“…For application as thermal insulation, non-woven structures were produced from silk cocoon waste (PCPIW), by needlepunching method. The samples as they have superior thermal insulation value (0.212 m 2 K/W) compared to commercial product, are good options to be used as environmentally friendly and low-cost thermal insulation materials, for the automotive, furniture and clothing industries (Kumar et al, 2022). Wazna et al prepared non-woven samples to produce insulation materials from PCPIW such as acrylic and wool, with fiber lengths from 40 to 50 mm.…”

Each year, millions of tons of clothing are both produced and discarded, exerting a substantial impact on the environment and public health. Even when textile waste is disposed of in landfills, it persistently adds to pollution in the air, water, and soil. This review explores the diverse implications of textile waste, examining circular economy principles and highlighting opportunities for transforming textile waste into eco-friendly materials. This review highlights opportunities to repurpose textile waste into new products, aligning with the principles of a circular economy. The discussed materials, such as cotton, wool, polyester, nylon, and kevlar, can be utilized in various industries, including construction, non-woven, furniture, carpet, agriculture, and paper. The alternative materials presented offer excellent mechanical, thermal, and acoustic properties, providing sustainable alternatives in applications ranging from civil construction to insulation and structure reinforcement, minimizing environmental impact. Green material alternatives enhance cost-effectiveness in constructing eco-friendly buildings, reducing the need for extracting new raw materials and minimizing the carbon footprint. It is expected that research on opportunities for recovering textile waste will soon intensify, leading to the implementation of these new eco-friendly products.

“…Vinoth et al developed a nonwoven textile by blending comber noil with silk cocoon waste, and found that the composite material has an increased thermal resistance of 0.212 m 2 •K/W due to the increase of porosity in nonwovens textile. 90 Mimicking the porous structure of polar bear hairs, Bai et al fabricated textile woven with the bioinspired silk fibers for thermal insulation. 14 The bioinspired silk fibers with tailored porous structures were fabricated by a "freeze-spinning" technique using natural silk as the raw material (Figure 10a− ).…”

The regulation and utilization of thermal energy is increasingly important in modern society due to the growing demand for heating and cooling in applications ranging from buildings, to cooling high power electronics, and from personal thermal management to the pursuit of renewable thermal energy technologies. Over billions of years of natural selection, biological organisms have evolved unique mechanisms and delicate structures for efficient and intelligent regulation and utilization of thermal energy. These structures also provide inspiration for developing advanced thermal engineering materials and systems with extraordinary performance. In this review, we summarize research progress in biological and bioinspired thermal energy materials and technologies, including thermal regulation through insulation, radiative cooling, evaporative cooling and camouflage, and conversion and utilization of thermal energy from solar thermal radiation and biological bodies for vapor/electricity generation, temperature/infrared sensing, and communication. Emphasis is placed on introducing bioinspired principles, identifying key bioinspired structures, revealing structure–property–function relationships, and discussing promising and implementable bioinspired strategies. We also present perspectives on current challenges and outlook for future research directions. We anticipate that this review will stimulate further in-depth research in biological and bioinspired thermal energy materials and technologies, and help accelerate the growth of this emerging field.
