“…In order to do this, it is suggested that a circular economy should be integrated into our waste management system. A circular economy works as a holistic approach to recycling and waste management systems where production and consumption of goods involves the sharing, reusing, and repurposing of existing materials for as long as possible [7,40,56,59,60]. For example, within a circular economy, rather than incinerating or throwing plastic in landfills, it can be repurposed as plastic pellets.…”

“…General waste can also contribute to climate change through a multitude of processes. For example, organic waste-consisting of items such as kitchen waste, garden waste, and paper-accounts for over half of all waste [7]. When organic waste decomposes, much of which is done in dumpsites and landfills, carbon dioxide and methane gas are released into the atmosphere, contributing to global climate change [8,9].…”

Recycling and waste management have garnered immense popularity in recent years, but few studies have been carried out regarding these systems. Therefore, an in-depth literature review was done in order to highlight the different sectors of the recycling system that need to be reformed. Hence this study examined recycling and waste management systems within three categories–medical, municipal, and plastic–that were carried out pre and post COVID by reviewing previous studies, technical reports, and annual reports. This was done by visiting numerous academic search engines alongside online resources that were utilized to assemble literature related to waste and recycling systems. Continuing a recurring idea was that no matter the type of waste, further research regarding all waste should be carried out. Additionally, since recycling and waste management are a vital part of our society, and seeing how unpredictable events such as the pandemic may be, it is paramount that that research is done not only on how the pandemic has affected systems now, but also how we can learn from current issues to utilize them for future “waste shocks”.

“…Moreover, high-income countries generate around 34 percent of the world’s waste. Global waste generation is expected to increase to 3.40 billion tonnes by 2050 [ 2 ]. During the financial year 2018–2019, Australia produced 74 million tonnes of waste, a 10% increase since 2016–2017 [ 3 ].…”

Sustainable Cement Composite Integrating Waste Cellulose Fibre: A Comprehensive Review

et al. 2023

View full text Add to dashboard Cite

This review presents the research conducted to date in the field of cement-based composites reinforced with waste paper-based cellulose fibres, focusing on their composition, mechanical properties, and durability characteristics. The literature demonstrates that the properties of raw material (depending on their own chemical composition) significantly influence the formation of the cement composite binders. When considering fresh properties, the presence of silica and magnesium compounds generally lead to favourable effects on the setting of the cement composite when combined with waste paper cellulose fibre. Reduction in density values, i.e., approximately 25%, was observed with the inclusion of waste paper fibres from 20 to 80% in cement composites. The homogeneous dispersion of fibres in the matrix is one of the crucial factors to achieve in order to develop composites with well-balanced mechanical properties incorporating waste paper cellulose fibres. Hence, dispersion of fibres can be improved by increasing water quantity corresponding to the optimal value, which was a water/cement ratio of 0.64 leading to optimum strength properties of the composite. Even though the effect of fibre dispersion in the matrix improves with the addition of water, higher porosity and voids govern the strength properties beyond an optimum water-to-cement ratio. Higher porosity leads to an increase in the water absorption and a lowering of the thermal conductivity properties with the addition of paper fibre in cement binders. Paper fibre absorbs a high amount of water leading to higher water absorption. This phenomenon is related to the hydrophilic nature of cellulosic fibres absorbing some volume of water due to their microporous structure.

“…Looking for green and alternative approaches is an important way towards organic waste management and utilization, which will power our future with low-or zero-carbon emissions and strong sustainability (Liu et al 2012;Fang et al 2022). The resource utilization and harmless treatment of organic waste is an effective way to control environmental pollution, improve environmental quality, develop a circular economy, and achieve sustainable development (Kharola et al 2022;Peng et al 2022). To cope with the sustainable waste treatment and management, we organized this "Green utilization of organic waste resource" special issue with Environmental Science and Pollution Research to deliberate on global developments in the field of organic waste sustainable treatment and management.…”

With the development of economic levels, the proportion of the organic waste generated each year is increasing rapidly. It was believed that the annual outputs of crop stalks, livestock and poultry manure, and food waste have been reached more than 800, 2600, and 62 million tonnes in China, respectively (Liu et al. 2012;Niu et al. 2022;Wang et al. 2022). The excessive generation of this organic waste has resulted in serious socioeconomic and environmental problems worldwide, such as resource waste, environmental contamination, global climate change, and ecosystem degradation (Afolalu et al. 2022;Misslin et al. 2022). Looking for green and alternative approaches is an important way towards organic waste management and utilization, which will power our future with low-or zero-carbon emissions and strong sustainability (Liu et al. 2012;Fang et al. 2022). The resource utilization and harmless treatment of organic waste is an effective way to control environmental pollution, improve environmental quality, develop a circular economy, and achieve sustainable development (Kharola et al. 2022;Peng et al. 2022).To cope with the sustainable waste treatment and management, we organized this "Green utilization of organic waste resource" special issue with Environmental Science and Pollution Research to deliberate on global developments in the field of organic waste sustainable treatment and management. After a stringent peer-review process, 13 original research papers with high scientific levels were accepted for publication by Environmental Science and Pollution Research, mainly concerning the green utilization of organic waste resources.
