FutureMetrics has published several papers regarding the efficacy of the Manomet Study . Hence the combustion of wood does not contribute to the net increase in atmospheric levels of CO2 (a greenhouse gas) as does the combustion of fossil fuels. Will/should it ever be outlawed to curb climate change? More and more communities and air control districts are placing restrictions on respirable-sized particles (PM2.5 or particulate matter smaller than 2.5 microns). — Russ Myers, St. Paul. On the other hand, if we only use as much wood as can grow again, it is carbon dioxide neutral because it binds as much carbon dioxide during growing as is emits during burning. There is a difference of many years, and even decades, between the immediate emissions from burning residues, and the slow evolution of carbon from natural decomposition. Not because it releases CO2, as the net release of CO2 is zero, the trees absorbed it from the atmosphere when they grew. The NOx (if kept below 1300 celsius) and SOx emissions from burning wood are much lower than those of the fossil fuels coal and petroleum products, and comparable to those of natural gas. In contrast, burning pumps the carbon stored in this wood into the atmosphere instantaneously. By William Strauss and Laurenz Schmidt. Feb. 24, 2012 - There has been a lot of debate recently regarding if burning wood releases more or less CO2 emissions when compared to coal, and if it is indeed a "carbon neutral" alternative. In terms of carbon neutrality, the burning of wood often ignores the fossil fuel used in the harvesting, preparation and transporting of wood. Uncontrolled emissions from wood combustion are high in PM2.5. When wood is burned, the combustion reaction produces heat and emissions in the form of water, organic vapors, gases, and particulates. Collection, Preprocessing & Transportation. h�bbd```b``�"��HF/��"�*�$�d��"Y���M`�*��&�j���(����$���m �� ����l&PǠ �30�| ` ��c If fuels are used for electricity generation, carbon dioxide emissions increase with the reciprocal of the power plant efficiency. Other regulated elements and compounds, such as mercury and hydrochloric acid are measurable in the emissions but at levels much below accepted maximums. An open fireplace can draw as much as 300 cubic feet of heated room air up the chimney every minute. Particulate emissions can be controlled to acceptable levels with smoke stack equipment such as scrubbers, bag filters, and electrostatic precipitators. This means 1 Kg of wood is holding about 1.65 to 1.80 Kg of CO 2. Higher temperatures encourage complete combustion and result in cleaner emissions (up to 1300 celsius). Wherever there are bogs, this process happens. The emissions of most concern are carbon monoxide (CO), carbon dioxide (CO2), sulfur oxides (SOx), and nitrogen oxides (NOx). Any opinions, findings, conclusions, or recommendations expressed in this publication are those of the author(s) and do not necessarily reflect the view of the U.S. Department of Agriculture. A wood burning stove is designed to burn at much higher temperatures. But like all open wood burning fireplaces, it is hopelessly inefficient. Heat is produced when C and H combine with oxygen (O) during combustion. e`�j`{�' q7c�L��,g�4���|��!⌼ |�(O The amount of carbon dioxide released from coal and wood depends on the type of coal or wood consumed and the moisture contents of both. Burning the wood reverses this … 2015-41595-24254 from the USDA National Institute of Food and Agriculture. It is reported that 1 Kg of wood contain about 450 to 500 gm of Carbon. This means gases present in the smoke are fully burned and not released back into the atmosphere. %PDF-1.5 %���� E.g. How much CO2 does burning wood for home heating produce? This work is supported by New Technologies for Agriculture Extension grant no. Is heating with wood carbon neutral? Burning wood pellets releases as much or even more carbon dioxide per unit of energy as burning coal, so in order for burning pellets to be carbon-neutral the carbon emitted into the atmosphere has to be recaptured in regenerated forests, Abt says. No. 1, FutureMetrics, January, 2012 . 101 0 obj <> endobj Coal-fired power stations emit on average 1,018 kilograms of carbon dioxide per megawatt hour of electricity. Burning wood is not CO2 free; it releases carbon, stored over the previous decades, in one quick burst.
