“…Plants, animals, microorganisms, and agricultural wastes are examples of natural biological sources of biopolymers. Plant sources, such as rice, maize [ 8 ], wheat [ 9 ], sorghum [ 10 ], yams [ 11 ], cassava [ 12 ], potatoes [ 13 ], banana [ 14 ], tapioca [ 15 ], corn [ 16 ], cotton [ 17 ], and barley [ 18 ] biopolymers can be produced chemically from monomeric components, such as oils, sugars, and amino acids. Cattles are the most common animal sources, while corals, sponges, fish, lobster, and shrimp are the most common marine sources.…”

Biopolymers are a leading class of functional material suitable for high-value applications and are of great interest to researchers and professionals across various disciplines. Interdisciplinary research is important to understand the basic and applied aspects of biopolymers to address several complex problems associated with good health and well-being. To reduce the environmental impact and dependence on fossil fuels, a lot of effort has gone into replacing synthetic polymers with biodegradable materials, especially those derived from natural resources. In this regard, many types of natural or biopolymers have been developed to meet the needs of ever-expanding applications. These biopolymers are currently used in food applications and are expanding their use in the pharmaceutical and medical industries due to their unique properties. This review focuses on the various uses of biopolymers in the food and medical industry and provides a future outlook for the biopolymer industry.

“…The wood lignins most studied come from pine, spruce, birch and aspen. The structural features of lignins extracted from agricultural plants, including cereals, have been investigated much less frequently [87]. Lignin is isolated from black liquor, which is a by-product in the wood pulping process.…”

“…Numerous studies have indicated the possibility of using lignins as enterosorbents capable of binding, among others, radionuclides and estrogens [82,87,100]. The mechanism of ion adsorption on the lignin surface is based on the reaction of functional groups that have the ability to bind metal ions by donating an electron pair and thus form complexes or new chemical bonds with the adsorbate [101][102][103].…”

The overproduction of pollutants resulting from the development of industry causes the deposition of large amounts of toxic and carcinogenic substances, including heavy metals, in the aquatic ecosystem and other ecosystems. This is a civilisation problem of the present times, posing a serious threat to the natural environment, including humans. For this reason, it has recently become extremely important to develop effective methods to minimise the concentration of heavy metal ions in the aquatic systems and thus reduce their negative impact on the environment. One such technique is adsorption, which is believed to be an effective method of removing contaminants such as heavy metal ions from aqueous solutions. Looking at the available literature of the last few years, it can be concluded that adsorbents of natural origin are becoming more and more important. These are agricultural waste, all kinds of biomass, and waste from various industries. The study attempts to present and evaluate the sorption capacity of materials of natural origin, including oat bran, chitosan, alginate, tree bark, coconut fibre, and lignin. The use of such biosorbents is more friendly for the environment compared to their synthetic counterparts and perfectly fits the concept of sustainable development and the circular economy.

During the baling operation, the wheat stalks are subjected to various mechanisms in the baler and the main form is compression. After the wheat stem is forced by a combination of the threshing cylinder, it needs to be formed under the action of straw baler and meet transport requirements. This paper mainly studies the properties of wheat stalks when baling, and proposes the application of the creep after-effect theory during the baling process. The tension-compression tester was used to perform a 50 mm stalk mechanical test, 50 mm stalk static pressure test, 35 mm×40 mm×50 mm stalk module static pressure test and bale static pressure test. The measured elastic modulus of the stem sample was 7.59 MPa, and the elastic modulus of the inner core of the stem was 8.24 MPa. The return curve of the single stalk and the bale is consistent with the initial creep and steady-state creep in the creep after-effect theory. A logarithmic function was used for fitting of the first stage with coefficient of determination R 2 = 0.8364, and a linear function was used for fitting of the second stage with coefficient of determination R 2 = 0.9921. The high water content static pressure test suggests that the load in the loading direction is the coupled load of the working load of the hydraulic cylinder and the internal stress of the bale. When harvesting wheat stalks with high moisture content, the density parameter of the bale can be appropriately increased while the load parameter of the hydraulic cylinder can be considered unchanged or even reduced. The adjustment of density and load can still ensure the forming quality of the bale.
