“…In last time, the increasingly used solution to the problem of degradation of polyethylene is its combination with natural polymers, such as starch, cellulose or gelatine [9,21]. The solution is based on the statement that the combination of a synthetic polymer (resistant to decomposition) with a natural polymer (prone to biodegradation) in one product will give a material whose chemical structure will partially degrade under the influence of biological factors, while its internal structure will be permanently damaged [29].…”

“…Problems related to environmental protection, relatively expensive methods of recycling synthetic polymer materials, as well as sustainable development aspects have changed the image of multidirectional functionality of polymer materials in recent years. Therefore, at present, intensive scientific studies are being carried out worldwide in many research and development facilities, aimed at finding technologies for the production of environmentally-friendly polymer materials, while maintaining their current functions [5,11,14,21,22].…”

“…According to these authors, the addition of these substances protects polyethylene against oxidation already at the production stage. Pająk et al [8] and Szumigaj-Tarnowska [21] reported that the resistance of polyethylene to degradation is higher compared to other thermoplastics and it is increased even more by the absence of heteroatoms and double bonds in the chain.…”

“…Another form of polyethylene structure modification is the addition of mineral compounds. Such research was carried out by Szumigaj-Tarnowska et al [21]. These authors evaluated changes in the physical properties of polyethylene films modified with mineral compounds (dolomite, calcite) after 12-month degradation of these materials in soil incubated in two temperature ranges (30 °C and 45 °C).…”

“…These authors evaluated changes in the physical properties of polyethylene films modified with mineral compounds (dolomite, calcite) after 12-month degradation of these materials in soil incubated in two temperature ranges (30 °C and 45 °C). SEM images obtained by Szumigaj-Tarnowska et al [21] showed that the incubation of polymer materials enriched with mineral compounds at none of the temperatures caused changes in their surface structure. However, the incubation temperature increase to 45 °C intensified the microbiological processes and increased the number of microorganisms forming the biofilm on the film surfaces.…”

The progressing degradation of the natural environment taking place over the last few decades and resulting from the systematically growing production of synthetic polymer materials led to the search for technological innovations aimed at producing environmentally friendly materials. Moreover, the increasing importance of sustainability promotes the development of bio-based and biodegradable polymers, sometimes misleadingly referred to as "bioplastics". Inability to degrade synthetic polymer materials and the problem of their persistence in the environment even for hundreds of years have caused the production of polymer materials with the addition of components that may accelerate their degradation more and more important in recent years. Additionally, the growing interest in environmental issues makes the requirements for new materials that will not significantly burden the environment higher. In Poland 29.1% and 26.8% of post-consumer polymer materials, respectively, were recovered and recycled, which means that up to 44.1% of post-consumer polymer materials were sent to municipal landfills. In 2017, for the first time in Poland, more plastics were recovered (55.9%) than stored (44.1%). However, by 2020, the level of energy recovery and recycling of post-consumer polymer materials in Poland should cover a total of 84.5%. When looking at the average values for Europe (recycling 31.1%, recovery 41.6%, storage 27.3%), it should be noted that Poland has much to catch up in this area and decisive actions should be taken to actually solve this problem. For this reason, it is extremely important to know the mechanisms responsible for the degradation of polymer materials and understand the interaction between these materials and abiotic and biotic factors that cause structural changes in polymers. Recent studies show that knowledge of the conditions determining the decomposition of polyethylene polymer materials and their impact on the natural environment is still insufficient. The literature reports reveal many contradictory theories, especially those that relate to the degradation of polymer materials in the soil environment. This study constitutes a comprehensive review of researches on (bio)degradation of polymer materials over the last decades, various methods of polymer structure modification to increase the degree of their degradability, as well as methods of recycling post-consumer polymer materials. Because there is a need to assess the performance of polymer innovations in terms of their biodegradability, especially under realistic waste management and environmental conditions, to avoid the unwanted release of plastic degradation products to the environment.
