The Internet has become so common that many of us have difficulty imagining what it takes to realize this digital world, including the number of servers and necessary for its operation. Most data centers around the world rely heavily on fossil fuels to produce the electricity and cooling needed to run the necessary equipment, what some call the "dark side" of the Internet.

The Internet has become so common that many of us have difficulty imagining what it takes to realize this digital world, including the number of servers and necessary for its operation. Most data centers worldwide rely heavily on fossil fuels to produce the electricity and cooling necessary to run the necessary equipment, what some call the "dark side" of the Internet. The statistics are eloquent in that regard: a single search generates 20 mg of CO2, while an email between 0,3 and 4 g. Thus, The 192 billion emails we send annually are equivalent to the footprint of 3,1 million cars per year. Estimates show that the Internet consumes around 1037TWh of electricity worldwide, which represents the production of dozens of nuclear power plants worldwide. This finally represents 609 million tons of greenhouse gas emissions, equivalent to the emissions of all civil flights for one year.

In this context, Bioenergy has a lot to offer, either by providing electricity or heating and cooling solutions. A great example showing such synergies can be found in Luxembourg, near the city of Bissen, where the Kiowatt plant operates.

Kiowatt uses wood to produce electricity, heating and cooling. The project started in 2011 a Luxembourg energy contractor and a Belgian company of the wood and bioenergy industry, decided to create a joint venture to take advantage of all the benefits of bioenergy.

Inside the Kiowatt plant, it all starts with a 17 MW boiler designed to use local wood waste that had not been used before. The boiler is equipped with a turbine to produce heat and energy. The electricity produced, around 21 GWh, is sold directly to the grid. The heat, which represents the most substantial energy produced (93 GWh) is used in three key applications: drying wood for wood pellet production, feeding the district heating of the industrial estate around the plant and, finally, two DataCenter refrigerators located in the polygon that provides a renewable source of cooling.

In 2013, this synergy was the first of its kind in Europe. Today, Kiowatt offers 15 full time jobs on the site and contributes quite significantly to the renewable energy goals of Luxembourg. According to expert estimates, 350.000 tons of CO2 will not be emitted thanks to the project, which contributes to a direct reduction of almost 15% of the GHG emission targets for the country!

In the article you can find a didactic example that explains why biomass emissions are different than those of fossil fuels.

There is a important difference between the carbon dioxide (CO2) emitted by heating diesel, natural gas and other fossil fuels and CO2 emitted by renewable energy sources such as biomass. Both emit CO2 when burned, but in terms of climate change, the impact of that CO2 is very different.

To understand this difference, it is useful to think small and scale. It is useful to think in your own garden.

A tree, every year for 30 years.

Imagine you are lucky to have a garden with space for 30 trees. Three decades ago, you decided to plant a tree every year, every year. In this example, each tree grows to maturity for thirty years, so today you find a flowering grove with 30 trees in different stages of growth, ranging from one year to 30 years.

At 30 years of age, now, the oldest tree has reached maturity and you cut it, for example at the end of winter, before the sap rises, and you let the wooden logs dry during the summer. Plants a new seedling in its place. During spring, summer and autumn, the 29 trees and the new seedling continue to grow, absorbing carbon from the atmosphere to do so.

Winter comes then and to combat the cold, dry wood is burned to keep warm. Burning it will emit carbon into the atmosphere. However, at the end of winter, the other 29 trees plus the sapling he planted will be in exactly the same stage of growth as the previous year; They contain the same amount of wood and, therefore, the same amount of carbon.

Whenever a tree is talented and replanted every year in a 30-year cycle, the atmosphere will not see additional CO2 and will have used the energy captured by its growth to heat your home. Using only what grows is the essence of sustainable forest management.

If you didn't have your dry wood to burn, you may have been forced to burn coal, diesel or gas to heat your home. In the course of the same winter, these fuels would have emitted carbon into the atmosphere that accumulates endlessly, causing climate change.

Your tree management not only provides you with an endless renewable fuel supply, but you can also enjoy other benefits, such as the shelter provided by their trees and the diversity of wildlife they attract.

No carbon added

This is a simplified example, but the principles are valid if your forest contains 30 trees or 300 million; The important point is that with these renewable carbon emissions, as long as less wood is extracted from the one that is growing and the trees that are cut down are replaced, new carbon is not added to the atmosphere. That does not happen with fossil fuels. To be equally renewable it is true that he could have chosen not to have trees, and instead, he could build a wind turbine or install solar panels in his garden. That would be another perfectly reasonable option, but you will still need to use other fuels when the sun does not shine or when the wind does not blow. Worst of all, you don't get all the other benefits a forest brings: seasonal beauty and habitat that maintains wildlife.

In Europe, biomass comes from our forests that we deal with Sustainable Forest Management.

The control of moisture in biomass fuel is essential to reduce fuel costs and achieve higher production yields. Ibertonics presented its near-infrared moisture reader at Expobiomasa with clear advantages over traditional methods.

Most wood chip boilers are designed to run on fuel with moisture content of a defined range. By feeding the fuel that is outside this tolerated range, the boiler causes inefficiency, which increases emissions or can generate an error in the control system.

Therefore, controlling the amount of moisture in wood products is a critical concern of the forestry industry. An excess of humidity can have great impacts on the quality and production of the final product. With a humidity sensor, manufacturers of wood products (splinters, pellets, ...) can adjust humidity levels in real-time information, reducing raw material and fuel costs, higher yields and more uniform products.

La Near infrared moisture measurement is a contactless measurement It offers clear advantages over traditional methods, being the easiest to use, eliminating all manual steps of collecting, drying and precise weighing of samples.

The biomass moisture sensor must be installed in a sturdy support on the conveyor or the processing line. In this way, the sensor can administer continuous readings throughout the process of creating minerals. This guarantees continuous process monitoring, which can be controlled manually or automatically.

Humidity sensors, such as the one presented at Expobiomasa by IBERTRONICS, the IR-3000 of MoistTech allows you to perform moisture measurements in continuous, instantaneous and contactless mode, providing:

  • Reduced energy cost
  • Reduced purchase cost.
  • Drying control.
  • Increased productivity
  • 100% product inspection.
  • Explosion risk reduction.
  • ROI immediately.

A biomass boiler that allows the LC Paper company to manufacture structured tissue paper products with neutral CO2 emissions.

This boiler was the last step of a challenge that began more than a decade ago, when the company rethought all the elements of the production process in order to be able to make paper without emitting carbon dioxide. Achieving "zero emissions" is an important milestone, the result of the objectives of reducing the consumption of energy, water and raw materials.

In traditional tissue paper processes, the manufacture of a ton of paper consumes about 3.000 kWh By redesigning the Manufacturing process , LC Paper has reached a final consumption of only 1.100 kWh per ton. This achievement has been possible thanks to the replacement of a gas boiler with a new industrial biomass boiler with a steam generation capacity of 4.000 kg per hour This will reduce the consumption of 2.930 kW of natural gas, substantial savings, while consuming 1,26Tons per hour of wood chips (8.000 tons per year) of certified forest sustainability wood near the "zero kilometer biomass" factory.

In two years, Galicia will quadruple its installed capacity for biomass consumption, from the current 476.000 tons to 1,7 million tons, according to the report of the timber chain presented by the Axencia Galega da Industria Forestal (Xera) .

Galicia is entering a time when the resources of the mountain charge a new value. Climate change requires reducing fossil fuel consumption, which encourages the take-off of alternatives such as the use of residual forest biomass for energy production. In two years, Galicia will quadruple its installed biomass consumption capacity, from the current 476.000 tons to 1,7 million tons, according to the report of the timber chain presented by the Axencia Galega da Industria Forestal (Xera).

If one considers that the Galician mountain produces between 1,5 and 2 million tons of logging remains every year, the conclusion is clear. The remains of short will soon become a coveted resource in the bush. The first step of demand will rise in early 2020, when the biomass electric power production plant that Greenalia is assembling in Teixeiro (Curtis, A Coruña), which is expected to consume more than 500.000 tons of remnants of remains, enters into operation. felling

This project will be followed by different initiatives of the forestry industry to increase its consumption of logging debris and by-products of its manufacturing process. The board factories have planned replace your current fuel cogeneration system with biomass, with which they generate heat for their industrial process and electricity for the network. That change, together with the increases in consumption of Ence Navia and those that Ence Pontevedra may undertake, will bring about an increase in the installed capacity to use the residual biomass of another 700.000 tons in 2021.

The equation is completed with the biomass power plant that Forestalia is raising in El Bierzo and that will theoretically supply part of its demand in the Galician market from 2020, as assessed in the Xera report, in which it is calculated that the total demand for Galician forest biomass for energy uses can be around 2 million tons in 2021.
