The issue of biochar application as a non-conventional fertilizer is of growing interest currently. Biochar is a product of the pyrolysis of organic waste for example and unlike conventional fertilizer, biochar is a long-acting agent. The use of such fertilizer should not only increase the yield of crops, but also the sequestration of carbon in the soil and reduce the impact on climate change. An additional advantage of biochar is its developed surface, which makes it possible to use it as a carrier for beneficial...

This article presents the potential of biochar used in wastewater treatment processes and sludge management in small installations - for the maximum maintained number of users equal to 50. The possibilities of two substances used in sewage management processes, such as char and biochar will be presented. These substances, produced from pyrolysis, are stable carbon-rich compounds which have various beneficial applications like soil conditioning, remediation and wastewater treatment. In particular, biochar originati...

Pyrolysis is considered as an effective and alternative way to treat organic waste and to obtain pyrolysis fuels as well as biochar. The latter may be used for different purposes in industry and agriculture, including use as a long term fertilizer. Biochar, after pyrolysis, is obtained in the form of powder; however from practical point of view it is better to use pelleted or granulated biochar since it significantly enhances biochar?s filed distribution. In our study we compared the efficacy of granulated and pow...

Biochar attracts high scientific and practical interest because of several specific properties such as high sorption potential, fertilizing properties and ability to sequester carbon. In the present study, fertilizing properties of biochar made of chicken manure using different peak temperatures (2h at 300-700 ?C) in the rotating experimental 200L biomass pyrolysis plant were investigated. The following parameters were analyzed: content of biogenic elements (C, N, P, K), porosity and micromorphology, toxicity for ...

Biochar is a product of pyrolysis of biomass such as plant residues, organic wastes or etc. Being highly porous material that slowly releases nutrients, biochar is considered as an effective alternative fertilizer. It is reported that biochar properties are depending on the pyrolysis regime (e.g. pyrolysis peak temperature and duration), however information about quantitative dependences remains poor, especially for biochars made of specific substrates such as chicken manure. In this study, properties of biochars ...

How to use fermentation residues is a burden on many biogas plants. Incorporation into arable land remains the most common approach, although application costs represent approximately the same benefit for fertilization, despite the risk of soil formation and the associated degradation of the soil's ability to retain water. An alternative how to use spent dust is to re-enter into raw material of the biogas plant or a second alternative is to use dust coal as wall surfaces in the interior because of its sorption cap...

Climate change is a global problem and carbon sequestration is one of the possible ways to reduce it. After application of organic matter to the soil, most of the carbon is mineralized and released into the atmosphere where it becomes a part of the greenhouse gas. Biochar is also an organic matter but it contains carbon in a form that is mineralized slowly (hundreds to thousands years). In addition to these complex compounds, it also contains readily available carbon and also aromatic substances which may be toxic...

The aim of this article is assessment biochar bioremediation potential in the benzo[a]pyrene artificially contaminated Haplic Chernozem with various doses of benzo[a]pyrene (200, 400 and 800 ?g/kg) equivalent to 10, 20 and 40 levels of maximal permissible concentrations (MPC) and 1-5% biochar amendment. The main subject of this study is to research the most effective dose of biochar amendment in benzo[a]pyrene contaminated soil in a model experiment with chernozem. The content of benzo[a]pyrene in soil was determi...

High concentrations of ammonium, toxic organic compounds, pathogenic microflora make chicken manure one of the most toxic agricultural wastes. The use of chicken manure in plant growing is only possible after its treatment, e.g. by means of composting or anaerobic digestion. One of alternative ways of chicken manure treatment is its pyrolysis, as a result of which pyrolysis fuel and biochar are produced. The latter can be used as nontraditional organic fertilizer. However, the properties of biochar produced from c...

According to FAO, the Food and Agriculture Organization of the United Nations, global annual charcoal production amounts to 52 million metric tons. Around half of the population in South America depends on forest-sourced resources (firewood, charcoal) to cover their basic energy needs, and in some countries large-scale industrial charcoal usage is further common, e.g. in Brazil in the production of pig iron for steel. To limit adverse impacts on forest health, sustainability of charcoal production merits high atte...

In the recent years, growing interest to biochar as a means of improving soil quality is observed. Biochar is a product of pyrolysis of biomass such as plant residues or organic wastes. Biochars made of manures are special because they can solve two environmental problems simultaneously ? waste reduction and soil fertilization, but they are less studied. In our research, we suggest to improve the properties of biochars derived from manures by means of immobilizing beneficial microbes on them. In this study, the ch...
