It is about helping to close the circle of the very good-sounding circular economy , rethinking how more energy and material efficiency can be obtained from these products. In some treatment plants it is relatively common to recover nutrients such as nitrogen or phosphorus. But it is a minority in Spain and Europe, for example, where the guidelines for building and operating treatment plants are still fundamentally defined by a community directive dating back to 2000 and which, although it was seminal in improving the treatment of discharged wastewater today seems modest, almost insufficient, given the advances seen in the last 20 years. By the way, I learned that in this course! Thus, in small countries, where waste and energy and resource dependence can cause serious problems, there is more interest in these topics. Recently, for example, I have been in contact with a project in Taiwan , where a recycling park is being built that will manage all the industrial and domestic waste generated in a city of 2 million inhabitants, converting them into various lines of recycled materials, with zero waste. final, zero net emissions and producing electrical energy equivalent to the consumption of 60,000 homes. The private sector is also , for example, the Malaga cleaning company Arjimsa , which deals with tourist establishments, offices, schools, etc., is developing new models that convert the traditional passive retirement of garbage in an active collection of useful materials, managing them and recirculating them through attractive revaluation channels.
It would be good to see that these initiatives gain weight and that waste management centers, usually operated by public companies or under public concessions, are encouraged to Myanmar Email List rethink their role in the materials process chain and take on the role of sustainability catalysts of the they would be able. What place does bioenergy occupy in the renewable energy sector? Its importance worldwide is very variable depending on the different technologies and raw materials used. The use of woody materials such as firewood or pellets to generate heat is very important, reaching more than 90% of renewable heat generation in Spain in 2018 , according to the Association of Renewable Energy Companies (APPA), and almost 70% of the primary energy of renewable origin in the world, according to the World Bioenergy association. If we talk about the place of bioenergy in global energy consumption, the numbers are much more modest: only 3% of global transportation was powered by biofuels in 2018 , according to the International Energy Agency, and of the total energy consumed in the European Union in 2016, only 7.5% came from bioenergy, according to the Chatham House institution. In Spain, the contribution is so marginal that it tends to be grouped with other technologies in the “other sources of renewable energy” section.
This group contributed 1.6% of the national electricity demand in Spain in 2018, according to the APPA. These numbers, however, should not be discouraging. Personally, I do not believe that the role of bioenergy in a future society that is primarily fueled by renewable energies is to be a majority energy source, with the exception of heat generation. But for other uses, bioenergy should have, from my point of view, a small role in numbers, but enormous in its potential to create a more efficient, smarter, and more equitable energy system. I think we are not fully aware of the enormous amount of clean energy that we can obtain on a sustained basis from resources such as the sun, water or wind. Already in 2013 , just before the shameful move against renewables by the political and economic elites of our country, wind power was the main source of electricity in Spain , according to the APPA . However, these majority renewable energies (hydraulic, solar and wind) present two major structural problems: first, they are generated “passively”, when there is sufficient availability of wind, sun and water. Thus, droughts, less windy seasons or less solar radiation can cause deficits.
