“…Additionally, the measured value does not differ much from those obtained for conventional thermal insulation materials used in buildings such as rock wool, glass fiber, expanded polystyrene (EPS), and polyurethane foam (PUR), whose thermal conductivities generally range from 0.022 to 0.042 W/mK [28,32,39].…”

Exploring new construction materials with low environmental impact leads to innovation in buildings and also to the expansion of environmental sustainability in the construction industry. In this perspective, the thermal insulation and the sound absorption performances of Buriti (Mauritia flexuosa) foam were analyzed for potential application in buildings. This material is of plant origin, it is natural, renewable, abundant, and has a low environmental impact. In this research, characterizations were made by scanning electron microscopy (SEM), apparent density, thermogravimetry (TGA and DTG), thermal conductivity, and sound absorption. The SEM analysis revealed a predominantly porous, small, and closed-cell morphology in the vegetable foam. Due to its porosity and lightness, the material has an apparent density similar to other thermal insulating and sound-absorbing materials used commercially. The evaluation of thermogravimetric (TGA/DTG) results demonstrated thermal stability at temperatures that attest to the use of Buriti foam as a building material. Based on the thermal conductivity test, the Buriti foam was characterized as an insulating material comparable to conventional thermal insulation materials and in the same range as other existing thermal insulators of plant origin. Concerning sound absorption, the Buriti foam presented a low performance in the analyzed frequency range, mainly attributed to the absence of open porosity in the material. Therefore, understanding the sound absorption mechanisms of Buriti foam requires further studies exploring additional ways of processing the material.

“…These fibres are categorized into three types based on their extraction source: mechanical, ribbon, and xylem. The mechanical fibres exhibit the highest strength, while xylem fibres possess the lowest strength [98]. In the study conducted by Santos et al (2009), nonwoven sisal fibres were manufactured by a needle-punch process and then cold-treated with 2 wt.% NaOH solution [98].…”

There has been a growing interest in recycling and upcycling different waste streams due to concerns for environmental protection. This has prompted the desire to develop circular economies and optimize the utilization of bioresources for different industrial sectors. Turning agricultural and forestry waste streams into high-performance materials is a promising and meaningful strategy for creating value-added materials. Lignocellulose fibres from plants are emerging as a potential candidate for eco-friendly feedstock in the textile industry. Nonwoven fabric is one of the most innovative and promising categories for the textile industry since it currently utilizes about 66% synthetic materials. In the upcoming wave of nonwoven products, we can expect an increased utilization of natural and renewable materials, particularly with a focus on incorporating lignocellulosic materials as both binders and fibre components. The introduction of low-cost fibres from waste residue materials to produce high-performance nonwoven fabrics represents a shift towards more environmentally sustainable paradigms in various applications and they represent ecological and inexpensive alternatives to conventional petroleum-derived materials. Here, we review potential technologies for using agricultural waste fibres in nonwoven products.
