Biomass, a renewable energy source derived from organic matter such as wood, crop waste, or garbage, makes up 4.8 percent of total U.S. energy consumption and about 12 percent of all U.S. renewable energy. Human generated waste is the largest biomass energy source. In the U.S., as of 2018 there are currently 285 biomass plants operating. In the U.K., 42 are operating, 15 are under construction and 27 have been proposed. But just how renewable is biomass energy?
There are several ways to produce energy from waste products, including incineration by burning biomass to generate heat in order to run steam turbines that produce electricity, burning biomass to produce heat in thermal systems (when combined with electricity generation, it’s called “combined heat and power”), turning feedstocks into liquid biofuels, harvesting gas from landfills or anaerobic digesters, and finally my favorite..The Conversion of Biomass in the form of organic (Human) waste products otherwise known as (Garbage) which is lying around in landfills, rivers and eventually make their way into our water supply and ground water or aquifers. This is by far the most abundant and renewable energy source.
Biomass can consist of wood from forests and logging residues, sawdust from lumbermills, construction or organic municipal waste, energy crops (switchgrass), crop residue, and even chicken litter. In the past, the rapid expansion of biomass energy relied largely on wood from forests, however, for this article we’ll focus here on energy produced by the conversion process of biomass from human generated waste in or around municipalities and or dense populations or people in contrast to wood or plant-based fuel sources.
Biomass advocates maintain that thinning out small-diameter or dead trees from overcrowded forests and harvesting the byproducts of forest management such as limbs, treetops, needles, leaves, etc. improves the health of the trees that remain in the forest and helps reduce the incidence of wildfires. Biomass creates jobs and supports local economies by providing new markets for farmers and forest owners. It can also lessen our dependence on fossil fuels, and under certain conditions, can reduce greenhouse gas emissions if done correctly with the right machinery.
Biomass is considered a renewable energy source because its inherent energy originally came from the sun and because it can regrow in a relatively short time. Trees take in carbon dioxide from the atmosphere and convert it into biomass and when they die, it is then released back into the atmosphere. Whether trees are burned or whether they decompose naturally, they release the same amount of carbon dioxide into the atmosphere. The idea is that if trees harvested as biomass are replanted as fast as the wood is burned, new trees take up the carbon produced by the combustion, the carbon cycle theoretically remains in balance, and no extra carbon is added to the atmospheric balance sheet—so biomass is arguably considered “carbon neutral.” Since nothing offsets the CO2 that fossil fuel burning produces, replacing fossil fuels with biomass theoretically results in reduced carbon emissions.
The fact is, the reality is a lot more complicated. In 2017, the U.S. Environmental Protection Agency (EPA) found that “carbon neutrality cannot be assumed for all (BIOMASS) energy plants.” Whether or not biomass is truly carbon neutral depends on the time frame being studied, what type of biomass is used, the combustion technology, which fossil fuel is being replaced (since the combustion of both fossil fuels and biomass produces carbon dioxide), and what forest management techniques are employed in the areas where the biomass is harvested.
Most of the new biomass electricity generating plants being proposed in the U.S. will burn wood. Plants in the Southeast U.S. are churning out wood pellets to meet Europe’s increasing need for wood. Last year, wood pellet exports from the Southeast increased 70 percent; the Southern U.S. is now the largest exporter of wood pellets in the world. Since there isn’t enough logging residue to meet the increased demand for biomass, many fear that more standing trees will be chopped and more forests clear-cut.
In 2010, a group of scientists wrote to Congress explaining that the notion that all biomass results in a 100 percent reduction of carbon emissions is wrong. Biomass can quickly reduce carbon dioxide if fast growing crops are grown on otherwise unproductive land; in this case, the regrowth of the plants offsets the carbon produced by the combustion of the crops. But cutting or clearing forests for energy, either to burn trees or to plant energy crops, releases carbon into the atmosphere that would have been sequestered had the trees remained untouched, and the re-growing and thus recapture of carbon can take decades or even a century. Moreover, carbon is emitted in the combustion process, resulting in a net increase of CO2.
Because it’s the new CLEAN FUEL, The Necessity of Pelletizing Municipal Solid Waste into Refuse-derived Fuel Pellets Solid wastes are any discarded materials. They can be solid, liquid, semi-solid or containerized gaseous material. In the light of a survey conducted by World Watch Institute, the total volume of municipal solid waste (MSW) is about 1.3 billion tons per year in the world (MSW is measured before disposal, so data on it include material that is later diverted for recycling). Moreover, it is predicted that the number will be doubled annually by 2025. The disposal of MSW is a matter of increasing concern for governments all around the world. Previous managements are still adopted by municipalities and governments. Innovative ideas are on the way.
Nevertheless, biomass energy is currently considered renewable, and thus qualifies for tax credits, subsidies and incentives in the U.S. These include the Renewable Electricity Production Tax Credit which pays closed-loop (organic matter planted exclusively to produce electricity) biomass energy producers $.023 per kilowatt-hour and open-loop biomass (any other waste or residue) producers $.012 per kilowatt-hour; and Renewable Energy Certificates wherein every megawatt hour of electricity generated by biomass earns a credit that can be sold, traded or bartered, giving its owner the right to claim to have purchased renewable energy. The Investment Tax Credit will reimburse 30 percent of biomass plant development if construction is begun by the end of this year, and if operation begins by 2024. And biomass is eligible for subsidies from the U.S. Department of Agriculture.
In part due to these incentives and the pressure to reduce coal use, energy companies in the U.S. and Europe are turning to biomass. By 2030, biomass could account for over 60 percent of total final global renewable energy use and eliminate over 80% of accumulative garbage created by municipalities , according to the International Renewable Energy Agency May, 2018
Old biomass plants produce over 38 megawatts of electricity on average, but US Green Energy, LLC. are building theirs in the 50 to 110-megawatt range. According to the Partnership for Policy Integrity, a 50-megawatt plant burns 2,550 lb. of garbage each minute. As an example, the 50-megawatt McNeil plant in Burlington, VT burns 625,000 tons of green wood from trees and residue each year. Additional wood is needed for co-firing in coal plants where wood is burned with coal to meet state renewable energy mandates (resulting in additional carbon emissions), pellet production, and liquid bio-fuels. While admittedly most forests will not actually be clear-cut for biomass energy, the numbers make clear the amount of pressure that will be brought to bear on our forests and this can be replaced by conversion of human organic and non organic waste products. Although the products need to be separated prior to the conversion process, US Green Energy, LLC. has separator refinement equipment available.
How is this intent to increase (CLEAN) Energy production by eliminating wastes impacting our environment, and our overall health and the future of our planet?
Today’s (Incinerator) power plants produce more toxic gasses ie; CO2 than fossil fuel plants: 65 percent more CO2 per megawatt hour than modern coal plants and 285 percent more CO2 than natural gas combined cycle plants (which use both a gas and steam turbine together).
In addition, burning wood biomass emits as much, if not more, air pollution than burning fossil fuels—particulate matter, nitrogen oxides, carbon monoxide, sulfur dioxide, lead, mercury, and other hazardous air pollutants—which can cause cancer or reproductive effects.
The air pollution from incinerator facilities, which the American Heart Association and the American Lung Association have called a danger to public health, produces respiratory illnesses, heart disease, cancer, and developmental delays in children.
Harvesting and removing limbs, leaves and plant parts from forests, which would normally recycle nutrients back into the soil as they decay, can diminish soil fertility and hasten erosion. Heavy machinery used for logging compacts soil and increases runoff, which may affect water quality. Removing vegetation from the ground also impacts wildlife habitats on the forest floor.
Recently, the EPA over the last two years have been reassessing the climate impacts of biomass conversion through a new process and new machines designed by US Green Energy, LLC. http://USgreenrg.com These new machines are now being ordered from governments all over the world and US Green Energy is struggling to keep up.
it is still not clear how (GARBAGE) energy will eventually be regulated, but a decision is expected this year. The EPA has been working with scientists to develop formulas so that states and power plant owners can calculate the climate impacts of wood fuel compared to using garbage instead.
Members of the U.S. Senate recently proposed an amendment to the Energy Policy Modernization Act that would deem forest biomass “carbon neutral.” Under President Trump’s Clean Power Plan to reduce greenhouse gas emissions from power plants, this measure would make biomass equivalent to zero-emission wind and solar energy as a competitive replacement for coal.
In response, 65 scientists and stakeholders wrote a letter to the Senate protesting that “Granting carbon amnesty to ALL forest biomass burning for energy could lead to significant depletion of U.S. forests. The potential implications of declaring carbon neutrality for forest bio-fuels are great because even small quantities of bio-energy require large quantities of wood. The U.S. Energy Information Agency estimates that for each 1 percent added to current U.S. electricity production from forest biomass an additional 18 percent increase in U.S. forest harvest is required. This policy would also encourage or lead to the destruction of forests in developing countries that would see the U.S. as an export market….John Nehmatallah of US Green Energy states ” Wouldn’t it make more sense to convert the enormous amount of Global garbage into Energy?” – US Green, llc.
We urge you and other members of the Senate to reconsider this legislation and eliminate the misrepresentation that incineration is anywhere near carbon-neutral.” And BioMass Conversion is Not. US Green Energy, LLC. Has proven to be the exception to the rule by 0 emissions, 0 gasses into the atmosphere and absolutely 0 Harmful run-off into the ground, aquifers, lakes, rivers or streams.
As the thinking about biomass continues to evolve and the process gets cleaner and cleaner, state, federal, and international regulations need to clearly distinguish between the types of biomass energy plants that are beneficial and those that are detrimental. Treating all refineries, regardless of its source, as carbon neutral, could lead to increased greenhouse gas emissions at home and around the world.
As the scientists said in their earlier letter to Congress, the “Globally improper accounting of bio-energy could lead to large-scale clearing of the world’s forests… any legal measure to reduce greenhouse gas emissions must include a system to differentiate emissions from bio-energy based on the source of the biomass.”
US Green Energy has solved this problem by producing incredible amounts of daily energy by turning the world’s garbage into a sustainable energy source and reducing the overall sedimentary organic compounds that have been poisoning our planet for the past 150 years. If this process and machinery was adopted by other governments, US Green Energy, LLC. Could in Fact eliminate the planets’ garbage stockpiles in only a few short years.
