This Special Issue on “Sustainable Composites with Solid Waste Materials” is a collection of 15 original articles (including one review paper) dedicated to theoretical and experimental research works, providing new insights practical findings in the field waste-related topics [...]
Municipal solid waste (MSW) management has emerged as an important human and environmental health issue. A large number of poor, downtrodden marginalized urban women are thriving on these recyclable wastes and are potentially exposed to a variety of occupational biohazards and safety risks. At present there are about millions of women in India who scavenge the city’s garbage bins and MSW dispos...
The environmental and social challenges of Solid Waste Management in developing countries have become an increasingly pressing issue. Disparities between the rich and poor continues to increase in many of these regions where growing urban areas often witness the worst signs of maltreatment of human labour and misallocation of waste as a resource. This thesis is a case study of the Municipality ...
Waste management is a strategic supply chain issue. This paper explores the definition and classification of waste from different viewpoints. A generic functional model is presented for modelling the material and flow of waste from both a physical and cumulative cost perspective. The application of the model is illustrated through a case study. The research demonstrates that improved waste mana...
Critical materials share the same insufficiencies in their life cycles; low recycling rates and a high degree of dissipative losses. The limitations for the secondary use of critical materials are their minor concentrations in final products, their dissipative applications, and the fact that they are irreversibly mixed with other material flows in current recycling practices. This is exacerbate...
Novel, functional materials based on chitin of marine origin and lignin were prepared. The synthesized materials were subjected to physicochemical, dispersive-morphological and electrokinetic analysis. The results confirm the effectiveness of the proposed method of synthesis of functional chitin/lignin materials. Mechanism of chitin modification by lignin is based on formation of hydrogen bonds...
