“…After treatment, the supernatant is discarded and the solid residue left behind could be used in an undergraduate experiment to determine the identities of cations. Instead of having treatment steps being done by the staff, Nash et al 50 involve the undergraduates by having them treat the wastes chemically and remove zinc and copper as part of an experiment. The chemical treatment of different types of wastes can be studied in greater detail before implementing as part of the undergraduate experimental procedures.…”

A Study To Reduce Chemical Waste Generated in Chemistry Teaching Laboratories

Chemical waste should be reduced to minimize environmental pollution, and it is important that the amount of waste is minimized in chemistry teaching laboratories to reduce the negative impact on environment as well as the disposal costs of university. There are several ways to minimize the waste generated in chemistry teaching laboratories, namely, (1) elimination or reduction of the source of pollution, (2) recycling and reusing the chemicals, (3) treatment of waste to minimize its hazards, (4) the use of microscale chemistry, and (5) better management of chemical inventories in the laboratories. In this study, the common course syllabi and laboratory techniques of chemistry undergraduate experiments in universities are evaluated. The masses and volumes of chemical reagents used in the chemistry teaching laboratories of National University of Singapore (NUS) are quantified. Chemical waste reduction practices of the universities are examined, and a checklist is used to evaluate the current waste reduction practices in the chemistry teaching laboratories of NUS. Although there are existing practices that reduce the amount of chemicals used and waste generated in teaching laboratories, more effort could be done to improve the situation further.

Tasks that were presented to students regarding the topic 'pharmaceuticals in the environment' contributed to a better understanding of the possible risks of medical care on an introductory level. The tasks have been incorporated into a logic series of worksheets (Online Resource) with sample solutions available. Alternatively, the material would be appropriate for the preparation of a corresponding lecture on this topic.

“…Therefore, the strategy of transforming laboratory waste into porous materials such as zeolites, activated carbon, or MOFs for applications in catalysis, energy storage, and gas adsorption systems could be a topic of great interest and motivation for the students. − Literature revealed that previous attempts were made to introduce the synthesis of a MOF as a laboratory experiment. − In these experiments, MOFs were synthesized using various resources, including metals (Cr, Al, Zn, Mn) and di-, tri-, or multitopic organic linker sources (carboxylic acids) and explored for diverse applications. − For instance, Yaghi et al reported the synthesis of MOF-5 (metal, Zr; linker, benzene dicarboxylate) and MOF-808 (metal, Zr; linker, benzene tricarboxylate) in the laboratory and modified the textural properties of MOFs using reticular chemistry . In most of the cases, materials (resources) are purchased or synthesized, instead of being extracted from waste.…”

Lab Cooked MOF for CO₂ Capture: A Sustainable Solution to Waste Management

et al. 2020

To understand critical problems associated with solid waste and its consequences for the environment, a laboratory experiment is presented on the synthesis of aluminum-based metal−organic framework (MOF) MIL-53(Al) from household waste (PET bottles and aluminum foil/can), for undergraduate students of chemistry. This work is designed to teach students the research methodology and basic understanding of MOFs and their application in carbon capture and storage (CCS). Students also learnt several instrumentation techniques such as UV−vis spectroscopy, powder X-ray diffraction (P-XRD), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), and gas sorption to characterize the physicochemical properties of . The facile production of MIL-53(Al) enabled the students to investigate its applicability in CO 2 sorption. The calculations of essential parameters such as CO 2 over N 2 selectivity and the use of statistical tools in data processing are also explained to the students. In the end, the instructor presented his/her feedback by evaluating the answer sheets (pre-and postlab work) and by demonstrating the overall lab work through a model presentation.
