As society changes, new ways of understanding and using existing semiotic resources are needed. This study looks at artefacts from a social semiotic perspective in order to explore the concepts of ‘recycling’ and ‘upcycling’ and their relevance for pedagogy in Higher Education. We look at recycling in terms of ‘texts’ and employ methodological tools from multimodal discourse analysis. ‘Recyclin...

Product functions, assembly and disassembly processes largely depend on the connections that are holding the product’s components together. In general, the disconnecting process of established connections is sub-optimal, which often remains unnoticed until maintenance or recycling requires disassembly work. Sometimes connections were optimised to improve the disconnecting processes, but usually...

Despite the enormous efforts devoted to high-performance lithium-ion batteries (LIBs), the present state-of-the-art LIBs cannot meet the ever-increasing demands. With high theoretical capacity, fast ionic conductivity, and suitable charge/discharge plateaus, Li3VO4 shows great potential as the anode material for LIBs. However, it suffers from poor electronic conductivity. In this work, we prese...

Modern production conditions demand the application of the concept of distributed production. Today companies are specialized for partial technology processes. Hundreds, sometimes even thousands, of collaborative processes depend on workers’ interaction and communication in product assembly and disassembly phases. RFID technologies can be really helpful in identifying objects in terms of sustai...

Over the years, petrochemical industry has developed a plethora of polymers that are contributing to well-being humanity. Irresponsible disposal used plastics has, however, led buildup litter, which is fouling environment, harming wildlife, and wasting valuable resources. This paper critically reviews challenge opportunities in converting plastic waste into feedstock for industry. It discusses ...

The cell-free biocatalytic production of fine chemicals by oxidoreductases has continuously grown over the past years. Since especially dehydrogenases depend on the stoichiometric use of nicotinamide pyridine cofactors, an integrated efficient recycling system is crucial to allow process operation under economic conditions. Lately, the variety of cofactors for biocatalysis was broadened by the ...

Lithium-ion batteries (LIBs) are a key technology in decarbonizing the transportation and electricity sectors, yet use of critical materials, such as cobalt, nickel, lithium, lead to environmental social impacts. Reusing, repurposing, recycling mitigate battery impacts by extending their lifespan reducing reliance on virgin materials. Innovation that reduces demand for these problematic materia...

In the present study, struvite decomposition was performed by air stripping for ammonia release and a novel integrated reactor was designed for the simultaneous removal and recovery of total ammonia-nitrogen (TAN) and total orthophosphate (PT) from swine wastewater by internal struvite recycling. Decomposition of struvite by air stripping was found to be feasible. Without supplementation with a...

Abstract In this work, a novel Ni/ZnO-MnO2 electrode was fabricated by utilizing spent zinc-manganese batteries and then applied to the electrochemical treatment of ammonia-containing wastewater. The obtained characterized scanning electron microscopy, X-ray diffraction, linear voltammetry, suggesting that had flower-like structure showed high oxygen evolution potential activity. performance Zn...

Ad-hoc recycling between requirements documents of product variants is a major source of requirements defects. In this paper, we present an approach for systematic requirements recycling based on a combination of abstraction (in terms of a template) and traceability (between requirements). The main features of our approach are the use of conceptual models to determine relationships necessary fo...
