“…Soil conditions can be successfully improved by the sewage sludge application. The literature review confirmed the positive impact of sewage sludge on the growth of plants, the reclamation of degraded lands and the improvement of other properties of soil [11][12][13][14][15][16][17][18] (Table 3).…”

Due to inappropriate agricultural treatments, soils often turn into wastelands. After years, the return to cultivation is very difficult or even impossible. It is a serious problem for agriculture, also in Poland. In order to improve soil quality and to restore its value in use, different fertilizers are commonly used. As an alternative for artificial fertilizers, sewage sludge and biomass ashes might be applied. High cost of sewage sludge conditioning with the use of polyelectrolytes has resulted in the development of research dedicated to finding new and inexpensive conditioners. The article discusses the possibility of sludge conditioning by means of wood biomass ash. In the paper, the findings of sewage sludge dewatering with the use of wood ash on a laboratory and on a technical scale are presented. The analysis of results has shown that the addition of wood biomass ash improved sludge dewatering by 10-23% in a laboratory scale and by 15-27% on a technical scale. The application of wood ash also reduced the total bacteria number by 83-89% in a laboratory scale and by 40-53% on a technical scale. Additionally, the obtained mixture of sewage sludge and wood biomass ash might be applied in agricultural practices, especially in fertilizing perennial plants plantations. Thanks to that it is possible to obtain inexpensive and valuable natural fertilizer while reducing costs of sludge dewatering. Keywords Sewage sludge • Wood biomass ashes • Dewatering • Conditioning • Higienization • Fertilizer Additionally, the final product of sludge dewatering, namely the mixture of sewage sludge and wood ash, can be used as a natural fertilizer improving the plant growth. The sewage sludge conditioning by means of wood biomass ashes and the possibility of the application of mixture is a new solution in sewage sludge management.

“…Currently, energy obtained from biomass constitutes approximately 8-15% of final energy production. It is estimated that such amount will increase to 33-50% by 2050 [16]. For this reason, new methods of utilization in compliance with economical, legal and environmental requirement are required.…”

“…It is widely accepted because biomass energy is a renewable power source that does not release net CO 2 during the combustion process and complies with EU's (2009) directive on renewable energy to mitigate climate change (Shi et al 2016). In European countries, the majority of wood and wood wastes are used for energy production in large plants for district heat and power production (Bartoszewicz-Burczy 2012; Olsson et al 2017).…”

“…According to Kajda-Szcześniak (2014), ash can be used for land restoration, for sealing the bottom of a landfill or for construction (building roads, car park surfaces, embankments for transportation, production of cement, concrete, blocks and bricks). Many studies indicate that wood ash is characterised by high concentration of macroelements (Ca, Mg, K, P) and microelements (Cu, Zn, Mn, Fe, Ni) (Górecka et Shi et al 2016). Due to the composition and alkaline properties of wood ash, it can be used as an alternative to mineral fertilisers containing calcium, potassium and phosphorus.…”

In the present work, we aimed to study the effect of quantitative changes of micronutrients (Cu, Zn, Mn) in soil and plants caused by wood ash applied into the soil in increasing doses. A pot experiment with medium textured soil, white mustard as a test plant and six amendment treatments (doses of wood ash: 0, 1, 5, 10, 20, 30 Mg·ha -1 ) was performed. Total contents of Cu, Zn and Mn were determined in soil and plant samples. Single (DTPA and HCl) and sequential (BCR) extractions were used to evaluate the available amounts of metals and their distribution in fractions. A plant's ability to accumulate metals from soils was estimated using the bioconcentration factor (BCF), which is defined as the ratio of metal concentration in the plants to that in soil. The increasing doses of wood ash increased total and available contents of trace elements, especially Cu and Mn. The distribution of metals among particular fractions depended mainly on their geochemical character. The highest content of Cu was found in the reducible and oxidisable fractions, whereas, the greatest amounts of Zn and Mn were in the exchangeable and reducible fractions, and the lowest in the oxidisable fraction. Despite small wood ash influence on metal distribution in the individual soil fractions, increasing doses of wood ash increased the amounts of Cu, Zn, Mn in easily soluble fractions, which are potentially available to plants. As a result of wood ash increasing doses application, the higher amounts of Cu, Zn and Mn in plant tissues were found. However, only in the case of Zn, the value of BCF indicated on such accumulation in the plants.

Biomass-energy processes are those used to obtain energy by the burning or biochemical converting of any organic matter to be used for fuel. In recent years, some materials used as a source for biomass energy have been obtained from the discards of agricultural activities. These include wood, sawdust, corn, sugarcane and rice husks, among others. The processes for converting biomass into energy are numerous. The most commonly used are combustion, co-firing process and pyrolysis. The residual endproducts obtained from these processes are highly dependent on the process conditions, especially temperature, pressure and atmosphere. Char and ashes are the most commonly obtained materials. The objective of this work is to analyse the feasibility of reusing these discards of biomass-energy processes, as additions in clay mixtures for the production of ceramic materials for civil construction. For this purpose, charcoal and ashes obtained from various biomasses have been characterized by SEM, EDS, DTA-TGA, XRD, etc. These results, and the determination of the theoretical sintering temperatures by the use of ternary diagrams, lead to the establishment of the feasibility of using these discards in current ceramic industry processes. Charcoal and ashes from sunflower husks, brewery waste and pine sawdust are the materials studied.
