Barriers to Textile Recycling in India
Post-consumer wastes from the textile industry are generally landfilled or incinerated. The dumping of large amounts of textile waste has resulted in severe environmental problems. Advancements in technologies have called for textile recycling; however, the level of embracement made by the textile industry towards textile recycling is hampered by myriad factors. Sstudy indicates a lack of successful recycling business models, poor demand for recycled textiles goods, recycled products may not replace new products, lack of support for waste management in the industry, and absence of tax relief and rewarding policies as the top five barriers to textile waste recycling. This insight could help influence the decision of future policymakers in the field. Another aspect of the issue of pollution in the textile industry is the recent trend of fast fashion and the enormous amount of waste produced by overconsumption. The Sustainability Development Goal (SDG) 12 which is to ensure responsible production and consumption plays a key role in this sector.

Thermal Energy Storage for Solar Plants
To address the growing problem of pollution and global warming, it is necessary to steer the development of innovative technologies towards systems with minimal carbon dioxide production. Thermal storage plays a crucial role in solar systems as it bridges the gap between resource availability and energy demand, thereby enhancing the economic viability of the system and ensuring energy continuity during periods of usage. Thermal energy storage methods consist of sensible heat storage, which involves storing energy using temperature differences; latent heat storage, which utilizes the latent heat of phase change materials; and thermochemical heat storage, which utilizes reversible chemical reactions through thermochemical materials.

Maintenance Strategies in Industry
Maintaining equipment in good condition is an important issue in the production process. Appropriate service and maintenance contribute to a high level of availability and reduce production downtimes. On the other hand, in power plants, maintenance costs represent a significant financial expense. Therefore, it is essential to achieve acceptable production results while optimizing service costs.

Integrated Optics: Platforms and Fabrication Methods
Integrated optics is a field of study and technology that focuses on the design, fabrication, and application of optical devices and systems using integrated circuit technology. It involves the integration of various optical components, such as waveguides, couplers, modulators, detectors, and lasers, into a single substrate. One of the key advantages of integrated optics is its compatibility with electronic integrated circuits. This compatibility enables seamless integration of optical and electronic functionalities onto the same chip, allowing efficient data transfer between optical and electronic domains. This synergy is crucial for applications such as optical interconnects in high-speed communication systems, optical sensing interfaces, and optoelectronic integrated circuits. This entry presents a brief study on some of the widely used and commercially available optical platforms and fabrication methods that can be used to create photonic integrated circuits.

Overview of Metal-Ion Battery Recycling Methods
Metal-ion batteries (MIBs), particularly lithium- and sodium-ion ones (LIBs and SIBs, respectively), are an essential part of portable and stationary electronics due to their energy density characteristics and long-term cycling ability. The expected growth of the MIBs market unavoidably leads to the generation of tons of spent batteries, this in turn dictates the necessity of a proper life cycle management of used cells and packs.
