Resources such as water, energy, and arable land represent bottlenecks with regard to achieving key sustainability paradigms such as the circular economy (CE). They exhibit vital inputs and outputs for economic development, ...

The treatment of different types of wastewater by physicochemical or biological (nonmicroalgal) methods could often be either inefficient or energy-intensive. Microalgae are ubiquitous microscopic organisms, which thrive ...

Current food and feed production practices via agricultural processes generate waste streams often rich in nitrogen. Conversion of the nitrogen in agricultural waste into valuable products would prevent environmental ...

Sludge is a heterogenous organic-rich matter that comprise of highly valuable biopolymers along with various contaminants including heavy metals. Sludge valorization as a renewable resource and inexpensive feedstock is key ...

Plastic is a commodity that supports our modern lifestyles. Its remarkable range of properties (e.g., durability, lightweight, good barrier properties) combined with the ease of processing make plastic a sustainable ...

The aquaculture industry is rapidly developing, generating a high amount of wastewater. Inland aquaculture effluents contain nutrients and other substances that can cause eutrophication and the emergence of resistive ...

The circular economy concept can enhance sustainability through restructuring consumption and production patterns using innovative designs and business models. This core premise is highly relevant for the interlinked water ...

The water-food nexus in the Middle East and Northern African (MENA) region is characterized by resource depletion, import dependence and environmental degradation. This contribution proposes that consumption awareness and ...

It has been estimated that the average Municipal Solid Waste (MSW) generation rate per capita in the Gulf Co-operation countries (GCC) is approx. 1.5 kg/person/d, with Qatar reaching almost 1.4 kg/person/d, as it was ...

© 2019 Elsevier B.V. Recycling of post-consumer plastic waste (PCPW) is increasingly promoted as the means to achieving circular economy (CE). It converts plastic waste into a secondary material that can be fed back into ...
