    Nikola Bilandžija Neven Voća Josip Leto Vanja Jurišić Mateja Grubor Ana Matin Anja Geršić Tajana Krička https://doi.org/10.21278/TOF.42Si105 ISSN 1333-1124 eISSN 1849-1391 YIELD AND BIOMASS COMPOSITION OF MISCANTHUS X GIGANTEUS IN THE MOUNTAIN AREA OF CROATIA Summary Although biomass of Miscanthus x giganteus shows a significant potential for production of second-generation biofuels, it is currently mostly used as a combustion fuel. The objective of this paper is to investigate: (I) dry matter yield and yield components; (II) biomass composition; and (III) potential divergences of the investigated parameters from the standard for solid fuels CEN/TS 14961:2005, in relation to two harvest seasons and six fertilizer treatments. The investigation has determined that there is a potential for producing significant quantity of biomass from M x giganteus in the investigated agro-ecological conditions of the mountain areas of Croatia. The laboratory analyses indicated the suitability of using biomass in direct combustion. Key words: Energy crop, Miscanthus x giganteus, dry matter yield, combustion properties 1. Introduction According to the objectives of the Energy Strategy for Europe until 2020, Framework for climate and energy policies until 2030 and the UN Climate Change Conference (Paris Climate Agreement - COP 21), the renewable energy sources emerge as one of the most important element of energy self-sufficiency and for mitigating climate changes [1, 2]. Agricultural biomass as a component of renewable energy sources represents a significant source of different raw materials in the “green energy” production system. Perennial grasses represent the biomass crops suitable for sustainable bioenergy production.

  • Coal Ash: SEVEN MYTHS the Utility Industry Wants You to Believe and SEVEN FACTS You Need to Know
    Coal Ash: SEVEN MYTHS the Utility Industry Wants You to Believe and SEVEN FACTS You Need to Know Myth #1: Coal ash is like dirt. Fact: Coal ash is hazardous. According to the U.S. Environmental Protection Agency (EPA), a waste is “hazardous” if it leaches toxic chemicals, like arsenic or selenium, above a certain threshold when tested using the Toxicity Characteristic Leaching Procedure (TCLP). Using the TCLP, coal ash rarely exceeds this threshold. However, the EPA’s Science Advisory Board and the National Academy of Sciences have determined that the TCLP does not accurately predict the toxicity of coal ash.1 When EPA tests coal ash using a new, more accurate leach test, the resulting leachate can exceed by many times these hazardous waste thresholds.2 For example, when tested with EPA’s new, more accurate test, coal ash leached arsenic at up to 18,000 parts per billion (ppb), which is 1,800 times the federal drinking water standard and over 3 times the hazardous waste threshold.3 The new test revealed selenium leached from one coal ash at up to 29,000 ppb, which is 580 times the drinking water standard and 29 times the hazardous waste threshold.4 This is not backyard soil-- unless you live at a Superfund site. Because of the pollutants in coal ash, leachate from ponds, landfills and fill projects can severely damage health and the environment. EPA’s 2010 risk assessment found the cancer risk from drinking water contaminated with arsenic from coal ash disposed in unlined ponds is as high as 1 in 50 adults, which is 2,000 times EPA’s regulatory goal for acceptable cancer risk.5 Dry landfills can also pose dangers to drinking water and aquatic life, according to the EPA.

  • Wood Ashes: to Use Or Not to Use
    Wood Ashes: To Use or Not To Use By Gretchen Spencer, Fairfax Master Gardener Is there a place for wood ashes in the garden or on the lawn? This is a question I’ve asked myself over the years as I carefully scooped the wood ashes out of our well-used wood stove that keeps our family room cozy and warm all winter long. Careful to make sure that the ashes are completely cool, I usually place them in a metal container outdoors for a few days before bagging them up and putting them in the trash, despite the nagging feeling that there by author must be a use for them in the garden. Having tried over the years to commit myself to organic gardening, I decided to fully investigate this photo: question. First, I learned that it’s important to understand the composition of wood ash. Wood ash, especially ash from hardwood trees, contains calcium, potassium (potash), phosphorus, magnesium and other trace elements. During the burning process, nitrogen and sulfur burn off as gas. Wood ash is highest in calcium and acts the same way on soil as lime: it raises the pH of the soil to make it more alkaline. Potassium, or potash, is one of three major nutrients that all plants need. The other two being nitrogen and phosphorus. Potassium is important for the overall strength of the plant and helps plants to resist diseases. Wood ash is also a good source of micronutrients that plants need in trace amounts. So, given the beneficial composition of wood ash, it seems like I should be able to just spread ashes everywhere in my garden and on my lawn.

  • Is Coal Ash and Slag Any Useful Or Unloaded Wastes?
    IS COAL ASH AND SLAG ANY USEFUL OR UNLOADED WASTES? E. Botezatu, C. Grecea, O. Iacob Institute of Public Health, Radiation Protection Department 14, V. Babes Street, 6600 Iasi, Romania INTRODUCTION It is well known that all types of coal, like most materials found in nature, contain trace quantities of the naturally occurring primordial radionuclides (uranium and thorium families and potassium-40). Therefore, the combustion of coal results in partitioning of radionuclides included in the non-combustible mineral matter, between the bottom ash and fly ash, and in the release into the environment of large amounts of coal ash. Emissions from thermal power stations in gaseous and particulate form contain radioisotopes arising from the uranium and thorium series as well as from 40K. They are discharged into the environment causing changes in the natural radiation background and radiation exposures to the population. The continued releases of these materials to environment may result in a buildup in the air, water and soil of the radionuclides, particularly radium-226. There will be an increase of the basic radiation rate in the neighborhood area of these plants and consequently relatively higher exposure of the local population to radiation. Coal burning is, therefore, one of the sources of technologically enhanced exposure to humans from natural radionuclides (1,2,3,4,5,6). Coal based thermal power plants constitute about 35% of quantum of energy supply in Romania. In view of the importance of coal for energy supply in Romania, we were interested in knowing possible uses of the resulting wastes and minimize the following harmful consequences of coal burning.

  • Temperature Effects on the Ash Colour of Forest Litter

Research was carried out to identify the influence of temperature (150, 250, 350, 450, 550ºC) on the ash colour of Acer platanoides L. leaf litter and Pinus sylvestris L. needle litter samples collected from deciduous coniferous mixed forest in Lithuania (54º43‘ N 25º19‘ E) in April 2010. To achieve the objective, a laboratory experiment was conducted to determine ash samples using the Munsell Colour Chart. The analysis of colours has demonstrated that considering all litter samples, an increase in the temperature of litter heating was found to increase ash colour values (r = 0.92; p = 0.01). All the samples (n = 50) of both litter species were divided into categories 2.5Y (5 samples), 7.5YR (10 samples) and 10YR (35 samples). The total black Munsell colour was observed at a temperature of 350ºC for both litter species. Needle ash started turning bright at a temperature of 550ºC while the complete consumption of leaf litter was visible at a temperature of 450ºC. We conclude that the Munsell Colour Chart used for predicting the colour of ash is an informative feature to have the primary classification of ash.

  • AP-42, Vol. I, CH1.1 Bituminous and Subbituminous Coal Combustion
    1.1 Bituminous And Subbituminous Coal Combustion 1.1.1 General Coal is a complex combination of organic matter and inorganic mineral matter formed over eons from successive layers of fallen vegetation. Coals are classified by rank according to their progressive alteration in the natural metamorphosis from lignite to anthracite. Coal rank depends on the volatile matter, fixed carbon, inherent moisture, and oxygen, although no single parameter defines a rank. Typically, coal rank increases as the amount of fixed carbon increases and the amount of volatile matter and moisture decreases. Bituminous coals are by far the largest group and are characterized as having lower fixed carbon and higher volatile matter than anthracite. The key distinguishing characteristics of bituminous coal are its relative volatile matter and sulfur content as well as its slagging and agglomerating characteristics. Subbituminous coals have higher moisture and volatile matter and lower sulfur content than bituminous coals and may be used as an alternative fuel in some boilers originally designed to burn bituminous coals.1 Generally, bituminous coals have heating values of 10,500 to 14,000 British thermal units per pound (Btu/lb) on a wet, mineral-matter-free basis.2 As mined, the heating values of typical U.S. bituminous coals range from 10,720 to 14,730 Btu/lb.3 The heating values of subbituminous coals range from 8,300 to 11,500 Btu/lb on a wet, mineral-matter-free basis2, and from 9,420 to 10,130 Btu/lb on an as-mined basis.3 Formulae and tables for classifying coals are given in Reference 2.

  • Safe Cleanup of Fire Ash and Debris
    Safe Cleanup of Fire Ash and Debris The local fires have resulted in large volumes of fire ash and debris throughout San Diego County. When mandatory evacuations are lifted, residents who return to their effected homes and neighborhood should use caution when they come in contact with these materials. According to the California Department of Health and Human Services, ash deposited by forest fires is relatively nontoxic and similar to ash found in fireplaces, however, any ash‹particularly from ash and debris found inside burned structures‹will contain small amounts of cancer-causing chemicals or carcinogens. It's important to note that ash may be irritating to the skin (especially to those with sensitive skin) and if breathed could irritate the nose and throat causing coughing and even trigger asthmatic attacks in people who have asthma. In an effort to avoid possible health problems the California Environmental Protection Agency has developed a list of recommended steps to follow when cleaning up after a fire: • Do not allow children to play in ash. • Wash ash off children¹s toys before children play with them. • Clean ash off house pets. • Wear gloves, long sleeved shirts and long pants and avoid skin contact. • If you do get ash on your skin, wash it off as soon as possible. • If you have a vegetable garden or fruit trees, wash the fruit or vegetables thoroughly before eating them. • Avoid getting ash in the air as much as possible. Do not use leaf blowers or take other actions that will put ash in the air. • Gentle sweeping of indoor and outdoor hard surfaces followed by wet mopping is the best procedure in most cases.

  • Miscanthus: a Fastgrowing Crop for Biofuels and Chemicals Production
    Review Miscanthus: a fast- growing crop for biofuels and chemicals production Nicolas Brosse, Université de Lorraine, Vandoeuvre-lès-Nancy, France Anthony Dufour, CNRS, Université de Lorraine, Nancy, France Xianzhi Meng, Qining Sun, and Arthur Ragauskas, Georgia Institute of Technology, Atlanta, GA, USA Received February 9, 2012; revised April 17, 2012; accepted April 18, 2012 View online at Wiley Online Library (wileyonlinelibrary.com); DOI: 10.1002/bbb.1353; Biofuels, Bioprod. Bioref. (2012) Abstract: Miscanthus represents a key cand idate energy crop for use in biomass-to-liquid fuel-conversion processes and biorefi neries to produce a range of liquid fuels and chemicals; it has recently attracted considerable attention. Its yield, elemental composition, carbohydrate and lignin content and composition are of high importance to be reviewed for future biofuel production and development. Starting from Miscanthus, various pre-treatment technolo- gies have recently been developed in the literature to break down the lignin structure, disrupt the crystalline structure of cellulose, and enhance its enzyme digestibility. These technologies included chemical, physicochemical, and biological pre-treatments. Due to its signifi cantly lower concentrations of moisture and ash, Miscanthus also repre- sents a key candidate crop for use in biomass-to-liquid conversion processes to produce a range of liquid fuels and chemicals by thermochemical conversion. The goal of this paper is to review the current status of the technology for biofuel production from
