Therefore, the present study examined 17 sewage sludges from municipal wastewater treatment plants in Lower Silesia for energy properties and mercury content before and after the following technological processes: autothermal aerobic stabilization at temperatures above 50 °C (ATSO), aerobic separated stabilization at effluent temperature (KTSO), separated digestion at ambient temperature (OKF) and separate digestion at 37 °C (WKF). The study showed that the mercury content ranged widely from 0.47 to 6.05 mg/kg Hg, indicating several times higher atmospheric emissions than when using conventional fuels.

This systematic literature review highlights the research carried out on this topic over the last two decades and discusses industry practices in producing PVC flex banners, the environmental impact of PVC flex banners due to annihilation, and reuse and recycling methods for PVC flex banners. One of these opportunities is upcycling, which is an important part of the reuse strategy. These flex banners can be reused in the fashion industry as upcycled products [high-value functional and aesthetic products] and accessories through zero-waste fashion production processes [especially used in pattern designing and cutting stages]. These include primarily bags and luggage, apparel, footwear, worker uniforms, and accessory upcycle products. Based on findings from the systematic review, it recommends a conceptual framework that emphasises the impact of end-of-life PVC flex banners and offers ways for reuse that avoid piling in landfills, incineration, and burying these wastes under the soil, reducing the impact on the environment.
