“…where P m is the modeled P load from SUMO, P r is the reported P load value from the literature, C scaled is the scaled specific consumption value for a chemical or energy, and C reported is the reported specific consumption value for a chemical or energy. Larger plants typically have lower specific energy and chemical consumption costs [46,47]. However, upscaling studies generally do not mention the specific chemical or energy consumption for various scales.…”

“…The sources of waste glass bottles include wine bottles, condiment bottles, and health product bottles. A variety of substances remaining in the glass bottles will dissolve in the washing water, forming organic wastewater containing a variety of organic substances. − About 0.4 tons of organic water is produced for the cleaning of every ton of waste glass, and therefore, additional wastewater treatment measures need to be taken for this wastewater. Reducing or eliminating wastewater generation is the focus of many recycling technologies. , In addition, the manual sorting process is inefficient, and the sorting process consumes a lot of manpower.…”

As a major part of municipal waste, the amount of waste glass has greatly increased. Due to its stable physical and chemical properties, glass can be effectively recycled with very little loss of quality. Meanwhile, recovery of waste glass is considered to be meaningful for saving resources and energy for sustainable development. However, remanufacturing processes always need a higher level of cleaning of waste glass. Traditionally, the combination technology of hydraulic cleaning and semimanual sorting is used to clean the organic and metallic impurities of waste glass. This combination technology has the disadvantages of low efficiency and producing lots of organic wastewater, which causes heavy environmental pollution. This study proposed an environmental-friendly combined recycling system of waste glass. Waterless cleaning, iron removing, eddy current separation, and optical separation were combined to realize the cleaning and sorting of waste glass. The operation parameters of each process of this new system were discussed and optimized. This system contributed to a high-efficiency and environmental-friendly way for the recovering of waste glass in municipal wastes, and it is an engineering practice to upgrade the urban solid waste recycling technology.

“…The production of acrylic acid in the pharmaceutical and fermentation industries produces large quantities of acetic acid wastewater annually . The content of acetic acid in these types of wastewater was usually lower than 5 wt %, but still very acidic and corrosive, which was mainly handled by neutralization or even burning . Thus, it is a desirable challenge to recycle acetic acid in low-concentration wastewater.…”

A series of alkoxy groups are introduced to the UiO-66 structure to enhance its adsorption performance toward acetic acid in water. The adsorption kinetics, isotherm, thermodynamics, and regeneration of these adsorbents have been investigated, and the excellent adsorption capacity of n-propyloxy-substituted adsorbent (UiO-66-3) is illustrated. The adsorption of acetic acid on UiO-66-3 was a complex multistep process, and the close contact between O of the ether bond of the adsorbent and H of the carboxyl group of acetic acid played an important role in adsorption. The kinetic results could be fitted well to the pseudo-second-order model. The adsorption isotherm followed the Langmuir isotherm, which indicated that the adsorption process involved a strong interaction between adsorbate and adsorbent. The thermodynamic parameters (ΔG, ΔH, and ΔS) had also been calculated, which verified that acetic acid adsorption on UiO-66-3 was a spontaneously endothermic process. The adsorbent exhibited good stability under specified experimental conditions, which consolidated its potential as a solution to wastewater containing dilute acetic acid.
