Published: July 16, 2021

Population growth and the acceleration of urbanization have led to a sharp increase in municipal solid waste production, researchers sought use advanced technology solve this problem. Machine learning (ML) algorithms are good at modeling complex nonlinear processes been gradually adopted promote management (MSWM) help sustainable development environment past few years. In study, more than 200 publications published over last two decades (2000–2020) were reviewed analyzed. This paper summarizes application ML whole process MSWM, from generation collection transportation, final disposal. Through comprehensive review, gaps future directions MSWM discussed, providing theoretical practical guidance for follow-up related research.

Assessment of compost maturity-stability indices and recent development of composting bin

Energy Nexus, Journal Year: 2022, Volume and Issue: 6, P. 100062 - 100062

Published: March 28, 2022

Biological conversion of organic solid wastes to stabilized matter (OM) with high plant nutrient makes composting an ideal technique for managing waste. Present review summarizes the various bins manufactured around world that are used The knowledge about indices related process has become important and wider area research in current time. therefore focuses on stability maturity lays emphasis advantages uses matured compost. Composting useful converting compost at municipal level or home. Organic such as kitchen waste like food scraps, preparation residuals, etc. garden leaves, branches trees, grass clipping, etc can easily be converted into use these bins. This helpful conservation energy natural resource, reduce air water pollution help saving landfill space.

Heat potential, generation, recovery and utilization from composting: A review

Resources Conservation and Recycling, Journal Year: 2021, Volume and Issue: 175, P. 105850 - 105850

Published: Aug. 20, 2021

Composting is an effective process for treating organic solid waste (OSW). There a growing interest in recovering and reusing heat from composting, the context of climate change fossil fuel depletion. Several literature reviews have been conducted to address composting process; however, several engineering aspects, including estimation, recovery, utilization, are inadequately addressed current reviews. To fill this knowledge gap, we bring together on provide discussion methods calculating potential OSW, estimating amount production generated heat. Moreover, summarize utilization point out challenges outlook future research. The results show that heating value different OSW can be calculated by ultimate analysis, proximate or composition analysis. used estimation: degradation method adequately describe process, O2 simpler implement, balance only valid at large scale reactors. Different types reactors use techniques recovery: water jacket suitable small-scale reactors, while tube buried-in pile percolation especially lignocellulosic biomass composting. Heat exchanger head space low-temperature recovery technologies mainly commercial recovered potentially building applications such as hot service, flooring wall heating.

Composting of Organic Solid Waste of Municipal Origin: The Role of Research in Enhancing Its Sustainability

International Journal of Environmental Research and Public Health, Journal Year: 2022, Volume and Issue: 20(1), P. 312 - 312

Published: Dec. 25, 2022

The organic solid waste of municipal origin stands as one the residual streams greatest concern: great amounts continuously produced over time well its biochemical and physical characteristics require proper handling via biological processes, pursuing recovery material and/or generation energy. At European level, most industrial plants treating fraction (OFMSW) rely on composting, which is a well-established reliable process that easy to operate in different socio-economic contexts. Nevertheless, when regarded life cycle perspective view principles circular economy underlying management, several issues (e.g., presence toxic substances compost) can be recognized technical challenges, requiring further studies identify possible sustainable solutions. This work aims at discussing these challenges figuring out state art composting perspective. Firstly, main mentioned affecting compost quality sustainability are briefly reviewed. Next, promote effective use light principles, research experiences critically presented highlight current concerning environmental health impact reduction scientific perspectives overcome quality. Based critical analysis reviewed studies, it emerged should aimed unveiling hazard potential emerging contaminants address understanding mechanisms their removal during composting. Moreover, adoption multidisciplinary design may play key role towards definition cost-effective environmentally friendly strategies process.
