Article
A circular bioeconomy has the potential to minimize the environmental impacts of biowaste while simultaneously generating value-added bioproducts and bioenergy. Currently, most countries of the African Union lack well-defined policies, requisite infrastructure, and expertise for biowaste valorisation, thus limiting the potential development of the...

Purpose The olive oil sector in Italy has a significant socio-economic, environmental, and cultural relevance. However, the environmental impacts of production and consumption models are considerable, mainly due to the demand for large quantities of resources (fuels, chemicals) and to the environmental impacts of residues’ disposal. Due to the scar...
Article
In the last few decades, the rapid urbanisation process has led to an exponential growth of resource use, making increasingly difficult to ensure the principles of sustainability within urban systems. Similar to living organisms, cities have always required resources and energy to survive. However, technological development and population growth ha...
