Many paper mills in Central Europe are very dependent on fossilfuels. This is the main reason why Holmen Paper's two mills are so much better than the average when it comes to CO 2 (eq) emissions from energy use. CO 2 (eq) emissions, or "mass of carbon dioxide equivalents", is a measurement that includes the impact from all applicable green ...

Wang et al. [ 4] optimized the coal mill by minimizing the energy consumption using a neuralnetwork model and genetic algorithm. They built a radial basis function (RBF) neural network model, which used the main factors that affected the power consumption as input variables, for determining the energy consumption.
1. Introduction. The pulp and paper industry (PPI) presents an energyintensive sector, which accounted for approximately 6% of global industrial energy consumption in 2017 (International Energy Agency (IEA) 2020a; International Energy Agency (IEA), 2020b).Regardless of a continuous increase in renewable fuel use, pulp and paper mills still rely on fossil fuels and emit a significant amount of ...
Coal is the most abundant fossil fuel on Earth. Its predominant use has always been for producing heat energy. It was the basic energy source that fueled the Industrial Revolution of the 18th and 19th centuries, and the industrial growth of that era in turn supported the largescale exploitation of coal deposits. Since the mid20th century, coal has yielded its place to petroleum and natural ...
The energy consumption of the total grinding plant can be reduced by 2030 % for cement clinker and 3040 % for other raw materials. The overall grinding circuit efficiency and stability are improved. The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended.
In general, energy in the textile industry is mostly used in the forms of: electricity, as a common power source for machinery, cooling and temperature control systems, lighting, office equipment, etc.; oil as a fuel for boilers which generate steam; liquefied petroleum gas; coal; and city gas.
