“…Pellets made from shredded wood-based furniture boards laminated with white film were used as the base biofuel. Urea-formaldehyde and melamine-urea resins used to glue the layers of furniture boards together, as well as polyurethane adhesives and melamine-urea-phenol-formaldehyde resins, constitute a potentially good source of NO x and HCN emissions during combustion [ 39 ]. Furniture board waste was collected from a kitchen furniture manufacturing company.…”

A comparative study was carried out of emissions from the catalytic combustion of pellets made from furniture board waste and pellets made from wood mixed with Fe2O3. The mass content of the Fe2O3 catalyst in the fuel was varied from 0% to 5%, 10%, and 15% in relation to the total dry mass weight of the pellets. The average flame temperature in the boiler was between 730 and 800 °C. The effect of the catalyst concentration in the fuel was analysed with respect to the contents of O2, CO2, CO, H2, and NOx in the flue gas and the combustion quality of the pellets in the heating boiler. Changes in the CO2 content and the proportion of unburned combustible components in the combustion residue were assessed. It was established that an increase in the Fe2O3 content of the prepared fuels had a positive effect on reducing NOx, CO, and H2 emissions. However, the proportion of iron oxide in the tested fuel pellets did not significantly influence changes in their combustion quality. A strong effect of the addition of Fe2O3 on the reduction of the average NOx content in the flue gas occurred with the combustion of furniture board fuel, from 51.4 ppm at 0% Fe2O3 to 7.7 ppm for an additive content of 15%. Based on the analysis of the residue in the boiler ash pan, the amount of unburned combustibles relative to their input amounts was found to be 0.09–0.22% for wood pellets and 0.50–0.31% for furniture board waste pellets.

“…Furthermore, formaldehyde is emitted by furniture, insulating materials, and plywood [6][7][8]. Moreover, acetone is emitted from synthetic resins and adhesives, and combustion gases (carbon monoxide and oxides of nitrogen and sulfur) are emitted from stoves and gas ranges [9,10]. Radon emitted from latex matrices and building materials [11] along with volatile organic compounds from cigarette smoke and fine particulate matter are also prevalent indoor contaminants [12][13][14].…”

The mechanical ventilation systems used in houses are designed to reduce carbon dioxide emissions while minimizing the energy loss resulting from ventilation. However, the increase in indoor fine particulate (PM2.5) concentration because of external PM2.5 influx through the ventilation system poses a problem. Here, we analyzed the changes in indoor PM2.5 concentration, distinguishing between cases of high and low outdoor PM2.5 concentrations and considering the efficiency of the filters used in residential mechanical ventilation systems. When using filters with the minimum efficiency reporting value (MERV) of 10 in the ventilation system, the outdoor PM2.5 concentration was 5 μg/m³; compared to the initial concentration, the indoor PM2.5 concentration after 60 min decreased to 73%. When the outdoor PM2.5 concentration was 30–40 μg/m³, the indoor PM2.5 concentration reached 91%. However, when MERV 13 filters were used, the indoor PM2.5 concentration consistently dropped to 73–76%, regardless of the outdoor PM2.5 concentration. Furthermore, by comparing the established equation with the mass balance model, the error was confirmed to be within 5%, indicating a good fit. This allows for the prediction of indoor PM2.5 under various conditions when using mechanical ventilation systems, enabling the formulation of strategies for maintaining indoor PM2.5, as recommended by the World Health Organization.

“…Recently, due to dynamic increase in fuel and energy prices [Inacio et al 2023, Ślusarczyk et al 2023, Wielgosiński et al 2017, Wood et al 2022, there is the risk of deteriorating air quality in inhabited zones -cities, suburbs and villages. Combustion of low-quality fuels in uncontrolled conditions (households) is the source of harmful gases (carbon monoxide and dioxide, sulphur dioxide, nitrogen oxides) and dust, containing polycyclic aromatic hydrocarbons and derivatives, dioxin-like compounds and heavy metals [Grochowalski, Konieczyński 2008, Rybiński et al 2021, Szwed et al 2023. It has been proven that exposure to polluted air induces various diseases and shortens lifespan [Pope, Dockery 2006].…”

Snow cover is a valuable source of information about air quality. It enables detection of dust and other air pollutants which have been accumulated throughout the period since the snow cover was formed. Research conducted in Kielce confirms multidirectional human pressure from local and regional emission sources. Combustion of fuels resulted in lower pH and increased EC, SO4 and NO3 concentrations in the southern and northern parts of the city. Elevated concentrations of Cl and Na indicate the effect of transportation and winter road maintenance. Apart from local emitters, air quality in Kielce is affected by the regional sources, including the nearby center of the lime and cement industries. Climate change is reflected in the number of days with snow and thickness of snow cover, declining since the 1990s.
