This includes wood waste from the packaging industry, construction and demolition. Wood from so-called municipal waste &#8211; i.e. waste from households, public institutions and companies &#8211; is also included.<\/p>\n<p>So at first glance, waste wood is really just waste &#8211; or a byproduct of other manufacturing processes. At second glance, however, there is a lot of potential in it. That&#8217;s why scrap wood doesn&#8217;t just end up in a landfill site and rot away &#8211; on the contrary, it&#8217;s put to good use. Thanks to special sorting and processing methods, a valuable and climate-friendly secondary raw material is created for energy generation; for example, in the form of wood chips or wood pellets.[\/vc_column_text][\/vc_column][vc_column width=&#8221;1\/2&#8243;][vc_single_image image=&#8221;2272&#8243; img_size=&#8221;full&#8221;][\/vc_column][\/vc_row][vc_row full_width=&#8221;stretch_row&#8221; kd_background_image_position=&#8221;vc_row-bg-position-top&#8221; css_mobile=&#8221;.vc_custom_1659627639858{padding-top: 60px !important;}&#8221;][vc_column]<header class=\"kd-section-title col-lg-12 text-left  subtitle-below-title    vc_custom_1672391929365\" ><h3 class=\"separator_off\" >Waste wood: The recycling miracle<\/h3><\/header>[vc_column_text css_animation=&#8221;none&#8221; css=&#8221;.vc_custom_1672392046746{padding-top: 20px !important;}&#8221;]In Germany, around 80 percent of waste wood is used in central waste wood power plants, mainly to generate electricity but also heat. The remaining 20 percent is recycled &#8211; mainly into particleboard.<\/p>\n<p>Waste wood is thus a showcase example of maximum recycling and makes an enormous contribution to climate protection. After all, this type of sustainable raw material utilization saves around 66 million tons of CO2 in Germany (source: <a href=\"https:\/\/altholzverband.de\/2018\/05\/31\/altholzverwertung-in-deutschland\/#:~:text=Seit%202005%20besteht%20zudem%20ein,stofflich%20oder%20energetisch%20verwertet%20werden.&amp;text=Die%20Qualit%C3%A4t%20des%20Altholzes%20entscheidet,oder%20energetisch%20genutzt%20werden%20k%C3%B6nnen.\" target=\"_blank\" rel=\"noopener\">Altholzverband<\/a>).<\/p>\n<p>Another advantage: waste wood does not cost much.

In contrast to use in centralized large-scale plants, these CHP units support the path of the energy transition toward decentralized generation of energy where it is used. This makes particular sense for companies or facilities that have a constant year-round demand.<\/p>\n<p>The use of waste wood in a biomass cogeneration plant is particularly interesting for <strong>wood-processing companies<\/strong> such as sawmills or furniture manufacturers. This is because they produce their own fuel virtually on the side: the waste wood is a by-product of ongoing production. Instead of exporting it at great expense or disposing of it, a biomass cogeneration plant can convert it into heat and electricity to supply the company itself.<\/p>\n<p>It could hardly be more <strong>efficient, sustainable and climate-friendly<\/strong>.<\/p>\n<p>But buying in waste wood is also highly attractive for companies. Compared to other raw materials, wood chips based on waste wood are not only more climate-friendly, but also cheaper. Energy generation with waste wood makes particular sense for companies that are located near sawmills or other wood-processing companies.
