“…Biomass materials are the products of thermal decomposition of various waste biomass (agricultural, forestry, farming waste, etc.). [188] Recently, there is an increasing interest in the development of biomass anodes due to their abundant and renewable resources, inherent porous structure, low cost, and environmental friendliness. [189] Chen et al first proposed to use carbonized biomass material as anode for MFCs.…”

“…[6][7][8] The application of biochar obtained from biomass and organic waste for energy purposes is respond for many global problems as the constantly growing world energy demand, declining of fossil fuel sources, climate changes and rising concentration of dicey waste. [9,10] The ecofriendly nature of biochars reduces the emission of greenhouses gases, and the renewable precursors allow to manage waste and solve the problem of running out of energy resources. [11,12] The energy usefulness of materials is defined by the higher heating value (HHV), also known as gross calorific value (GCV).…”

The nettle, sage, mint and lemon balm herbs were used for biochars preparation. The physicochemical parameters of obtained materials were related to the lignocellulose composition of the precursors. It has been proved that the content of mineral substance has a significant influence on development of surface area, whereas the amount of hemicellulose affects the content of surface functional groups. It has been also shown that the obtained biochars are characterized by great energy parameters. The higher heating values (HHV) of the carbonaceous materials are comparable to the typical energy sources. The greatest HHV value (20.36 MJ/kg) was characteristic for the biochar obtained by pyrolysis of the lemon balm. In addition, the biochars were used for ionic polymers adsorption from one‐ and two‐components solutions. Despite the adsorbed amounts of macromolecules are not great is has been proved that polyethylenimine and polyacrylic acid have positive influence on their mutual adsorption.

“…Improper management of the wastes can result in air pollution, eutrophication from their leachate entering water bodies, and the emission of greenhouse gases (GHGs) such as CH 4 , N 2 O, and CO 2 during decomposition, thereby exacerbating global environmental issues. 1,2 Composting, an environmentally friendly and widely used technique, offers a cost-effective solution to waste reduction and produces a valuable product for agricultural applications and thereby contributing to food security. 3,4 However, composting has its limitations, including the release of GHGs and the loss of nitrogen as ammonia, which can counteract the environmental benefits of composting as a waste management strategy.…”

Composting is an effective waste management technique that not only reduces potentially harmful wastes but also generates valuable products for agricultural applications. This study aimed at producing useful agricultural materials from wastes by investigating the influence of natural and Mg-modified zeolite additives on the composting of chicken manure and sawdust as well as the impact of produced compost on the growth and yield of Hordeum vulgare (barley). Three different levels of natural zeolite and Mgmodified zeolite (0, 10%, and 15%) were co-composted with a mixture of chicken manure, sawdust, and dried leaves to produce five different composts (C, CNZ10, CNZ15, CMZ10, CMZ15). These composts, including 100% compost (C) as a control, were then added to sandy soil at a ratio of 1:3 (compost/soil). Our results revealed that the addition of zeolites enhanced the composting process, especially the 15% Mg-modified zeolite composts (CMZ15), which exhibited a lower electrical conductivity and greater NH 4 + and P retention compared to the other modified and unmodified composts. The NH 4 + and P retention increased by 30% and over 52%, respectively, when the Mg content was increased from 10% to 15% in the modified zeolite. Furthermore, soil amending with CMZ10 and CMZ15 (SCMZ10 and SCMZ15) and used in pot experiments under greenhouse conditions resulted in higher shoot biomass of barley plants, measuring 7.67 and 7.24 g, respectively, compared to SCNZ10, SCNZ15, and SC (6.19, 6.38, and 5.99 g shoot biomass, respectively). This research demonstrates that co-composting chicken manure and sawdust with zeolite, particularly Mg-modified zeolite, improves compost quality and consequently the yield of agricultural products.
