In this work, a bimetallic Ni-Cu-BDC metal-organic framework system was developed via solvent thermal approach with using an organic ligand recycled from waste plastic. The physical properties of Cu-BDC and bimetallic Ni-Cu-BDC were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX) and N2 isotherms adsorption-desorption (BET).

The main objective of this study is to verify how social enterprises through recycling cooperatives are developing reverse logistics under the theoretical lenses of economic, social and environmental value creation in Brazil and Poland. For the accomplishment of this research qualitative approach was applied, and the method used was multiple case studies, where more than one object of study was considered, with an exploratory and descriptive nature.

For the past few decades to the era of industry 4.0, young practising designers have been enduring environmental communication challenges in the green manufacturing context. The problems stem from their failure to comprehend the pattern of environment communication phenomenally. The objective of this study is to address the environmentally-driven elements of recycling methodology along with the product’s form development via “re-think waste” of the environmental communications concept; screened by the bubbling model of intangible ecological form theory.

They present a scalable international solution to a global challenge; and are likely the only viable solution to the widespread lack of solid waste services and infrastructure across low- and middle-income countries. The article proposes using the environmental and wider risk posed by this pollution to target interventions to support these recyclers and benefit the environment.

Aquaponics combines two technologies, recirculating aquaculture systems and hydroponics in a closed system. The nutrients recycled from fish tanks supply nutrients for vegetables grown in hydroponics, however in some cases, the nutrient levels may not be sufficient for the optimal growth and yield of plants.

Recycling shrimp farming water is a way to address the trend toward a circular economy in Vietnam's coastal regions while also reducing the quantity of effluent that is released into the environment. In order to explore the potential for waste recycling, this study investigates the pond system of a highly intense Littopenaeus vannamei culture area in Ca Mau province.

The objective of this project was to develop \(Ti{O_2}\) based multifunctional substrates through silver decoration, while simultaneously enhancing the photocatalytic performance of \(Ti{O_2}\) in the substrate. Employing Ag nanoparticles introduced additional functionality to the system, namely surface-enhanced Raman scattering (SERS), thus enabling the detection of trace amounts of organic molecules prior to their degradation, all with the same substrate.

Aqueous sodium hydroxide solutions are extensively used as solvents for lignin in kraft pulping. These are also appealing systems for cellulose dissolution due to their inexpensiveness, ease to recycle and low toxicity. Cellulose dissolution occurs in a narrow concentration region and at low temperatures.

Two types of polymer-grafted silica based on polyvinylimidazole Brønsted acidic ionic liquids were prepared and used as new heterogeneous catalysts for the preparation of pharmaceutically important quinoxaline derivatives. These catalysts were characterized by thermogravimetric analysis, FT-IR spectroscopy, and titration. They could be recycled without considerable loss in their catalytic activity. High efficiency of the catalysts along with short reaction times, high yields, easy purification, recyclability, and simple procedure are among the advantages of these catalytic systems.

A highly dispersible and magnetically recoverable Cu-PEI@Fe 3 O4 MNPs catalyst was prepared and successfully applied in one-pot three-component coupling of terminal alkynes, sodium azide, and alkyl bromides/chlorides in water to give 1,4-disubstituted 1,2,3-triazoles with good to excellent yields. The catalyst was fully characterized with FT-IR, TGA, TEM, SEM, VSM, EDX, cyclic voltammetry, and ICP-AES spectroscopic techniques.
