npj Materials Sustainability, Journal Year: 2024, Volume and Issue: 2(1)

Published: April 8, 2024

Abstract Data-driven modeling is being increasingly applied in designing and optimizing organic waste management toward greater resource circularity. This study investigates a spectrum of data-driven techniques for treatment, encompassing neural networks, support vector machines, decision trees, random forests, Gaussian process regression, k -nearest neighbors. The application these explored terms their capacity complex processes. Additionally, the delves into physics-informed highlighting significance integrating domain knowledge improved model consistency. Comparative analyses are carried out to provide insights strengths weaknesses each technique, aiding practitioners selecting appropriate models diverse applications. Transfer learning specialized network variants also discussed, offering avenues enhancing predictive capabilities. work contributes valuable field modeling, emphasizing importance understanding nuances technique informed decision-making various treatment scenarios.

Sustainable energy generation from municipal solid waste: A brief overview of existing technologies

Case Studies in Chemical and Environmental Engineering, Journal Year: 2023, Volume and Issue: 8, P. 100491 - 100491

Published: Sept. 16, 2023

The aim of this mini review is to outline the currently existing methods energy recovery from municipal solid waste (MSW), including incineration, pyrolysis, anaerobic digestion, and landfill gas utilization providing tentative suggestions for further research. Through a comparative analysis these technologies, paper evaluates their feasibility in context MSW management presents current research related technologies. Incineration capture emerge as most prominent options waste. effectively reduces volume generates electricity heat, while uses methane emissions decomposition landfilled generate reduce environmental impact. Pyrolysis digestion on other hand have limited use obtaining due complex processes challenges associated with heterogeneous composition there are still problems that needs be addressed before successful industrial scale applications. In addition, analyses thermal treatment hierarchy. This underscores importance matching technology choices characteristics highlights tailored approaches general Waste-to-Energy projects particular.

Carbon footprint assessment of water and wastewater treatment works in Scottish islands

Journal of Cleaner Production, Journal Year: 2024, Volume and Issue: 450, P. 141650 - 141650

Published: March 4, 2024

Quantifying the global warming potential of existing water infrastructure is an important step in realising industry's commitment to net-zero carbon. Whilst there has been improved understanding centralized urban infrastructure, rigorous analyses smaller-scale rural systems are rare. This work adopts a life cycle assessment ascertain drinking treatment works and wastewater associated with five Scottish islands: Arran, Iona, Jura, Barra, Vatersay. The systems, from source sink, along use chemicals, transportation, energy, disposal waste products considered. potentials island's ranged 0.18 0.79 kgCO2-eq/m3 water, while that for were 0.51–1.14 wastewater. services on islands can be as much 7 times across Scotland previously reported. Major contributor was electricity consumed by membrane bioreactor. modelled direct emission methane sludge septic tanks landfill made largest contribution potential. It also highly sensitive model parameters, which highlights need comprehensive exploration process emissions handling. analysis baseline against alternative low-carbon technology configurations compared.

The potential of insect frass for sustainable biogas and biomethane production: A review

Bioresource Technology, Journal Year: 2024, Volume and Issue: 412, P. 131384 - 131384

Published: Aug. 30, 2024

Insect-based protein production has gained traction in recent years. This led to the increasing of frass, residual substrate from insect farming. As a relatively new with characteristics that are not widely known, its energetic potential still needs be investigated. In this context, literature review aims evaluate frass as feedstock for bioenergy through anaerobic digestion. From search, 11 studies were selected, and showed wide range biogas (44 m
