A Review Of Biochar Properties And Their Utilization In Crop Agriculture And Livestock Production, Kajetan Kalus, Jacek A. Koziel, Sebastian Opalinski Aug 2019

A Review Of Biochar Properties And Their Utilization In Crop Agriculture And Livestock Production, Kajetan Kalus, Jacek A. Koziel, Sebastian Opalinski

Agricultural and Biosystems Engineering Publications

When it comes to the use of biochar in agriculture, the majority of research conducted in the last decade has focused on its application as a soil amendment and for soil remediation. This treatment improves soil quality, increases crops yields, and sequestrates atmospheric carbon to the soil. Another widely studied aspect connecting biochar with agriculture is the composting processes of various agricultural waste with the addition of biochar. Obtaining the material via the pyrolysis of agricultural waste, including animal manure, has also been investigated. However, given the remarkable properties of biochar, its application potential could be utilized in other areas ...


Proof-Of-Concept Of Spent Mushrooms Compost Torrefaction—Studying The Process Kinetics And The Influence Of Temperature And Duration On The Calorific Value Of The Produced Biocoal, Ewa Syguła, Jacek A. Koziel, Andrzej Białowiec Aug 2019

Proof-Of-Concept Of Spent Mushrooms Compost Torrefaction—Studying The Process Kinetics And The Influence Of Temperature And Duration On The Calorific Value Of The Produced Biocoal, Ewa Syguła, Jacek A. Koziel, Andrzej Białowiec

Agricultural and Biosystems Engineering Publications

Poland, being the 3rd largest and growing producer of mushrooms in the world, generates almost 25% of the total European production. The generation rate of waste mushroom spent compost (MSC) amounts to 5 kg per 1 kg of mushrooms produced. We proposed the MSC treatment via torrefaction for the production of solid fuel—biocoal. In this research, we examined the MSC torrefaction kinetics using thermogravimetric analyses (TGA) and we tested the influence of torrefaction temperature within the range from 200 to 300 °C and treatment time lasting from 20 to 60 min on the resulting biocoal’s (fuel) properties. The ...

Proof-Of-The-Concept Of Spent Mushrooms Compost Torrefaction - Preliminary Studies Of Process Kinetics And The Influence Of Temperature And Duration On Calorific Value Of The Biochar, Ewa Syguła, Jacek A. Koziel, Andrzej Białowiec

Agricultural and Biosystems Engineering Publications

Poland is the 3rd producer of mushrooms in the world. Mushroom production in Poland accounts for nearly 25% of the total production in the EU, and it is still growing. One type of waste generated during mushroom production is mushroom spent compost (MSC), with a 5:1 (MSC: mushrooms) production rate. We investigated valorizing the MSC to produce fuel via torrefaction (‘roasting’, a.k.a. low-temperature pyrolysis). Specifically, we developed models for the MSC torrefaction kinetics using thermogravimetric analyses (TGA) and the effects of torrefaction temperature (200~300 °C) and process duration time (20~60 min) on the resulting biochar ...


Waste To Carbon: Preliminary Research On Mushroom Spent Compost Torrefaction, Ewa Syguła, Jacek A. Koziel, Andrzej Białowiec Jun 2019

Waste To Carbon: Preliminary Research On Mushroom Spent Compost Torrefaction, Ewa Syguła, Jacek A. Koziel, Andrzej Białowiec

Agricultural and Biosystems Engineering Publications

Mushroom production in Poland is an important and dynamically developing element of diverse agriculture. Mushroom spent compost (MSC) is major waste generated during production, i.e., MSC: mushrooms is ~5:1. To date, the main use of MSC is soil application as organic fertilizer. To date, several methods of MSC treatment have been researched and developed including production of compost, bioethanol, biogas, enzyme lactase, xylo-saccharides, and hydrogen. Torrefaction may be considered a novel approach for biomass valorization. Thus, we are pioneering the potential use of MSC valorization via torrefaction. We explored valorizing the waste biomass of MSC via thermal treatment ...


The Proof-Of-The-Concept Of Application Of Pelletization For Mitigation Of Volatile Organic Compounds Emissions From Carbonized Refuse-Derived Fuel, Andrzej Białowiec, Monika Micuda, Antoni Szumny, Jacek Łyczko, Jacek A. Koziel May 2019

The Proof-Of-The-Concept Of Application Of Pelletization For Mitigation Of Volatile Organic Compounds Emissions From Carbonized Refuse-Derived Fuel, Andrzej Białowiec, Monika Micuda, Antoni Szumny, Jacek Łyczko, Jacek A. Koziel

Agricultural and Biosystems Engineering Publications

Waste can be effectively reused through the production of carbonized refuse-derived fuel (CRDF) that enables further energy recovery. Developing cleaner production of CRDF requires consideration of practical issues of storage and handling. Thus, it needs to be ensured that CRDF does not pose an excessive risk to humans and the ecosystem. Very few studies indicate a wide variety of volatile organic compounds (VOCs) are present in CRDF, some of which are toxic. During handling, storage, transportation, and use of VOC-rich CRDF, workers and end-users could be exposed to emissions that could pose a health and safety hazard. Our recent study ...


Fuel Properties Of Torrefied Biomass From Pruning Of Oxytree, Kacper Świechowski, Marek Liszewski, Przemysław Bąbelewski, Jacek A. Koziel, Andrzej Białowiec Apr 2019

Fuel Properties Of Torrefied Biomass From Pruning Of Oxytree, Kacper Świechowski, Marek Liszewski, Przemysław Bąbelewski, Jacek A. Koziel, Andrzej Białowiec

Agricultural and Biosystems Engineering Publications

The very fast growing Oxytree (PaulowniaClonin Vitro 112) is marketed as a promising new energy crop. The tree has characteristically large leaves, thrives in warmer climates, and requires initial pruning for enhanced biomass production in later years. We explored valorizing the waste biomass of initial (first year) pruning via thermal treatment. Specifically, we used torrefaction (‘roasting’) to produce biochar with improved fuel properties. Here for the first time, we examined and summarized the fuel properties data of raw biomass of Oxytree pruning and biochars generated via torrefaction. The effects of torrefaction temperature (200~300 °C), process time (20~60 min ...

The Effect Of Biochar Addition On The Biogas Production Kinetics From The Anaerobic Digestion Of Brewers’ Spent Grain, Marta Dudek, Kacper Świechowski, Piotr Manczarski, Jacek A. Koziel, Andrzej Białowiec

Agricultural and Biosystems Engineering Publications

Biochar (BC) addition is a novel and promising method for biogas yield increase. Brewer’s spent grain (BSG) is an abundant organic waste with a large potential for biogas production. In this research, for the first time, we test the feasibility of increasing biogas yield and rate from BSG digestion by adding BC, which was produced from BSG via torrefaction (low-temperature pyrolysis). Furthermore, we explore the digestion of BSG with the presence BCs produced from BSG via torrefaction (low-temperature pyrolysis). The proposed approach creates two alternative waste-to-energy and waste-to-carbon type utilization pathways for BSG: (1) digestion of BSG waste to ...
