The portion of sewage sludge utilised thermally has risen steadily in recent years. To improve resource utilisation, phosphorus recovery from sewage sludge will also become mandatory from 2029. According to the current state of the art, this recovery is mainly possible from the residues of thermal processes.<\/p>\n<p>A large portion of non-recyclable residual waste is thermally treated in waste incineration plants, one of the main pillars of waste disposal in Germany, in order to generate electricity and heat.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-92ca10c elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"92ca10c\" data-element_type=\"section\" data-e-type=\"section\" data-settings=\"{&quot;jet_parallax_layout_list&quot;:[]}\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-e60e5cc\" data-id=\"e60e5cc\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-31e5888 elementor-widget__width-initial elementor-widget elementor-widget-image\" data-id=\"31e5888\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"577\" height=\"1024\" src=\"https:\/\/www.vgbe.energy\/wp-content\/uploads\/2024\/01\/RollUp_Therm23-577x1024.jpg\" class=\"attachment-large size-large wp-image-29326\" alt=\"\" srcset=\"https:\/\/www.vgbe.energy\/wp-content\/uploads\/2024\/01\/RollUp_Therm23-577x1024.jpg 577w, https:\/\/www.vgbe.energy\/wp-content\/uploads\/2024\/01\/RollUp_Therm23-169x300.jpg 169w, https:\/\/www.vgbe.energy\/wp-content\/uploads\/2024\/01\/RollUp_Therm23-768x1363.jpg 768w, https:\/\/www.vgbe.energy\/wp-content\/uploads\/2024\/01\/RollUp_Therm23-865x1536.jpg 865w, https:\/\/www.vgbe.energy\/wp-content\/uploads\/2024\/01\/RollUp_Therm23-1154x2048.jpg 1154w, https:\/\/www.vgbe.energy\/wp-content\/uploads\/2024\/01\/RollUp_Therm23.jpg 1280w\" sizes=\"(max-width: 577px) 100vw, 577px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-b0204c9\" data-id=\"b0204c9\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-aceee37 elementor-widget elementor-widget-text-editor\" data-id=\"aceee37\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>In Germany, waste, biomass and sewage sludge are mainly thermally processed in grate firing and fluidised bed combustion plants.

By the end of this decade, the district heating supply should be completely, i.e. 100 %, converted to green energy sources.<\/p>\n<p>Matthias Trost and Alexander Trost demonstrated the necessity of maintaining expansion joints in refractory construction, such as in fluidised bed furnaces, with impressive examples and solutions. 70 % of damage to refractory linings is caused by expansion restriction, triggered by inadequate design, installation, operation and maintenance.<\/p>\n<p>The construction and commissioning of the \u201cThermal sewage sludge utilisation and P-recycling in Hamburg\u201d by Harald Han\u00dfen dealt with the commissioning phase, which took significantly longer than expected, meaning that regular operation cannot commence until the first quarter of 2024. The process concept has proven itself. Phosphoric acid is currently produced discontinuously with a degree of purity that enables marketing of the highly demanded phosphoric acid.<\/p>\n<p>The first day of the conference ended with a joint evening event.
