With the increase of waste paper, environmental pollution and atmospheric impact have become global problems. The cellulose contained in waste paper has the advantages of being renewable and biodegradable and can be applied to many fields to achieve sustainable development. At present, thermal management materials, as a new type of material, have…

As e-commerce increases, the demand for packaging materials and the potential for generating waste and negative environmental impacts also rise. Packing peanuts are a type of plastic packaging material that are used to protect goods during the shipping process. Petroleum-based plastics are common packaging materials due to their low cost, light…

Nowadays, discussing global environmental issues has become regularly included in STEM-based higher education, emphasizing the importance of the youth in finding "ad hoc" solutions for the climate crisis. One of the most commonly applied strategies is promoting sustainable choices among students, especially linked to their lifestyle…

We describe a guided-inquiry laboratory experiment for instrumental analysis in which our students test an improved protocol for the recycling of silver chloride to produce nontoxic waste. Students are provided with samples of silver chloride that they created as waste products in a previous lab experiment and tasked with performing a stepwise…

This article introduces a novel experiment that involves vitrimers, a new type of polymer, in polymer chemistry and physics lab courses for undergraduate students. Vitrimers are permanently cross-linked networks that can be reprocessed under certain external stimuli. Therefore, they combine the advantages of traditional thermoplastics (excellent…

A suitable combined laboratory experiment can involve more chemical disciplines and form students' views on practical connections. A laboratory experiment has been prepared focusing on the adsorption of the dangerous Co(II) ion using natural adsorbents representing waste material of a polysaccharide and keratin nature. Efficiency of Co(II)…

As environmental awareness grows, so do questions about the environmental impact of photography, in particular traditional film development and processing, which includes the use of plastics, gelatine and other environmentally harmful chemicals notwithstanding water usage and waste. Pioneering practice and research into sustainable alternatives to…

With the rapid growth in the manufacturing industry and increased urbanization, higher amounts of composite material waste are being produced, causing severe threats to the environment. These environmental concerns, coupled with the fact that undergraduate students typically have minimal experience in research, have initiated the need at the UAE…

A laboratory experiment was developed to introduce students to waste valorization. This is the process of reusing, recycling, or composting from wastes, useful products, or sources of energy. In this laboratory experiment, waste valorization is demonstrated through transforming waste orange peel (WOP) into a marmalade-type gel by extracting a…

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,…

Developing a broadly based positive culture of safety in undergraduate instructional laboratory settings remains a significant challenge for chemical educators. An enhanced safety component has been developed for an upper-level laboratory course based on earning a Chemical Hygiene and Safety badge. The badge requires student engagement in…

At many universities, silver nitrate is used in teaching laboratories, and a resulting waste product is often silver chloride. Silver chloride is not a compound that can be discarded into a sink as it has harmful effects to the environment; however, commercial waste disposal is costly, and replacement of the silver nitrate reagent is expensive.…

A practical approach for synthesizing functional material from waste material is described. The work was carried out by chemistry undergraduate students as a group project. The concepts used mainly in inorganic quantitative approaches were applied to transform an iron-containing material to magnetic iron oxide nanoparticles. The magnetic…

The aim of the research is the study of the chemical and phase composition of enrichment wastes of manganiferous ore in Ushkatyn-III deposit and the synthesis of new materials by mechanochemical activation and subsequent heat treatment of the mechanical activation products. The use of XFA, infrared spectroscopy and electron probe microanalysis…

Phosphates are essential components of any efficient fertilizer. Natural phosphate rock is, however, not available in every part of the world. According to the European Commission, phosphate rock has high economic importance as well as a certain supply risk--at least for Europe. For these reasons, environmental technology research has received a…
