Bleaching mechanical pulp is not a major cause for environmental concern since most of the organic material is retained in the pulp, and the chemicals used hydrogen peroxide and sodium dithionite produce benign byproducts water and, eventually, sodium sulfaterespectively. However, the bleaching of chemical pulps has the potential to cause significant environmental damage, primarily through the release of organic materials into waterways. Pulp mills are almost always located near large bodies of water because they require substantial quantities of water for their processes. An increased public awareness of environmental issues from the s and s, as evidenced by the formation of organizations like Greenpeaceinfluenced the pulping industry and governments to address the release of these materials into the environment.
One of the key drivers in the manufacturing recovery is the renaissance in domestic production of natural gas and, to a lesser extent, oil.
Growth in domestic energy production, driven by the deployment of new exploration and drilling technologies, has been an economic turning point in the US for a number of reasons.
The substitution of natural gas for coal in electricity production and process heat in manufacturing, as well as the growing use of natural gas in transportation, also contribute to lowering greenhouse gas emissions.
For example, shapers of energy policy need to consider which segments will be affected by higher or lower energy costs, how great the impact is likely to be, and what magnitude of difference will trigger a location decision. About the U.S. Electricity System and its Impact on the Environment. The U.S. electricity system; most Americans receive their electricity from centralized power plants that use a wide variety of energy resources to produce electricity, such as coal, natural gas, nuclear energy, or renewable resources such as water, wind, or solar energy. The findings, reported in Nature, state that the new polymerization process uses 10 orders of magnitude less energy and can cut two orders of magnitudes of time over the current manufacturing process.
Finally, overall economic growth is strengthened considerably by the energy boom. Not only is the United States producing more energy, it will also be building more petrochemical refineries, will supply the equipment needed to build the exploration and refining infrastructure, and almost every energy user—from households to large manufacturers—will benefit from more secure supplies and lower costs.
Manufacturing is at a pivotal point in this emerging energy economy. It uses about one-third of all energy produced in the United States, so lower prices and more secure supply give almost all firms in the sector a competitive advantage over firms in other nations.
Relative to the United States, the spot price of natural gas is nearly three times more expensive in Europe and four times more expensive in most of Asia.
This advantage is especially important in the chemicals industry, which is the second largest subsector of US manufacturing. Natural gas and associated liquids represent over 80 percent of the feedstock for US refineries, whereas in Europe and Asia the ratios are roughly two-thirds oil and one-third natural gas.
When the price differential between natural gas and oil is taken into account, the advantage to the American chemicals sector comes into much sharper relief. The US manufacturing sector benefits in many other ways: Finally, a larger share of GDP for a growing manufacturing sector helps to improve living standards, since productivity growth is so strong in this sector.
Sincemanufacturing productivity has grown at an annual rate of 3. In the last few decades, manufacturing — which faces steadily growing foreign competition and must innovate to protect its market share — has steadily improved the energy efficiency of production. Total carbon emissions in this sector have fallen by nearly one-fourth sinceeven though total output has increased by about a third.
As a result, carbon emissions per dollar of output in manufacturing have fallen by 36 percent sincecompared to only 20 percent in the overall economy. This is due in part to the substitution of natural gas, in part due to productivity increases, and in part due to higher use of renewable energy—manufacturing uses 90 percent more renewables than the transportation sector.
Are these trends in energy production and manufacturing sustainable? What are the sectors most likely to benefit?
What are the environmental consequences of this transformation? What policy decisions would strengthen or weaken these trends? Come join our panel on Wednesday to explore these questions.

The biggest contributor to most impact categories — larger in most cases than the upstream, and component and battery manufacturing stages combined — was the electricity grid.
Environmental Impact by Source All energy sources affect the environment. There is no such thing as a completely “clean” energy source.
Getting the energy we need affects our environment in many different ways. Moreover, even for U.S. solar manufacturing, the impact of the tariff may not be significant given the already high competitiveness gap compared to other global players.
