“…Firewood can be assumed as solar energy storage as the biomass is produced by photosynthesis sequestrating carbon dioxide, which will be returned during burning. If the ash will be used for fertilisation or construction materials [13][14], we can organise closed energy and substance loops. This is only if we will avoid atmospheric pollution.…”

In 2019, 99% of people in the world lived in areas violating WHO’s recommended air quality indicators. By WHO’s estimation, in 2019, air pollution caused 4.2 million premature deaths worldwide. The most harmful are PM2.5 particles, which penetrate the blood through the aerogematic barrier causing cardiovascular and respiratory diseases and cancer. PM10 can pass deeply into the lungs, but they are not so harmful. People always believed that rural air is healthy. Research at the University of Minnesota showed that 18 000 Americans die every year due to air pollution by agriculture, primarily, ammonia (NH3) from the decomposition of fertilizers and livestock waste (12.4 thousand deaths), and PM2.5 particles (4.8 thousand deaths). In polluted areas, plants have more aggressive allergenic pollen. Agricultural waste management and optimization of landscapes are effective ways of solving the problem. In this work, solutions are proposed to improve the air safety of agrocenoses. Minimization of contact of waste with air and its utilisation as soon as possible allows for avoiding decomposition. Converting to gasification boilers/ovens avoids releasing PM2.5 by heating. In addition, plants capable of purifying the air from relevant pollutants should be introduced in agrocenoses. The places for planting are forest protection strips, free places near roads, residential and administrative buildings, etc. In particular, the use of hedges with such plants can provide a local oasis of clean air around houses. In the case of dense land use and lack of free space, it is possible to introduce “green structures” on buildings. An assortment of plants for different regions of Ukraine is offered.

“…In recent years, the literature contains a number of reports on the use of various wastes, including those difficult to manage, for the production of cement mortars and concretes commonly used in construction. For this purpose, waste was used such as ceramics (Ulewicz and Halbiniak, 2016;Kumar et al, 2021), glass (Pietrzak and Ulewicz, 2017;Dong et al, 2021), polymer materials (Pietrzak and Ulewicz, 2018;Pietrzak, 2018;Ulewicz and Pietrzak, 2021) fly ash from biomass combustion (Jura, 2020;Popławski, 2020;Jura and Ulewicz, 2021), ash from sewage sludge incineration (Pietrzak, 2019) or copper industry waste (Helbrych, 2019). Attempts were also made to use asbestos waste in the production of building materials.…”

Asbestos-cement waste from roof coverings and facades are classified as hazardous materials and should be successively removed from buildings. The current management of these wastes is limited to their controlled depositing in landfills, which does not ultimately solve the problem of their impact on the environment in the future. The article presents the current state of disposal of asbestos in Poland, with particular emphasis on the Silesian Voivodeship. The literature reports on the methods of neutralizing this type of waste and the possibility of their recycling were analyzed. It was found that the most popular way of recycling asbestos waste is thermal treatment, and the least effective - chemical treatment. Unfortunately, legal barriers prevent the spread of these solutions in the country in practice, despite the fact that safe methods of recycling asbestos-cement products are known.

“…Other directions of research are necessary, aiming to develop effective technologies for using the ever-growing amount of fly ash from fluidized beds. Attempts have been made to use waste fly ash for the synthesis of zeolites [10][11][12][13], the production of plastics [14,15], geopolymers [16,17], as well as construction materials [18][19][20][21][22][23][24][25][26][27][28][29]. The search for new solutions is particularly important as it is estimated that the global biomass electricity market will grow at a compound annual growth rate (CAGR) of 5.73% in 2023-2032 [30] and, consequently, the amount of waste ash will increase.…”

The article presents an analysis of the possibility of using the waste of polyamide 6 modified with fly ash (in the amount of 5, 10 and 15%) from the burning of wood–palm kernel shells biomass as an addition to cement mortar. Fly ash from the burning of biomass in a circulating fluidized bed boiler (which currently has no practical use) was first used to produce polyamide 6, and then post-production polymer waste (added at 20, 40 and 60%) was used to produce ecological mortar. The use of this type of waste is both economically profitable and desirable due to the need to implement waste material management processes in a closed circuit. The addition of polyamide 6 waste containing 5% fly ash in amounts of 20 and 40% and waste containing 10% ash in 20% to cement mortars improves their mechanical properties. The compressive strength of cement mortars (after 28 days of maturation) containing 20 and 40% of polyamide waste containing 5% fly ash increases by 6.6 and 4.6%, respectively, and the flexural strength by 4.9 and 3.4% compared to the control mortars. However, the compressive strength of mortars with the addition of 20% polyamide waste containing 10% fly ash increases by 4.2% and the flexural strength by 3.7%. Cement mortars modified with waste are characterized by slightly lower water absorption and mechanical strength after the freezing–thawing process (frost resistance) compared to control mortars and do not have an adverse effect on the environment in terms of leaching metal ions.
