et al, 2022). Currently, the thermal insulation of buildings is ensured by non-renewable synthetic inorganic materials such as glass and rock fiber, mineral wool, and so on (Patnaik et al, 2015).…”

The intercalation of polyethylene glycol (PEG) chains, in the inter-layer environment of the clay from Meknes, was performed using the direct intercalation method in the presence of water as a solvent. X-ray diffraction (XRD) technique was applied to follow the evolution of interlayer distances as a function of PEG bulk volume fraction. The XRD data assert the formation of an intercalated structure through the displacement of the peaks, which characterize the clay minerals towards the small and large angles. The evolution of the d001-spacing for the three classes of clays was similar. Indeed, as φ increases, the d001 variation is marked by two depletion phenomena due to the magnitude of the gyration radius compared to the inter-layer distance of the clay minerals. The plateau regime, characterized by the weak insertion of the chains, appears after each depletion/expansion cycle, which reveals a succession of the depletion-adsorption-plateau phenomenon. Based on the results of the XRD method, we proposed a model for the insertion of PEG chains in monolayer and bilayer forms into the interlayer environment of clay minerals. Finally, the scaling theory reveals a good agreement with the experimental findings and perfectly illustrates the succession of three regimes: dilute, bidimensional semi-dilute, and plateau.

Current insulation materials applied in construction engineering and the building industry are generally petrochemical-based polymers and recycled thermal insulation materials. The environmental effects of these materials’ production processes are substantial, despite their high thermal insulation performance. Consequently, the researchers conclude that it is essential to develop and produce insulating materials with superior thermal properties, minimal environmental impact, and a reasonable cost. The study concentrated on the application of insulation materials derived from biomass in the development of thermal insulation. The purpose of this review is to investigate and develop the possibilities of using biomass wastes as renewable and eco-friendly thermal insulation materials for construction engineering and the building industry. The thermal conductivity of those materials was measured using the hot plate and hot box methods, two of the most widely used hot processing methods. With a relatively low thermal conductivity (< 0.100 W·m−1·K−1), this review provides critical scientific insight into potential building insulation materials derived from biodegradable and abundant resources. It was observed that these materials are appealing for use in building and construction because they have a number of potential advantages from technical, economic, environmental, and green credentials perspectives. The collection of information enables some conclusions regarding the different biomass waste–derived insulation materials that have already been investigated and identifies gaps in the literature. Finally, the scope of commercialization pathways and future research directions to validate the proposed material alternatives’ claim for commercial-scale applications has been identified in this review.
