Different Composting Technologies
Organic waste management is a major global challenge. It accounts for a significant portion of waste that ends up in landfills, where it gradually decomposes and emits methane, a harmful greenhouse gas. Composting is the most preferred method for managing organic waste, as it applies to the masses, may not require significant areas, and of course, is capable of reducing the rate of the production of waste, while at the same time, producing valuable by-products, in the form of compost with potentially reducing the amount of greenhouse gas emissions, if done properly.

Lithium Recovery via Chemical Precipitation
Lithium is a vital raw material used for a wide range of applications, such as the fabrication of glass, ceramics, pharmaceuticals, and batteries for electric cars. The accelerating electrification transition and the global commitment to decarbonization have caused an increasing demand for lithium. The current supply derived from brines and hard rock ores is not enough to meet the global demand unless alternate resources and efficient techniques to recover this valuable metal are implemented.

Innovative Industrial Use of Bamboo
Industrial and service development has led researchers to focus on non-conventional materials with significant roles in innovation development and implementation. Entrepreneurs aim to develop innovative and creative strategies using good, valuable, durable, and sustainable materials that serve industrial and economic development. As result, the use of natural construction and production materials has increased interest related to the desire of developing greener and/or environmentally friendly processes. Several natural, re-emerging materials used in the past (e.g., bamboo, straw, reeds, and hemp) have been found useful again and deserving of research to fully understand their potential for different applications.

A Sustainable Circular Plastics Economy in The Netherlands
The circular economy (CE) has become a key sustainability discourse in the last decade. The Netherlands seeks to become fully circular by 2050 and the EU has set ambitious circularity targets in its CE Action Plan of 2015. The plastics sector, in particular, has gained a lot of attention as it is a priority area of both the EU and Dutch CE policies. However, there has been little research on the different and often contested discourses, governance processes and policy mechanisms guiding the transition to a circular economy and society. There is thus a dominance of technocentric imaginaries, and a general lack of discussion on holistic, and transformative visions, which integrate the full social, political, and ecological implication of a circular future.

Smart Glass
The term “smart window” was coined by Granqvist in 1985. From the early 1980s, smart glazing has been a rapidly developing innovative technology that is aimed to help manage energy transfer through the building’s envelope, evading unnecessary “cooling and heating of indoor air”. The use of smart glass, which helps to regulate the amount of light (and heat) entering a building, is one of the possible ways to reduce energy consumption in buildings while maintaining an appropriate level of comfort for users. Smart glass greatly influences the building envelope performance in (i) thermal management, (ii) daylight harvesting and regulation, (iii) reduction of glare, (iv) maintenance of views, (v) power capture, and finally (vi) activating the envelope as an information display. Some technologies are currently available on the market, although—in light of the many shortcomings of the existing solutions—smart glass is the subject of ongoing “intensive research aimed at improving the technology and its widespread use”.

Rotating Packed Beds
In this study, a comprehensive review was conducted of the process intensification equipment used for gas absorption processes, which are known as rotating packed beds (RPB) or HiGee contactors. Using centrifugal acceleration in RPBs intensifies the MT coefficient, and this leads to a reduction in the packing volume and energy consumption in comparison with packed beds. The gas velocity and flow area change radially in RPBs; therefore, MT coefficients change from point to point in contactors, but there is no general theory for this, and the prediction of MT coefficients in RPBs is theoretically complicated.

Plastic Waste Governance in Bangladesh
Plastic, an offer of modernity, is presenting a massive threat in altered forms, to our health and environment. Plastic does not only pollute the surface environment, fresh water, and marine ecosystems, but toxic elements released from plastics also percolate down the surface and contaminate groundwater, which we often use as ‘safe’ drinking water. This probable future risk is deeply rooted in the entire governance infrastructure of plastic waste which could potentially lead to contamination of groundwater. A recent study finds 81% of tap water samples collected worldwide contained plastic pollutants, which means that annually we may be ingesting between 3000 and 4000 microparticles of plastic from tap water.

Textile Recycling
Textile reuse consists of the various methods of prolonging the useful service life of textile products from one owner to another. Renting, trading, swapping, borrowing, and inheriting are commonly practiced, which are facilitated by second-hand stores, garage sales, online stores and flea markets, and charities. On the other hand, textile recycling refers to reprocessing pre-consumer and post-consumer textile waste for use in new textile or non-textile products. Various textile recycling technologies such as fiber regeneration, conversion of textile waste into insulation/building materials, fermentation, anaerobic digestion, composting, and thermal recovery are available and progressively improved. Textile reuse and recycling offer environmental sustainability and can reduce environmental impact by reducing the use of virgin textile fiber and avoiding processes further downstream in the textile product life cycle.
