“…Some of the materials investigated so far have included ground granulated blast furnace slag [ 15 , 16 ], mixtures of fly ash and slag [ 17 , 18 , 19 ], pre-treated wood biomass ash and diatomite [ 20 ], red mud [ 21 ], cement kiln dust and feldspar [ 22 ], lithium slag [ 23 ] and mining residues [ 24 ]. However, with the amount of 550–750 Mt/year of extractive waste generated in Europe [ 25 ] and the new European regulations encouraging the reuse of industrial side streams instead of landfilling [ 26 ], further research should aim to find industrial applications for these different side streams of extractive waste.…”

Effect of Sodium Disilicate and Metasilicate on the Microstructure and Mechanical Properties of One-Part Alkali-Activated Copper Slag/Ground Granulated Blast Furnace Slag

Copper slag (CS) remains a challenging industrial by-product with a relatively small utilization fraction. The present study investigated the development of one-part alkali-activated cements based on CS, ground granulated blast furnace slag (GGBS) and a mixture of the two as a precursor. We investigated 5 to 15 wt% solid sodium metasilicate (Na2SiO3) and disilicate (Na2Si2O5) as alkaline reagents. Isothermal calorimetry showed that the reactivity of the system was higher for the metasilicate based samples, with early reaction and higher cumulative heat released. Metasilicate based samples also presented a more densified microstructure, lower porosity and higher strength. Better performances were observed with 10 wt% metasilicate/disilicate with respect to the 5 and 15 wt%. The 28-day compressive strength and elastic modulus of 10 wt% metasilicate samples reached 75 MPa and 25 GPa, respectively, and, for paste samples, ranged from 100 wt% GGBS to 50/50 wt% CS/GGBS. The microstructure and calorimetry of the pastes showed that GGBS actively participated in the binding process, whereas CS played a smaller role and acted as a filler and catalyst. The substitution of commercial GGBS by CS up to 50 wt% did not affect the overall performance, thus, bringing CS forward as an economically interesting precursor.

“…Indeed, active treatment methods have been intensively investigated since 99% of metal recovery can be achieved. , Among these methods, membrane processes have stood out as emerging techniques for AMD remediation because it is possible to obtain high-quality water and concentrating the heavy-metal portion with low energy consumption. For this reason, membrane technologies are chosen as best available technologies for waste management from extractive industries, in agreement with the European Commission …”

In this work, a novel study for acid mine drainage remediation and reutilization by means of a forward osmosis technology is addressed. The proposed process is a potential alternative path, which allows to recover high-quality water and to concentrate metals for its possible reutilization as synthetic minerals. This novel process will help in the mining industry evolving toward more sustainable processes and favors circular economy policies. Four inorganic salts (NaCl, KCl, CaCl 2 , and MgCl 2 ) were evaluated as draw solutions from 1 to 5 M concentrations, in terms of water flux, water recovery, and metal rejection, using a thin-film composite (TFC) membrane. Water flux obtained was in the range of 14−53 L/(m 2 h). The highest water flux was found for MgCl 2 , whereas the lowest correspond to KCl. The metal rejection obtained was greater than 99%. After a discussion and comparison of the results, MgCl 2 was chosen for evaluating long-term assay performance. Scanning electron microscope images of the thin-film composite membrane after long-term assays were taken. The tendency of Mg−Ca and Al−Fe fouling was observed over the membrane surface. The energy consumption was estimated from 4.84−22.3 kWh e /m 3 , assuming that osmotically assisted reverse osmosis is used to regenerate the draw solution.

“…Organic MSW is thrown into the garbage chute, the rest of the waste is sorted either by containers installed in basements, or special containers for various garbage are made in the garbage wire. If the residents of the house refuse to sort MSW, a fine is charged, which covers the sorting of MSW at garbage stations [27,28].…”

The article discusses the main directions of improving the management of municipal solid waste in accordance with the requirements of the concept of sustainable development. The concept of “solid municipal waste “is analyzed in its comparison with the concept of “solid household waste”. The problems associated with the functioning of the sphere of solid municipal waste management are emphasized. The tasks of the development of this industry for Russia in the near future are defined. Environmental control of MSW is difficult, since the main sources of MSW are households and organizations of municipal services of settlements. These sources are numerous, highly dispersed (scattered throughout the territory). Insufficient eco-cultural training and inadequate self-awareness of the population prevent the regulation of MSW flows and the spread of SD in everyday life. Therefore, the solution to the problem of solid waste should use an adequate methodology, including administrative regulation and systematic improvement of the level of ecological culture of the population.
