During coronavirus disease 2019 pandemic, the exponential increase in clinical waste (CW) generation has caused immense burden to CW treatment facilities. Co-incineration of CW in municipal solid waste incinerator (MSWI) is an emergency treatment method. A material flow model was developed to estimate the change in feedstock characteristics and resulting acid gas emission under different CW co-incineration ratios. The ash contents and lower heating values of the feedstocks, as well as HCl concentrations in flue gas showed an upward trend. Subsequently, 72 incineration residue samples were collected from a MSWI performing co-incineration (CW ratio <10 wt%) in Wuhan city, China, followed by 20 incineration residues samples from waste that were not co-incineration. The results showed that the contents of major elements and non-volatile heavy metals in the air pollution control residues increased during co-incineration but were within the reported ranges, whereas those in the bottom ashes revealed no significant changes. The impact of CW co-incineration at a ratio <10 wt% on the distribution of elements in the incineration residues was not significant. However, increase in alkali metals and HCl in flue gas may cause potential boiler corrosion. These results provide valuable insights into pollution control in MSWI during pandemic.

“…The most important task of fl ue gas treatment systems is to remove substances that after being emitted to the environment could have a negative impact on the environment, as well as people and animals (Wielgosiński, Namiecińska & Czerwińska, 2018, Xiao et al, 2018Zhang, Yu, Shao & He, 2019). Table 7 presents a summary of emissions from fi ve Polish waste incineration plants together with the limit values.…”

All municipal waste incineration plants operating in Poland are discussed and their flue gas treatment systems are described in detail in the article. A comparison of performance indicators, i.e. the amount of raw materials consumed particularly in flue gas treatment systems, is presented. The article also summarizes the results of emission measurements for eight incineration plants in the years 2016–2019.

“…HCl can acidify soil and water, and also damage or even kill plants. Moreover, it can damage the skins, mucosa of eyes and noses of human beings and animals [12][13][14]. The standard from Occupational Safety and Health Administration defines the Immediately Dangerous to Life or Health concentrations of HCl are 50 ppm and 5 ppm, respectively [15].…”

Cellulose nano-crystals as a sensitive and selective layer for high performance surface acoustic wave HCl gas sensors

We report that cellulose nano-crystals (CNCs) can be used as a sensitive and selective layer in surface acoustic wave (SAW) sensors for in-situ HCl gas detection. CNCs were prepared through directly hydrolysis of cotton fiber and were spin-coated on quartz SAW resonators to form the sensitive layer. The CNCs have been identified to have abundant hydroxyl groups on their surfaces, which can act as the perfect adsorption sites for H2O, which can further act as the active sites for HCl gas adsorption. The absorption of HCl on the CNCs layer, thus leads to an increase of its mass, causing negative responses of the SAW sensors. Ambient humidity and thickness of CNCs layer are found to have significant influences on the responses of the SAW sensor. With an 80-nm-thick CNCs layer, the sensor shows a response of -2 kHz to 1 ppm HCl at 25 °C and relative humidity of 50% with an excellent selectivity and recovery characteristics.
