A documentary about the burning of wood at an industrial scale for energy, “BURNED: Are Trees the New Coal?” tells the little-known story of the accelerating destruction of our forests for fuel, and probes the policy loopholes, huge subsidies, and blatant greenwashing of the burgeoning biomass power industry.

Largest wood pellet manufacturer in the U.S. is proposing to build the world’s largest wood pellet mill in Lucedale, Mississippi in George County. Some residents are for it, others question environmental impact.
Residents of Lucedale who showed up in force to a public hearing Tuesday already made up their minds about the largest wood pellet mill in the country locating in their town.
They wore stickers announcing their position. And they weren’t swayed by speakers who came mostly from outside the area, arguing that while Enviva might be good for the bottom line, it might not be good for the health of the community.
The company proposes building a $140 million pellet plant in the George County Industrial Park in Lucedale and a $60 million shipping terminal in Pascagoula. The state Legislature appropriated more than $2 million to fix the rail spur between the two.
The pellets will be made mostly from pine trees in and around George County and shipped overseas to supply fuel for power plants in the United Kingdom, Asia and other countries.
Tuesday’s meeting was the last step in the review process before the Mississippi Department of Environmental Quality decides whether to approve the pollution control equipment so the plant can operate within the legal limits of Mississippi. The decision could come as early as the June 11 meeting of the MDEQ review board, which meets the second Tuesday of each month.
Is wood pellet-based electricity less carbon-intensive than coal-based electricity? It depends on perspectives, baselines, feedstocks, and forest management practices

Some studies suggest that the carbon intensity of electricity generated in the United Kingdom by using imported wood pellets from the southern United States is higher than that of coal-based electricity, whereas other studies suggest that the use of wood pellet-based electricity reduces carbon emissions significantly, relative to coal-based electricity. We developed the Forest Bioenergy Carbon Accounting Model (ForBioCAM 1.0) to analyze factors that influence the carbon intensity of wood pellet-based electricity, using a common set of assumptions and the same system boundary. We show that widely differing assessments of the carbon intensity of wood pellet-based electricity depend on the choice of forest management perspectives (landscape or stand), baselines (no harvest, or harvesting for the manufacture of traditional finished wood products), feedstocks (whole trees, pulpwood, or logging residues), forest management practices (change in rotation age), and the duration of the analysis itself. Unlike with a stand perspective, we demonstrate conditions under which a landscape perspective results in carbon savings net of avoided emissions from coal-based electricity. Our results also suggest that the two perspectives of forest management converge in their assessment of the positive carbon effects of various feedstock types used to manufacture wood pellets relative to a no-harvest baseline, and that the use of whole trees for wood pellets results in net carbon savings after a break-even period of about three years relative to a no-harvest scenario. The results of this study can guide future policy deliberations on the use of wood pellets as a renewable energy source worldwide.

In 2016, the wood pellet market in Europe reached a size of 19 million tons per annum (Mtpa), while production capacity stood at 23.5 Mtpa, and consists of two largely independent sectors with only limited interaction. The industrial market is focused on large-scale bioenergy generation, while the premium market is focused on small-scale residential and commercial heat generation.
Besides more growth potential in the industrial market to 2025, the likely expansion of the premium sector post-2020 offers an opportunity for North American producers to soften the impact of predicted demand decline for industrial pellets post-2027.
