Grey energy

This article lacks fundamental information about the grey energy content of the pellets (the energy needed to manufacture the pellets). Unfortunatelly, I don't have the info so please help out. --TomTompa 14:04, 22 October 2006 (UTC)[reply]

MBTU/ton

While MWh does mean mega(million)-watthours, MBTU is sometimes read as thousand-BTU. To refer to million-BTU, the abbreviation MMBTU is used to avoid confusion. See British_thermal_unit.

Re the suggested nerger: It may be better to combine the wood pellets with data on wood chips as fuel, and keep a separate page for equipment burning wood pellets/chips. In Europe, particularly Sweden, heater manufacturers supply equipment for burning either pellets (made from compressed sawdust) or wood chips. Wood pellets are useful for making use of what might otherwise be waste from wood products manufacture, and are usually dry, so they burn well. As noted above, wood pellets carry a significant energy cost if wood is ground to powder and dried specifically for pellet manufacture E.g. One manufacturer indicates up to 20% of sawdust is burned to dry the remaining sawdust. Wood chips are therefore a very practical option which avoids the unnecessary steps of grinding the wood and then compacting or extruding to form pellets. —Preceding unsigned comment added by 141.243.60.11 (talk) 06:12, 29 October 2007 (UTC)[reply]

Bias in Environmental Impact

This article does not present a neutral discussion of the environmental impact of burning wood pellets. The author's viewpoint clearly favors their burning and dismisses the legitimate concerns of the side who believes there are environmental concerns. That section should be revised to present a neutral stance on the issue. Barring any comments, my edit would be to remove the "justification" about the carbon cycle and simply include the links to the outside articles on this topic.

Written like an advertisement.

Wow, reading this article I am left to believe that wood pellets are the most perfectest pieces of technological innovation ever. Really? People can't even write articles about unimportant things like hairbrushes or scented candles without listing unperfect characteristics and yet wood pellets have no problems? Whatsoever? Except maybe C02 emissions? Yeah I think article was written by someone with a stake in wood-pelletism. -I agree. Disadvantages are pellets are more expensive per BTU than other fuels in some markets, the initial cost of the burner is high, and the burner may malfunction if you attempt to burn wood chips, coal dust, shredded paper and/or sawdust in it.

Wood pellets and global warming.

I have noted that certain editors have taken exception to the fact that pellets are produced from sawdust, and that combustion of sawdust, releasing carbon dioxide with a GWP₁₀₀ of 1, is less contributive to global warming than allowing sawdust to decay, producing methane, with a GWP₁₀₀ of 25.

If these editors can prove that combustion of sawdust (in pellet form) is more contributive to global warming than sawdust decay, surely they have evidence to back their claims. And surely they have evidence to back their claims that the carbon neutrality of wood pellets harvested from sustainablely managed forests is carbon positive, or the carbon balance of properly controlled biomass combustion using sustainable biomass waste sources is somehow under dispute. Who's disputing it? A coal trafficker? An oil dealer? Katana0182 (talk) 03:24, 30 April 2009 (UTC)[reply]

Wood pellets and global warming.

I don't think editors have argued that combustion of sawdust contributes more to global warming than 100% biological decay of sawdust. Instead, some (like I) have simply taken away claims that burning wood is net carbon negatives - I would like to see the burden of proof on the claims made in the article, not on the assumed ideas of people taking away unsourced claims.

This claim about sawdust has a variety of issues. First, is all sawdust left to decay, or is it used in other applications in which its carbon is not released to the atmosphere? Second, over what time horizon does it decay? Obviously carbon released to the atmosphere in 30 years is better than carbon released today. Finally, does it decay completely? Is 100% of its carbon released to the atmosphere? Of course not. But because no one is writing scathing critiques of sawdust combustion, just trying to take away totally inaccurate claims that burning sawdust is carbon negative, the burden of proof is on those who claim it is. I am disputing the claims about wood pellet burning, and I work at an environmental conservation nonprofit, not a coal company.
