Different Pathways to Integrate Anaerobic Digestion and Thermochemical Processes: Moving Toward the Circular Economy Concept

As one of the most environmentally friendly and cost-effective method, anaerobic digestion (AD) has been widely studied and developed as a conventional technology to degrade biodegradable materials and produce biogas simultaneously. Various substrate sources are used in this process such as organic fraction of municipal solid waste (MSW), waste activated sludge (WAS), animal manures, agro-indus...

Solid Waste Management in Ho Chi Minh City, Vietnam: Moving towards a Circular Economy?

The paper presents the current situation of the waste management system of the megacity Ho Chi Minh in Vietnam, and the options for waste and land recycling in a low income country. Generally, there is a large potential for circular economy in the city as the main proportion of the waste flows are recyclables. Due to the missing selective collection system, this potential is not used in the ful...

Toward Waste-Free Cloud Computing

Many previous efforts focus on improving the utlization of data centers. We argue that even highly utilized systems can still waste the resource because of failures and maintenance. Therefore, in this position paper, we call on a new direction of research on waste-free computing. We start with a workable definition of efficiency, then introduce a new efficiency metric called usage efficiency, s...

Consumers’ Perspective on Circular Economy Strategy for Reducing Food Waste

The current linear system of production and consumption is unsustainable. In the food sector, despite the fact that valuable natural resources are intensively used to produce and distribute food products, little is done to upcycle residues generated along the supply chain. Circular economy strategies are crucial for restructuring the take-make-dispose model through the active participation of a...
